OBD-II Generic Error Code P0222: How to Fix It

Q: Can I drive with a P0222 code?

It is not recommended. The vehicle may have reduced power, poor acceleration, or stall unexpectedly. Continued driving could cause safety issues or damage to other components.

Q: What is the difference between P0222 and P0122?

P0222 refers to sensor 'B' (often the second TPS on the throttle body), while P0122 refers to sensor 'A'. Both indicate low input, but they correspond to different circuits. Check your vehicle's wiring diagram for exact pinouts.

Q: Do I need to replace the entire throttle body?

In most cases, only the TPS sensor can be replaced separately. However, on some vehicles, the TPS is integrated into the throttle body, requiring replacement of the whole unit. Check your repair manual.

Q: How much does it cost to fix P0222?

DIY cost is typically $20-$100 for a new TPS sensor. Professional repair can range from $150-$400 depending on labor and parts.

Q: Will a bad TPS cause transmission problems?

Yes. The ECM uses TPS data for shift scheduling. A faulty TPS can cause harsh shifting, delayed shifts, or incorrect gear selection.

Abstract

Code P0222 indicates that the engine control module (ECM) has detected a low voltage signal from the throttle position sensor (TPS) 'B'. This sensor tells the computer how far the gas pedal is pressed. A low input usually means a wiring issue, a faulty sensor, or a throttle body problem, potentially causing poor acceleration or stalling.
