WARNING: This page is about a different car, the 2017 Cadillac ATS. However, it is still accessible from the selected car via links, so may be relevant.
- Ignition OFF, disconnect the harness at the B260 Rear Differential Oil Pressure/Temperature sensor.
- Test for 1.44K-2.43K Ω between the signal circuit terminal 1 and the low reference circuit terminal 2.
- If not between 1.44K-2.43K Ω
Replace the B260 Rear Differential Oil Pressure/Temperature sensor.
- If between 1.44K-2.43K Ω
- If not between 1.44K-2.43K Ω
- Test for infinite resistance between each control circuit terminal listed below and the sensor housing/case:
- Terminal 1
- Terminal 2
- If not infinite resistance
Replace the B260 Rear Differential Oil Pressure/Temperature sensor.
- If infinite resistance
- All OK.
