P1320 INFINITI 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
How do I fix code P1320 INFINITI
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.
P1320 INFINITI Tech NotesThe most common cause that will trigger the P1320 code is the ignition coils, one or more ignition coils may have failed. Even tough the coils may be working OK, the resistance for one or more of the coils is greater or smaller that what the Engine Control Module (ECM) is expecting. Measuring the resistance with the coil out of the vehicle may not show any failures, usually the coil fails under heavy conditions (hard acceleration) or certain temperatures.
The P1320 code means that there is problem with the "Ignition Coil" or the wire to the ignition coil. For some models without individual ignition coils the Ignition Coil is inside the distributor and the distributor need to be replaced to fix the problem.

Cost of diagnosing the P1320 INFINITI code
Labor: 1.0The cost of diagnosing the P1320 INFINITI 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 INFINITI code detected?When the ignition signal in the primary circuit is not sent to Engine Control Module (ECM) during engine cranking or running.
P1320 INFINITI Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P1320 INFINITI 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.
