guys, for the past few, my 2005 gt has gone into failsafe mode. I turn the car off, wait abit and then the car runs fine for a while, week month etc. then out of nowhere, it will go into again then I turn car off, and it works fine again. I have a steeda CAI with sCT programmer and the codes are the same ones that come with the TSB for this that is posted. this has been reoccuring more frequently. I took it to dealer and they want almost 500 for the part and install of this TPS sensor and then a re cal of my computer. does this sound right?

is the install something I can do myself? if so, what part no would I need and where can I get the part. is there a write up somewhere on this. Sorry tried searching and couldnt find what I was looking for

Thanks

Sam

I had this same issue and I actually just decided to replace the whole throttle body and haven't had any issues since. You might try just cleaning the throttle body and seeing if that fixes your issue as several people have said this is the fix. Its also the cheapest to try. I believe the guys over at Brenspeed posted a video here about cleaning them.

If all else fails you can buy the TPS (part 6L2Z9B989C) at Bob Utter Ford Parts http://www.trademotion.com/partlocat...?siteid=213787 for $65 bucks. I believe there are only 2 screws holding it on.

A guy on another forum just replaced the TPS himself and still had the issue until he completely cleaned the throttle body. I think that may be why buying a new throttle body also works. They are $180 or something at newtakeoff.com http://www.newtakeoff.com/mustang_gt...ludes_tps.aspx

Goodluck.

thanks do you know if there is any re calibration or anything like that if you replace that part or is it a simple replacement and you are done?

Thanks for the intel

Sam

also, what the heck do you think the reason is behind them charging like 450 for this work? the part is 65 and it takes worse case 1 hr to put it on, double check it etc. wouldnt 100-150 seem like a reasonable price to do this?

You're at their mercy if you take it to the dealer.

You should just do it yourself--the TPS is VERY easy to access, and only a couple screws to remove/replace. They've failed on a few friend's S197s as well, seems to be relatively common.

thanks guys, do you know though if the computer has to be recalibrated or anything, is there a write up or instruction guide to replacing this?

A simple TPS replacement worked for me !

Be very careful and follow the instructions on the TPS mounting bolts removal !
I believe you use an electric drill so as not to break them. They`re really small and Ford uses lock tight which doesn`t allow you to back them out by hand.

I know, I tried it !

sams66

thanks for that I-70 it is exactly what is happening to mine. when you purchase the TPS does it come with instructions? when you replaced it, did you have to retune or recalibrate anything? is it a simple thing like bascially unscrewing the old one and putting the new one on?

thanks

Sam

I-70 west

Yes, it comes with instructions.
No recalibration, just unscrew the old one put in the new.

Good luck..............

I had my throttle posistion sensor replaced. I was having the same problem

Glad I found this thread since I need to get a new TPS sensor to do my E-force install. I checked one of the Ford dealers which seems to have low prices on most ford parts and it's $10 cheaper!

Tousley ford has them for $54.98.

Use the same part number in the search of course, 6L2Z9B989C .

not to beat a horse here, do you think it matters if it is motorcraft or just a house brand like standard products, or the one I saw at autozone (duralast)?

06GT

Don't know, but if it were me I'd go Motorcraft.

Careful, there. Ford's replacement TPS is about 1/8 inch taller than the original TPS's and those newer size TPSs won't fit on the E-Force. Ask my how I know... The taller TSP doesn't fit in the small area between the throttle body and engine coolant shaft on the E-Force.

Fortunately, Edelbrock stocks the older size TPS's that fit on the E-Force. If you need a TPS for an E-Force, I highly recommend calling Edelbrock. They sold me one for $19.

....but I still have this new TPS from Tousley that doesn't fit.

To the OP, get a Ford TPS. If you can take out 2 screws and put them back in, you can replace the TPS. It is on the side of the throttle body. Just order the new part, then go looking on the side of the throttle body for a part that looks just like the new one you just ordered.

No engine re-calibration needed. However, you should reset your fuel trims. This is pretty easy. The process is to disconnect the battery for several hours (or as a short cut - a minute or two while you hold down the brake pedal). Assuming the new TPS is installed, reconnect the battery. Crank the car. Let it idle 10 minutes. Turn on the A/C and let it idle about 5 more minutes. Now go drive 15 miles. Done.

You may not even need to do that. But doing this makes the car re-learn how to handle that throttle body which may behave a little bit different with a new TPS part no it.

Guys, I want to totally thank you for the advice, got the part from Autozone, which was a ford part, it is a bit taller than the original one. old one off, new one on, started car, drove around neighborhood, ran great actually! This site just saved me from the Stealership!

As stated earlier, they wanted about $450 to do this same thing, do you think Ford cares that dealers are doing this to people?

Thanks again,

Sam

Yep, Ford's replacement is taller than the original. The taller replacement won't fit on an E-Force t-body. Ask my how I know...

Edelbrock stocks the smaller ones now. For just $20.

I-70 west

The older, smaller style is the problem, get the newer, larger one !

· The throttle position sensor (TPS) is located on the driver's side of the throttle body
· Remove the plastic engine cover to access the throttle body, then locate the TPS. You may be required to remove the hose that connects to the IAC valve as well as the metal bracket that mounts the plastic engine cover. You will want good access to the TPS to ensure you do not strip the screws.
· Disconnect the wiring harness that plugs into the TPS by pressing the locking tab and then pulling towards the front of the truck.
· Once removed, the TPS should pull right off the throttle body.
· To install the new TPS, position the front of the TPS at an approx. 45 degree angle downwards with the harness plug facing you, insert it into position, then twist back up until the bolt holes line up. Reinstall the bolts, using a small dab of thread locker on each to ensure they will not vibrate loose.
