Code P0320 2002 Ford F150 Description

The Ignition Failure Sensor is used to check whether the spark ignition is occurred correctly or not, and it is also used to tachometer drive. The sensor monitors the voltage difference between a resistance on the battery circuit for the ignition coil. When the ignition coil works properly, the electric current through the resistance is detected as voltage drop. This is confirmed for every ignition event with the crankshaft sensor and the camshaft sensor. If Engine Control Module (ECM) detects a malfunction, no ignition is possible, so the engine would not start. If there is no ignition signal for a predetermined cycle for one or two ignition coils, an ignition coil circuit failure exists.
