DTC P0353: Ignition Coil No. 3 Primary Circuit: Description

Ignition coil primary circuit is monitored with battery voltage more than 8 volts during engine cranking or more than 13 volts with engine running at less than 3000 RPM, and no coils in dwell when checked. DTC will set in Powertrain Control Module (PCM) memory when PCM senses peak current is not achieved with battery based dwell plus 1.5 milliseconds of diagnostic offset. DTC P0353 takes less than 3 seconds to set with engine cranking, or up to 6 seconds with engine running. Possible causes are: Automatic Shutdown (ASD) relay output circuit open or shorted to ground, capacitor(s) shorted to ground, ignition coil driver circuit open or shorted to ground, defective ignition coil No. 3 or defective PCM.
