Transmission Fluid Temperature Sensor, Checking

• The Transmission Fluid Temperature Sensor (G93) is a component of the Mechatronic unit in the transmission.

Requirements

• The battery voltage must be at least 12.5 V.

• All electrical consumers must be switched off.

• The parking brake must be engaged.

• The selector lever must be in the "P" position.

• The Ground (GND) connections to transmission must be OK.

- Disconnect the electrical connector in the - direction of the arrow - and remove it from the Transmission Control Module (TCM) (J217).

- Observe safety precautions.

- Check the electrical harness connector for contact corrosion and ingress of water.

If the electrical harness connector is not OK:

- Repair the malfunction.

If the electrical harness connector is OK:

- Check the wiring according to the wiring diagram:

If no malfunctions are found in the wiring:

- Replace the Mechatronic unit in the transmission.

• The Transmission Fluid Temperature Sensor (G93) is a component of the Mechatronic unit and cannot be replaced separately.

- Assembly is performed in the reverse of the removal.

1. Check the DTC memory. Refer to => [ Diagnostic Mode 03 - Read DTC Memory ] Diagnostic Mode 03 - Read DTC Memory.

2. If necessary, erase DTC memory of the Transmission Control Module (TCM) (J217). => [ Diagnostic Mode 04 - Erase DTC Memory ] Diagnostic Mode 04 - Erase DTC Memory.

3. Generate readiness code. => [ Readiness Code ] Monitors, Trips, Drive Cycles and Readiness Codes.
