Location of the electronic control unit ECM in the car
The electronic control unit (ECM) receives signals from various sensors that monitor the changing operating modes of the engine, such as the volume of air entering the engine, air temperature, coolant temperature, engine speed, deceleration or acceleration of the vehicle and the oxygen content in the exhaust gases. These signals are used by the ECM to determine the correct duration of fuel injection and to set the required ignition timing angle.
If any sensor fails, the system enters backup mode and ensures engine operation, but with less efficiency.
The ECM is located under the instrument panel behind the glove box. To remove the ECM, you must remove the glove box and the instrument panel trim under the glove box.
