The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM or ECM,ECU), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems can and do cause many drive-ability related problem such as rough idle and other symptoms.

SOURCE: ABS, ESP, Level warning lights (2004 Allroad TDI)

I had the brake light switch replaced by a local dealer. Cost was $140 and it fixed the problem. Have driven the car for two weeks since and no lights and all systems normal.

SOURCE: jaguar s-type restricted performance

I had the same problem. Restricted performance and running rough at 3000 RPM. I have an OBDII code reader and found that the problem was in the air mass flow sensor, which is just after the air filter. I pulled this out and found it was dirty and had butterfly wings in it. The last shop where I had the oil changed replaced the filter for me but put in the wrong size. Close but no cigar. Bought some *** Flow Sensor cleaner at auto store and fixed the problem. Get an OBDII reader with the ability to erase the codes. Comes in real handy.

SOURCE: Security abs Brakes and low coolant lights stay on

These warning lights are often on due only to bad sensors and not due to bad systems. If your ABS brakes still pump themselves, for instance, you Antilock brakes are still working even tho the light is on. Whenever the check engine light is on it means that you will get error code messages about what the problems are by scanning the car's computer. If you have an AAMCO repair shop nearby drive there as they will scan your computer for free. Some auto parts stores also scan for free so call around. J.

Welcome to Fixya

First thing to check if there is enough fluid in the transmission. If yes then the most likely cause is the transmission or transfer case is gone internally.Sounds like a you need a tranny rebuild.

Thank you for using Fixya!

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.

Happens a lot. Always use the best high octane you can find. Check wire connections to knock sensor (most common cause for 'restricted performance light, sometimes outside temperature plays a part). Then disconnect negative terminal from battery, wait 2 minutes, reconnect. Then take car for a drive in various conditions, like city traffic, highway driving, and more. After several restarts, mine went away. Occasionally comes back, then disapiars. Ignore orange engine light.

Engine light on with restricted performance. I've scoped the issue and get a reading of PO 172. I've cleaned sensor and changed air filter. Still get restricted performance and check engine report....


this code is a rich code your car is burning too rich...meaning not enough air is mixing with the fuel...make sure you check all lines insuring that bank one doesnt have a clogged vacuum line etc..Bank one is where cyllllinder one is located or usually if your facing the bell housing while sitting in the car it will be the right side of the engine...But I would start with hoses,then go from there...

My S-type will sometime read restricted performance,ABS brake, engine fault,air bag and the engine light will be on dash bored-the car will not exceed over 15mph-if vehicle is park for 15 min of longer-...


its sounds like its between the oxygen sensor..and your throttle body sensor..Normally the difference between the oxygen sensor it will display all these things except the dsc mil.Make sure that you dont wash the engine caompartment near the firewall,this can lead to water getting into the TBS and cause the sensor to go bad,and also near the MAF in the air cleaner elbow.Water can short this sensor.But intermitant restricted performance can show do to a knock sensor malfunction also it will code p0327 or the oxygen sensor.Go by Antozone let them scan the car for codes and freeze frame data.The Actron obdii scanner does well with Jaguars.

98' Ford Windstar has a spongy brake


Have you had anyone try to clean and adjust the rear brakes? You will need a shop to scan the van for ABS codes first to cure the ABS light.
