I have a 1999 2.4L Caravan. The Service Engine Soon light recently illuminated and the vehicle began running a little rough. The last time I had this problem I just did plugs and wires, and the problem was solved. I just did the same thing with no good results. It has almost 190k on it, so Im not going to crazy over it. I have never had any issues with this vehicle. Any ideas from anyone would be a big help. Thanks.

 

What code is turning on the SES light? Autozone or the like will scan codes for free.

 

What were the codes you were getting?

 

Went to Auto Zone, got a code P0405,which showed the EGR system. I picked up a new EGR. Before taking the valve out I saw that the small section of vacuum hose that attaches from the transducer to the valve was almost broken in 2. Figured I install it anyway. Started the van up....runs much better, but should the Service Engine Lght out,or does it take a while?...Thanks

 

It will stay on until the computer realizes the problem has been corrected. You can clear it early with a scan tool or by disconnecting the battery for a while.

 

Disconnected the Neg lead on battery and re connected it about 20 mins later. Went for a drive and the light stayed of and it is running much smoother. I probably coild have just spliced in a small section of vacuum hose, but after 186k I can't complain. To remove the one bolt from the pipe that connects into the EGR was a pain. An offset 10mm wrench would have come in handy and to remove the solenoid connector, the plug has a red clip that needs to be pushed back so the plug can unsnap. Thought I share this in case someone else needs to do the same.
