The O2 Sensors need to be changed at 100,000 miles, before they fail & you get a MIL Lamp on your dash
Just the front (2) closest to the engine, at the converter inlet
The ETC Failsafe, is most likely bad COP ignition coils Have to check for cylinder misfire count with a professional scan tool in Mode #06,unless you want to spend a few days walking a new coil from one cyl to the next
Always provide V6 or V8 in your question & lots of detail
it may not be a transmission problem. have you checked for fault codes to make sure it is not in limp mode? limp mode keeps vehicle from accelerating properly because the ECM has put the system at a limited setting to keep the engine running but not to its full potential.
You have a very bad COP Ignition Coil,that is spiking the PCM (computer)
The spike comes back on the TPS Sensor,then the PCM doesn't see the
throttle signal your foot sent thru, the pedal actuator (gas pedal) ,so it puts the
car into ETC Failsafe,and you can only go 6 mph.
If you got no ETC Failsafe, on the bottom right side of the dash, tell me what you do have
I need all the codes,if you have a MIL Lamp on ( the one that looks like a wrench)
Hello! Fail safe mode is when the vehicle's computer detects a serious problem an allows you to "limp" off the road or highway safely.
Fail safe mode on a Jaguar is mainly caused by a dirty and gummed up throttle body. The throttle body on your auto has a protective coating, so you can not use just any cleaner. It requires a throttle body cleaner that states "safe to use with a protective coating". The butterfly valve in the throttle body will actually "stick out". This causes fail safe mode to kick in reducing the amount of power your engine can produce.
Also check the plugs on your ECM (computer) and make sure they are all seated properly.
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.
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
