I had to register for this;

I have a 2002 Trailblazer LS A4WD with 190xxxx that had/has a lot of problems but through a bit of research, here & else where I was able to knock down most of my issues.

I started with
U1000 - class two serial comm. problem

P0340 - Camshaft position sensor problem

U1152- Loss at ACM/HVAC Comm.

P0013- Exhaust position actuator solenoid

P0014 - Exhaust cam postilion system performance

P1345 - CKP/CMP correlation problem

B0248 Airflow control 3 circuit short to battery

What a list, Most of these were very minor easy 'fixes' which I was able to find with a few hours of research and prep work! I believe a form of gratitude is deserved, least I can do for saving me a hundreds dollars, trips to the dealer, and for mostly all the headaches saved. :thx

I still have ONE code left which is P0340, but I found out where this CMP sensor is located through forum searching.

Upper front right, "below" the valve cover is the location?

Present Symptoms: Rough idle, Engine shakes like a misfire, Crap MPG.

Can a BAD CKP sensor cause this problem? (Just future planning, In case the CMP sensor doesn't fix my current issue)

Again Thanks for the help this forum has been able to provide!!:thumbsup::thumbsup:

just realized I posted in the wrong OEM related things for the inline 6 engines. Sorry, Mods can you move it the right place! I R NOOB
