Camshaft Position Actuator Circuit Open (Bank 1)

The ECM has detected an open circuit in the camshaft position actuator (VVT solenoid) on Bank 1. This controls variable valve timing.

Camshaft Position Timing Over-Advanced Bank 1

The camshaft timing is more advanced than commanded by the ECM on Bank 1. Often caused by dirty oil or a faulty VVT solenoid.

Camshaft Position Timing Over-Retarded Bank 1

Camshaft timing is more retarded than expected on Bank 1. Similar causes to P0011 but opposite direction.

Camshaft Position Actuator Circuit Bank 1 Exhaust

Fault in the exhaust camshaft position actuator circuit on Bank 1. Affects exhaust valve timing.

Camshaft Position Timing Over-Advanced Exhaust Bank 1

Exhaust camshaft timing is over-advanced on Bank 1.

Camshaft Position Timing Over-Retarded Exhaust Bank 1

Exhaust camshaft timing is over-retarded on Bank 1.

Crankshaft/Camshaft Position Correlation Bank 1 Sensor A

The crankshaft and camshaft position signals are out of sync on Bank 1. This indicates a timing issue.

Crankshaft/Camshaft Position Correlation Bank 1 Sensor B

Exhaust camshaft position signal does not correlate with crankshaft position on Bank 1.

Camshaft Position Actuator Circuit Bank 2

Electrical fault in the bank 2 intake camshaft VVT actuator circuit.

Camshaft Position Timing Over-Advanced Bank 2

Bank 2 intake camshaft timing is over-advanced. The cam is advancing beyond the commanded position.

Camshaft Position Timing Over-Retarded Bank 2

Bank 2 intake camshaft timing is more retarded than commanded.

Fuel Rail/System Pressure Too Low

The fuel pressure in the fuel rail is lower than commanded. This causes a lean condition and can lead to engine damage.

Fuel Rail/System Pressure Too High

Fuel pressure is higher than commanded, which can cause rich running and injector damage.

Fuel Pressure Regulator Performance

The fuel pressure regulator is not maintaining correct pressure.

Fuel Pressure Regulator Circuit Open

Open circuit in the fuel pressure regulator control circuit.

Fuel Pressure Regulator Circuit Low

Fuel pressure regulator control circuit voltage is too low.

Fuel Pressure Regulator Circuit High

Fuel pressure regulator control circuit voltage is too high.

Fuel System Leak Detected — Large Leak

The ECM has detected a large fuel system leak based on a significant, rapid drop in fuel rail pressure that cannot be explained by normal injector demand.

Mass Air Flow Circuit Malfunction

The MAF sensor circuit has a general fault. The ECM cannot reliably read airflow into the engine.

Mass Air Flow Sensor Range/Performance

The MAF sensor is reading airflow outside of expected range for current engine conditions.

Mass Air Flow Circuit Low Input

MAF sensor signal voltage is lower than expected. The ECM thinks less air is entering than actually is.
