HELP P1631 CODE
 
HAs anybody had this code and what fixes it, it something to do with the ignition, the check engine lights comes on but if i turn the car off it goes off and after restart it sometime doesnt come back on, i have a 95 ssei, series 1, the car has a bit of a rough idle, could this be a simple fix or big money, Thanks for all your help

Only code I could find was a 1630, no 1631 in the 95 service manual

ya maybe thats what it was, something to do with the ignition i think it sucks the check engine light stays on

1630 has something to do with the voltage being too high or too low... Above 17v or below 9v I think...

But if possible I'd have the codes pulled again.. Then erase them and see if they return..

I just checked my Alldata and there is indeed no code 1631 listed for this year.

Good luck,
