Question about Jaguar XJ

Open Question

I'm looking for an original owner's manual so I can learn how to operate the on-board computer. The check engine light is 'on' (which I understand happens often on these cars) and it is prohibiting me from passing an emissions test necessary for auto registration.

Just maybe your O2 sensors are not operating properly. They may be requiring your engine to heat them up to get upper temperature readings but not lower. You can easily diagnose these and all other sensors and problems by purchasing a Hains manual at your local Auto Zone or Advance auto store which will greatly aide you in diagnosing all your auto needs. And the fault symptom index at the beginning of the book will ease your troubles with professional one on one advice with step by step instructions. Its like having your own ASE certified mechanic at your finger tips. Good luck.

Mass Air Flow sensor! Just remove your air filter cover. Go to Auto Zone and purchase some solvent. Spray past the air filter and it should correct the problem. If not, replace the Mass air-flow sensor. This is commonly mistaken for an oxygen sensor. Mine did this and I followed these steps and it fixed the light. BTW, the light stayed on for 5 years before I fixed it. Never hurt anything. It's normally something to do with emissions. Dummy lights. :)

SOURCE: Did not pass state inspection (vehicle)

First the fault codes,
U110C is No Fuel Level Bus Message
U0155 is No Cluster Bus Message.
Unfortunatly you have to be able to communicate with the instrument cluster with your scanner to diagnoise and I do not think an aftermarket scanner can do this.

How to brighten and dim dash lights in a 2004 jeep liberty limited 4×4?


Check Owner's manual. I have found on other situations the "dial"
to raise and lower light level is affected by corrosion. An extended effort of raising and lowering the light level may clean the contacts enough to allow proper adjustment.

Check engine


Check Engine Lights have been on all vehicles
for 30 years

Anyone owning a vehicle should have read some
owners manual & know about any dash light that is
on after the engine is running

This is 30 year old technology

You can study OBD2 Systems on the internet

You can Google any codes you get to learn about
the systems with a problem

2005 power window failurefo sport trac explorer


well lets start at the begining - if none of the windows are working take out your owners manual.
find the fuse and relay guide - look for the power window fuses, pull them out and check if they have been fused - like a light bulb burned out.
if so replace them with ones of the same ampage - the number printed on the fuse or ampage set in owners manual which ever is higher do NOT go over ampage in owners manual.
if fuses are ok look for the power windows relay - with engine off but key on have someone operate window switches and you listen and feel for relay clicking which means it is energizing.

Now with out any knowlege of how to use a volt ohm meter or understanding of DC electric it will be near impossable to instruct you on pulling the relays and testing them; test the drivers side window switch for power by taking the door panel off. testing the window motor for voltage going to it when the switch is in the up or down position and a common falure point in older cars the wires running from the door frame through to the door.
good luck

After my husband changed the battery in my STS, the CD player will not work. I have 3 CD's loaded in the player. It will not play or eject.


You need enter the unlock CODE for extract your CDs; check in your owners manual (any label in the last page .

THEFTLOCK is designed to discourage theft of your vehicle’s radio. The feature works automatically by learning a portion of the Vehicle Identification Number (VIN). If the radio is moved to a different vehicle, it will not operate. If the radio is removed from your vehicle, the original VIN in the radio can be used to trace the radio back to your vehicle.

With THEFTLOCK® activated, the radio will not operate if stolen.

Hope helps.

Hello,what meens: Check Engine on my dash board in red light?


All modern vehicles have a computer or the ECM (Electronic Control Module) that controls the operation of the vehicle powertrain (the engine and transmission). The main purpose of this is to keep the engine running at top efficiency with the lowest possible emissions. With constantly growing demands for better fuel economy and new strictest emission regulations it's not very easy to achieve. The engine parameters need to be constantly and precisely adjusted according to various conditions such as speed, load, engine temperature, gasoline quality, ambient air temperature, road conditions, etc. That's why today's cars have much more electronics than in early days - there is a large number of various sensors and other electronic devices that help the vehicle computer or ECM to precisely control the engine and transmission operation and monitor emissions.
The vehicle computer system has self-testing capability. When the computer senses that there is a problem with some of the components it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and your car needs to be looked at. ecm.jpgThe engine computer or ECM To properly diagnose what is wrong, you need to take your car to a mechanic or a dealer. The technician at the dealership or a garage will then hook up the scanner to the car computer and retrieve the stored trouble code(s). Then he (she) will look it up in the service manual provided by a car manufacturer. The service manual contains the list of possible codes (about few hundreds) and describes what each code means and what needs to be tested. The code itself doesn't tell exactly what component is defective - it only indicates where to look, what engine parameter is out of normal range. The technician will have to perform further testing to pinpoint a defective part.

2002 impala - service vehicle soon light appears at random intervals. put a code scanner on the car and no codes returned. opening/closing trunk seems to make message disappear....what is going on?


Service vehicle soon is not the same as Check Engine. This is a reminder to perform some regularly scheduled maintenance based on your mileage. Could just be an oil change. Look in your owner's manual to find out.

No low beams bulbs are ok fuses look good


There may be a relay that operates the low beam lights, check the owners manual to see if there is a relay, you should be able to hear it go "click" if there is one.

Can't find "Block Heater" plug-in on my 94 Cherokee Country


Hello,
Well the original owner may have got taken. I suggest looking nowhere near the air cleaner for the factorry installed Dodge, Chrysler, Jeep, Eagle block heaters are mounted on the side of the engine in a freeze plug port. There was an option available for the 4.0L and had a removeable 110 volt plug. You want to look on the side of the engine block and look for a 110 volt cord or a freeze plug with two electrical connectors sticking out. You may have to order the electrical extension cord from the dealer and is VIN specific. You may have to call a wrecking yard or dealer in Canada.
Good Luck.
