2002 trailblazer 4.2 4wd i have a code p1345 that keeps returning ive replaced the cam postion sensor and the crank sensor and the cam postion actuator solenoid i just put the cam position actuator solenoid in about 1000 miles ago and the code came back so it lasted for a 1000 miles ray
In many cases, this code is usually caused by simple electrical connection failure or a failed camshaft sensor. ... If there has been a misfire or failed sensor, then an additional code will come with P1345.
Dammed electronics ,bane of my life so your not the only one and in cases like this i can only suggest you bite the bullet and take vehicle to a main dealer .sorry i know this isnt the answer your looking for but from experiance certain things on modern motors you cannot do your self

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.
