Hi, I have a Jaguar x-type 2.0 v6 2002, and i stalled it and quickly turned the engine back on, then the malfunction indicator lamp came on and won't go off. The car runs perfectly but this light remains, can anyone give me some advice please?

when you turn on your ignition to the point before engaging the starter all your warning lights should light up. The Engine Check Light is very obvious, except they throw convention to the wind and show it as 'Service Engine Soon' lamp 'Malfunction indicator lamp (MIL)'.
Page 63 - Section 2-7 Instruments and controls

Malfunction indicator lamp (MIL) If this indicator lamp comes on steady or blinks while the engine is running, it may indicate a potential emission control malfunction. The malfunction indicator lamp may also come on steady if the fuel filler cap is loose or missing, or if the vehicle runs out of fuel. Check to make sure the fuel filler cap is installed and closed tightly, and that the vehicle has at least three gallons of fuel in the fuel tank. After a few driving trips, the lamp should turn off if no other potential emission control system malfunction exists.

without going from bumper to bumper ????? You need to see what's missing after it dies , spark or fuel pressure . Don't guess ,test an if you don't know how ,take it to a qualified repair shop. Your fixated with vapor lock . Crank sensor , ignition module .

DTC P1599 will set if the PCM has detected an engine stall condition when:
• The engine is in run mode.
• The ignition voltage is present on circuit 439.
• The crankshaft position (CKP) pulses at the PCM are NOT detected.
DTC P1599 is a type D DTC.
The powertrain control module (PCM) has the ability to set a diagnostic trouble code (DTC) if the engine stalls when the ignition has not been turned OFF. This DTC may aid in intermittent diagnosis of a customer complaint of intermittent engine stall. The scan tool Failure Record information can be duplicated under the same stall conditions in an attempt to reproduce the occurrence. Since DTC P1599 is a type D DTC, the PCM will not command the malfunction indicator lamp (MIL) or SERVICE telltale On. This DTC can set due to driver error. For example, a vehicle equipped with a manual transaxle in which the clutch was released too quickly causing the engine to stall, will set DTC P1599.

EOBD II Error Code: P0117
Fault Location:
Engine Coolant Temperature (ECT) Sensor (G62) - Low Input
Possible Cause:
Malfunction Indicator Lamp (MIL) Triggered on first occurrence.
Coolant thermostat.
Wiring short to earth.
Engine coolant temperature (ECT) sensor.

EOBD II Error Code: P0340
Fault Location:
Camshaft Position (CMP) Sensor A (G40), Bank 1 - Circuit Malfunction
Possible Cause:
Malfunction Indicator Lamp (MIL) active.
Wiring from/to Camshaft Position Sensor (CMP) faulty.
Camshaft position (CMP) sensor faulty.
Timing misaligned.
Possible Solutions:
Check Wiring from/to Camshaft Position Sensor.
Check Camshaft Position Sensor.
Check Timing.

EOBD II Error Code: P0500
Fault Location:
Vehicle Speed Sensor (VSS) - Circuit Malfunction
Possible Cause:
Malfunction Indicator Lamp (MIL) Non Emission Fault - No warning light.
Wiring.
Vehicle speed sensor (VSS).
Engine control module (ECM).

P1388 Variable Cam Timing Overretarded (Bank #2)

Jaguar issued a Technical Service Bulletin related to this code ("Malfunction indicator lamp illuminated 3.0 l v6 false flagging of diagnostic trouble code P1383 or P1388"); reprogramming of the PCM should correct the problem

If your PCM already has been updated, then there is an issue with your variable valve timing system. It will need further diagnosis.

That is impossible to answer. You may find the following article helpful in understanding the question that you have asked.
Why Is My Engine Light On?

i have never heard of that code before I have heard of the P0603 code which is a trip malfunction indicator lamp.this is possibly caused by a failing ecu...the code is associated with the trip memory failure.You will have to have it checked at a Jag dealer.....they can check it for about 100.00 bucks..

I assume that you have the equipment to read the OBD codes, as you say there is no fault, this being the case you should be able to reset the fault indicator with this equipment. Otherwise you will need to perform drive cycles to clear it (you will find these at http://www.bluejag.co.uk ) or just sit back and relax it will turn itself off in time.

P0650 Malfunction Indicator Lamp (MIL) Control Circuit Malfunction

Malfunction Indicator Lamp (MIL) is located on the instrument panel. When the ignition switch is turned ON without engine running, MIL will light up. This is a bulb check. When the engine is started, MIL should go off. If MIL remains on, the on board diagnostic system has detected an engine system malfunction.

Possible Causes:

Harness or connectors (MIL circuit is open or shorted.)

MIL bulb may be faulty

discoonect the battery, turn the key 5-6 times to start then re connect battery. This will reset the computer and could reset the fault
