Explorer EFI Mass Buy Feeler.

[DirtDonk]

I attempted to cross-reference the tps sensor for the 96 model. Unfortunately I get absolutely nothing which I find extremely strange that ford would make a specific tps for only one in vehicle.

While I would normally agree with that statement, it's entirely likely that the Explorer has it's very own unique setup. After all, that was literally the last iteration of the old engine, that was literally in no other vehicles at that time.
And with calibrations for smog and such, along with the upcoming new combustion chamber design and different EGR setup, not to mention the first DIS for a 5.0(!) and it seems very likely it's got several of it's own unique sensors.
In fact, I'd be surprised if even some of the other sensors weren't semi-unique to that platform as well.

But, as we've found out many times, just because something Ford did makes sense to someone, don't make it so. So hang in there and somebody might have an alternate. May be Garry/EFI Guy.

...Also, does anyone know if the Mustang TPS has the same output as the Explorer TPS?

Sorry, forgot this part of your question.
Again, I don't know for a fact, but many of the TPS sensors actually had the same range. Just different connectors and possibly different interfaces between it and the throttle body.
So while the readings might be the same (or might not), they might still not be compatible with an Explorer throttle body.

Sorry chuzie. I didn't even realize this was EFI Guy's original thread. Was just responding to a notification and thinking it was a different one you'd started.
Obviously he's the best to answer that. So I'll just put the keyboard down, and step away from the computer!

Garry knows, here it is.

.....Only 96 and very early 97 TPS sensors use the round plug. Late 97-01 use the oval plug (there is only 1 oval plug AFAIK). The TPS sensors will interchange between any year (and even Fox mustang stuff) if you change the plug out.

What I do not know is if the TPS sensors will all interchange as far as bolting them to the throttle body. I don't know if bolt spacing, and shaft height / indexing are the same or not.

I know that the 96' TPS won't bolt up the newer throttle bodies that use the oval plug. The bolt spacing it different. I spliced an oval plug onto my 96' harness. My 5.0 is a 98', harness and ECU is 96'. I couldn't use a 96' TPS, I had to change the harness.

Must have missed that. Thanks.

Paul, Don't log off, we need you here 24/7. I'm always learning stuff reading through your posts.

Someone correct me if i wrong, but swapping a mustang tps harness plug onto the 96 Explorer harness. The pin out should be as follows (explorer - mustang tps) :

SIG RTN: GY/R - B/W
VREF: O/W - BR/W
TPS: GY/W - GN

 

[garberz]

Hmm? The Mustang tps harness plug is the same as the 96' Explorer plug. Round plugs. I'll go check my 98' plug (oval) on my 96' harness and see what the pin out is.

[chuzie]

They are slightly different and won't mate so i am swapping the Explorer plug for a mustang

 

[chuzie]

I am questioning if the tps os interchangeable now. What was previously reading 0.98 on my Mustang setup is now reading 0.2 and there is no way i would be able to elongate the mounting holes in the tps enough to get the reading where it should be.

X2!

Fixed.

I believe you can remove the pins and swap just the connector body. No need to splice.

 

[garberz]

My pin out is:
98' oval plug -----------------96' harness
Blk/Wht- Ref voltage --------Brn/wht Ref voltage
Grey/red- Sig return --------Grey/red- Sig return
Grey/wht TPS in -------------Grey/wht TPS in

Why the Mustang TPS? What throttle body are you using? I'm trying to get caught up on what you're doing. My set up is a bit different than yours.

While I still had my Mustang set up I got a throttle body from a 96 Explorer. It was compatible with mounting my Mustang TPS and gave me the ability to reduce airflow restrictions since I was using a larger MAF.

I would like to keep the current throttle body since I have already accomplished the Mustang linkage modification. The drawback I see is having a short supply of available TPS at the junkyard.

I am on my way to the parts store to pick up a new 96 Explorer TPS as it will be cheaper than purchasing a used throttle body, TPS, and re working the Mustang linkage.

 

[EFI Guy]

I'm personally running a Mustang TPS on a 96 Explorer TB with a 98 PCM. The TPS fit a little weird on the TB. It was like I had to get it perfectly centered or else the throttle plate would bind. But it works, and the voltage range is perfect.

 

[garberz]

OK got it, I'd give you my new 96' TPS if you were closer. I bought it thinking I could use it on the 98' throttle body, instead of changing the harness. That didn't work.

 

[chuzie]

Tps was bad. Good to go.

Last item on my list is p0340

Engine running, then the PCM detected that the CMP sensor signal was missing.

Anyone have troubleshooting data for CMP?

 

[EFI Guy]

P0340 can set if the signal is missing or if it is too far out of time. Did you set it on the compression stroke at TDC with the tool? Are you using a 3 wire sensor with the correct half moon type of synchro? Also if it is a used sensor, there is a little magnet molded in to the housing of the sensor, I have seen them fall out and set the code.

 

[chuzie]

Grey tool at tdc. I will set it up again just in case.

 

[chuzie]

Found the problem.... Damn. Back to lkq.

 

[EFI Guy]

Yikes! The synchro looks bent, did it shred the sensor when you hit the key?
