Check engine light came on and i pulled the code p0182. Come to find that it is the fuel temp sensor a low input. Unfortunately I can't find any posts regarding this sensor and a i searched for the part but i can't find one for the v6. i did find one for the v8 but i'm not sure if this would work. I need help figuring out if this is the sensor going bad and if so where is it located and where can i find one. This came on the heals of a limp home mode event which came up with a p0121 code. After a few hours, the restricted performance went away but p0182 is still there.

 

You'll probably need JTIS. It has the codes PDF (shows all the known causes of codes), Electrical Guides (show all the wiring and connectors, splices etc) and detailed mechanical info (where things are, removal etc).

Sometimes the same item has multiple names so be creative so you find them! (Looks to be EFT sensor in the codes PDF.)

You've a just about unique code so you may be in for some detective work essentially on your own unless someone happens to know about the sensor & its wiring.

 

Sebastian, as JagV8 mentioned you have a unique code (P0182).

I looked it up on alldata and as you mentioned I see the "fuel temperature sensor" location for the V8 motors and nothing for the V6. Although a quick google search came up with this site: GROWLER JAGUAR PARTS - S Type (New) scroll just about 1/2 way down and left of the 2 columns and they show a Jaguar OEM sensor (Part #XR8 36229) for a V6.

 

It's shown for the V6 in the Elec Guide so is probably in the rest of JTIS.

 

I am seeing that now, but as for location on the V6, there is nothing.

On the supercharged engine the sensor is located towards the front of the intake manifold, on the N.A. its location is towards the rear of the intake manifold.

 

hmm.... it's there to measure the fuel temperature (wow, who'd a thought) so it has to be near or in the fuel rail and from the stuff I saw it's wiring is in the IL (injector harness). How many unexplained sensors are there around there? "There" meaning in or around the V and the fuel rail etc.

I'm still looking but am short of time for this...

 

OK, if nowhere else it's shown on p29 of
Technical Guide
Jaguar S-TYPE
Sports Sedan
Powertrain
Introduction
February 1999
JJM 18 15 17/92
(or JJM 10 ... as that's the country code for UK; 18 is USA etc)

That's the original 3.0 but I doubt it's changed in that respect.

I think it's available on Jim's site (forum sticky for TSBs etc)

Brilliant!!

While you found the above, I had popped Joyces hood (bonnet) and removed the black plastic engine cover. The fuel rail system is somewhat hard to see because of the intake manifold, but as your attached diagram shows the "EFT sensor" right up front. With the fresh air intake tube removed, looks pretty easily replaced.

Funny though, screwing around for an hour or so looking this up (inquiring minds want to know), there really is not much information on US sites, seems more common on the European sites.

 

80% it's wiring/connector.

Wow, I finally looked on the UK forum and only 1 S-Type match, but it does say where it is. Wish I'd looked sooner (took ages to hunt this one down but got me woken up lol).

 

I saw that one mentioned on the UK site, but my puter wouldn't let me view the thread for some odd reason.

Here you have it Sabastian, in the matter of 12 hours, I believe your question has been answered!

 

It is directly under the schrader valve
The EFT sensor, located on the fuel rail, is a thermistor which has a negative temperature coefficient (NTC) . Fuel temperature is determined by the PCM by the change in the sensor resistance. The PCM applies a 5 volts to the sensor and monitors the voltage across the pins to detect the varying resistance. The PCM uses the EFT signal to adjust fuel pump pressure to prevent fuel vaporization and ensure adequate fuel supply to the injectors.
I hope this helps!

 

Thanks Gus, where were you 2 hours ago?!

 

Drinking my morning coffee!

 

Wow, once again you guys don't let me down. Took your advice and just as you stated, eft is the part. I can't believe no one in the states has it after market. Ordered it from the dealer with overnight shipping and tax it came out to $50. Will attempt the install tomorrow. Hopefully will be smooth and easy. Thanks again guys. I love this forum

 

Alright, quick question for the gurus, do you guys know which side would be side A. Figured I'd ask to avoid the headache of replacing one and finding out it's the other one.

 

If side A is Bank A then that terminology changed to follow the standard, so is now Bank 1 - and is the RHS.

But.... Isn't there only one EFT? In which case....

 

Not sure if there is only one but i noticed in the codes that there was a side a and a side b temperature sensor. Not sure if that's just there for the v8's or if i have 2 sensors in my v6.

 

I show only one on the 3.0

 

Thanks Gus. Anything special i need to know or is it pretty straightforward

 

Get rid of the fuel pressure by releasing it at the scherader valve first and that is on the top side of the fuel rail above the EFT Sensor. I would also suggest doing this when the engine is cold and I would have a few rags under and around to capture the fuel that will spill out when removed. When installing the new one take your time and do not over tighten or cross the threads. Caution should be taken not to twist the rail when removing or installing. Take your time all will go well. Be sure you do not have fuel that is pooled on the engine and leave the hood open to evacuate any fumes and look for leaks.
