Hi guys......need some help here..!!!!

Was having trouble starting my 99 LS1, scanned and found the 0342 code. Cleared the code and the start returned to normal, for about a day, then came back with the same starting issue. Cleared again and start was normal. It continues to return as described. I have checked the connector to sensor and all looks well. Is this likely the sensor, PCM or wiring issue..?? Not looking forward to pulling intake to swap sensor if i dont have to..!!! What are your thoughts.??


Thanx in advance for your suggestions..!!! DK

 

ttt.....nobody..?

 

Did ever find out the problem? I have a 99 silverado with 5.3 and it is doing the same thing. I replaced the cam sensor and does the same thing maybe wiring harness or pcm? Please help!

 

I too am having this problem, i have traced all 3 wires and looked for a break. no problems there. replace sensor and the harness plug. still no tach and p0342 code.

I have heard of cam retaining plate bolts coming loose and letting the cam walk foward.

When i originally did my cam swap 1 of the stock plate bolts was loose. after the cam install i lock tighted them. thats the only option that is left for me. take it for what its worth. im gonna have to tear the front of the motor down i guess

 

anyone ever find out what was wrong?
