XJ6 Sovereign 1990 Jag. Transmission Sensor Light

Car was running fine until I ran it through a car wash (not touchless). Stupid error on my part. Now the transmission sensor light is on and according to the book, it's in limp mode. Took it to a Jag dealer and Jag does not have the equipment to test a car that old! Transmission shop says it's the sensor. Know where I can locate one? Or any thoughts on what's going on?

    I did complain to the dealer and called Jag direct....they gave me the same answer.....22 years ago they didn't have the electronic testing equipment to test the car. Yet they install the stuff....frustrating! Love the car......it only has 58 K on it.....hope the shop can find the sensor so we can continue to drive it.

SOURCE: changing rear shocks on a 1990 jag

No. But if can't get it on a lift or high enough to work under comfortably..it will be very awkward. The calipers get in the way when you are removing the springs and shocks as a unit. You can move the part and get it out and down, but you will need to remove the rear wheels and let the rear springs hang down.
Make sure you have a good spring compressor to get the old springs off....in most cases it is the springs that go soft and not the shocks...
Don't assume that it is the shocks unless you know for sure they are bad.

SOURCE: 1990 jaguar xj6 transmission problem

Hi Virtgen

If you have checked your automatic transmission fluid, and its OK.
Does it smell burnt ?
Sounds like you have a mechanical problem in the transmission.

The ABS light on is another problem.
This is usually associated with a rear ABS sensor faulty, due to corrosion in the rear hub.

Give me some feed back !

SOURCE: 04 Jag xj8 set brake code is on---limped home

When this happens, usually you have to replace the Computer. There is a chance you just didn't reset it when you took to cables off. Remove them and tape or hold them together for 5minutes or longer. If it still does it, I would get a book and find out where the code is to lead you. With the obd it only gives you a starting point in the diagnosics. You may have air in your lines that need bled, a sensor out, or just plain adjustment of the cables. But it shouldn't go into limp home mode unless you lost your Engine Control Monitor. Oh, I didn't click the read more button. Check the E-brake cables. You may have run over something that hooked it and ripped it loose. The Jags can tell if the cable is too far out of adjustment. It's under the car, cable should go through the floor and run to the rear of the car and Y out to the rear wheels. Good luck.

1990 jag xj6, 4.0 eng, 114k, plugs, wires,cap&roter, fuel pump, oil&filters changed. car runs fine but fails to start at times for several days then will start on first crank and run like a top;...


under the coil is mounted a bosch ignition module with seven connections on it ,renew this module thats all it needs ,if that doesnt work change the front crank sensor ,one 10mm headed bolt holds it it on ,either one of these could have a intermittant fault ,the front crank sensor is a jaguar only part and costs about 50 euros the ignition module is a standard type and is available from a auto factor if its in your hand as it doesnt show in the catalogue but its the same as a vw golf ,vw transporter and some citreons and peugeots as well ,should not cost more than 35 euros

I have a 1990 Jaguar Sovereign, 98,000 miles. The problem I'm having is the engine starts and runs, but it lopes at idle and runs rough, seems to be running too rich. I was getting fault codes 44, 37,...


I would change the air filter and clean the fine mesh covering the air flow control unit.
Make sure the connections are good as the sensor screen is tied to the O2 sensor. A new O2 sensor and dirty screen would give you poor fuel burning as the air fuel mix would be bad, and the O2 sensor would read the need for more fuel.......poor economy and running rough as it would not be clean burning.
