In vehicles with a spark plugless ignition system and without a distributor, each cylinder is equipped with an ignition coil. Each coil is attached to the spark plugs using a silicon cable or sleeve. The operation of these consists of a constant supply of battery voltage and a ground pulse from the Powertrain Control Module (PCM). This creates a high-intensity spark required to fire the spark plug in each cylinder. Other vehicles have ignition systems that use coil packs, in which multiple spark plugs are fired from a single coil pack.
Regardless of which ignition system the vehicle is equipped with, the PCM has the control to synchronize and monitor the spark operation. It uses input signals from the CKP (Crankshaft Position Sensor) and the CMP (Camshaft Position Sensor) to monitor spark timing.
The setting of the DTC code P1320 OBDII shows that the PCM found a malfunction in the primary signal of the ignition system. This voltage usually refers to circuits that deliver voltage to ignition coils, coil packs, and not to spark plug wires.
The reasons for the configuration of the fault code P1320 OBD2 are
To solve the failures of the diagnostic code P1320 OBDII, you must take into account the following:
