Come join the discussion about performance, modifications, classifieds, troubleshooting, maintenance, and more! You can do it at home in just a few minutes.

Let the sounds of a bad starter help you diagnose and repair your hard-to-start or no-start problem with your car. Check the specs for your particular make and model, if necessary. As you manually open and close the throttle plate, watch the voltage readings at the meter. Look for wire damage and loose wires at the connector. Your vehicle is like your wife.Spend some money on them once in a while and they won't nag you to death.

A drop to infinite resistance at any point indicates a break in the TPS's resistance element and also indicates a bad TPS.

Is one of the wires shorted out? Still no acceleration. Check for trouble codes, even if the check engine light is not on. JavaScript is disabled.

The most typical failure you'll find on a TPS is wear, a short or an open on the circuit of the contacts or variable resistor. Chrysler Sebring 2.0L (DOHC): 1995, 1996, 1997, 1998, 1999. Your DMM should read around 0.2 up to 1.5 Volts or close to it, depending on your particular model. What could be the problem?

While watching the readout on your DMM, gradually open the throttle plate until is fully opened (or have an assistant gradually depress the gas pedal to the floor). As you let go off the accelerator pedal to slow down, the throttle plate closes and of course the TP sensor sends the info to the PCM as it returns to its base voltage signal, till the whole cycle begins again. For example, no voltage signal, a stuck voltage, etc.

It starts normal but will not continue to run.

Make sure the voltage increases smoothly.

Answer: It is possible if the computer didn't receive an expected input from the sensor.

I have changed the throttle body, gas pedal and sensor. A faulty TPS may be the cause of many drive-ability problems.

Is Your TPS Connected to Reference Voltage?1. There are three wires going to the sensor body, the negative ground, the +12 Volt input, and the variable output to the onboard computer. This is the throttle body.

Drove and light is back on.

Thanks so much for your time.

Why doesn't it close? Connect one of the test leads to the center connector, the computer output connector, and the other lead to either the +12 volt or the Ground connector on the TPS connector. Follow the fuel line to the housing mounted over the block of the engine. But it's better to have it diagnosed.

He has certifications in Automation and Control Technology and Technical Writing.

Also, you may need to adjust a stop screw in the throttle body and, still in some other models, adjust a dash pot that prevents the throttle plates from suddenly closing.

Codes read the TPS was bad, so I replaced the throttle body.

It can be either a clogged fuel filter or blocked exhaust system (possibly the cat). Touch the negative probe on the multimeter to the negative wire tab on the TPS and the positive probe to the positive tab. Question: My 2009 Volkswagen Tiguan is throwing a Throttle Actuator Control Range\Performance code.

Question: What is the initial voltage for a throttle position sensor?

Answer: Have the TPS circuit checked. Answer: Check the idle air control (IAC) solenoid.

Codes still say throttle body is bad. Question: My throttle position sensor is not getting ground.

if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[580,400],'easyautodiagnostics_com-leader-1','ezslot_4',128,'0','0'])};if(typeof __ez_fad_position!='undefined'){__ez_fad_position('div-gpt-ad-easyautodiagnostics_com-leader-1-0')};On the Dodge Neon, Plymouth Neon and Breeze, the wire that carries the TP signal to the fuel injection computer is the orange with dark blue stripe (ORG/DK BLU) wire. * Also, if your TPS doesn't reach 5 volts, or close to it (up to 3.5V on some models), when the throttle plate is fully opened, replace the TPS.7.

Dan Ferrell writes about DIY car maintenance and repair. Check the fuel injectors and fuel pressure regulator foe leaks. Dodge Neon 2.0L (SOHC): 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002. You may need the vehicle repair manual for this.

I have changed the throttle body and the entire accelerator pedal (sensor included) and the issue is still there.

Specifications of the top muscle cars from the '60s and '70s. One of the terminals should read 5 volts, or pretty close to it.

Regardless of the DTC found, always conduct the necessary diagnostic to confirm a faulty senosr or circuit as possible. See if this helps.

