Circuit Description
This engine is equipped with a distributorless ignition system called the Electronic Ignition (EI) system. The primary circuit of the EI system consists of 2 separate ignition coils, an electronic Ignition Control Module (ICM) and a Crankshaft Position (CKP) sensor as well as the related connecting wires and the Ignition Control (IC) portion of the Powertrain Control Module (PCM). Each secondary circuit consists of the secondary winding of the coil, 2 connecting metal strips molded into the coil housing, the spark plug boot/connector assemblies and the spark plugs

Important: The Camshaft Position (CMP) Sensor is only used for a misfire detection and is not part of the ignition system.

Diagnostic Aids
Check for the following conditions:

^ The Throttle Position (TP) sensor binding or sticking in wide open throttle position.
^ The Throttle Position (TP) sensor for a shorted or open circuit.
^ Water or foreign material in the fuel.
^ Low compression (timing chain failure).
^ A slow responding Exhaust Gas Recirculation (EGR) Valve.

Test Description
The numbers below refer to the step numbers in the diagnostic table.

1. The Powertrain OBD System Check prompts the technician to complete some basic checks and store the Freeze Frame Data and the Failure records on the scan tool if applicable. This creates an electronic copy of the data taken when the fault occurs. This information on the scan tool can be referred to later.
7. This verifies that the fuel injectors are receiving the proper voltage.
8. The PCM should turn ON the fuel pump for 2 to 3 seconds after the ignition is turned ON. Turn OFF the ignition for at least 10 seconds in order to assure that the PCM powers down. The PCM will then switch the fuel pump back ON. Whenever the fuel pump does not operate, use the Engine Cranks But Will Not Run (Fuel Pump Circuit) in order to diagnose the cause.
11. The battery voltage should be available at the terminal C of the CKP sensor harness, and the terminal B should be a good ground.
12. By grounding the test light to the terminal B and the B+, ensures the integrity of the ground circuit.
13. The CKP ACT. CNT should go to 256 counts, before starting back at 0. At this point, it is important that the reference CKP, ACT, CNT is incrementing.
14. This verifies a frequency output from the PCM.
15. If the ignition control A and the ignition control B are shorted together, there will not be a frequency signal. This step determines if the ignition control A and the ignition control B are shorted together.
23. Thoroughly examine the CKP sensor connector. It should be free of corrosion and contaminants, and the pins should make proper contact.
26. This will verify if the open circuit is in the ICM or the circuit. Engine Cranks but Does Not Run (Fuel Pump Circuit).
