Throttle/Pedal Position Sensor/Switch C Circuit Range/Performance Problem
The vehicle's throttle position sensor is reporting an incorrect value.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The throttle position sensor talks to the engine computer to tell it how far you're pressing the gas pedal. If it reports an odd signal, the engine can't respond properly.
What the computer is actually seeing
The engine control module (ECM) expects a signal that varies between 0.5V (pedal not pressed) to 4.5V (full throttle) but is seeing a value outside this range, indicating a performance issue.
What a healthy reading looks like
0.5V to 4.5V for the throttle position sensor, roughly correlating to 0% to 100% pedal position.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Inspect the wiring and connectors for the throttle position sensor; look for signs of wear or damage. If any issues found, repair as necessary.
- 22. Check the throttle position sensor signal with a multimeter; expected voltage should range from 0.5V to 4.5V depending on pedal position. If the voltage is out of this range, proceed to step 3.
- 33. If voltage is outside the expected range, replace the throttle position sensor and retest. If the issue persists, check the ECM and resistances in the wiring harness.
Common causes
- Faulty throttle position sensor
- Wiring issues between the sensor and the ECM
- Potentially contaminated or damaged connectors
- ECM issues

Frequently asked questions
Is it safe to drive with this code?
It's moderate severity, so you should fix it soon. It can cause drivability issues.
Will this code come back after I clear it?
If the underlying issue isn't resolved, yes, it will keep returning.
Why does this code pair with P2130?
P2130 also deals with the throttle position sensors and indicates a correlation problem between two sensors.
