ACES70 Posted January 15, 2007 Report Share Posted January 15, 2007 I recently got a check engine light. Its P1550 "manufacturer controlled speed metering" or something close to that. Any ideas as to what might casue this? I just got some new rims and tires and I was thinking that maybe the larger size would throw off the speedometer. Could this be the case or is it something else? Link to comment Share on other sites More sharing options...

Could this be the case or is it something else? lol that would more then likely be the speed sensor on the transmission , if you change tires the car has no way of knowing , if I remeber correct you speed is told to you off the revolutions on the transmission and more then likley that sensor , its on the top of the transmission and is pretty easy to change , not 100% sure of location although Link to comment Share on other sites More sharing options...

garbergtsi Posted January 15, 2007 Report Share Posted January 15, 2007 vehicle speed is aquired through the ABS module by averaging the front 2 wheel speeds, then sent to the network to the ECM, instrument cluster, ect Link to comment Share on other sites More sharing options...

garbergtsi Posted January 16, 2007 Report Share Posted January 16, 2007 basically the code means the ABS module either lost communication or there is a fault in either front WSS's.You need to get a scantool to access the ABS to really diagnose it.or just guess and say its the ABS module like everyone else does Link to comment Share on other sites More sharing options...

Piglet Posted January 16, 2007 Report Share Posted January 16, 2007 Make sure your speed sensors are seated right. If you put on new wheels there's the possibility you could've hit the wire to a sensor. There's nothing like having your speedo cut out while driving home and having to drive past a police station Link to comment Share on other sites More sharing options...
