Toyota Celica/Corolla Ignition Coil Issues

The document summarizes a technical service bulletin for Toyota Celica and Corolla models from 1999-2005 that experience stalling issues. Codes P1300, P1305, P1310 and P1315 indicate issues with the ignition coils. Testing showed a faulty new ignition coil was shorting the ignition control signal wire, causing all coils to register errors. Replacing the defective coil resolved the stalling problem.

Preocupación del Cliente: The vehicle starts and stalls. Codes P1300, P1305, P1310 and P1315 are all
stored in the computer. A new cam sensor crank sensor and computer has been
tried. The vehicle has spark.
Millaje Promedio Reportado: 140112
Pruebas/Procedimientos: 1. At any coil/igniter assembly, check to see if there is 5 volts on the
Blue/Yellow IGF wire with the key in the on position.

2. Disconnect all the ignition coils and check to see if the 5 volts comes
back.

3. At the engine control computer, locate the Blue/Yellow wire and remove
the wire from the connector or cut the wire away from the connector. Check
to see if the 5 volt reference comes back.
Consejos Tecnicos: The computer sends out a 5 volt reference to each ignition coil when the key is
turned on. The igniter taps this wire to ground to confirm spark is happening.
Since each igniter shares the same wire if the wire shorts out or an ignition coil
shorts this wire, the vehicle will set a code for each igniter. Turns out that a new
coil they installed was faulty. An original coil was shorted and all 4 were replaced.
but they had the same problem. In the end one of the new coils was shorting the
IGF terminal to ground.
