Have you checked the car for trouble codes after you changed the belt? If not recheck them. Did you change the Camshaft Position Sensor? P0341 P0341 - Camshaft Position Sensor 'A' Circuit Range/Performance PDF Share Code P0341 Comments | Add Comment Possible causes - Faulty Camshaft Position Sensor - Camshaft Position Sensor harness is open or shorted - Camshaft Position Sensor circuit poor electrical connection - Faulty starter motor - Starting system circuit - Dead (Weak) battery What does this mean? What does this mean? Tech notes Sometimes and in some models, low battery voltage or a weak starter can can trigger a Camshaft Position Sensor code. What does this mean? What does this mean? When is the code detected? The camshaft position sensor signal sent to the Engine Control Module(ECM) during the first few seconds of engine cranking is out of range. Possible symptoms - Engine Light ON (or Service Engine Soon Warning Light) - Possible lack/loss of power - Engine may stall while driving P0341 Description The Camshaft Position Sensor is an electronic device used in an engine to record the rate at which the camshaft is spinning. This information is used by the Engine Control Module(ECM) to control ignition and fuel injection. The camshaft position sensor senses the retraction of camshaft (intake) to identify a particular cylinder. The camshaft position sensor senses the piston position. The sensor system consists of a rotating part, typically a disc, as well as a static part, the actual sensor. When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change. The changing gap causes the magnetic field near the sensor to change. The change in the magnetic field cause the voltage from the sensor to change. When the crankshaft position sensor (POS) system becomes inoperative, the camshaft position sensor provides various controls of engine parts instead, utilizing timing of cylinder identification signals.

Old oil causes the cam chain to wear quickly. As a result, it stretches beyond the point where the cam chain auto-tensioner can keep up. That extra chain slack causes the valve timing control (VTC) actuator and the exhaust camshaft sprocket to lag behind, and you wind up with DTC P0341.

With no compression on any of the cylinders either the valve timing is not set properly or the valves are damaged. If this is an interference engine, which means that the pistons will slam into the valves as they open if the timing chain jumps or fails causing the engine to stall, the valves are bent and not seating. This will cause no compression. To have compression all valves on each cylinder must be closed at the proper time during the piston's travel. This is not going to be a sensor issue. It's a mechanical one. Double check the timing marks. You may be 180° out. Since it ran before you did the timing chain the valves were not damaged at that point. But they could be now. You'll have to be 100% sure that the timing marks are in the proper position. Even cranking over an interference engine with the valve timing 180° out will damage the valves. HTH. -Jim
