Diagnostic Aids

WARNING: This page is about a different car, the 2016 Cadillac ATS. However, it is still accessible from the selected car via links, so may be relevant.

With RPO LF3 or LF4, this 5-pin MAF/IAT sensor is in the intake air duct farthest from the front of the vehicle, for rear wheel drive vehicles it is on the passenger side. Only the MAF function of this sensor is used by the ECM.
