Kev62 Posted May 29, 2019 Report Share Posted May 29, 2019 Hi all had my car back fro a service from my local specialist. Next day a reduced power warning comes up in the RH information display. Switch the engine off and it cleared and car seems to run fine. Took the car Back to my specialist who had diagnosed the attached print from the diagnostic computer which has identified a throttle position sensor . The garage also confirmed that nothing they could of done during the service would cause this. Maybe just coincidence. Has anyone else suffered this failure on their 981. See inserted fault code below Link to comment Share on other sites More sharing options...
topradio Posted May 29, 2019 Report Share Posted May 29, 2019 The diagnostic electronics on the 981 seem a little flaky. I have had a handbrake fault warning and also a low oil warning. Both proved to be false and never came back. If it has gone away I would wait to see if it returns before spending any money. Link to comment Share on other sites More sharing options...
Kev62 Posted May 29, 2019 Author Report Share Posted May 29, 2019 Hi thanks for your reply. Guess it’s just a case of wait and see and keep fingers crossed. Link to comment Share on other sites More sharing options...
Paul P Posted May 29, 2019 Report Share Posted May 29, 2019 Get them to clear the fault and run the suggested diagnostic steps to see if it comes back. Link to comment Share on other sites More sharing options...
Kev62 Posted May 30, 2019 Author Report Share Posted May 30, 2019 Hi Thsnks for your help. Not sure about requiring a reset of the fault code as when you turn the ignition off then restart it seems to clear the warning which then only returns at random.

But not the one logged in the DME. That’s there until it’s reset. I was suggesting they clear the code, do the diagnostic steps listed and see if it returns. If it doesn’t occur when Diags are run then if it does come back later then you know you are looking at a new instance of the fault not an old one.

Kev62 Posted June 1, 2019 Author Report Share Posted June 1, 2019 Hi Paul Thanks for your advice. I have had the fault code reset the dealer also tested the accelerator potentiometer and it all checked out ok. Just using the car as normal now to see if the fault re occurs. Looking around the forums this fault was common in the 987 but has not been an issue as yet on the 981. Fingers crossed it does not come back.

Jason986S Posted June 1, 2019 Report Share Posted June 1, 2019 I certainly wouldn’t go chucking parts at it after a single code/warning. Punch of salt comes to mind with these kind of things. Coulda been a bit of dirt on the sensor or just a funny 5 mins. A reset and test over time will likely prove nothing is wrong. Link to comment Share on other sites More sharing options...
Kev62 Posted June 2, 2019 Author Report Share Posted June 2, 2019 Well fellas pleased to report a 160 mile round trip to Simply Porsche at Beaulieu today and Porky run great with no repeat of this fault. 👍👍 Link to comment Share on other sites More sharing options...
Kev62 Posted June 6, 2019 Author Report Share Posted June 6, 2019 Hi Fellas latest update is that after a couple hundred miles the fault has not returned. However the dad does seem to have a very almost unnoticeable hesitation just as it changes up a gear. Can’t say it’s definite but just seems slightly more jerky than before the service. Will keep monitoring and post any updates. Link to comment Share on other sites More sharing options...
Kev62 Posted October 4, 2019 Author Report Share Posted October 4, 2019 Latest update on this is that the warning comes up occasionally. Seems to happen if the car is jolted by hitting a pothole or if you drop something heavy in the boot. Just monitoring for now as the fault seems to clear if you stop and re start.

Menoporsche Posted October 5, 2019 Report Share Posted October 5, 2019 You make it sound like an electrical plug or some other connector is loose. Would also make sense that it first happened just after a service. Link to comment Share on other sites More sharing options...
Greenman Posted October 5, 2019 Report Share Posted October 5, 2019 Yeh it sounds a bit like a loose plug or a none sound connection somewhere doesn’t it, either that or you just aren’t using the accelerator enough😉 Link to comment Share on other sites More sharing options...
