Crankshaft Sensors

Where on the GM 350 Vortec engine would you find the camshaft positioning sensor?

Inside the timing chain cover there is a crank position sprocket

and a sensor that connects into the side of the timing chain cover.

There is also a sensor in the distributor(this is the camshaft

position sensor). The connector faces the firewall. To setup

your timing you have to rotate the distributor to 0 deg or you will

get a P1345 code. A timing light won't help. If you don't have the

right equipment you need to take it to the dealer or keep adjusting

the distributor until the code goes away. Jon
