What is code p1345

The P1345 means SGC (Cam Position) sensor circuit malfunction/crankshaft position-camshaft position correlation
P0300 means random/multiple cylinder misfire detected

mpps ecu chips

its not just the camshaft position sensor the code is fault with either -----crankshaft position sensor with camshaft position correlation
P1345 Chevrolet Crankshaft Position Camshaft Position Correlation P1345 Yahoo Video Search Results

po134 is o2 sensor bank 1 sensor 1
po161 another o2 sensor
p1345 crankshaft position sensor
possible cause for o2 are vehicle control module (PCM) or wiring

Fault code..P1345 Crankshaft Position (CKP)..Camshaft Position..V. Check to see that both are hooked up and working properly.

p1345 is a crank/cam sensor correlation fault possibly due to a
failure in this solenoid.other possible causes include engine timing

beleive it or not changing the oil if dirty will solve this code, also found that connector gets oil in it and that also makes p1345 code turn on, open connector and look for oil in it,look at sensor and actuator plugs for oil,the main plug connector is the actuator plug it fills with oil and makes contact between pins setting p1345 code, hope this helps.

Most likely the timing has jumped,or the cam sensor is bad.

i have done this before on these --- the distributer is off 1 tooth.when you pulled out the distributer some times the slot that runs the oil pump moves.so when the distributer go back in it finds the slot but it will be off 1 tooth.
