This problem started brewing a couple of months ago. At which Time, I could drive the car for a while before I would get a restricted performance and amber light. Now, as soon as I start the car it goes into Engine Fail Safe mode with an amber engine shaped light and a red warning light, No Traction Available is also displayed. The throttle does not function and the engine idles rough. I have not driven the car since it started doing this, however I do start it and let it idle. What do you think could be the problem?

That is the PCM putting the car into "fail-safe"mode to prevent possible engine damage. You will need to have the PCM scanned to see what codes are in the memory. These codes will lead to the root of the problem

Can I scan the PCM codes with an Actron CP9410 Pocketscan Plus Diagnostic Code Reader for OBD2 vehicles? If not, what type of reasonably priced scanner would you recommend?

I looked up that scanner on Actrons site and it doesnt say if it will do Jag's.I would talk to someone there first, too verify it will work.

I purchased the Actron CP9550. It provided me with the following codes: (P0351) Ignition Coil A Primary/Secondary Circuit Malfunction, (P1111) Intake Air Temperature (IAT) Sensor Circuit Intermittent High Voltage (P1121), Throttle Position (TP) Sensor Circuit Intermittent High Volatage. Can you please elaborate and advise if I can repair myself. I have basic part changer mechanical ability and can follow directions. Thanks.

First clear thecodes and run the car to see what comes back first. Sometimes one thing can set off another. The ignition code could be bad wiring, bad ingition module or abad coil.I would venture that the coil is bad, since it is only giving a code for 1 cylinder, the 1st cylinder on the right side of the engine.I would take care of the misfiring first, then drive it to see what comes back. May also want to install a new set of plugs at that mileage

Okay. Now, as I stated before, I can change parts. However, that's only if I know where they are. Where can I find the coil on this car? Is it a 4 pin or 2 pin coil? Also is the right side of the vehicle the passanger side and is the #1 coil going to be from the front of the engine or the back?

I found the coil under the coil and plug cover. Now I just need to know which one is #1 on the right side. Again I'm assuming passenger side facing engine, 1st one being from left (1) to right thru (4).

Looks like cylinder 1A is the passenger side, closest to the front of the vehicle

Thanks. Hopefully this will resolve some, if not all of my problems. Jag dealer wanted 397.00 for a 4 pin coil and 89.00 for a 2 pin. Still unsure of which one it takes. It has 4 wires so it must be a 4 pin. I found a 4 pin online for 128.00. May take awhile to fix. Still searching for best price. I'll let you know what happens.

Part arrived, I installed it. The red engine fail safe message went away, but the check engine light still remained. It idled fine for about three minutes. I was even able to rev the engine for awhile. Then everything returned to previous condition. ASC not avail, Trac not avail, engine fail safe, extremely rough idle and no throttle response. I rechecked the codes as I had previosly erased them. (P1121) Throttle Position (TP) Sensor Circuit Intermittent High Volatage, (P1000) were the one's displayed. I don't know what the 1000 code is. Furhtermore, you told me to clear the codes, drive vehicle and see what comes back. I must have failed to mention the car was not and is still not drivable. I mean it idles and goes into gear, but I cannot accelarate. Also prior to receiving the new coil, I switched the alleged bad coil with a good one from the other side of the engine expecting to get a bad code reading from the new location of the bad coil. No new code. So, 96.00 for Actron Scanner Tool, 139.00 for Coil, 10.00 to 2carpros and I'm still searching for a solution. What next? Do you honestly think we can fix this or do you reccomend taking it to the shop.

I was hoping we could at least take care of the misfire. Those Jags use Ford electronics adnengine controls, which can be misleading when it comes to "coil" codes. Since you are capable, try swapping the injector for 1 to another cylinder, clear the codes and see if the miss follows it. The big problem will be with the TPS and lack of ablilty to watch it work through a scan tool.

As much as I hate to admit it, you may need to have a shop take care of that issue, but the misfire we can fix. Take that coil back off and put it on EBay to recover your money.

Thanks. I'll just keep the coil as I may need in the future. I don't think it's a misfire. I think when the car goes into fail safe mode it lopes like that. Could this problem be (1121) TPS? Could this be the real problem? I heard they often go out. Futhermore, I heard the part (Throttle Body) is very expensive because you cannot just buy the sensor you have to buy the entire Throttle Body. Do you know of any place that will just sell the sensor?

