2004 Dodge Ram 1500 4.7L Engine P0344 Cam Sensor & P0302 Cylinder 2 Misfire Issue

Model: 2004 Ram 1500 Fault Code: P0302 Posted: 2014-02-03 15:52

I'm experiencing two diagnostic trouble codes on my 2004 Dodge Ram 1500 with a 4.7L engine: P0344 (Interruption in camshaft position sensor circuit) and P0302 (cylinder 2 misfire). I've already replaced both the camshaft and crankshaft sensors, but the codes persist. Despite these replacements, the vehicle continues to exhibit rough idle and performance issues. I'm seeking input from other owners of this model, especially those who have encountered similar problems with the 4.7L engine. Any insights into potential causes—such as wiring connections, sensor quality (OEM vs aftermarket), or related components like the throttle position sensor (TPS)—would be greatly appreciated. Thank you for any advice or experiences shared.

Check the wiring harness and connectors for the camshaft sensor circuit—intermittent faults often stem from poor connections, even after replacing sensors. The P0344 code specifically indicates an intermittent signal in the circuit; inspecting the physical wiring and grounding points is a critical first step.

I replaced the aftermarket camshaft and crankshaft sensors with OEM units, changed spark plugs and ignition coil for cylinder #2. Both P0344 and P0-302 cleared immediately. However, the engine now runs roughly and has triggered a new code: P0300 (multiple cylinder misfire). This suggests that while sensor quality may play a role, underlying issues like fuel delivery or ignition system health remain unresolved. I'm currently testing with OEM sensors to see if this resolves the problem long-term.

I've heard that replacing the Throttle Position Sensor (TPS) can resolve misfire codes in some 2004 Dodge Ram 1500 models. While it's not a direct fix for P0302 or P0344, faulty TPS signals may affect engine timing and fuel mapping, potentially contributing to misfires. I'm considering this as a potential next step—any verified experiences with TPS replacement in this vehicle?
