Hydraulic Pressure Sensor Circuit Intermittent

Where it lives

For P0936, the circuit described runs through the sensor. The description of P0936 reports a fault at the sensor.

Check these first

• A hydraulic pressure sensor connector losing contact
• Chafed pressure sensor wiring near the transmission
• A pressure sensor element failing when hot
• A loose pressure sensor mounting

What to do next

1. Road test and watch hydraulic pressure sensor data
2. Wiggle test the pressure sensor connector and harness
3. Watch the reading as the fluid warms
4. Check the pressure sensor mounting and hardware
5. Replace the sensor if the signal drops
6. Clear the code and retest
