Engine/Transmission (1998.5 - 2002) Trouble Code P 1790

[Blue Thunder]

Recently my check engine light came on and displayed the code: P 1790. This hasn't been the first time the light has come on, but usually it resets itself after a day or so. This time it has stayed on for about three days and several start ups. Please help if you know what this code means.

You can find the specific code at this site: www.obdii.com/dtcanatomy.html . It looks like a transmiision code.

The proper form is one letter followed by four numbers without any spaces. Your code is P1790.

re: referal

Tried that website, with no result. Yes, it does seem to be the transmission, however truck is running 'normal'. Perhaps one of the transmission gurus out there might be able to shed some light.

I looked through my 02 books and cant find that code but I think its a trans code too.
