On newer engines, the Crank Shaft Position Sensor performs this function. Fault Code Description 12 - No Distributor reference pulse (diagnostic test active) Symptoms When flashing the Check Engine Light to read codes, code 12 will always display first, indicating the diagnostic system is active The engine will not run with a "hard" code 12 set Common Problems Chances are you will never need to diagnose a code 12. Rather, the problem would be a crank, no-start condition. If code 12 does not flash, that would indicate a communication problem with the ECM. Code 12 does not show when reading codes with a scan tool. If there is a communication problem, the scan tool will let you know. Related Items:What needs to be done?

First things first, your check engine light is on and/or your car is running incorrectly. First thing you do is pull the code form the engine. You can get a code reader to do this (I have one myself - it was given to me), or you can do this the free & easy way. Keep on reading for more information.The ECM is constantly monitoring engine conditions. It is constantly adjusting and controlling how your engine works and performs. If there is an engine malfunction detected by any one of the numerous sensors connected to the ECM, a trouble code will be stored in the memory, and your check engine light will be triggered. To pull the code from the ECM, you will need to locate your ALDL (Assembly Line Diagnostic Link) connector. It is normally located right under the dash around the steering wheel area to the right.This is what the ALDL connector looks like:A: GroundB: Diagnostic TerminalM: Serial Data[/color][/b]Turn on the car (DO NOT START IT*) and use a paper clip or a piece of wire to jump terminal A & B. DO NOT TRY TO START THE CAR*! You will see the SES (Service Engine Soon) light flash out a code. It will flash out each code three times. The first code you will get will be a code 12*. It will be a single flash, followed by a short pause, then
