P1320 Possible Causes
- Faulty power transistor unit built into ignition coil
- Ignition primary circuit is open or shorted (circuit to ignition coils)
- Ignition primary circuit poor electrical connection (circuit to ignition coils)
- Faulty ignition system condenser
- Crankshaft position sensor circuit
First diagnose P1320 code
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 terminals.
Cost of diagnosing the P1320 code
Labor: 1.0The cost of diagnosing the P1320 code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.
When is the P1320 code detected?When the ignition signal in the primary circuit is not sent to Engine Control Module (ECM) during engine cranking or running.
P1320 Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P1320 MeaningThe ignition signal from the Engine Control Module (ECM) is sent to and amplified by the power transistor. The power transistor turns on and off the ignition coil primary circuit. This on-off operation induces the proper high voltage in the coil secondary circuit.
