P0341 - Camshaft Position Sensor Circuit Range/PerformanceThe engine camshaft rotation is synchronised with the crankshaft. The engine computer (ECM) constantly receives the signal from the crankshaft position sensor (CKP) that is compared to the signal from the camshaft position sensor (CMP). The trouble code P0341 is set when the camshaft position sensor (CMP) signal is out of expected range or if it is not timed properly with the crankshaft position sensor (CKP) signal. Show What can cause the code P0341: Examples: A service bulletin for the 2003 V6 Jaguar models mentions checking the resistance of the spark plug and replacing the spark plug along with the coil if the spark plug's resistance is too low. A technical service bulletin (TSB) for late 90's Saturn vehicles describes a problem where incorrect resistance in the ignition wires and secondary ignition system can cause the DTC P0341. A Chrysler TSB for 2010 Ram pickup trucks equipped with a Cummins diesel engine recommends re-flashing the ECM for the P0341 and some other trouble codes. In some 4-cylinder 2003-2010 Honda Accord, Civic, CR-V and Element engines, a stretched timing chain can cause the Check Engine light (MIL) to come on with code P0341. What needs to be checked: How the camshaft position sensor works: A CMP sensor could be a two-wire pick-up coil type or three-wire Hall effect sensor. A pick-up coil sensor generates an electric signal, while the Hall effect camshaft sensor needs a 5V reference voltage. Modern OBDII cars mostly use a three-wire Hall effect camshaft position sensors. The engine computer (ECM) uses the signal from the camshaft position sensor to know which cylinder is in the compression stroke, as well as to control the ignition timing, fuel injection and the variable valve timing system (if equipped). Q: 2001 1.8L Volkswagen Passat turbo. Some gaskets and seals and the timing belt has been replaced, but now I got the code P0341 and the engine is hard to start. What could be the problem? A: Double check the timing between the crankshaft and the driven camshaft at the timing belt, as well as the timing between two camshafts, as the chain that runs between the camshafts can easily jump a tooth and this will be enough to set the P0341 code. Q: 1999 Chevrolet Malibu 3.1L V6 misfires and runs poorly. The parts store scanned the computer and there was a code P0341. Is it an expensive to repair problem? Where do I start? A: Starting with a tune-up will be a good idea; as mentioned above, in these GM V6 engines the high resistance in the ignition components can cause arcing that could in turn cause the electrical interference with the camshaft sensor signal. If the spark plugs and wires haven't been replaced for a long time, this could easily cause this code. Check the sensor's wiring and the connector for corrosion or loose connection. Also, it's worth to check the ground cable connection as this also can cause electrical problems. What is a camshaft position sensor A circuit Bank 1?The Camshaft Position Sensor is one of many sensors. It relays valuable information that the vehicle's primary computer or powertrain control module (PCM) uses to calculate fuel injection and ignition timing. When the PCM detects that the signal from this sensor is intermittent or missing, the P0344 code gets set.
What could cause a P0341 code?What Does the P0341 Code Mean? Diagnostic trouble code P0341 stands for “Camshaft Position Sensor “A” Circuit Range/Performance (Bank 1 or Single Sensor).” It is triggered when the powertrain control module (PCM) detects a problem with the signal being sent by the camshaft position sensor.
