Front speed sensor
 

Good morning, as some of you may know, my 986 is having some issues. Changed my tip atf fluid and it went forward and reverse (very slow still), finally got my durametric and checked faults... the ole girl only had two they were both connected to the abs and psm/tc errors.

Front right speed sensor
Front left speed sensor
And
4607 control module faulty

Does anyone think this is causing the ecu/tcu to think the car is going much faster so it revs higher but doesn't go righ?

If anything I'd think it's telling the car it's standing still or there's a difference between fronts and rears.

Thanks, makes sense, do you think this would cause high revs with little forward movement?

Sorry, I may have missed your earlier posts - was the transmission working fine before the fluid change?

No, as far as I know the p.o had it inspected and okayed for road worthiness in July. But when I got it it only reversed. It seems fine in reverse, but I've only driven manual 986, 996 & 944s so not much experience with tiptronic (aside from cayenne's) so idk how fast you can go in reverse with these cars.
