I have an 05 Trailblazer 4.2 I6. recently my antitheft has been locking me out inconsistently for always different amounts of time. i have read alot on passlock issues and followed a similar article in how to diagnose my passlock sensor. upon doing these tests though i recieved different results and am unsure as to what they may indicate. when i tested my Red/White to Orange/Black i got 13.3v at IGN0,IGN1,&CRANK. the Yellow to Orange/Black read 4.3V in all positions. this was while the vehicle was running. when it did the no start R/W to O/B read 12.1v in all positions, and Y to O/B read 4.2. from what i understand the yellow is supposed to dorp to an unknow value upon IGN1&CRANK. not sure what it indicates, any help would be great.

4.2 I6 code P1345 and cruise control does not work... I have replaced cam pos sensor, crank pos sensor and cam pos actuator, still have code P1345. I hooked a volt meter to cam pos actuator, got12+ volt immediately at start up. Drove it 30 miles city and highway, the voltage never changed, never dropped or toggled off. Any thoughts?
I had a mechanic put a used AC compressor in my 2004 Chevy Trailblazer. He put in 4 12 oz. cans of Freon but was later told it was to much and could in fact "blow the unit" How much is the correct amount that should be put in?