Hey. hope you don't mind me adding a little !!

Take the vehicle to a dealer and have them reset the throttle cable .. you can perform this repair yourself (with patience and tools)but it is best and quicker when done by a dealer using the WDS system ! repair (labor) time on this repair is .6 (35 mins) so do not let them charge anymore ... LOL

LIMP-HOME MODE - DTC P1121 AND/OR P1632 - AJ27 ENGINE - ADJUST THROTTLE CABLE
TECHNICAL SERVICE BULLETIN
Reference Number(s): 310-05, Date of Issue: April 01, 2002
JAGUAR:1999-2000 MY XK8 Range; 1999-2000 MY V8 XJ Series
SECTION:310
VIN:031303-A04950; 853936-F08942
Superceded Bulletin(s): SECTION 310, NO. 05, Date of Issue: August 01, 2000
Related Ref Number(s): 310-05
ARTICLE BEGINNING
Issue
NOTE:Remove and destroy Bulletin 310-05, amended 08/00. Replace with this Bulletin. Procedure has been revised to use the WDS.

Some of the above vehicles may default to limp home mode because the throttle cable is improperly adjusted. The condition will be accompanied by diagnostic trouble code (DTC) P1121 and/or P1632 being stored in the memory of the Engine Control Module (ECM) or Transmission Control Module (TCM), respectively.
Action
On a customer complaint basis only, when diagnostic trouble code (DTC) P1121 and /or P1632 is stored in the memory of the Engine Control Module (ECM) or Transmission Control Module (TCM), follow the workshop procedure outlined below.
WORKSHOP PROCEDURE
Open hood and fit fender protector covers.
On V8 XJ series vehicles only, remove engine bulkhead covers.
NOTE:Check that Worldwide Diagnostic System (WDS) has the latest level software.

Position WDS along side vehicle, switch ON' and allow software to load.
Open front door and connect Portable Test Unit (PTU) to vehicle diagnostic socket using diagnostic cable.
Enter the VIN, select engine system from content model, navigate to data logger and allow software to load.
Clear all pre-selected signals.
Scroll down available signals, select PPS11 and PPS2.
Select signal-monitoring screen.
Turn ignition 'ON'.
Start recording data.
Cut and remove ratchet strap securing throttle cable to abutment bracket.
Displace and reposition throttle cable adjuster from abutment bracket (throttle in its closed position).
NOTE:Ensure there is no tension on cable.

Note voltage reading of PPS11 and PPS2 on WDS.
Partially insert throttle cable plastic adjuster into abutment bracket.
Re-check PPS11 and PPS2 voltage reading on WDS.
NOTE:If voltage readings are higher than original readings perform the following steps.

Adjust throttle cable until the voltage readings for PPS11 and PPS2 on WDS are at the same value as first noted.
Slacken throttle cable plastic adjuster one more quarter of a turn.
Fully seat throttle cable plastic adjuster into abutment bracket.
Install and secure new ratchet strap around throttle adjuster/abutment bracket.
NOTE:If the voltage readings are the same as the original readings perform the following steps.

Adjust throttle cable until the voltage readings for PPS11 and PPS2 on WDS increase.
Adjust throttle cable slowly until original readings are obtained, do not over-adjust.
Turn throttle cable one quarter of a turn to obtain minimal amount of slack in inner cable.
Fully seat throttle cable plastic adjuster into abutment bracket.
Install and secure new ratchet strap around throttle cable adjuster/abutment bracket.
NOTE:After throttle cable adjustment (carried out above) follow steps 16 to 21.

Check and where necessary, operate throttle pedal twenty times to settle cable.
Adjust kickdown switch. (Supercharged vehicles only)
On normally aspirated vehicles, if the required throttle opening cannot be achieved due a lack of adjustment range, a shorter length throttle stop stud may be necessary. Measure the distance of the length of the hexagonal section (points A and B, Fig. 1). Select the next shortest mounting stud. Refer to the Parts Information for the total of 4 different length studs are available.
NOTE:It is unlikely that a new throttle stop mounting stud will be necessary since this component is hand selected and installed in production where a test of full throttle has been performed and passed.
Order parts on an as-required basis only.

Hope this helps

Thanks. Wow! Now that seems like a real solution. I will have the car towed to the dealer on 3.15.2010. I'll let you know if this reccomendation resolves the problem. I sure hope so because this could potentally save me $1,500-2,000.
