My engine light came on about a week ago and stayed on for 4 days until the temperature outside went back up to around 65 for 2 days. Then last night after the temp. dropped below 60 the engine light came on again! What gives? My engine temperature gauge is reading normal and all my coolant and fluid levels are OK, so what could be the problem? The Jeep runs, sounds and drives like normal. After 73,000+ miles this is the first issue I'm having with my Lib. I don't have an OBD II scanner/reader and the ignition "on/off 3X trick" does not work in my Liberty, so I'm at a loss right now until I can find a shop and the time to hook a scanner up to it. I just don't want to do any unnecessary damage if it is something critical. Thanks for any answers!

Tough to know without the codes. A quick stop at most autoparts stores will get you a free check. Also Harbor Frieight has a cheap OBDII for about $40 that some of the CRD folks have purchased.

If it comes and goes it probably is some intermitant sensor in the emmissions system.

yea any local shop can help you out, and many bigger autoparts stores will have a scanner for you to use.

Thanks for the replies. I was thinking about buying a scanner with my birthday money (Oct. 23, ahem, hint, hint ). I'll keep the forum posted if I pull a code though.

ScanGaugeII is cool and I got us a $20 discount for a group buy. Still $149 though.

I just got another emissions sensor code last night but, can't find the chart to figure out which one it is.

"Bank 1 Sensor 2" Is that the Drivers side exhaust, again?

The first posting for 8/9/07 will
I think that should take you to a complete listing of all the OBD codes.
Hope you find what your looking for and it's easy to fix.

Thanks but, I've already got the codes and I know what's wrong (heated o2 sensor, again). I'm just not sure which one it is this time. I think it's the same one as last time but, it's been awhile so I can't remember for sure. Was hoping somebody knew where that diagram was that showed which o2 sensor is where.
