Codes Often Seen With This Symptom
Browse →The ECM is not receiving a proper signal from the crankshaft position sensor. This sensor is critical for engine timing and fuel injection.
The crankshaft and intake camshaft positions are not synchronized on bank 1. This indicates a timing problem that can cause rough running or no-start conditions.
The fuel pump relay or primary circuit has a fault. The fuel pump may not be getting power.
No signal from the camshaft position sensor on bank 1. Needed for sequential fuel injection and ignition timing.
The engine computer cannot control the variable valve timing solenoid on bank 1. This affects engine performance and fuel economy. Usually caused by a faulty VVT solenoid or wiring issue.
The intake camshaft on bank 1 is more advanced than the ECM commanded. This typically means the VVT system is stuck or the oil flow is restricted. Often caused by dirty oil or a stuck VVT solenoid.
The intake camshaft on bank 1 is more retarded than commanded by the ECM. This reduces engine performance and efficiency. Often related to oil viscosity issues or a failing VVT actuator.
The ECM detected a fault in the exhaust camshaft VVT solenoid circuit on bank 1. This solenoid controls exhaust valve timing for optimal performance and emissions.
