Hi andybean,

Thank you for the donation.

Erase the trouble codes, test drive vehicle and retrieve the trouble codes again. Let me know if they are the same and in which order.

P0340 = Camshaft position sensor malfunction.

P1312 = Combustion detection cylinder 1+2 , open/short circuit to B+.

P1334 = Combustion detection cylinder 3+4 , open/short circuit to B+.

The camshaft position sensor is the more likely cause.

cam sensor is built into the direct ignition cassette [di] the module that sits ontop of the spark plugs ,u need to replace the di ,just an addition to khlow2008 ,good help out khlow2008.
