I have a 2003 s-type v8, m90009 (last 6 of VIN). I've been having problems with the car going into limp home mode. It happened like 9 months ago, and then went away. now it is happening quite frequently (just started a few days ago). Jag doesn't sell the TPS by itself, but the whole throttle body @ $815.00. The TPS is Denso 198500-3300, and I found it being sold in a UK store (just put the p/n in google), but they do not ship to US. Anyone know of a source to get this part, without buying the whole TB. I know how to check the Voltage for the TPS to make sure that it is aligned properly, so I am still confused as to why jag doesn't sell this one part by itself..

*edit - forgot to state, after it happens more than three times in short order, it throws a code which we scanned to be TPS signal out of range. This is why I am blaming the TPS (and also why I did nothing 9 months ago, because it never threw engine light). I also looked at the wiring going to the connector and it seemed to be fine, no cracking or whatnot.

If anyone has any information that would be great.

Thanks!
Justin

 

Removed my Denso 198500-3300 from my '05 Base S-Type SAJ...N16453 as it is acting up and throwing me code P2135. The device itself is sealed, protecting the dual potentiometers, but 90,000 miles of wear and tear has left a cold-spot on one of them (remember the old analog potentiometers on radios, you would move them and hear scratching-sounds in the audio). The cold spot will be on the most popular location, likely the idle location. By moving the device imperceptibly, you have moved away from the cold-spot; this happens whether you want to or not by detaching and reattaching. I did, however, want to make sure I was close so I took measurements before removing.

At 'idle' with pin 1 at the bottom, here are the resistance measurements I had:
1-2 2.055K
1-3 2.048K
1-4 2.129K
2-3 1.819K
2-4 0.687K
3-4 1.400K

After re-installing the device, 3-4 was made to be 1.403K at established idle, all that was needed to freshen things; but there is now a lack of trust and the new idle cold spot will wear more quickly with the existing 90,000miles of swiping wear. Most people that have taken their Throttle Body apart attribute the fix to cleaning (mine was immaculate already), but the real (or rather long-term temporary ;->) fix is the new location of the Throttle Position Switch.

Denso/Toyota, as an OEM, only sells directly to the manufacturers or specific distributors under agreement. Denso confirmed that this part is in fact under an exclusive contract with Jaguar and that they would be in a serious breech if they sold the part separately. I suspect remanufactured Throttle Bodys are merely this slight movement of the TPS to refresh it, so I do not trust them any more than I trust what I have done to stem the major cost of eventually needing a new part ...

I did some searching to try to acquiring the Denso part or equivalent. Denso(above), Wells, Standard, Beck Arnley, Replacement, OES, CarQuest, NAPA, Cardone, Jaguar (does not hurt to ask), as well as a series of other lesser jobbers (Excite autos of UK, Parts Bin, Parts Warehouse, Jaguar Parts Center) all say no, even when I had dug in and reported the mechanical and electrical specifications. The measurements above (1-4 2.129K mainly) will help in that search to allow others to compare electrical characteristics should an equivalent show up somewhere. Below is the actuator picture. Hopefully we can find a cross eventually?

I found many mechanical crosses out there in the above research, that operated CW as 198500-3300 does, but they were single-pot devices with limit switches (idle or full-open), rather than dual-pot devices.

198500-3090 TH148 5S5062
TH272 5S5173 5S5215 158-0817 5S5172 5S5173

 

I have had the same problem with the Restricted Engine Performance/limp mode. I changed to all new o2 sensors and EGR valve, and Anti Knock sensors. Car runs better but still the stalling problem when car goes to idle after driving at speed.

I called Denso and they wont sell me this TPS 198500 3300. But take a look at the website, Auto Parts Warehouse. There is an aftermarket TPS. Part number REPG314201. It looks exactly like the Denso TPS for the Jaguar according to all the pictures I have seen. It is between $64-85! Looks like it is for Lexus and Toyota.

I think I might buy this and try it out. Anybody have any comments on this TPS?

If your car is an "XJ8L" you may struggle to get any replies here in the S-Type forum, as your car is different and in ways that probably aren't obvious. I guess it's a V8? 4.0 or 4.2? Is it throttle-by-wire? Exactly which PCM? Also, SAI? VVT? VCT?

