G62 engine coolant temperature sensor

 

The coolant temperature sensor of the G62 engine is located near the coolant connection on the cylinder head. It sends information on the current coolant temperature to the J248 direct fuel injection engine control module.

 

 

Signal application

The J248 Direct Fuel Diesel Engine Control Module uses coolant temperature as the correction value to calculate the amount of injection.

 

Consequences of signal failure

If the signal from the coolant temperature sensor of the G62 engine fails, the direct fuel injection engine control module J248 uses the signal generated by the G81 fuel temperature sensor to calculate the amount of injection.
