- Remove the cover for the ignition coil.
- Tag and detach the electrical connectors from all 6 ignition coils.
Turn the ignition switch to the
position and measure the voltage at the black/yellow wire for each connector. If voltage is present go to the next step. If voltage is not present, repair the open circuit in the wire between the ignition coil and fuse No. 11 in the left side under dash fuse panel.
Turn the ignition switch
and check for continuity between the black wire and ground. If ground is present, go to the next step. If ground is not present, repair the open circuit in the wire between the ignition coil and the body ground.
Unplug the 31-pin connector from the Powertrain Control Module (PCM). Hold the 31-pin multi-connector such that the wire connectors are visible, with the locking tab on top. The first row of connectors from left to right are numbered 1 through 10. On the second row, the number 11 slot is empty and the remaining connectors are numbered 12 through 22. The third row is numbered 23 though 31, with slot number 24 empty. Check the following wires from the provided pin location for continuity to ground. If there is not continuity go to the next step. If there is continuity, repair the short in the wire between the PCM and the ignition coil.
Blue, pin location No. 3 to ground
Reconnect the PCM multi-plug connector. With the ignition switch in the start position, check for voltage at the multi-plug connector for each ignition coil for the following wires: blue, yellow/green, black/red, yellow, red, and white/blue. If the measured voltage is 0.5 volts, replace the ignition coil. If no voltage is measured, repair the open circuit in the wire between the PCM and the ignition coil.
Removal & Installation
- Disconnect the negative battery cable.
- Remove the intake manifold cover.
Remove the ignition coil covers, if equipped.
- Detach the connector from the ignition coil.
- Remove the ignition coil by removing the mounting bolts.
- Remove the ignition coil.
- Installation is the reverse of the removal procedure. Tighten the coil retainers to 8.7 ft. lbs. (12 Nm).
