Jaguar S type 2003 Ignition amplifier bank2 location

Thank you for your answer Paul. I have a OBD code P1368. I get a limited performance alert on my dash when it happens, the "limp home mode" but it only happens very seldom, maybe once or twice every few days or sometimes every other day and it only happens for a few seconds or less. Otherwise it runs great. I've worked on cars all my life starting in 1965 and was the crew chief on a spy plane in the Army '69-'71 so I have a lot of experience and this seems to be an intermittent short more than a bad part because most of the time the car runs perfectly. idk, can you offer me any advice here.

good morning, the fault code you have from memory is allways logged its a system check ok code and is put in each time you cycle the ignition on/off all powertrain codes normally start po. ie. poo68 is absolute manifold pressure sensor or wiring fault poss air leak? po368 is camshaft position sensor high input shorted to B +v. pi codes are body codes i would start by having good look at the engine harness and connectors for chaffing etc. if no luck check the powertrain control module for water ingress an connector corrosion. the module is not easy to get to its under the plastic housings on the rh has you look under bonnet under the cabin filter housing i am calling in where i worked on jaguar all my life until i retired 4 years ago i will se what i can find out anymore clues. good luck good morning, the fault code you have from memory is allways logged its a system check ok code and is put in each time you cycle the ignition on/off all powertrain codes normally start po. ie. poo68 is absolute manifold pressure sensor or wiring fault poss air leak? po368 is camshaft position sensor high input shorted to B +v. pi codes are body codes i would start by having good look at the engine harness and connectors for chaffing etc. if no luck check the powertrain control module for water ingress an connector corrosion. the module is not easy to get to its under the plastic housings on the rh has you look under bonnet under the cabin filter housing i am calling in where i worked on jaguar all my life until i retired 4 years ago i will se what i can find out anymore clues. good luck

have been in to my old work got on to the jaguar technical info system using a friends password. the code p1368 is a jaguar related code not a generic code which may relate to a internal powertrain module fault. i bet if you remove the powertrain module connector its gone green and corroded. common prob now these cars are getting older. a good clean. with say brake cleaner or something and apply some contact grease it will be ok. but make sure the module has not got water in it remove it from the inside of car in the footwell lh. and let it dry out then make sure you waterproof the connector and all the seals around the removed plastic panels are ok. hope that helps have been in to my old work got on to the jaguar technical info system using a friends password. the code p1368 is a jaguar related code not a generic code which may relate to a internal powertrain module fault. i bet if you remove the powertrain module connector its gone green and corroded. common prob now these cars are getting older. a good clean. with say brake cleaner or something and apply some contact grease it will be ok. but make sure the module has not got water in it remove it from the inside of car in the footwell lh. and let it dry out then make sure you waterproof the connector and all the seals around the removed plastic panels are ok. hope that helps
