E36 Intake Air Temperature Sensor Location

Alpina b3 3 2 e36 air intake afe stage my ecu sensor iat hiii sir.

E36 intake air temperature sensor location.

The engine coolant temperature sensor is responsible for sending the temperature of the engine to the dme and the instrument cluster. I have bmw alpina b3 3 2 e36 97 i bought the magnum force air intake afe stage 2 but i feel no change in my car performance just sound do i need software or remaping my ecu and there s a. Replace the intake air temperature sensor on my bmw quick fast and in a hurry. It s typically located in the intake manifold but may be in the airbox assembly on some models.

It is a four wire sensor with two separate circuits one for the instrument cluster and one for the dme. This is the m50 s50 m60 and m70 intake air temp sensor iat sensor for e36 325i m3 e34 530i 540i that sends intake temperature data to the ecu so it can correct for abnormally high or low intake temps. The intake air temperature iat sensor is integrated into the e46 m3 stock maf location inside the intake tube and although the oem location works it is prone to heat soak which will allow the ecu to pull timing resulting in power loss.
