YAW RATE SENSOR MALFUNCTION
The yaw rate sensor is having a malfunctioning issue.
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)
Inside the vehicle's stability control system, the yaw rate sensor measures the angle and speed of rotation around the vertical axis. It helps the car understand if it's sliding or turning too sharply.
What the computer is actually seeing
The computer looks for a stable signal from the yaw rate sensor that reflects the car's movement; if it sees erratic changes, it flags a code.
What a healthy reading looks like
A normal yaw rate reading should stay within ±3 degrees per second during steady driving conditions.
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 for DTCs besides C1371 that might help identify the problem.
- 2Inspect wiring to the yaw rate sensor for damage or wear.
- 3Check connectors for corrosion or misalignment; repair as needed.
- 4Using a scan tool, monitor the yaw rate sensor data in real time. It should output a steady reading during normal driving conditions.
- 5If the sensor reading is erratic, replace the yaw rate sensor; if readings are normal, check other stability control components.
Common causes
- Bad yaw rate sensor
- Wiring issues to the sensor
- Corroded connectors
- Poor ground connection

Frequently asked questions
Is it safe to drive with C1371 active?
It's advised to fix this soon; you may experience traction control issues but the vehicle is drivable.
Will C1371 come back after clearing?
It can return if the root cause isn't fixed; if the sensor is faulty or wiring issues exist, it will likely reappear.
Why does this code pair with C1370?
C1370 often indicates a related issue with the yaw rate sensor performance; both codes suggest a malfunction in the stability control system.
