Hi, I would like to know why does my 1995 Dodge Caravan check engine light come on and stay on when I go on the highway until you turn the engine off but around town it does not come on? I went to the auto store and they told me that they can only check the "Check engine light" on 96' and up models.

Thanks, N8

Try having the vaccuum checked to the egr valve. At wide open throttle (on the freeway) vaccuum will be applied and the valve should open. It that is not happening, the light will come on. The egr valve rarely opens during city driving. good luck!

Suggested Repair

Have the vehicle scanned with an OBD1 scanner. Also check vacuum to the EGR valve: at highway or wide-open throttle, vacuum should open the valve, and failure to open can turn on the check engine light.

Conversation Summary

The owner of a 1995 Dodge Caravan said the check engine light comes on and stays on during highway driving until the engine is shut off, but not during city driving. A parts store said it could only scan 1996 and newer vehicles. Replies suggested an OBD1 scan and checking vacuum to the EGR valve, which is applied at wide-open throttle on the freeway and rarely during city driving.
