Question about 2000 Jaguar S-Type

1 Answer

My 2000 Jag S type also keeps saying failsafe mode?

I keep getting failsafe mode flashing then my Jag cuts off as well. What is the problem? I can't get it inspected until that is fixed? Is it that the computer needs reprogramed?

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.

My care keeps saying failsafe engine mode and it keeps cutting off? Do you by any chance know what's wrong?


Many things can cause this message, get it to a good jarage and have the fault codes read - this will tell you what is going on. Don't panic - it could just be a faulty sensor .. these cars are very prone to this. Try to avoid using a jag main dealer for the code readings as they are expensive and tend to ''overcompensate'' for repairs! Most good independant garages have the ability to read the fault codes.
Hope this helps - please post the fault when know.
