My pops has a 2001 XJ and his Check Engine Light just came on. He got online and found out how to check for codes, and said that it wasn't giving him any error codes. He then disconnected the battery, re-connected the battery and so far it has stayed off. Any ideas what might be causing it to come on?

 

Next time you get a CEL take it to your local parts store (napa) they will be able to look up the code for you and tell you what it is. When we can tell you what to make of the code.

I had the light on a couple months ago on my 01 too. It was the misfire in cylinder #3, which is common. I cleared the code and it never came back on. It happened while i was 4wheeling. Moisture in the injector or something like that...nothing big.

 

Might be a hi-jack but will OBD II readers read OBD I as well?

 

Thanks guys. He cleared the code by disconnecting the battery. If it comes back on I'll tell him to take it in and get it checked on the OBDII.

 

Check the gas cap. My wifes Malibu does that if it is not on tight enough and it doesn't throw a code. My dad's Caravan did the same thing.

 

Got it. Will do.

 

My wife's monte carlo does the same thing, I click it 20 times and the light won't come on.

 

Chryslers don't need a obd-I reader.. Key on/off three times...

But to answer your entire question.. maybe... Depends on whether you can match the plug or not. The different manufacturers all had differing plugs on their OBD-I plugs. With a GM you could actually short two pins in the connector and not even need a reader.

 

The only thing I have new enough that it has an OBD anything is a '96 Chevy Pick up and a '97 Mazda. Can I buy a OBD reader that will work for both?

Both are OBD-II. ODB-II came into use for the '96 model year. So yes a single scanner will work for both. The HF one linked earlier would do the job.

I have an older Actron scan tool... works great. But they don't offer this model anymore.

 

Some scan tools just give a number that you have to look up. Others give you a description of the problem. Which type is the HF one, if you know?

 

I don't know... I have an Actron......

 

Thanks. Going to go check on the HF one tomorrow. Got a check airbag light on my Mazda.
Jap junk I guess!
