C1280

Moderate

Yaw Rate Sensor Signal Fault

What Does C1280 Mean?

The yaw rate sensor is powered and communicating, but its signal is reporting out-of-range, erratic, or implausible data. Unlike C1279 which indicates a complete circuit failure, this code means the sensor is partially functional but producing unreliable readings. The ESC system cannot trust the yaw rate data and will disable stability control functions.

Common Causes

35%

Yaw rate sensor degraded or failing internally (erratic output, drift)

Yaw rate sensor
Yaw rate/lateral acceleration combo sensor

25%

Sensor mounting loose or improperly positioned causing vibration-induced signal noise

Sensor mounting bracket
Mounting bolts
Rubber isolators

20%

Intermittent wiring connection causing signal dropout or noise

Sensor wiring harness
Connector pins
Harness splice

10%

Electromagnetic interference from aftermarket electronics affecting sensor output

Aftermarket amplifier wiring
Auxiliary electronics
Shielding

10%

Sensor requires re-zero/recalibration after vehicle service or battery disconnect

Yaw rate sensor calibration

Diagnostic Steps

1

Monitor the yaw rate sensor PID in live data with the vehicle on a flat surface and stationary — the reading should be at or very near 0 degrees/second. A significant offset or erratic fluctuation confirms the signal fault.

2

Perform a yaw rate sensor zero-point calibration using the scan tool — this resets the sensor's neutral point. The vehicle must be on level ground, stationary, with the engine running.

3

Physically inspect the yaw rate sensor mounting — it must be rigidly attached to the vehicle body/subframe. Check for loose bolts, cracked bracket, or missing rubber isolators that could introduce vibration noise.

4

With the vehicle stationary on level ground, use a scope on the sensor signal wire and look for noise, dropouts, or drift that would indicate an intermittent electrical connection or failing sensor element.

5

Drive the vehicle in a controlled figure-8 pattern while monitoring the yaw rate PID — it should smoothly track positive during right turns and negative during left turns, returning to zero on straightaways.

Frequently Asked Questions

What does C1280 mean?

What causes C1280?

The most common cause of C1280 (Yaw Rate Sensor Signal Fault) is: Yaw rate sensor degraded or failing internally (erratic output, drift)

How much does it cost to fix C1280?

Typical repair costs for C1280 range from $150 to $700, depending on the vehicle, location, and whether you do it yourself or go to a shop.

Is it safe to drive with C1280?

ESC is disabled due to unreliable yaw rate data. The vehicle lacks electronic stability assistance during skid events. ABS generally remains functional. Avoid aggressive driving, especially on slippery or curvy roads. Repair promptly — a simple recalibration may resolve the issue, but a failing sensor will continue to degrade.

How do I diagnose C1280?

Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to C1280 to identify the root cause.
