Not to mention fixing the horn, e-brake, and a bunch of other little things, followed by a good cleaning. The car failed; /html/shop-talk/2005-09/msg00019.html (7,856 bytes)

Replacing that, and making sure the engine was good and hot before testing, got me to pass. It's entirely possible the O2 sensor was; /html/shop-talk/2005-09/msg00020.html (8,421 bytes)

A bad O2 sensor would probably have fired the MIL ("Check Engine") idiot light. A tuneup (plugs, wires, rotor, cap, PCV) wouldn't hurt.

I believe 96 was the year compliance with OBD II was mandatory. Some vehicles had it prior to that. Run the heck out of it prior to taking it int; /html/shop-talk/2005-09/msg00022.html (9,260 bytes)

Cats are only good for 50k miles or 100k miles (depending on the year, I think the change was in 1996 also) Oxygen sensor could be an issue, but as I recall, excess hydro-carbons; /html/shop-talk/2005-09/msg00023.html (9,321 bytes)

RE: Questions on Emissions (score: 1): Author: "Randall" <tr3driver@comcast.net>; Date: Fri, 9 Sep 2005 07:10:27 -0700; HOx isn't one of the tests, it must have been either NOx (nitrogen oxides) or HC (hydrocarbons). A NOx failure indicates the EGR valve isn't working (bad valve, plugged passages, broken/cracked vacu; /html/shop-talk/2005-09/msg00024.html (8,371 bytes)

O2) without a code reader/scanner, but since the MIL isn't lit (I presume) it won't tell you much in this case. bs ** Bob Spidell San Jose, CA bspidell@comca; /html/shop-talk/2005-09/msg00025.html (10,047 bytes)

Re: Questions on Emissions (score: 1): Author: John Miller <jem@milleredp.com>; Date: Fri, 09 Sep 2005 07:25:21 -0700; NOx typically means high combustion temp/lean mixture/exhaust leak upstream of the converter, IIRC. O2 sensor, maybe. Plugged EGR valve or passage. Got the manifold crack fixed and the fixed manifol; /html/shop-talk/2005-09/msg00026.html (7,938 bytes)

I assumed he meant hydrocarbons since the California test only allows about 400ppm NOx. My SO's Country failed smog due to NOx, I put a new cat on (per the tester's recommendation) only; /html/shop-talk/2005-09/msg00027.html (9,626 bytes)

Hoerning" <hoerni@cooper.edu>; Date: Fri, 9 Sep 2005 10:53:19 -0400 (EDT); I don't know about jeeps, but I do know for a chevy TPI system it won't light the light. O2 sensor readings are what it considers soft conditions. It only lights the light for hard conditions (althou; /html/shop-talk/2005-09/msg00028.html (8,486 bytes)

Cycling the ignition switch on/off 3 times will cause the check engine light to blink out the error codes.
