Since June my 2014 Explorer has spent a total of 29.5 days in the service department for defective throttle bodies?! Anyone else experiencing this issue?

 

[gdonley308]

Has anyone else experienced a throttle body failure on their Ecoboost?

 

[ajpturbo]

Maybe the JMS boost and pedal max didnt work so well.....29 days for a throttle body?..just swap a new TB

 

[SHOdded]

Sorry to hear!  1 incident or multiple?  Very rare to hear of TBs going bad, but happens time to time.  Usually a bad motor/integrated motor-sensor.  What is the svc dept telling you?

If you search wrench light followed by "terrain system management fault" online you'll see this is actually an epidemic. They don't keep the throttle bodies in stock. They said if I installed a BBK they'd void the power train warranty because it says " not for emission controlled vehicles". The JMS doesn't cause this, it's happening to stock Ford vehicles allot. North Carolina petitioned NHTSA to have Ford recall every vehicle with these throttle bodies. Fords answer to avoid a massive recall is to give you a 150,000 mile warranty and 100% customer satisfaction. When this happens the car loses all power and limps at 15mph with the gas pedal doing nothing. Can't shift, power steering is affected. 14.5 days in service dept. in June, 15 days in October. The saddest part is, Ford could care less and they're well aware of this issue. A 17yr old girl died in North Carolina when she pulled out and lost power then a semi hit her.

I was curious if they looked at the TPS because i know in some earlier versions,models that a new kit was released to remedy similar issues.  Z

This was #2 in four months?! The electronics part in Mexican made.

 

[ajpturbo]

Does it do it when stock?

 

[gdonley308]

Yes, it's being reported allot on vehicles 2011-2014 the most. Do a search "Ford Vehicles wrench light followed by terrain system management fault", I think you'll be as shocked as I was, by the number of these incidents

 

[FoMoCoSHO]

Who told you they would void your entire powertrain warranty over a bbk?

 

[SHOdded]

It's been a problem for many vehicles since ETBs started being used at Ford, the first big brouhaha was with the Fusion.  The Edge has had its' share.  Wasn't aware that the Explorers were affected as well tho.

 

[ajpturbo]

I would take off the boost max and pedal max and return to stock?

So why has the dealer had it sooo long?

Was torrie aware that you had those contraptions latched on to the vehicle?...im curious .

similar thing happened in my 2003 Nissan Maxima... these electronic throttle body's have had issues for a long time

The problem usually is the delivered tq vs actual tq and the calibration itself and not the actual hardware or throttle body..All calculations for torque delivery in the tune start at the pedal with modern drive by wire....the OEM is trying to fine tune the feel of the power delivery then conflicts with the calculations are created within the tune inadvertently

So your saying this is usually a tune problem?

 

[ZSHO]

Here is a wiring Diagram of the ETC and APP sensor.....did they try updating the PCM to the latest cal?.  Z 

 

[gdonley308]

Has nothing to do with tuning. This happened when it was stock with no tune or JMS hardware last time. It happens on stock vehicles all the time.

He didn't say the issue was having the car tuned, he said the issue was the tune itself. Even the OEM tune, as engineers contradict themselves when they dial it in, on one hand they want superior pedal feel/driveability, on the other hand - reliability. Where you cross the two is the issue.

It looks like the Delphi Gen 6 electronic throttle bodies cause the vehicles to enter "limp-home" mode and throttle bodies that experience electrical problems with the powertrain control modules..Z      http://www.carcomplaints.com/news/2016/ford-throttle-body-problems-lawsuit.shtml

There are electrical issues with the motor/sensor.  One of them being carbon tracking that builds up and interferes with communication and hence computer control.
