This simplified wiring diagram of the ignition system applies only to 1992, 1993, 1994 and 1995 2.2L Toyota Camry.
Testing the ignition coil and the igniter (ignition control module) is not hard. I've written two tutorials that'll help you diagnose them in a step-by-step way. You can find them here:
- How To Test The Ignition Coil (1992-1995 2.2L Camry).
- How To Test The Igniter (1992-1995 2.2L Camry).
Igniter Circuit Descriptions
The Igniter (ignition control module) has 5 wires coming out of its connector. Each one has a specific job to do and here's a brief description of each:
|1992-1995 2.2L Camry Igniter Connector|
|1||White with red stripe||IGF -Ignition coil firing feedback signal|
|2||White||IGT -Igniter control signal|
|3||White with red stripe||Bat + -Battery power|
