How does the throttle position sensor work on a 1992 Toyota?
The throttle position sensor, or TPS, in the 22Re engine of your 1992 Toyota sends voltage signals to the engine computer to determine the angle position of the throttle plate inside the throttle body. Depending on the voltage signal from the TPS, the 22Re computer adjusts fuel volume delivery for better engine efficiency.
How do you change the TP sensor on a Toyota?
Touch the two lowest pin connectors on the TPS electrical connector with the two meter probes again. Now, the display on your meter should show a blank screen or infinite resistance. Otherwise, you need to replace the TP sensor.
Can a bad check engine light be a bad TPS?
The check engine light will randomly turn on and off even if the car is running smoothly without any jerks and stalling. This is often the first ever symptom of a bad TPS. Using a code reader, you should be able to confirm whether a faulty TPS is the culprit or a different component.
What are the symptoms of a bad throttle position sensor?
A faulty throttle position sensor sends incorrect information to the ECM resulting in various issues in the engine, its performance, and fuel economy. Below are common symptoms of a faulty TPS. In most of the cases, all of these symptoms will show together making it easier to detect the faulty component. 1) Car Jerks
Can a bad throttle position sensor cause idle surging?
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. At idle, the ECM will not get the correct information and the throttle will variate randomly causing idle surges. 3) Check Engine Light
What does a 22RE throttle position sensor do?
Depending on the voltage signal from the TPS, the 22Re computer adjusts fuel volume delivery for better engine efficiency. If you suspect problems with the TP sensor, you can troubleshoot it at home without special equipment.
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.
