Question about 2001 Jaguar S-Type

1 Answer

2001 Jaguar S Type, "Failsafe Engine Mode" message with amber warning light, no power, then warning off and I drive on, 90 degree day, turn of AC and radio. About three miles down road second warning, no power, pull off road limping, stop, shift to Neutral, turn off engine, restart, drive off. No codes set. Car towed to repair shop, can find no issues driving car 30+ miles. Pick up car, driving about 6 miles the "Failsafe Engine Mode" comes on again, then goes off, continue driving with no more warning lights. 116K miles on car, re-engined at 42K due dealer error, no other issues with car.

Hello jpbreece i could be diappointed if i can't solve ur problem cz dis is wat i have been doin whole of my life..repairing cars!! espicially Jaguar, Mercedes, etc.. let me tell you its acommon problem and has asimple solution...let me go slow.... fail safe mode is something the vehicle computor will go into when there is a problem with the vehicle it allows u to get off the highway or road safely you need to take vehicle to repair shop or your dealer which ever u prefer Failsafe engine mode on a 2000 jaguar s type is caused by a stopped up throttle body. Jaguar says not to clean the throttle body since it has a protective coating to help keep deposits from accumulating. You can clean the throttle body as long as you use ONLY throttle body cleaner that states it is safe to use with a protective coating. The butterfly valve in the throttle body will actually stick not allowing air to flow into the manifold causing failsafe engine mode to kick in reducing the amount of power your engine will produce. To solve the issue just clean out your throttle body, it will cost you around $5 dollars and take 1 hour of your time.
Also it can be..
Limp mode initiates when the enginbe computer(s) note a problem that can cause serious damage to the engine or electricsl components. The car engages limp mode and will not go into higher gers as a protective measure.
My Car did the same thing; the dealer tested the car and told me there was nothing that could be done and that I should sell the car ASAP. I took the car home, opened up the computer under the passenger side floor board and found that the male-female connectors were not completely seated (some days the car drove well and other times I would have this problem, which almost resulted in several accidents on the highway). I pushed in the computer connectors and the car has been great ever since (2 years now). Therefore, check your computgers to see if you have a loos connection(s).
hope this helps
i guess this Old guy deserve a drink!!
cheers!! Safe drive n have fun.

The red light is for warning the amber is for caution so your caution light is on thats the amber the amber is reserved for local market like brake pads,oil change,or abs that affects steering stability, The information is exclusive only your driver handbook will define it

My jaguar started flashing the message "failsafe engine mode"


Go to your local garage (anyone) and have them read the OBDII code this will tell you what has caused the problem, cost for this should be minimal £7-10 ask them for all the reported codes you can check them out at http://www.bluejag.co.uk if you wish to find out what they mean.

Failsafe engine mode has no power


This is the way it is meant to be, first you will see amber and power is present and then red and power is minimal..

to get yourself out of trouble and as long as you are sure that the engine is not in danger of damage you can plug in a cheap scanner and switch off this warning so as to get you home..

You may need to do this a couple of times if you are some distance from home

Amber warning lights on.


I have a 2001 xtype and the same lights came on my dash, i had it plugged up to diagnostic and it was down to a split reluctor ring on the rear wheel, this set off the abs light which in turn sets off the management light. Will cost £200, but looks quite easy to repair by self

My jaguar s type has a new message- failsafe engine mode. when it was amber the car was ok but now that its red i have to limp home. how serious is this please. benn quoted a LOT of money at a jaguar main...


Sorry late reply - just seen this problem. The amber warning is basically saying a problem developing. The red and limp home action is showing more serious developement - But not always very bad news. Had car with same symptoms and it was a faulty sensor on engine, and another similar case was throtle position sensor. Get the car to a garage that can read the faults - so you know what the problem is that has been registered in the memory.
Hope this helps

Failsafe engine mode


The failsafe mode can appear following numerous faults being detected - some faults can be momentary and register but not cause a problem. These are normally reset by just turning ignition off/on. get the fault code memory read at a garage and this may give you a clue as to a possible problem developing. Failsafe mode will give you reduced engine performance but will allow you to drive for normally some distance. If a serious problem developes your car message centre will tell you to shut off the engine or it will shut it down.
good luck.

After all dried out, and jag dealer reset my failsafe mode all good....... until now i have a .500 ma draw on power while sitting unused, brand new batteries down in 1 week??

Warning icon and diagnotic message came on ''Failsafe Mode''


It sounds like your Throttle Position Sensor (TPS); located in the throttle body. (Diagnositic test may point to alternator or TPS; I experienced the same issue and although replacing an alternator is easier on the pocket book, it doesn't correct the problem; which will get worse.)
(My story) The amber transmission light would pop up; after a restart, it'd go off. Eventually this led into the engine dropping into safety mode (15-20 mph); while driving city/highway without fail everytime; inbetween driving distance became less and less. (prior to this I had taken my car in several times; each time they reset the computer and $$replaced my alternator, as suggested by my mechanic).
As soon as I drove it off the shop to my house, it dropped into safety mode; amber warning lights. Drove it back to the shop; had to replace the throttle body (the only way to replace a bad TPS). It can co$t anywhere from: $1700.00-$2,000.00 parts and labor. Shop around; because my shop diagnosed the problem part wrong, I got a deal (but it still cost me...). Since I had it replaced (April 2008), I haven't had a problem since. Jag Heaven (a parts company located in California) can ship parts anywhere; it was cheaper to do this than buy the part from my shop $aved $$$. Good Luck, hope this helps...
