What is the throttle position sensor D circuit low input?
Etc and check engine lights are on…giving codes 0642, 2122, 0522, 0335..every once in a while will crank up and run fine for about ten minutes, then etc comes back on and no throttle/ limp mode comes back… Engine won’t rev past 3000 rpm. Cam circ high, code P0343 and Accelerator position circ low, code P2122.
What does a p2122 mean on a TPS sensor?
A P2122 code means that the the car’s computer has detected that the TPS (throttle position sensor) is reporting too low a voltage. On some vehicles that lower limit is 0.17 – 0.20 volts (V). The “D” refers to a particular circuit, sensor, or area of a particular circuit. Did you adjust it when you installed it?
How can you tell if your throttle position sensor is bad?
The most common symptom is your check engine light. This indicator is a vague symptom, as it could also point to a variety of issues, but you can expect to see it if there’s any issue with your throttle position sensor. Next, any unusual changes in your acceleration could be linked to this sensor.
Where is the throttle position sensor on a 3.8L GM engine?
(The tab inside the sensor MUST be touching the rotating pins in the throttle body. In a 3.8L GM engine, this means inserting it with then connector at 12 o’clock before rotating it to 9 o’clock for the final mounting position.)
What does p0122 mean on a TPS sensor?
A P0122 code means that the the vehicle’s computer has detected that the TPS (throttle position sensor) “A” is reporting too low a voltage.
What to do if your throttle position sensor is too low?
Carefully check the throttle position sensor (TPS), wiring connector, and wiring for breaks, etc. Repair or replace as necessary Check the voltage at the TPS (refer to a service manual for your vehicle for specific information). If the voltage is too low that is indicative of a problem. Replace if necessary.
