Code P0340 Saturn Description
The P0340 code for Saturn vehicles indicates a problem with the camshaft position sensor circuit. The camshaft position sensor plays a crucial role in the engine's operation by monitoring the position of the camshaft and sending signals to the engine control module (ECM) to ensure proper fuel injection and ignition timing. When the ECM detects that the signal from the camshaft position sensor is out of range or missing, it triggers the P0340 code.
Common Causes of P0340 Saturn
- Faulty camshaft position sensor
- Damaged wiring or connectors in the sensor circuit
- Engine timing belt or chain issues
- ECM malfunction
- Poor electrical connections
Symptoms of P0340 Saturn
- Engine misfires or runs rough
- Difficulty starting the engine
- Reduced fuel efficiency
- Engine stalling or hesitation during acceleration
- Illumination of the Check Engine Light
How to Fix P0340 Saturn
- Diagnose the issue by using a scan tool to confirm the P0340 code and test the camshaft position sensor's signal output.
- Inspect the wiring and connectors for any damage or corrosion. Repair or replace as necessary.
- Check the timing belt or chain for proper tension and alignment. Replace if worn or damaged.

On your 2000 model the camshaft position sensor is part of the Ignition Module. See video above.

I have a 2008 Saturn vue and I do not know where to find the ignition module. Would you be able to assist me in locating it. Also would a faulty ignition coil cause the codes P0340 and P0341?

HolA tengo un saturn 2000 sl1-motor 1.9 en el tablero tira la luz de chek i marca el sensor de levas como arreglar ese codigo ya que mi saturn no trae ese sensor que cables rebiso i si me pueden decir donde quedan esos cables para verificar el mal circuito
-
El "Powertrain Control Module (PCM)" usa el "Electronic Ignition (EI) Module " para determinar la posicion de levas.
Entonces comiense por inspeccionar o cambiar las bujias y los cables de las bujias. Si eso esta buen, limpie los connectores de los enbobinads del Electronic Ignition (EI) Module. Si todo esta bien, entonces tiene que cambiar el Electronic Ignition (EI) Module.

I have an 09 Saturn vue 4cyl
I have a p0340 code popping up I’ve replaced both camshaft sensors, crankshaft sensor as well as both int and exh solenoids I’ve also just replaced the timing chain with new guide rods and tensioner! I still have check engine light on after resetting computer. I’m just curious at this point if it can be faulty ecm and or wires? Any idea? At this point I’m at a loss -
Other than the sensors, the only other thing that I have seen triggering the codes are the sensors connectors.
