P0227 — Throttle/Pedal Position Sensor/Switch C Circuit Range/Performance Problem
Drive with caution — fix soon.
What P0227 means
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.
Common symptoms
- Check engine light is on
- Engine enters reduced-power or limp mode
- Hesitation when pressing the gas
- Rough or unstable idle
- Erratic engine speed
Common causes
- Worn or faulty throttle/pedal position sensor (C circuit)
- Dirty or sticking throttle body
- Damaged wiring or corroded connectors
- Poor ground or electrical connection
- Faulty throttle control module
Typical repair cost
$120 – $420
Varies by vehicle and root cause.
Frequently asked questions
Can I keep driving with a P0227 code?
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.
How much does it cost to fix a P0227 code?
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.
Is a P0227 code serious?
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.
What does 'range/performance' mean in this code?
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.
