I own a Dodge Ram Van 1500 Conversion Van and my check engine light is on. I had an unusual situation happen last night. The vehicle in front of me was hauling a mattress and it fell off and I ran over it. The mattress got caught underneath my vehicle and I pulled over immediately. I was able to back up and remove the mattress from being wedged underneath my vehicle. I drove home and everything seemed fine but this morning the Check Engine Light is on. Any ideas?

 

What year is your van?

Go to the parts store, have them read codes, and see what the PCM is whining about.

 

Get the code read. The van is telling you whats wrong.

 

Ditto on getting the codes read, but my guess at this point might be the O2 sensor pigtail was unplugged or damaged.
