Ignition Codes

Ignition Coil C Primary/Secondary Circuit Malfunction

Fault in ignition coil C (cylinder 3).

Ignition Coil E Primary/Secondary Circuit

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

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 D Primary/Secondary Circuit Malfunction

Fault in ignition coil D (cylinder 4).

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.

Camshaft Position Sensor A Circuit Range/Performance

CMP sensor signal is present but outside expected range.

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.

Ignition Coil A Primary/Secondary Circuit Malfunction

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

Ignition Coil B Primary/Secondary Circuit Malfunction

Fault in ignition coil B (cylinder 2).

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 Coil H Primary/Secondary Circuit

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