Generally stalling like that isn't due to TPS / TB, at least not on the S-Type.

What codes are you getting?

Also, what are OBD readings like such as fuel trims?

 

Same exact symptoms as I, moving the TPS sensor ever so slightly has proven to solve my problem (going on 2 months now, knock on wood). As indicated, I used the electrical values taken before loosening in order to reset it because it is spring loaded and will immediately snap to the end.Got that far too. They explained to me they had a contract with Jaguar never to sell the sensor through any other channels, and did not want to jeopardize their relationship. Orlando Jaguar sells the part for $2600 as part of a complete throttle body, but when pressed they were willing to go down to $1600 when I pointed out I could find it for $1200 from other internet-accessible dealers.

Now, you have a different car, so the following link may be a waste of your time, but the seller mse1828 might be able to get you a lead. The whole Throttle body for an '03.5+ S-Type for $500 eBay - Brand New In Box Jaguar OEM Throttle Body Genuine Jaguar XR845053it has a single pot (not dual like ours) and a limit switch. Mechanically identical, true, but not electrically.

 

There's always ebay UK. Complete TB more like $100. (TPS is just the sensor, that's what the S is for.)

 

Go ahead, rub our noses in it, you live in the UK

The first ones I found on ebay.uk refused to ship across the pond; and I bet if I could find one that would, shipping is not cheap (but cheaper than $500 certainly). It would cost me $150 to ship a six-pack of Indian Tonic from across the pond at union-shipping-prices (there has to be an underground at those prices). A TPS (Throttle Position Sensor) for most other cars are in the range of $30 to $80, but must admit the modern trend is to not unbundle them from the more expensive TB (Throttle Body). The TPS for the S-Type's sister car from Ford (Lincoln LS) here is $45 up to end-of-line, it appears to be the same one for the pre 2003.5's S-Types.

 

I hope someone'll ship stuff to you - we need the exports

There must be lots in breakers yards, all over the world where S-Types were sold.

 

Sorry for the continued negativity , but given that mine failed at 90K, why would I want one that has 70K+ on it? The potentiometer-based TPS is considered a wear-item or tune-up item on many vehicles. The lifespan for the other vehicles replacement potentiometer-based TPS units is listed 35K (yes, many last longer, this is a recommended replacement interval), roughly double the lifetime of most spark plugs. I do not replace my spark plugs with used units, I am not comfortable doing that with the TPS. I'd be looking over my shoulder worrying about it... Buying New In Box (even at Jaguar's prices) was considered for peace of mind.

If Jaguar had not sold so few S-Types (in the grand scheme of things), I would see enough of a vacuum to actually develop a hall-effect transducer and a small microprocessor with some digital potentiometers and sell a replacement lifetime TPS replacement unit. Since power is present at the transducer, I could do this without any hay-wiring, it would be better than OEM and 100% plug-n-play (like my GL2way device I sell in another niche market).

 

New is of course likely to last longer but for that matter plenty of wrecked cars didn't make it to 70K or even 10K

There are occasional TPS issues posted, but not many especially after you deduct the ones wrongly reported as TPS. They look to last longer than 90K.

 

Er... this is the S-Type forum but that's for an X-Type.

 

it seems to be the same part number as for s type, did jag use the same tps on x type and s type ?

 

This part is used on supercharged XJ, S and some X types. We need to place an order for a minimum qty of 50. I have posted on the UK website as well.

 

The price for gzsensor.com pieces (thanks for the reference BTW) is $6-$20/each, and with the 50 minimum, one may pay less to buy 50 of these than some of the used prices for an entire assembly, and certainly less than the Jaguar Dealer price on a new in box assembly should you end up with the higher-price in the range. There is an ebay listing for a new in box assembly out of california at $499/each though ...

I am still limping along with the 'repositioned' Throttle Position Sensor, forever fearful that the engine will go to limp mode at an inopportune moment.

I am requesting a price and shipping quote for 50 of these:

I received a response from the manufacturer. They indicate they are still making molds for the product and the references on the HK portal was to gauge customer demand and they tried to steer me to other sensor products in production (bait and switch in the OEM product domain). They will contact me in about two months time when they expect to be into production. Do not hold your breath.
