Oil Pressure/Temperature Sensor -G437- OR Oil Pressure/Temperature Sensor 2 -G640-, REMOVING AND INSTALLING: Notes

Special tools and workshop equipment required 

• Socket - 27mm T40218
• Vehicle Diagnostic Tester

Important Safety Precautions 

• The identity of the sensor in the All Wheel Drive Control Module -J492- must be adapted using the Vehicle Diagnostic Tester or the Oil Pressure/Temperature Sensor 2 -G640-.
• Do not replace both the Oil Pressure/Temperature Sensor -G437- and Oil Pressure/Temperature Sensor 2 -G640- at the same time because a valid sensor identity is needed for the rear final drive classification to the All Wheel Drive Control Module -J492-. If the both sensors are replaced at the same time, the All Wheel Drive Control Module -J492- will interpret this as the rear final drive is being replaced. By doing this, adaptation values in the control module will be erased and the performance of the rear final drive will be impaired.
• If both the Oil Pressure/Temperature Sensor -G437- and the -G640- must be replaced due to mechanical damage, for example, if the connector housing gets damaged, then this must be performed in two steps. After replacing the first sensor, the identity must be adapted in the All Wheel Drive Control Module -J492- using the Vehicle Diagnostic Tester. Do the same for the second sensor.
• If both the Oil Pressure/Temperature Sensor -G437- and Oil Pressure/Temperature Sensor 2 -G640- must be replaced at the same time due to an electrical fault, then the clutch classification must be entered into the All Wheel Drive Control Module -J492- using the Vehicle Diagnostic Tester. Also, the ATF in the rear final drive must be replaced. Refer to ATF ON REAR FINAL DRIVE 0BF AND 0BE, DRAINING .
