TPMS Sensor 1 Position Performance
The tire pressure monitoring receiver cannot reliably localize sensor 1 to a wheel position. Pressure values may be assigned to the wrong wheel until relearn is completed.
Affected components
- Tpms sensor
- Tpms receiver
Common causes
- High likelihood: Position relearn required after rotation
- Medium likelihood: Weak sensor signal at receiver
Possible symptoms
- ABS warning light on
- ESC/stability control deactivated
- Possible reduced brake assist
- Speedometer may behave erratically
