My 'service engine soon' light came on again after about a week. It came on after decelerating and downshifting once after an hour long highway commute and exiting via the off ramp, similar to what happened last time. This time, though, I got the ECU code after I got home, but I need a translation, please.
Code 1302: "MAP/BAR switch solenoid valve or circuit"
and the scary part, 'Have vehicle diagnosed by dealer service department or other qualified repair shop. '
What's a MAP/BAR?
Thanks for any replies.
