P0229: Throttle/Pedal Position Sensor/Switch C Circuit Intermittent
Do not keep driving
Have this diagnosed promptly. Unexpected limp mode is the failure mode and it arrives without warning.
What this code means
Sensor C is dropping out intermittently, completing the fifteen throttle and pedal position codes spanning P0120–P0124, P0220–P0224 and P0225–P0229. Read as a group: which sensors report, and whether they report circuit faults or correlation faults, is what separates a wiring problem from a worn sensor from a sticking throttle plate.
Likely causes
Start here
- Intermittent wiring fault · moderate
- Corroded or loose connector · easy
- Worn throttle position sensor track · moderate
Less common
- Chafed harness against engine or bracket · moderate

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
