Transmission Fluid Temperature Sensor, Checking

Transmission Fluid Temperature Sensor, Checking

Recommended special tools and equipment
- V.A.G 1526 multimeter or V.A.G 1715 multimeter
- V.A.G 1594 connector test kit
- Wiring diagram

Test requirements
- Respective fuses in fuse box must be OK:
- Battery voltage must be at least 11.5 volts.
- Ground (GND) connections to transmission must be OK.
- Selector lever must be in -P- position.
- Ignition switched off.

Test sequence







- Disconnect 8-pin harness connector (arrow -3-).

Checking resistance
- Measure resistance of Transmission Fluid Temperature Sensor -G93- between terminals 1 + 2 at connector to sensor:


ATF temperature Specified value

approx. -30 degrees C 37.0 to 51.0 kohms
approx. 10 degrees C 5.0 to 8.0 kohms
approx. 25 degrees C 3.0 to 5.0 kohms
approx. 110 degrees C 230.0 to 265.0 ohms
approx. 145 degrees C 100.0 to 120.0 ohms

If one of the specified values is not obtained:
- Replace Transmission Fluid Temperature Sensor -G93-.
- Erase DTC memory of Transmission Control Module (TCM), Diagnostic mode 4: Reset/erase diagnostic data. Diagnostic Mode 04 - Erase DTC Memory
- Generate readiness code. Readiness Code

If specified values are obtained:
- Check wires to Transmission Control Module (TCM) according to wiring diagram.

Checking wiring
- Connect test box to control module wiring harness, connect test box for wiring test. Test Box, Connecting For Wiring Test







- Check wires between test box and 8-pin connector to Transmission Control Module TCM) for open circuit according to wiring diagram.
Terminal 1+socket 45
Terminal 2+socket 8
Wire resistance: max. 1.5 ohm
- Also check wires for short circuit to each other.

Specified value: infinity ohm

If no malfunctions are found in wires:
- Replace Transmission Control Module (TCM) -J217-.
