Most Common Reason for "Check Engine"

[Mark K 2]

I'm just putting this out there until I get around to checking it out.



What's the most likely reason for the "check engine" light to come on on a 2001 Job 2 with 68,000 miles on the clock? No noticeable change in performance or running. Initially came on during gentle acceleration. Did the remove-the-ground-cable thing to shut off the light. Came on a second time during gentle acceleration a week later.

Buy a code reader at an auto parts store. It won't cost much, and it's easy to use.

Dirty IOC, the infamous cracked elbow, DPFE sensor, etc. You need to get it scanned and post the code. Someone here will be able to tell you the problem

 

[Andy Chase]

If you're near an AutoZone they will scan for free w/ a check engine light on. Or find a local parts store that can read your codes and than post them on here.

Need to get the st scanned.

 

[Eric Gutknecht]

... and of course don't forget to check your gas cap.

I'll have to wait a couple of days until I get near an Auto Zone store. The nearest one is 20 miles away. :angry:



What does IOC stand for? It doesn't sound familiar to me.

International Oncology Convention

I would say the number one CEL cause is the DPFE sensor.

IOC = International Olympic Committee...

As Bill said, it is pointless to go around and around what it might be. Too many things to count.

I would sugest to our members to not post the question, without a code being read When the CEL light is on. No code then it becomes a guessing game..

 

[JerryW Gilliland]

Good suggestion, Eddie.



It would be like:



"Hey guys. My tire is flat, just on one side. Can anyone make a suggestion why it went flat?"

Hey guys. My tire is flat, just on one side. Can anyone make a suggestion why it went flat?

There is no air in it.

Thats funny,



I drive with all the tires flat, and the other day one of them just swelled right up on me..
