If the car is not working for some time, the temperature (the sensor G72) intake air should be as ambient temperature, but mine is a difference of about 10 degrees. The ambient temperature was about 0 degrees and the air inlet temperature around 10 degrees.


when the engine is running what could be the difference in intake air temperature and ambient temperature.

But I have same reading when engine is running and when engine is off.

Engine not running about 10 hours
Ambient temp. = 0
Int. temp. = 10

after driving about 100 km

Ambient temp. = 0
Intake temp. = 12



Is this ok or G72 is faulty.