Would the TPS sensor cause this?

Outside the gilded cageRush Limelight, Home | Answer: Check the user's manual.

Now, as you watch the readings on the multimeter, slowly rotate the throttle plate manually.

Connect the red test lead from your DMM to the battery positive post, the one marked with a "+" sign.6.

However, read the operator's manual to make certain. Turn OFF the ignition key and remove the pins.If your have an adjustable throttle position sensor (old vehicle model), and your readings are out of specification, try to adjust the sensor first before replacing it. If the TPS works correctly, the multimeter will display a reading of about 1/2 of a volt.

Plymouth Neon 2.0L (SOHC): 1995, 1996, 1997, 1998, 1999, 2000, 2001.

This value is what the PCM associates with a closed throttle.

In all of these vehicles, the ORG/DK BLU or BRN/RED wire connect to the female terminal labeled with the number 2 in the image above. There could be problems with the throttle actuator, its position switch, a circuit problem in one of the modules are some of the other reasons for this code.

Make sure the throttle plate is fully closed.5.

The car will drive perfectly normal until the red cog light appears on the dashboard. The voltage should gradually increase from 1 to 5 volts and back to 1 volt. TPS diagnostic trouble codes (DTC's) stored in the vehicle's computer's memory.

Come check it out! On some models, this is actually an idle switch (manual transmission) or wide-open throttle switch (automatic transmission).

Keep the throttle plate at the close position (or at the position specified in your repair or service manual).5. Here's a look at the Cheetah, Chaparral, Shelby Cobra, Corvette Stingray, Shelby Mustang, Cobra Daytona, Devin SS, Griffith, Scarab, Sunbeam Tiger, Early Thunderbird, Arnolt-Bristol, Bocar, Dual-Ghia, Edwards America, Cunningham.

Can you tell me if the values I gave is OK?

I changed gas pedal (TPS) light went out.

Try turn the ignition Off and then On again. Or is this a whole new issue?

This year's facelift of Mercedes-C-class Benz's sports sedan marks a major shift in design and engineering, but the car retains its winning combination of luxury and status at an accessible cost. The multimeter should register 0.4 to 0.6 Volts DC.

The TPS may develop dead spots that the computer is not catching if other conditions are not set. You may want to have a shop scan the computer first before making any decision. A bad part?

Backprobe the position sensor to monitor the voltage signal with your DMM.3. This is an example of an adjustment on an externally mounted TPS.

You may need to trace voltage in the circuit. If the sensor tests OK, erase the code. Question: I own a 2012 Suzuki Eeco minivan.

Instead of a 5-volt reference, it works with a 12v reference. Use a test light. Question: The TPS has 2 wires not 3 wires, why? Do you know if it could be bad, and still not display dash light, and if there is no dash light, would it still possibly throw a code? Question: In the 'connected to ground' test I have two that read about 12v. I. But this will give you a general idea of the adjustment procedure.1. There could also be a problem with the driver on the computer, but this is rarer.

All signs point to a bad throttle position sensor, but it never comes up in the fault codes.

Question: Hi. What should we do to fix it? Once the engine check light shows up, the acceleration power decreases, and I am forced to press the accelerator pedal harder for the engine to respond (and this is resulting in high fuel consumption).

The check engine light is also on.

A jumpy reading will tell you the sensor is failing. Connect the positive (red) test lead from your DMM to the signal wire and the black negative (black) test lead from your DMM to the ground wire.3. Loosen the sensor mounting bolts just enough so that you can rotate it by lightly tapping on it with a screwdriver handle.2. APPLIES TO: This TPS test tutorial applies to the following vehicles (since they use the exact same TPS): You can find all of the 2.0L and 2.4L Chrysler how to test tutorials at: Chrysler 2.0L And 2.4L Index Of Articles. Fortunately, it's not that hard to test the sensor. Once you throw the car in drive and accelerate the car, the throttle opens and the throttle position sensor immediately sends this change of the throttle plate angle as an INCREASING voltage signal to the PCM.

