Wastegate Position Sensor B Circuit Performance
The wastegate position sensor B signal does not correlate with the commanded actuator position within tolerance. Sensor offset, mechanical wear, or signal integrity degraded.
Affected components
- Wastegate position sensor b
- Wastegate actuator
- Ecm
Common causes
- High likelihood: Sensor mechanically offset from actuator
- Medium likelihood: Linkage between sensor and wastegate worn
