This code indicates that there is an intermittent problem with the throttle position sensor circuit. The throttle position sensor is a device that measures the position of the throttle valve. This information is used by the engine control module to calculate the amount of fuel that needs to be injected into the engine. If the throttle position sensor circuit is not functioning properly, the engine may not run smoothly or may stall.
Symptoms of this code include:
- Engine stalls or idles rough
- Hesitation or jerking during acceleration
- Decreased fuel efficiency
- Check engine light illuminated
To diagnose this code, a technician will typically:
- Inspect the throttle position sensor for damage or contamination
- Test the throttle position sensor circuit for continuity and voltage
- Replace the throttle position sensor if necessary
This code is not considered to be a major problem, but it should be addressed as soon as possible to avoid any potential problems with the engine.
