Engine Performance problem
1998 Honda Accord 4 cyl Front Wheel Drive Automatic 150, 00 miles
Are MAP & MASS sensors one in the same? I know my Honda has a MAP but does it have a MASS?
My Honda has beeen down shifting to lower gears on the freeway where and when it never use to. It acts like it has less power so it has to downshift to keep the same freeway speed on slight inclines. I thought maybe I have a bad MAP or MASS sensor. I have no codes. Dealer says everything is fine since I don't have codes. Trans oil is good to. Something has changed, I just just don't what and know body can tell me w/o code. If it weren't for the downshifting, it runs fine, no other issues.
have the same problem?
