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