Chevy 2.2 Timing chain

I was wondering how this worked out. My son's truck is having similar problems and was hoping for advice. I'm thinking that it might have jumped time.. I've had people tell me that it might have jumped time but also had someone tell us that it hasn't. I'm pretty frustrated at this point. He was driving and it quit. The engine is turning but not firing (recently had a friend check and the spark plugs are getting fire). It's giving off these codes: P0141 O2 sensor heater circuit fault (bank 1, sensor 2). P0300 cylinder misfire detected (random). P0342 camshaft position sensor circuit, low voltage. We know that it's not fuel pump, O2 sensor, plugs/plug wires, camshaft position sensor, crankshaft sensor, coil, fuses, or relay. I know that it could be so many other things as well. I was hoping for some input because I really don't want to go through all of the trouble and it turns out that isn't the problem. Could a fuel injector cause this? Is there a way to find out if the timing chain is a problem without tearing down to visually see it? Any and all advice is very welcomed. -- for full context, visit https://www.motorsforum.com/gm/ecm-t...rix-78057-.htm |

The P0141 is irrelevant to your problem but you maybe should fix it later. The P0300 is a vague symptom of the problem. The P0342 tells you something useful. If you have a proper scanner you should be able to look at the ignition timing as well as look at the camshaft position sensor waveform. If the sensor isn't bad, likely the cabling to it is bad. That cabling includes the engine block ground, incidentally. But looking at the waveform will tell you a whole lot more than just looking at error codes. --scott -- "C'est un Nagra.
