On many engines with distributor less ignition systems and sequential fuel injection, a camshaft position sensor is used to keep the engine's control module informed about the relative position of the crankshaft. By monitoring cam position (which allows the control module to determine when the intake and exhaust valves are opening and closing), the control module can use the cam position sensor's input along with that from the crankshaft position sensor to determine which cylinder in the engine's firing sequence is approaching top dead center. This information is then used by the engine control module to synchronize the pulsing of sequential fuel injectors so they match the firing order of the engine. On some applications, input from the camshaft position sensor is also required for ignition timing.
The camshaft position sensor may be magnetic or Hall effect, and mounted on the timing cover over the camshaft gear, on the end of the cylinder head in an overhead cam application, or in a special housing that replaces the distributor (in the case of some of the GM applications). Operation and diagnosis is essentially the same as that for a crankshaft position sensor.  

Re  check the wire harness and the sensor installation to the camshaft sensor in Bank #1 which is where the #1 cylinder is. Good luck and hope this adds some light to you question, keep me posted and be glad to help.

2008 Chevy Silverado 2500 HD will not start


Are both batteries fully charged showing 12v? I ask this because I don't know if your friend's vehicle was charging. If it wasn't then when you put that battery back in your system it would reduce your overall voltage.

Silverado 2004 trouble


P0141 & P0161 are oxygen sensor codes, P0442 is fuel evaporative leak. P0141 & P0161 I would replace the o2 sensors, P0442, make sure the gas cap is on tight, if it is, take it off and look at the rubber seal on the cap where it seals on the filler neck. Sometimes that seal get hard/brittle and cracks. This would allow a vacuum leak in the fuel evap system. If you find cracks in the fuel cap seal just install a new gas cap. Now any time you replace parts from having the check engine light on, doesn't automaticly turn the light off. You need a scan tool for that, however, I you fixed a problen by replacing parts, the next time the computer runs its "on board" diag test & that system passes, the light will turn off. You can alway go to you local parts wherehouse or Aamco & they will scan for free.
