P0340 Camshaft Position Sensor Malfunction

Question

I have a P0340 CPS Malfunction code on my 2003 Kia Rio. I have replaced the ECM, both the Camshaft and the Crankshaft sensors, checked the ground connections, ohms for both sensors, checked continuity to include the wiring harness as well as looked for any damage in the wiring harness which I found none. All visual checks and readings are within specs but this single code continues to come back immediately after clearing it. I need help, I'm at a lost on this one.

Hi there,

Check the timing belt. It's quite possible the timing has jumped a couple of teeth and that will give you the cam sensor code.
