??? I couldn't pass my emisions test for my windshield sticker because I have codes: P0102, P0340, P0441. I don't know how to fix them. It's a 1997 Chevy Silverado 350 5.7L Vortec (L31).
Also said Catalyst-Not Ready. 02 sens-not ready. 02 Sens HTR-not ready. EGR Sys-not ready. I cleared the P0441 code using (OBD-2.com) VPW device but I wanna know how to really fix these. HELP PLEASE!!! <img border="0" alt="[Banging Head]" title="" src="graemlins/gr_banghead.gif" />

P 0102 maf sensor, check your fuses first, is the ses light always on? cannont clear it? P0340 had the distubutor out ? intake gasket job recently? This is the 8th vin digit R motor correct? It will not pass the readiness tests until you fix the ses light.

You should go to autozone or the like & get the troubleshooting chart for P 0340 (cam sensor not seen)& chase it down that way. If it turn the light on all the time it is a current / always present problem. There is alot to this code & the proper diagnostics lititure will point you the right way. Good luck!

I think autozone is a bunch of crab when it comes to computers. They just hooked it up to a code reader and he searched the computer for a Cam Pos Sens and he said my truck is not equiped with one and they dont have a such thing for sale. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> They dont know. The only place I found a CPSens was at carparts.com for about $25 Im gonna order one from there see how it looks like. chances are what ever it is im gonna have to change it. I still have the 02 sens problems
