SteveW Posted July 9, 2016 Share Posted July 9, 2016 Hi Everybody, I have an issue, my ESP occasionally activates on right hand turns if going over 40mph. Long right turns tend to trigger it the most. I've done the pedal dance and have no fault codes yet I keep getting this issue. I'm running 245/35/19 front & 275/35/19 rears and been in this set up for about 5 years without issue. Had a bit of a Google and found one reference to the Yaw sensor but post sounded a bit flaky so thought I'd ask here. Thoughts? Thanks Steve Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted July 9, 2016 Share Posted July 9, 2016 It could well be the yaw sensor playing up, it senses the gyroscopic movement from the axis the car is moving on, so the slip control is only operating because of a spurious sensor reading.

Richie94gts Posted July 9, 2016 Share Posted July 9, 2016 Presumably you have a stock steering wheel? i had something similar after I changed the steering wheel and the little "nipple" sensor thing wasn't in the correct position. It seemed to confuse the car into thinking I was going sideways everywhere! Quote Link to comment Share on other sites More sharing options...
SteveW Posted July 9, 2016 Author Share Posted July 9, 2016 Yes standard steering wheel, nothing has been changed from the set up when this wasn't happening six weeks ago. At first I thought I must have a goosed wheel bearing but all are rock solid. Quote Link to comment Share on other sites More sharing options...
SteveW Posted July 14, 2016 Author Share Posted July 14, 2016 The fault is so random, nothing for two days then 40mph round a long, shallow, & dry right hander ESP kicks. Nearly took me into the kerb!!!! Quote Link to comment Share on other sites More sharing options...
R35LEE Posted July 16, 2016 Share Posted July 16, 2016 I doubt it's the yaw sensor, but a fair few things it could be. Where are you based Steve and has anyone plugged into it yet for any stored fault codes etc? Sent from my D6603 using Tapatalk Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted July 16, 2016 Share Posted July 16, 2016 The only other things that can influence the Trac control part of the ECU is the ABS/speed sensors, but they usually either work or don't. Quote Link to comment Share on other sites More sharing options...

It's not been plugged in to anything. I think a mate has a cheap ODB2 system. Will have to check. I guess these are codes that wouldn't show up with a pedal dance due to going inactive immediately after triggering?

Thanks mate, that's what I thought too but like you say that either works or doesn't usually and there don't seem to be any issues there-well at least I don't think there are.
