Electronic Ignition (EI) Module
ELECTRONIC IGNITION (EI) MODULE
REMOVAL

1. Ignition Off.
2. Remove air induction resonator.
IMPORTANT: Note which spark plug wire is removed from which coil tower. The spark plug wires must be connected to the correct coil towers.
3. Remove two upper EI module bolts.
4. Using a small, flat-bladed screwdriver, remove spark plug wires from the coil tower by gently prying between the FT module and the black connector position assurance (CPA) housing.
5. Disconnect EI module harness connector.
6. Remove two lower EI module bolts.
INSTALLATION
NOTE:
^ Verify threads of bolts, mounting surface and threaded holes are clean and free of any residue.
^ Use care when installing the EI module bolts. Make sure the bolt head is seated on the EI module when the torque specification is reached. If the bolt head is not seated on the ignition module, remove the bolt and tap the hole to clean any debris from the threads.
^ Over torquing of the EI module will result in cracking the coil housing and damaging the coil.

1. Install EI module and lower two bolts.
Torque:
EI Module Bolts: 8 N.m (71 in-lbs)
2. Connect EI module harness connector. Push in connector until a click is heard and pull back to confirm a positive engagement.
3. Insert plug wires into CPA(s). Connect spark plug wires with CPA(s) to the coil towers.
4. Install upper two EI module bolts.
Torque:
EI Module Bolts: 8 N.m (71 in-lbs)
IMPORTANT: Orientation of the wires to the EI module is critical to the operation of both the module and On-board diagnostics. The orientation from left to right is 4 1 2 3.

5. Install air induction resonator.
