SOURCE: 1989 jaguar xjs v12 fuel mixture

Chances are the coolant temperature sensor or its wiring have failed, or the vacuum line to the MAP sensor is leaky or broken (I believe the V12 in '89 guise uses MAP sensors). The MAP sensor measures Manifold Absolute Pressure. Along with this pressure the ECU looks at engine RPM. It also measures air temperature. Knowing pressure and temperature we know density, and knowing engine speed tells us how much volume of air is going through the engine. All of this together is computed into air mass and is used to calculate how much fuel mass should be admitted. If the vacuum line is broken, the ECU reads less vacuum and produces rich mixture thinking that the engine is under high load.

Location of OBD port on a 1990 or 1991 Jaguar XJS with a V12 engine.


A good chance that your car does NOT have one. OBDll was not required by law until 1996.
Some manufacturers had there own systems before then.
I found the following web reference:

"Sorry fellas, the 1989 XJS has no onboard diagnostics at all. It only has a red feedback monitor hookup [with a blanking cap] back near the fueling ECU in the boot. It was used for mixture setup and that's pretty much it.
The trip computer fault code readout didn't arrive until 1992."
The trip commuter readout he refers was a way to get codes (after certain steps taken) to show up in the trip computer display.
For OBDll compliant cars .... the port has to be within 3 feet of the driver with full access .... usually under the dash

Need radio unlock code for my 1994 jagaur xjs. Battery died, and now my radio is asking for code.


You will need to contact any Jaguar dealer service department (Preferably the one it was originally sold from) & give them the last 8 digits of the serial # & they can get you the code. If it is not the original radio for that car the radio will need to be removed to get the serial # off the radio.
They shouldn't charge you for this. If they try to call another dealer, you can call any dealer in the country for this.

Hope this helps

Radio code


  • The 4-digit code for your radio is listed on the two radio security cards supplied with the vehicle.
  • Enter the code by using the pre-set buttons numbered 1 to 6 and a "beep sound" occurs.
  • If the code is not properly entered, then begin the code entry again, starting with the first digit. If the code is not properly entered in three successive attempts the radio will not accept any entry until the radio has been left on for one hour (the radio display will show the word 'WAIT'). After one hour in the 'on' position the radio will accept three additional entries.

Note: Should you lose your radio security cards, contact your Jaguar Dealer, who for security reasons will require proof of vehicle ownership.

I hope this info helps!

2003 jaguar s type. unplugged the battery to try to rebut the car. now its asking for a code? is that something that would be in the manual that came with the car? is there a universal code?


Hi
The car is looking for you to enter the security (anti-theft) code for the radio.
If power is removed (battery disconnected), radio assumes it has been taken from the car and protects itself by means of security code. You should have a small ( credit card size ) security card with the radio code written on it. The instructions for entering the code is in your owners manual.

Regards
Martin

I need the radio code for a recently purchased XJS Jaguar


As an anti-theft deterrent, Jaguar began installing radios at the end of the Series III era which required the input of a security code to enable the radio to function. While coded radios are a pain, our experience is that they have drastically reduced the radio theft rates in major cities like Atlanta.
When cars with coded radios were first sold, the owner received a pair of plastic cards, about the size of regular credit cards, listing the radio code. When used Jags trade hands, these cards are forgotten and usually are not passed on with the car. And then when the battery dies and is replaced, the radio insists upon being recoded before it will work again.
One tip is that the dealer technicians frequently would write the radio code under the hood of the car in marker. There are also reports that the radio code was on a paper label which was stuck to the underside of the hood when the radio was installed. So if you do not have your code, it is a good idea to look under the hood for the paper label or for a hand-written four or five digit number. You may get lucky; we have known owners who found their radio code in this manner.
To recode the radio once you have the code, turn the car’s ignition on and then turn the radio on until the word "code" is displayed on the radio faceplate. Enter the radio code slowly and deliberately, firmly pushing on each button. If you have entered the correct code, after the last numeral is entered the radio will beep and then begin to play on the last station selected. If the radio has been uncoded for a long time, or if power has been removed from the radio for a long time, sometimes you will be unable to enter what you know is the correct radio code. In these cases, leave the radio powered, with "code" displaying, for an hour or so and then try to reenter the code. The code will usually take after doing this.
It is not possible to guess at the radio code and to just keep trying combinations of numbers until stumbling on the correct code. The radio will accept only three coding attempts before it locks up for an hour. Then you have three more attempts before it locks up for eight hours, then three more tries before it locks up for 24 hours, and so on. The times indicated may not be accurate, but the process is correct as described.
If you cannot locate your radio code, either from the previous owner or from the car itself, the only way to get the security code is to pull the radio to retrieve the radio’s serial number and to request the code from your friendly Jaguar dealer. All dealers have the ability to retrieve these codes, although they will vary in their willingness to do so for individual owners.
