Circuit Description
WARNING: This page is about a different car, the 2007 Isuzu i-370, 2007 GMC Canyon, and 2007 Chevrolet Colorado. However, it is still accessible from the selected car via links, so may be relevant.
The ignition system uses individual ignition coil/module assemblies for each cylinder. The powertrain control module (PCM) controls the individual coils by transmitting timing pulses on the ignition control (IC) circuit of each ignition coil/module to enable a spark event. The PCM monitors each IC circuit for improper voltage levels. Each ignition coil/module has the following circuits:
- An ignition voltage circuit
- A ground
- An IC circuit
If the PCM detects an improper voltage level on the IC circuit of the ignition coil/module, it will set the corresponding DTC.
- DTC P0351 for ignition coil/module 1
- DTC P0352 for ignition coil/module 2
- DTC P0353 for ignition coil/module 3
- DTC P0354 for ignition coil/module 4
- DTC P0355 for ignition coil/module 5
