Go to Auto Zone and ask the to run a diagnostic with their OBD-11 computer. This may still be a free service. Write down the error code/codes displayed. This should help pinpoint the correct sensor.

Hi is this petrol or diesel?


Most likely cause is one of 2 things, EGR valve Exhaust Gas Recycler or The air mass sensor

the EGR valve basically resends unburnt fumes back through the exhaust not dissimilar to a small turbo in its function and kind of does the same job on a smaller sacle. Quite often though they do not fail completely they just get dirty, you can remove this part your self and clean it with carb cleaner, do not use anything else but carburetter cleaner. you will notice inside the EGR is a small sensor very much like a small diode, spray this and clean the whole thing as best you can. be careful not to touch the sensor just use the spray for that part. then leave to dry naturally, shouldnt take long.

When these go or get dirty the car will feel really powerless, you might get 50 mph if your lucky maybe 70mph. they struggle on hills and you need to be in low gears all the time to get anything out of the car, also the light comes on. They cost for this model between £180 and £250 so its well worth trying to clean it first as this is most commonly the cause of failure.

the only other thing it could be would be the air mass sensor, again you can clean these but to be honest normally when these go you will have to buy a new one. unsure to clean all the connetction / wires to both parts also and ensure they have a good contact.

a new air mass sensor is under £100. if you need more info on these parts please get back to me.

Regards

Dan

I have a 99 jaguar xj8 van den plaus edition. It says resdtricted performance when it Gets warm and check eng. Light stays on. I replaced the computer any ideas


For the money you spent on another computer, you could have brought your car to a qualified mechanic and had the problem correctly diagnosed and repaired. 'Restricted performance' meant the computer saw something wrong in the engine, and restricted the performance to keep from destroying the engine. You killed the messenger and still have the same problem.

Fault code p1934 and limited power and sometimes engine management light this only happened since I drove through a deep puddle but the problem now only occurs when it's raining no problem when it's dry


Check the water proof covering of all the wiring connections as there is one that has failed and allowing water into the connection when it is wet . Seal with spray wax after drying out the connection

What's your problem? amber engine light stays on after starting my car


Hello
When the service engine soon light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.

My 2005 Jag S-Type 6 cylinder check engine light came on and while in parked position the check engine light started to blink yellow and stated "Restricted Performance" what does that mean?


You have a fault condition in the the engine management system - get the codes read to indicate where the fault lies ... It is probably just a faulty sensor as this is the most common cause of check engine warnings. The restricted performance condition is meant to protect the engine or components from damage, so don't panic - get the codes read - its probably not as bad as you expect. hope this helps - good luck.
