Sensor For Transmission RPM, 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
Requirements
- Respective fuses must be OK:
- Battery voltage must be at least 11.5 volts.
- All electrical consumers such as, lights and rear window defroster must be switched off.
- Parking brake must be engaged.
- Selector lever must be in -P- position.
- Ground (GND) connections to transmission must be OK.
- Ignition switched off.
Test sequence
- Disconnect 16-pin harness connector -2-.
Observe safety precautions.
- Check harness connector for contact corrosion and ingress of water.
If harness connector is not OK:
- Repair the malfunction.
- Erase DTC memory of Transmission Control Module (TCM), Diagnostic mode 4: Reset/erase diagnostic data. Diagnostic Mode 4: Reset/Erase Diagnostic Data
- generate readiness code. Monitors, Trips, Drive Cycles and Readiness Codes
If harness connector is OK:
- Check resistance of Sensor for transmission RPM -G182-.
Check sensor resistance.
- Check sensor resistance between terminals 1 + 10 at 16-pin connector to transmission.
Specified value: 0.8 to 1.2 KOhms
If specified value is not obtained:
- Replace Sensor for transmission RPM -G182-:
- Erase DTC memory of Transmission Control Module (TCM), Diagnostic mode 4: Reset/erase diagnostic data. Diagnostic Mode 4: Reset/Erase Diagnostic Data
- generate readiness code. Monitors, Trips, Drive Cycles and Readiness Codes
If specified value is obtained:
- Check wires to Transmission Control Module (TCM) according to wiring diagram.
Checking wires to Transmission Control Module (TCM)
- 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 16-pin connector to Transmission Control Module (TCM) for open circuit according to wiring diagram.
Terminal 1 + socket 42
Terminal 10 + socket 14
Wire resistance: max. 1.5 Ohms
- Check wires for short circuit to each other.
Specified value: Infinite Ohms
If no malfunctions are found in wires:
- Replace Transmission Control Module (TCM) -J217-.
