The common symptoms include issues with acceleration, decreased power, stalling, and in some cases, the vehicle may go into "limp mode."

This means that the Engine Control Module (ECM) has detected a higher than normal voltage signal from the throttle or pedal position sensor in circuit 'B.'

Possible causes include a faulty throttle position sensor, a damaged wiring harness, a poor electrical connection, or issues with the ECM itself.

While the vehicle may still be drivable with this code, it is important to address it promptly to prevent potential safety hazards and further damage to the engine.

It is not recommended to continue driving your vehicle with this code, as it can lead to poor performance, reduced fuel efficiency, and potential safety concerns.

Diagnosis typically involves using a scan tool to read the code, testing the throttle position sensor, inspecting the wiring for damage, and checking for loose connections.

Repair tips include replacing the faulty throttle position sensor, repairing any damaged wiring, ensuring all connections are secure, and clearing the code to see if it returns.

While some aspects of diagnosing and repairing this code can be done by a DIY enthusiast, it is recommended to seek professional help for accurate diagnosis and proper repair.

The cost of repairing this code can vary depending on the cause of the issue, the parts needed, and labor costs. It is advisable to get a few quotes from reputable mechanics.

Resetting the ECM may temporarily clear the code, but if the underlying issue is not fixed, the code is likely to return. It is crucial to address the root cause of the problem for a permanent solution.
