What is the function and installation process of the Intake Manifold Temperature Sensor on the BMW X5?

The Intake Manifold Temperature Sensor (IAT) sensor, mounted on the top of the intake manifold, adjusts the fuel mixture and timing with reference to intake air temperature. This NTC (negative temperature coefficient) sensor works in a manner that inversely to the temperature, the resistance passing through the sensor reduces. If the intake air temperature signal is invalid, a DTC is set and if the OBD II fault criteria is achieved, the MIL turns ON. In such cases, the ECM uses the aforesaid command signal in combination with the engine coolant temperature (ECT) sensor signal as backup. To reach the sensor power and ground, one needs to turn off the vehicle engine and take the intake manifold cover off. Disconnect the electrical connection to the Intake Manifold Temperature Sensor and, on the side of the temperature sensor, there will be a locking clip that should be pressed and the sensor pulled directly backwards out of the intake manifold. The installation is done in the reverse manner to the removal where a new sealing O-ring is used at the base of the sensor and assembled with the aid of assembly lubricant. Last but not the least, tighten the connector and scan the computer for any codes and erase as well as reset the ECM memory as may be required.

BMW X5 Intake Manifold Temperature Sensor

BMW X5 Intake Manifold Temperature Sensor is applied to ensure the engine computer fine-tunes the combustion process by reporting in real time the conditions of the air intake. Within each BMW powertrain, the Intake Manifold Temperature Sensor delivers information to the PCM, which uses this information together with the signals from the mass air flow circuit to make the necessary decisions to determine precise fuel injector on time and stay within the ideal air fuel ratio for each driving situation. A dirty hot wire in the Intake Manifold Temperature Sensor or a stuck door in earlier vane style versions can cause the ECU to misinterpret airflow and in the case of a BMW, may cause hesitation when you accelerate, unexpected stalling, or mixtures that run noticeably rich or lean. When the sensor fails in any X5, the PCM records a diagnostic trouble code and the check engine light lights up. Unmetered air sneaking by the sensing point in the intake tract of an X5 will deceive the Intake Manifold Temperature Sensor into signaling less air than is actually present, thus causing a lean condition. It is therefore essential to check for a leak carefully when evaluating the issue of an X5 Intake Manifold Temperature Sensor on every BMW X5.
