2005 2.8 Crd Engine Light But No Fault Code Found

[dave62pb]

Hi , Need help my 2005 2.8 CRD as engine light on all the time on dash tried code reading by pressing trip button for 10 seconds

then switching ignition on /off 3 times as suggested on internet but nothing showed up so tried with a code reader into the port again no fault codes found

This last few days it has twice now lost nearly all power and crawled along untill stopped switch off for a while then re-start and runs ok, with no codes showing i dont know what the fault is,

Any ideas/advice welcome

Thanks

Dave

You'll need to get this key dance with ignition key done right as there must be a P code. Check under Key Dance on here. Your words of leave for a while then it starts maybe a clue to a sensor. Crank sensor has habbit of not leaving a code. But fuel system should be checked from filter to fuel rail of air getting in or leak off.

Hi Gordy

Thanks for the reply I tried the key dance as the youtube link but nothing shows also no P codes found on code reader, going to take a close look at fuel filter and housing at the W/E as read on net that housing can crack and wiring on plug can break down, keep you posted

Managed to get P code this eve by key dance  1st one P 0168.5 nearest i could find was  P 0168 (fuel temp too high ,cause wiring fuel temp sensor mechanical fault )

this is the fault I read about the fuel heater and wiring cause problem and heat cracks fuel filter housing

2nd code was P212 injector circuet malfunction , cause wiring injector ecm cylinder no 12   ???
