"Engine Fail Safe" Displayed - Replace Throttle Body - Normally Aspirated Vehicles Only - Service Action S498
Issue:
As a result of investigations into throttle body failures, it has been revealed that a restriction of performance to the engine control system can potentially
occur due to a manufacturing issue with one of the throttle body components. This will result in the Malfunction Indicator Lamp (MIL) being illuminated
and the message, "Engine Fail Safe" being displayed on the message center.
Action:
On all 1999 XK8 and normally aspirated XJ8/VDP vehicles within the above VIN ranges, check the date code on the throttle body, at the next service
opportunity.
If the date code is within the range 10T5 to 11T25, inclusive, replace the throttle body as described in the procedure.
If, "Engine Fail Safe" is displayed on the message center after the throttle body has been replaced, please refer to Technical Bulletin 303-58.
