How do you change the oxygen sensor on 1988 Mercedes 190 E 23?
Located under the passenger side of the car in the exhaust pipe before the catalitic convertor. The wires go through the transmission tunnel and into the loom under the passengers foot well. There is a plastic relay cover panel under the front passengers carpet, remove this to locate the 4 wire connector for the O2 sensor.
not to be mean but fords dont have iat sensors they have a map sensor and it is located in the intake tube between the throttle body and the air filter WRONG!!! The IAT sensor, or the air change temp sensor is located on the right side of the lower intake, right behind the the very first injector on that side.
