What are the possible causes of DTC P1320 Nissan?

NOTE: The listed causes may not be a complete list of all potential problems and there may be other causes.

Nissan P1320 Code Technical Notes

The most common cause that will trigger the P1320 code is the ignition coils – one or more ignition coils may be failing. Even if the coils are operating properly, the resistance of one or more coils is higher or lower than expected by the Engine Control Module (ECM). Measuring resistance with the coil out of the vehicle may show no failure – typically the coil fails under harsh conditions (hard acceleration) or at certain temperatures.

The P1320 code means there is a problem with the “ignition coil” or ignition coil wire. For some models without individual ignition coils, the ignition coil is located inside the distributor and the distributor must be replaced to resolve the issue.

What does Nissan P1320 code mean?

The ignition signal from the Engine Control Module (ECM) is sent and amplified by the power transistor. The power transistor activates and deactivates the ignition coil primary circuit. This on-off operation induces the appropriate high voltage in the coil secondary circuit. The Diagnostic Trouble Code (DTC) will be set when the ignition signal in the primary circuit is not sent to the engine control module during engine starting or operation.

What does code P1321 mean?

Multi-Air is an electronically controlled variable intake valve timing and lift system. Unlike conventional variable intake valve timing and lift systems that control all cylinder intake valves simultaneously and in the same proportion; Multi-Air, through the use of an electronically controlled hydraulic link between the camshaft and the intake valve, allows each intake valve to be controlled independently. Valve lift and timing can be continuously adjusted.
The Multi-Air valve system features a mechanical camshaft lobe acting on a hydraulic pump located between the camshaft intake lobe and the intake valve. The pump supplies pressurized oil to a two-way electro-hydraulic valve called the Variable Valve Actuator (VVA) solenoid. The VVA solenoid is electronically controlled during the specific intake cam lobe event by the Powertrain Control Module (PCM). During the event, the VVA solenoid is commanded to either maintain oil pressure or to bleed off oil. The VVA solenoid is a normally open solenoid. The PCM provides 12 volts to close the solenoid. The position of the VVA solenoid determines the intake valve timing and lift. This change in valve action is similar to creating a change in the camshaft lobe profile affecting valve lift and opening duration.
The Diagnostic Trouble Code (DTC) will be set when the PCM measures the time required to energize the VVA solenoid. When the PCM determines that the VVA solenoid activation time cannot be measured, a fault is set.

What does Hyundai P1321 code mean?

The glow plug indicator is used to warn the driver when the glow plug is operating. The indicator light turns off when battery voltage is low. The glow duration and indicator light activation are fully controlled by the injection computer based on engine operating conditions. Glow plug operation begins immediately when the ignition is turned on. Post-heating involves alternately powering the glow plugs after engine start. However, the glow plug indicator does not illuminate during post-heating. All glow phases, except initial glow and start preparation glow, are canceled when the engine stops. Then, the glow plug indicator is illuminated for at least the duration of the initial glow and start preparation phase by the Engine Control Module (ECM).
