What should I do if my TPS sensor is not working?
A perfect adjustment won’t stick, but is damn close. Now, while you have your voltmeter connected and reading. Slowly move the throttle to WOT (Wide Open Throttle) and carefully monitor the voltage. It should go steadily up and not “jump” around. If it does jump around or is not a smooth definite increase in voltage, you may have a faulty TPS.
Why is my throttle position sensor not working?
The reason this happens is that the ECM doesn’t get correct information from the TPS as to how much to throttle the car. Idle surging can be caused due to other issues in the car, but if it happens in conjunction with other throttle position sensor symptoms, the culprit is often the TPS.
Is there a way to adjust the TPS?
If you are lucky enough to have a scanner (Auto XRay Scanner) and know how to incorporate this into this adjustment, by all means … go right ahead! Some may also elect on making jumper wires to go from the TPS connector to the TPS and attach the voltmeter, via clip-leads.
How often should a throttle position sensor be replaced?
They are built into the sensor so they can not be replaced like those of a flashlight. Hence, it is recommended by car manufacturers to replace TPS sensors every 5 years to enjoy safe and hassle-free driving. Do not leave it until you’re encountering faulty throttle position sensor symptoms.

How does the TPS work on a throttle position sensor?
The sensor basically looks at idle or closed throttle (IDL) and throttle angle opening (VTA). The TPS itself is simply a linear variable resistor that when driven by the ECU produces a linear voltage in a 0-5 volt range, 0 volts being idle and up to 5 volts representing throttle opening angle.
How can you tell if a throttle position sensor has gone bad?
As we’ve said, engine output is controlled by adjusting the air and fuel mix, and without a throttle position sensor (TPS), the engine cannot tell the right amount of fuel or air to deliver into the engine. So then, how can we tell if the TPS has gone bad? Well, here are eight possible symptoms of a bad throttle position sensor .
What should I check before adjusting my TPS?
This should be checked prior to any adjustment of the TPS. Crankcase vapors are commonly vented into the throttle body for re-introduction into the combustion process (by the Exhaust Gas Recirculation, or EGR, valve). These vapors can leave an oily residue on the back of the throttle pate and allow sludge and dirt to accumulate.
