What P0225 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. P0225 is the general circuit fault of sensor C without telling low from high (those are P0227/P0228). Ford sets it when the digital sensor of the second throttle body has been faulty for more than 4 s and switches on the warning light and the powertrain fault lamp; communication faults of the sensor line have their own codes. The result is reduced power.
P0225 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 P0225
- Check engine light and powertrain fault lamp
- Reduced power
- Rough idle, jerking
Common causes of P0225
- Most likelySensor C or second throttle body faulty
- Most likelyWiring or connector (supply, signal line)
- Possible5 V reference disturbed
- Less likelyEngine module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0225 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). |
| 25 | The exact fault in that area. |
What to do next
- Note P0225 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 P0225
What does P0225 mean?
P0225 means "Throttle/Pedal Position Sensor/Switch C Circuit". 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 P0225?
Drive gently and only to a workshop. With P0225 the car can go into limp mode (reduced power) to protect itself.
Will P0225 fail an emissions test?
Yes, it can. P0225 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 P0225 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 P0225 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
