Drive with caution — fix soon.
This code means the third throttle or pedal position sensor (sensor C) is reading out of its expected range or doesn't agree with the other sensors. Common causes include a worn sensor, a dirty throttle body, or wiring and connector problems in that circuit. Repairs usually involve cleaning or replacing the sensor and inspecting the wiring, and it's typically a manageable fix.
$120 – $420
Varies by vehicle and root cause.
Short trips are usually okay, but the car may limit power to protect itself. Because throttle response is affected, it's best to get it checked soon rather than relying on it for long drives.
Most repairs cost between $120 and $420. A throttle body cleaning is at the low end, while replacing the sensor or fixing wiring costs more.
It's a moderate concern. The car often still drives, but reduced throttle response is annoying and a potential safety issue, so it shouldn't be ignored.
It means the sensor's reading is technically present but doesn't fall within the expected values or match the other throttle sensors. The computer flags this mismatch because it can't trust the signal.
