Troubleshooting PID 103
There are two possible causes for this fault code:
- Failed sensor.
- Sensor too close to the turbo shaft (not enough air gap).
103 07 – Turbo No Revolution Fault
Troubleshoot a Turbo No Revolution fault as follows:
- With the engine stopped and at ambient temperature, unplug the TSS from the TSS connector. See Figure "Turbo Speed Sensor Location" .
- Measure the resistance between the sensor terminals. See Figure
"Turbo Speed Sensor Terminal and Wire Locations"
Figure 1. Turbo Speed Sensor Terminal and Wire Locations
- If resistance is approximately 900 Ω, refer to "18.104.22.168 Required Action" .
- If resistance is zero or higher than 950 Ω, replace the sensor.
Resolve a Turbo No Revolution fault as follows:
- Remove the TSS from the turbo shaft housing. See Figure "Turbo Speed Sensor Location" .
- Adjust the air gap by adding a 0.020 in. washer between the sensor body and the housing.
- Install the sensor into the turbo shaft housing.
- Start the engine and check for active codes.
