Intermediate shaft speed sensor C (third intermediate sensor in heavy-duty or hybrid-coupled transmissions) signal voltage below the lower limit.
Affected components
- Intermediate shaft speed sensor c
- Sensor wiring
Common causes
- High likelihood: Signal wire shorted to ground
- Low likelihood: Connector pins corroded - high contact resistance
- Low likelihood: Harness chafing through insulation
Possible symptoms
