The sensor is located in the charge air intake duct. For 1.8L and 2.0L CPLA, CPPA, CPKA, and CPRA engines, the air filter housing assembly must be removed to access the sensor. For all other 1.8L and 2.0L engines, the front of the vehicle should be raised and supported on jackstands, followed by the removal of the engine undercover. Once located, the electrical connector should be disconnected. The sensor fasteners need to be removed or the tabs released, allowing for the sensor to be taken out of the duct. The O-ring should be discarded, and a new one must be used during the installation of the same sensor, which is done in reverse order of removal.
