tbh...not tried doing this on fords as have the equipment to clear codes which will be enough to get out of limp...i know it works on some makes but have never tried as dont need to..

you wont do any harm by trying though...unless you dont have a code for radio if necessary

 

sure the TPS is available from other sources, not just ford..but beware of cheap copies, cause more grief than they're worth.

 

wiring issues arent uncommon in that area so well worth checking that first before handing out £££ss

should know that disconnecting will mean ecu needs to relearn after so may have few other minor glitches for a few miles of driving..nothing that will cause any major problem though...still recommend you check that wiring first too

Disconnected battery ..it worked ..faults cleared ...200 yards down road ...limp mode again fault P2176. So carried onto my local garage and left it with them...it's beaten me!!! Had enough!! I'm taking bets on what sensor packs in next if anyone fancies a flutter....have no faith that this will be end of the problems. Going to write to Ford to tell them what I think of this joke of a vehicle I and many others have been lumbered with. How this hasn't been a recall is a joke....too many having exactly the same problems is not just a coincidence .

looks like it is the TPS, suspect it will have a new throttle pedal assembly installed so that this rectifies the issue.

Took car to garage they can't find TPS to change are you saying it's not that but the actual pedal/accelerator that's causing problem .

Garage rang pedal assembly ok they reckon it's TPS as you first said ...looking for correct part as one they were sent won't fit or something . Too small? Left it with them but looks like another big bill on its way!

I was under the impression that the TPS is built into the pedal assembly...

I'm not mechanically minded James but I thought throttle position sensor was on actual throttle body ...if I'm wrong fair enough but can't find any pics of exact location on my car. Garage says he checked pedal assembly so surely he must have noticed if it was there ? Any ideas or pics would assist .

depending on type. either

early type..3 pin sensor on throttle body

late type

TPS is part of the throttle control motor which is also on the throttle body

Hi Paul,

 

I can always be wrong! I have conversations with a few different people and different motors, it wouldn't surprise me if I have the wrong thing in mind (think its a french 'thing' I was talking to a colleague about earlier!)

No worries James you've been great source of info. Received some photos regards sensor and it's actually behind plate which is fixed to throttle body so the lad in garage is on right track ...thank god! Hopefully will be back on road soon... Frustrating thing is I really enjoy driving the car it's comfortable and smooth drive ...when running correctly... Just hate not having my wheels ....thanks for your input ...

Ok - after being messed around by the first ebay seller, my code reader arrived yesterday and I've just been out to the car to take a look. I'm using the 'Torque (Free)' app and I checked the logged faults, pending faults, historic faults. There is one pending fault code of U0073 - does anyone know what this is please?

 

Apparently the garage I usually use doesn't have a diagnostics machine, so I guess I'd need to call up with the suspected issue and ask if he can take a look, or find a different garage (the thought of which makes me nervous!)

U0073

control module : data bus off

 

hints at loss of power at engine control module....for now, iwouldnt worry about it, clear the code and see what happens from then.

 

though might be worth having the battery/charging checked, any problem there may be enough to flag it up, maybe at some point the voltage dropped below what was required
