Ignition Codes

Ignition Coil C Primary/Secondary Circuit Malfunction

Fault in ignition coil C (cylinder 3).

Camshaft Position Sensor A Circuit Malfunction Bank 1

The camshaft position sensor (CMP) on Bank 1 has a circuit fault. This sensor is critical for engine timing.

Ignition Coil A Primary/Secondary Circuit Malfunction

Fault in ignition coil A circuit. Coil A is typically cylinder 1.

Ignition Coil E Primary/Secondary Circuit

Fault in ignition coil E (cylinder 5 on V6/V8 engines).

Camshaft Position Sensor A Circuit Range/Performance

CMP sensor signal is present but outside expected range.

Ignition Coil D Primary/Secondary Circuit Malfunction

Fault in ignition coil D (cylinder 4).

Ignition Coil F Primary/Secondary Circuit

Fault in ignition coil F (cylinder 6).

Ignition Coil G Primary/Secondary Circuit

Fault in ignition coil G (cylinder 7 on V8 engines).

Ignition Coil H Primary/Secondary Circuit

Fault in ignition coil H (cylinder 8 on V8 engines).

Ignition Coil B Primary/Secondary Circuit Malfunction

Fault in ignition coil B (cylinder 2).

Camshaft Position Sensor A Circuit Low Input

CMP sensor signal voltage is too low.

Camshaft Position Sensor A Circuit High Input

CMP sensor signal voltage is too high.

Camshaft Position Sensor A Circuit Intermittent Bank 1

The cam position sensor signal is cutting in and out intermittently, causing timing calculation errors.

Camshaft Position Sensor A Circuit Bank 2

Cam position sensor circuit fault on bank 2 of a V6 or V8 engine.

Ignition/Distributor Engine Speed Input Circuit Malfunction

The engine speed input circuit, which the ECM uses to time ignition and fuel delivery, has a fault.

Ignition Coil Primary/Secondary Circuit Malfunction

A general ignition coil circuit fault has been detected, not isolated to a specific cylinder.

Knock Sensor 2 Circuit Range/Performance Bank 2

The Bank 2 knock sensor signal is out of the expected range.

Knock Sensor 2 Circuit Low Input Bank 2

The Bank 2 knock sensor is reading a lower signal than expected.

Knock Sensor 2 Circuit High Input Bank 2

The Bank 2 knock sensor is reading a higher signal than expected.
