What P0226 means
Sensor C is a third throttle or pedal position sensor whose role depends on the manufacturer. Ford uses it for the sensor of the second throttle body on engines with two throttles and digital (SENT) sensors; with other makes it can be a further pedal or throttle channel. P0226 is the plausibility fault: the signal of sensor C is electrically valid but does not match its partner sensor or the airflow model. No manufacturer using exactly this code was found – Ford does not report sensor C plausibility separately. The logic follows the sibling checks on sensors A and B (Bosch: more than 9 % deviation, Ford: more than 7 degrees). The result is limp mode with reduced power.
P0226 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0226
- Check engine light on
- Limp mode, reduced power
- Jerking, poor throttle response
Common causes of P0226
- Most likelyWear or dirt on sensor C or the second throttle body
- PossibleContact resistance at connector or wiring
- PossibleThrottle dirty or sticking
- Less likelyEngine module or software
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0226 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 2 | Area: fuel and air metering (injector circuit). |
| 26 | The exact fault in that area. |
What to do next
- Note P0226 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0226
What does P0226 mean?
P0226 means "Throttle/Pedal Position Sensor/Switch C Circuit Range/Performance". Sensor C is a third throttle or pedal position sensor whose role depends on the manufacturer. It is a generic code, so it means the same on every make.
Is it safe to drive with P0226?
Drive gently and only to a workshop. With P0226 the car can go into limp mode (reduced power) to protect itself.
Will P0226 fail an emissions test?
Yes, it can. P0226 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0226 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P0226 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
