Check Engine Light
 

Greetings,

My '97 TJ (bought new) just flashed the idiot lite for
Check Engine. 69K miles. Never seen it go on before. No wrecks
in the past. Due for Inspection(less Emissions) in VA. in May.
Should I:

A. Ignore it; It'll break sooner or later and then I'll know ?

B. Ask the mechanic in May to, "take a look at it" ?

D. Don't delay, have it checked ASAP ?

Owner's Manual seems to imply emissions problem is iminent. Never
had one of these lites go off on me before. Can anyone get me up
to speed ? My TJ has always been near-cherry even after 7 years.

Andrew

I'm not sure from your post if what you mean is that it simply flashed then
went out, or has come on and is staying on. The OBD II system on your '97
takes a number of inputs and should any of them go out of spec for a given
duration it will turn on the light. If it goes back into spec the light may
go back out on its own, or could "latch" requiring you to visit a dealer to
have it turned off. The fault could be as simple as a loose gas cap, or as
serious as a failed engine component, ther Feds want you suitably alarmed
enough to take it back to a dealer for inspection, therefore they wont agree
to have it read "emissions fault" or anything less alarming than "check
engine". FWIW, the issues are rarely anything fatal.

Re: Check Engine Light
 

the same thing happened to my friend's card. he just disconnected one of the
battery poles and reconnected. the light is off since then. it sounds stupid
but it worked.. he said if there is a real problem, it will come on again..

Re: Check Engine Light
 

Yup, that works.

A loose gas cap can set the light off.

Re: Check Engine Light
 

Thx, Guys! Will try the battery trick
and check the gas cap,etc. Will report back
results.

BTW, it's really freaking me out that when I check
this thread from work via Google Groups that suddenly
my post becomes number 163(!!) in the thread "Check
Engine Light" and the original poster was a guy who'd
just bought a '97 TJ, "three weeks ago" and was having
the same problem ! Original post date was 8-10-97 !!
Weirdness on the newsgroups.

Re: Check Engine Light
 

Whenever my "check engine" light has come on around the 60k~70k mile mark,
I've found it's time to replace the O2 sensor. If the other fixes don't
help, you might try it. It's a $60 part needs to be changed about now
anyway.

FWIW, I've found that a smooth idle while warming up and otherwise
good power followd by piss poor stumbly idle is usually caused by
a "lazy" O2 sensor. Reason being the O2 sensor isn't used for warmup
just idle and cruise, and at cruise your engine is more forgiving
about the mix.

Try googleing on that subject and you find quite a few references.

Re: Check Engine Light
 

I guess you are referring to the upstream o2 sensor. Where do you find one
for $60? Most everyone where I live want $80

My 93 only has one, but yes, the downstream O2 sensor on all models to date
only monitor the catalytic converter. (least that's what the manuals say)

Got the part online.
$69 from www.chryslerpartsdirect.com and possibley www.buymopar.com
(both are dealers so the parts are OEM)

$56 from www.napaonline.com
(Sometimes you get what you pay for, dunno, claims OEM)

Re: Check Engine Light
 

Hey Guys,

For some reason this thread is all messed up. My at-home ISP
doesn't show it and the connect through Google at work still places
this thread as originating in 1997(!). All this has made it very hard
for me to follow all comments.

Anyway,... The battery cable disconnect trick worked. Check
Engine Light is out and hasn't returned in several days. Big Thanks!
for that.
