I have a 2003 S-type jaguar that goes into a limp mode and stops running then the engine system fault shows ,the parkbrake fault and DSC not available also shows. Diagnostic showed codes PO121,P1582??


code p 0121 is associated with the throttle position sensor and accelerator position sensor
causes are from cable adjustment --throttle position and accelerator position sensors
code p0533 refers to ac refrigerant pressure sensor--high input== causes --ac pressure too high (cooling fault -condenser fan not running at radiator-- too much gas --pressure sensor
p 0105 refers to map sensor / barometric pressure sensor --circuit malfunction===causes wiring--- map sensor --baro sensor ECM
code p0566 refers to cruise control master switch== causes --control switch , ---ECM
code p1582 refers to electronic throttle monitor data available which will be associated with the p 0121 code and faults

04 cummins 3500 trouble code p0237


p0237 is an OBD-11 code and if it is applicable to a cummins engine it refers to manifold absolute pressure (MAP) sensor A, TC system---low input===causes wiring short to ground--MAP sensor---ECM
Try replacing the MAP sensor.

C3 1.4HDi 2003 engine fault light comes on during acceleration at 50 in fourth


the MAP sensor has a short to ground problem so I would consider replacing it and checking the wires and connections.

Check the map sensor, the wiring to it, check the hoses and pipes. Im 95% sure you have an overboost condition. Check the errors logged in the ecu.

Hi
More than just bad luck i suspect. Problem will almost surely be turbo overboost. Possible causes, wastegate jammed, actuator siezed, boost sensor inop. Best advice is to have fault codes and live data read with a suitable scan tool to determine the exact cause of the overboost condition. Easy enough job for competent garage.

Overboost condition


Hello, your car is probaly a variale vane turbo fitted and all you need to do is seperate the VNT part of the turbo, give it a good clean with brake/carb cleaner get rid of the sticky oily residue which makes the vanes stick on turbo causing a overboost fault, a delearship might tell you that your car has been remapped at some time setting the boost RPM at like 14 or 1500 and it should be like 2200 I do not know the specifics on your vehicle but a good auto manual will tell you at which RPM your boost should build. I would have a diagnostic done and see if this is your problem, if so do the above and go back and see if it fixed your overboost problem. If not, you will need your ECU remapped. I hope this fixes your problem!