Start with a visual inspection of the wires and connector. Driving a truck is a respectable career move, but you've got to have a nickname. Unexpected stalling, rough idle, hesitation upon accelerating, or unexplained acceleration while cruising at a steady speed are all symptoms of a defective TPS. Now, this doesn't happen very often, but it happens.

Answer: A failed throttle position sensor, or other sensor for that matter, that hasnt failed with the voltage parameters expected by the computer to know it has failed, wont set a trouble code. Also, check for carbon buildup in the sensor itself and the throttle ports where it mounts.

Check the connector for corrosion or build up. Answer: It's possible your alternator is getting "weak".

The TPS and throttle body are one piece. How do I test it? Typically the ground is black, the power is red and the signal wire is a different color, blue for example.

Locate the TPS to the side of the throttle body.

* Also, make sure that the voltage increases smoothly as you gradually open the throttle plate. If you see an erratic or no movement of voltage signal, replace the TPS sensor. Could this mean a relay or perhaps fuse has gone?

Car flipping tips from an experienced successful flipper. You'll need to use a back probe or a wire piercing probe on the signal wire.

* If you notice the voltage skipping or stuck at a certain voltage value, as you gradually open the throttle plate, your TPS is not working properly and you need to replace it.

Inspect the throttle plate and the walls of the throttle body surrounding the throttle plate.

Car only reaches a low, limited speed (lack of power), Gear shifting issues (automatic transmission), Triggering of trouble codes (depending on car model). Volume controls, tone controls, and balance controls are all three-terminal potentiometers. The most common TPS test is to measure for resistance (ohms) or voltage at the various positions, including throttle plate closed, half open and fully open. The other is the signal wire.

Now, if the throttle position sensor code won't go away, take a look at the info found at: TPS Code Won't Go Away for a few more suggestions as to what could be causing the TPS diagnostic trouble code (DTC). Turn the ignition key to the ON position but don't start the engine.4. Answer: Ideally, a faulty TPS would throw a code.

Answer: Check first the fuse and/or relay -- you may need the electrical diagram if there's a short somewhere in the circuit. Volume controls, tone controls, and balance controls are all three-terminal potentiometers.

Answer: TPS code wording usually changes from one manufacturer to the other. Step 6 Plug in the TPS electrical connector, start your engine and test for performance.

This guide will help you test the throttle position sensor in a few minutes and know whether you need to replace it.

Then, the car won't start.

But these symptoms may come from other bad sensors, parts, or components. Turn the ignition key ON but don't start the engine.4. In the video, you will learn what a damaged wheel bearing sounds like and how to determine which wheel bearing is causing the noise.

Still, you need to scan your cars computer for trouble codes and fix the issue according to the diagnostic. You'll have the check engine light (CEL) illuminated on your instrument cluster and one of several of the following symptoms: The throttle position sensor's job is to measure the angle of the throttle plate. What Is a Hall Sensor in a Washing Machine? Assuming black is ground, I also get 'reference' voltage readings close to 5 for the other two wires.

Knowing how to test a throttle position sensor can save you time, and, most importantly, prevent you from changing parts unnecessarily.

Make a note of the color of this wire. Poppy not everyone has an o-scope handy.I've been in the business for many years and I don't even have one.

The TPS is a small plastic block with a three wire connector. Returned it and installed.

When testing electronic devices in your car, use a 10-megaohm impedance digital multimeter to protect sensitive electronic devices in your vehicle. All the world's indeed a stage, and we are merely players, performers and portrayers, each another's audience. Any small jumps are signs for concerned.

With this increasing voltage signal, the PCM knows it's time to inject more fuel, advance ignition timing, and a host of other things it has to do to keep your 2.0L (SOHC & DOHC) vehicle running optimally. Let's examine your TPS signal test result: CASE 1: The multimeter registered a smooth increase or decrease in voltage with no gaps.
