P0226 — Throttle/Pedal Position Sensor/Switch C Circuit Malfunction
Drive with caution — fix soon.
What P0226 means
This code means there's a general malfunction in the third throttle or pedal position sensor circuit (sensor C), so its signal isn't reliable. It's typically caused by a failing sensor, damaged wiring, or a corroded connector in that circuit. Repairs usually involve testing the circuit and replacing the sensor or fixing the wiring, and it's generally fixable without major engine work.
Common symptoms
- Check engine light is on
- Engine drops into reduced-power mode
- Hesitation or poor throttle response
- Rough idle or stalling
- Inconsistent acceleration
Common causes
- Faulty throttle/pedal position sensor (C circuit)
- Damaged or shorted wiring
- Corroded or loose connector
- Poor ground or power supply to the sensor
- Faulty throttle control module
Typical repair cost
$120 – $420
Varies by vehicle and root cause.
Frequently asked questions
Can I keep driving with a P0226 code?
For short trips, usually yes, but the car may limit power for safety. Since throttle response can be affected, it's best to get it checked promptly rather than relying on it.
How much does it cost to fix a P0226 code?
Most repairs land between $120 and $420. Replacing the throttle position sensor is the most common fix, while wiring or connector repairs can shift the cost.
Is a P0226 code serious?
It's moderately serious. The car often still runs, but unreliable throttle behavior is a safety concern, so it shouldn't be ignored.
What is the 'C' circuit in this code?
Some throttle systems use three position sensors that cross-check each other. The 'C' circuit refers to the third of these, and P0226 means the computer detected a fault in that specific sensor circuit.
