Brake Pedal Position Sensor Temperature Sensor Range/Performance Problem
Problem with the brake pedal position sensor's temperature readings.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The brake pedal position sensor measures how much the brake pedal is pressed. If it's too hot or malfunctioning, the computer gets confused about the brake status.
What the computer is actually seeing
The brake pedal position sensor sends voltage signals based on pedal position. If it runs outside expected temperature limits (e.g., under -40°C or above 125°C) or gives erratic readings, you'll set this code.
What a healthy reading looks like
Expected voltage should range from 0.5V (pedal up) to 4.5V (pedal fully pressed). Ideal temperature should be between -20°C and 85°C.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 1Check brake pedal position sensor wiring for damage or corrosion. Repair any found issues. Decision: If wiring is okay, proceed to the next step.
- 2Inspect the brake pedal position sensor connector for corrosion or loose connections. Clean or secure as necessary. Decision: If connector issues were present and resolved, clear codes and test. If still active, proceed to the next step.
- 3Measure voltage at the brake pedal position sensor with the key on, engine off. Expected voltage 0.5V to 4.5V. Decision: If voltage is out of range, replace the sensor. If within range, test the temperature readings next.
- 4Check the temperature of the brake pedal position sensor with a scan tool. Ensure it’s between -20°C and 85°C. Decision: If it's outside this range, replace the sensor. If it reads good, further diagnostics on the PCM may be needed.
Common causes
- Damaged wiring or connectors to the brake pedal position sensor
- Faulty brake pedal position sensor
- Excessive heat from nearby components affecting sensor readings

Frequently asked questions
Is it safe to drive with this code?
Moderate severity suggests fixing soon, but driving is possible if brakes work normally.
Will this code come back after clearing?
If the underlying issue isn't fixed, yes. Monitor the system after repairs.
Why might this code show up with other codes?
Faults in brake systems can lead to multiple sensor errors due to shared wiring or common failure points.
