Here is how to find the code.
NOTE: Not all trouble codes will activate MIL (CHECK ENGINE light)
* Before proceeding, make sure the:
o CHECK ENGINE light circuit is functional. It should be ON when the ignition switch is ON with the engine stopped.
o Battery voltage is above 11 volts.
o Throttle valve is fully closed (Throttle Position Sensor IDL points closed).
o Accessory switches (A/C, etc.) are OFF.
o Engine is at normal operating temperature (if possible).
* Turn ignition switch to ON position.
o Do not start the engine.
o Place a jumper wire across TE1 and E1 terminals in engine check connector.
* Count number of flashes from CHECK ENGINE light.
o If system is operating normally (with no detected faults), the CHECK ENGINE light will blink continuously
and evenly about 2 times a second.
* Otherwise, the light will blink a number of times equal to the trouble code as follows:
o The light blinks only (.5 second ON, .5 second OFF) when indicating a number.
o The light will be OFF for 1.5 seconds between the first digit and the second digit of the code.
o If more than one code is stored, the light will be OFF for 2.5 seconds before the next code is displayed.
o Once all code(s) have been displayed, the light will be OFF for 4.5 seconds and then the whole sequence will repeat.
* The diagnostic code series will continue to repeat as long as the check connecter terminals TE1 and E1 are connected.
* When finished, remove the jumper wire.
* After repairing the malfunction, clear the codes from the ECUs memory.
