OBD II Problem

the code refers to the crankshaft and camshaft sensors, the crank sensor has a higher failure rate, but usually the engine will not start or run when it does. the camshaft sensor can fail and the engine will still run. I would check the connections to each sensor for damage or corrosion, the system has lost signal from one of them, if you check them with an OHM meter they should not measure open
