Dodge truck codes?

Try key on, off, on off and on again your digital odometer will tell you the codes, if you do not have a digital odometer, you can count the number of times the check engine light flashes, the codes are three digits.

Also most consumer auto parts stores (Autozone, etc.) will 'loan' you a scan tool (or scan it themselves) for free.

Thanks a lot. I'll give it a try and see what happens.

OK, I tried the on-off sequence and the digital odometer only read the mileage. When I turned the engine back on, the check engine light was out and it hasn't come back on. Must have been some sort of transient? I'll keep watching for it to reappear. Thanks for the help.

Probably was transient. Perhaps a loose gas cap, or evap leak that isn't consistent.

BTW, the key on/off bit is a bit touchy, when I used to do it (before I got a good scan tool) I'd sometimes have to try several times before it worked.
