Coil-on-plug (COP) control circuit - ignition feedback (IGF) signal error


Detection Condition

Possible Causes


[P1364 - From 1995 Mazda Millenia factory service manual]


Notes: 1995-1996 KJ engine management utilizes 4-terminal ignition coils while 1997+ models use 3-terminal coils (missing terminal D).  Using a 3-terminal coil in conjunction with an ECU expecting a 4-terminal coil will result in an open circuit condition for terminal D and P1364 while 4-terminal coils are interchangeable in either application.
