#6 of 65 "New" '95 Blazer with some problems - codes by rubisco Apr 23, 2007 (12:30 pm)
Hey All, my first post here!   So I have 2 '95 Blazers. My old one I've had for eons and although it's had some of the regular problems I like it very much. So I pick up another and it's throwing some codes but running good. They are P0326, P0441 and P1406. Now I know that 0326 is knock sensor performance and 0441 is no flow during evap purge cycle, but I'm not sure what 1406 is for. It's not in my haynes manual and I can't find much on the web for it. Some have said it's a bank 1 post cat O2 sensor thing.   Ok, I was changing the cap and rotor and noticed that some knuckle head broke off the rear stay for the dist cap screws. So I have 2 wood clamps on there. Could this set off the knock sensor? Or do these just go bad and need replacing? I'm not sure where it is if it needs replacing.   I don't know much about how the evap system works, but I heard there is a valve somewhere that can be replaced and also a canister. Otherwise this smoke test a shop can do. I just don't know where the valve and canister are located. Any ideas?   The 1406 code?   I guess I should add that the EGR valve was getting all gunked up with carbon pellets so I took the plenum off and cleaned it up real good and thoroughly cleaned the passages to and from the EGR. Then I put on a filtered gasket to stop any more pellets from getting stuck. I read somewhere that it could be that the IAC needs a cleaning too (?). I've run a bottle of seafoam through the tank and the intake and it idles very very smooth now. Replies to this message: repairdog (Apr 24, 2007 2:21 am) gorbey (Sep 09, 2008 8:19 am)

Replying to: rubisco (Apr 23, 2007 12:30 pm) 1406 is EGR. That evap can is rear drivers side way back behind the rear wheel under that shield. Replies to this message: gorbey (Sep 09, 2008 8:19 am)

Replying to: repairdog (Mar 03, 2007 6:00 pm) Thanks very much man. I'll take a good look at both of those and post if I still have a problem. You seem like an extremely knowledgable guy. Thanks again.
#9 of 65 2003 Chevy Blazer by sgnobod2000 Jun 23, 2007 (6:10 pm)
I just recently got my service engine soon light coming on. I thought originally it was bad gas because it was right after I got gas, within 15 minutes. After my store stop I added the same amount of gas from a different station. Light stays on. runs ok. Is there a manual way to get the codes on this vehicle or do I need a reader. I know my other vehicles you had to do a succession of key off etc. I would appreciate any help. Replies to this message: repairdog (Jun 24, 2007 3:32 am)

Replying to: sgnobod2000 (Jun 23, 2007 6:10 pm) No, need a code reader and Advance and AutoZone read for free as well as many other local stores (in hopes of selling you parts). Read it out and maybe just a simple loose cap so write the code down and have them erase it and see if it returns.

Replying to: mitch16 (Sep 24, 2007 4:25 am) P0141  O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)    Probably in exhaust pipe just behind the converter.

#15 of 65 Chevy Blazer error code by bptbd Nov 11, 2007 (2:42 pm)
Replying to: jlflemmons (Sep 26, 2007 10:40 am) I am working on a 2000 chevy Blazer and the error code that came up was P0147. It says that it is an oxygen sensor. Does anyone know what (out of 3) oxygen sensor this may be? Thank you in advance.
