How do I fix error code P0120?
What repairs can fix the P0120 code?
- Repairing or replacing the TPS connector.
- Repairing the wiring as necessary.
- Replacing the TPS with a new sensor.
What are the symptoms of a bad idle position sensor?
Here are some common symptoms of a bad or failing throttle position sensor to watch for:
- Car won’t accelerate, lacks power when accelerating, or accelerates itself.
- Engine won’t idle smoothly, idles too slowly, or stalls.
- Car accelerates, but won’t exceed a relatively low speed, or shift up.
What could cause a P0120 code?
To give you an idea, here are the possible causes of the P0120 code: Faulty throttle position sensor. Faulty accelerator position sensor. Damaged or corroded wiring or connectors.
Can a bad TPS cause low idle?
What are signs of a bad Throttle Position Sensor? Unstable Engine Idle: Faulty position sensors can cause sporadic idle conditions due to fluctuating airflow. If you see your car misfiring, Idling rough, or stalling out while you drive then you definitely want to have a professional check out that sensor.
What is P2138 code?
The P2138 trouble code indicates that the Engine Control Module has detected a malfunction within the D and/or E circuits of the throttle position sensor.
What does engine code P1516 mean?
throttle position sensor
The code P1516 is is for the throttle position sensor.
What does Engine code P1516 mean?
What percentage should TPS be at idle?
At idle is should be zero or a couple of degrees. Press down on the gas pedal very S-L-O-W-L-Y until the throttle is all the way open. You should see the percentage of throttle opening gradually increase to 100 percent at wide open throttle.

What does the p0120 code on an engine sensor mean?
Just like any other engine sensor, these sensors may fail due to several reasons. P0120 is an error code that indicates a potential fault with one of your vehicle’s TP/APP sensors or the sensor’s circuit. What does the P0120 Code Mean?
What are the p0120 and p2135 codes?
I have 2 codes P0120 and P2135, I first replace the pigtail and TPS sensor same problem and codes (Reduced engine power). so i bit the bullet and replaced the throttle body along with another new TPS (it came attached ) still same problem…any help?… codes P0340 and P0120 please help!
What causes a p0120 TPS a circuit malfunction?
Potential causes of the P0120 code include: Sticking throttle return spring MAP or TPS connector corrosion Misrouted harness causing chafing If you have access to a scan tool, with KOEO (Key on engine off) observe the TPS voltage.
How does the TPS work on a Nissan p0120?
The TPS sends the throttle position information back to the PCM on this signal wire. When the throttle is closed the signal is near .45 volts. At WOT (Wide Open Throttle) the TPS signal voltage will approach a full 5 volts.
