Learn how to diagnose your M102 engine using a simple way. As soon as you are sure that your fuel pump, fuel pressure regulator, fuel distributor, the injectors, the air flow meter plate and the central position of the plunger in the distributor are good functional you can check the electronics. For this test you need a simple wire which you are going to stick in the contacts 1&3 in the diagnostic socket. Based on the number of beats coming from the ECU you will be able to know which part is nonfunctional. This method concerns the TPS(throttle position sensor) open and closed, CTS(coolant temperature sensor), voltage on the potentiometer, lambda probe, EZL(RPM signal), current to the EHA. Learn how to find your issue easy, how you can know if you have one and how to erase the existing error in the system.
