- Ignition Coil 4 harness is open or shorted
- Ignition Coil 4 circuit poor electrical connection
- Faulty Powertrain Control Module (PCM)
How do I fix code P0354 PONTIAC?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Cost of diagnosing the P0354 PONTIAC code
The cost of diagnosing the P0354 PONTIAC code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
When is the code detected
Each ignition circuit is continuously monitored by the Powertrain Control Module (PCM). The test fails when the PCM does not receive a valid pulse signal from the ignition coil.
Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power
- Engine may be harder to start
- Engine hesitation
- Rough engine idle
P0354 PONTIAC Description
The ignition system on the vehicle uses inpidual ignition coils for each cylinder. The Powertrain Control Module (PCM) controls each ignition coil operation. The PCM sends a ON/OFF signal to energize the ignition coil to create a spark at the spark plug when a spark is required at the cylinder.
