SYMPTOM
P0353 - IGNITION COIL # 3 PRIMARY CIRCUIT

WHEN MONITORED
With battery voltage greater than 8 volts during engine cranking or greater than 12 volts with engine running, and with engine speed less than 2016 rpm, and none of the coils in dwell when checked.

SET CONDITION
Peak current is not achieved with battery based dwell plus 1.5 msec of diagnostic offset. It takes less than 3 seconds during cranking or up to 6 seconds while running to set.

POSSIBLE CAUSES
- ASD relay output circuit open
- Rear ignition coil terminal observable defect
- Ignition coil # 3 driver circuit shorted to ground
- Ignition coil # 3 wiring harness intermittent defect
- Ignition coil # 3 wiring harness observable defect
- Ignition coil # 3 driver circuit open
- Powertrain Control Module (ignition coil driver)
- Rear ignition coil
