2003 KJ 2.8CRD Cutting Out-P0076 and 5E90 Error Codes
Hello
I have developed an issue with my 2003 KJ 2.8CRD cutting out. It doesn't happen on every single journey, but at least once a day - and when it does happen, it happens at pretty much the same point - after about 30 minutes of driving.
The engine just dies; I lose power and have to pull over to the side of the road. Interestingly, I get absolutely no warning light coming on (no CEL) only the oil light coming on as the engine slows and the oil pressure drops. Then I simply have to turn the ignition off...then back on..start it up and I'm away.
I've had it into the dealer and they couldn't find any codes, but they suspected a Crank Position Sensor, so I had this changed (made sure it was a genuine Mopar). Thought this had solved it, but after 2-weeks the problem came back.
Took it to a local auto repair and managed to borrow a reader and the last time it happened got the following:-
5E90 - Active Power Up at Speed
P0076 - Intake Valve Control Solenoid Circuit Low Bank 1
No idea what either of these mean...and can't even find any reference to the 5E90 code when I Google it??
Can anyone advise?
It mainly seems to happen when I'm pulling away from the side of the road or out of a junction or hard accelerating to overtake another vehicle - i.e. When I put a bit of stress onto the gearbox - so I'm thinking it’s related to the auto box shift up / down???...but really, I'm at a loss as to what may be the cause, so would welcome any suggestions??
