2002 Jaguar S-Type - Page 2 - Answered Questions & Fixed issues

the immobilizer is part of the pats security system the heart of this system is the instrument pack, all the modules on the can network communicate with each other to allow the car to start, recognize the correct key and plip etc.what is the problem with your car? let me know and i will try to help, cheers.

DTC Code P0153 DTC Code: P0153 Description: Oxygen Circuit Slow Response Bank 2 Sensor 1 Probable Causes:

1. Sensor or solenoid faulty
2. Connector terminal contact is damaged or corroded
3. Wire harness - Check harness for correct voltage, open, short to ground or short to voltage
4. Update control unit software - Check for the latest control unit update
5. Powertrain or Engine Control Module faulty
6. Fuel pressure - Pump, regulator, filter or lines
7. HO2S sensor contamination/damaged
8. Exhaust leaks or restrictions

p0420 and p0430 are codes for bank a and bank b catalyst efficiency below threshold. there are 2 sensors on each bank. you dont say if its a v6 or a v8, if its a v6 they are easy to get at from the underside. one has a green connector the other blue, both sides the same, and screw into the exhaust one before cat one after, if its a v8 there not so easy. the connectors are at the back of the cylinder heads one grey one black. my advise would to get it on to some diagnostic equipment to monitor live data to identify the culprit, you dont get both sides going down together. from my experience with these cars if one bank of cylinders has a emission related problem the ecu uses the other bank to compensate which can confuse diagnostics. also one of or both catalysts may be faulty

the code po153 is oxy/lambda sensor slow response. and the b i think relates to bank b that is left hand as you sit in car, there are 2 sensors on each bank. you should really have it put on suitable diagnostic equipment to monitor live data to help sort it out, it could be either sensor or the catalyst. and the parts are expensive so you should not get the diagnosis wrong. i guess you engine light is on. good luck.

u1400 is a code that i do not recognise, u140 is a body module coms fault code. what is the problem with your car? some fault codes on these cars are generic and will always be logged. hope this helps.

If the faulty sensor is one of the inner sensors the bumper has to come of. If it is a outer sensor only half the bolts on that side have to be removed. Start by partly removeing the under wing shield and there is access to the bolts,open the boot remove plastic shut trim and more bolts. Pull back side carpets remove the black side plates to get to more bolts remove bumper and replace the faulty sensor leave the bumper connected and pointing away and test before refitting.

Unfortunately unless you have a old "Bag Phone" or one that can be hard wired into the car - then you're out of luck. The system doesn't have a bluetooth availability unless you have the system modified by a professional audio installer or replace the old system completely.

Check all the fuses

has your car got premium sound system? if so the power amp is in the boot behind the inner wing trim panels on the lh side i think. and if it goes down it burns out ALL of the speakers, test the speakers with a ohm meter i suspect they are all open circuit

You probably need to replace the window regulator.

You need to know the fault code this will tell you were to start. You can check the the connections at the wheels and check the fuse.But with out the code your guessing.

Also replace fuel presure regulator

Front and rear map lights and sun visor lights are out . Glove box and door lights DO work. Leaves only one common wire that is orange and blue from the rear distribution block that is broken somewhere. A short should have blown fuses or melted the wire.

check bulbs not much else it can be unless wires on the back of bulb carrier have fell off but unlikley

Do the cooling fans come on at all?

the message "fail safe mode" is telling you that there is a fault in either the engine or gear box. In your case the problem is in the transmission. Run the fault codes and check for a torque converter servo/solenoid failure or a TCM problem. Check that there is oil in the transmission.

Thermostat not opening or Fans not cutting in!

You dont need to remove the drive shaft to tow a car. just put it in to neutral and take the hand brake off.

I recently had the same issue and it sounds like it could be fuel related. Have you recently changed the fuel pump or changed the fuel filter? If not there are several other fuel related fuses some in the passenger side fuse box, some in the trunk (which you have found.. but I believe there may be two) and some relays as well. Check all them. If all fuses are okay check to see if your fuel pump is getting power... this can be done by turning your key to the on position and listening under the passenger back seat (this is where your fuel pump is located). You should be able to hear it once you turn your key over to give it power..(now this humming noise will only last for a few seconds so have someone right there while turning the key) if not it is probably the fuel pump....

it may not be sealed properly or new housing is not tight or its cracked or it could be a loose hose clamp
