Had the above vehicle in a few days ago the problem being poor starting, diesel knock and lots of white smoke. First I checked for a misfuel but all OK. Did a code read and got (P2338) Cylinder 3 Above Knock Threshold. Recoded No3 injector, no joy. Recoded all four injectors, still no joy. Took No3 injector to be tested and was told it was fine. When I refitted the injector I swapped it over with No2 to see if the fault moved to cylinder 2. I recoded the injectors to the correct cylinders but I,m still getting (P2338) code.
The odd thing is its as if the code wont clear. If I deliberately get other codes up by disconnecting various sensors they clear immediately but (P2338) remains without even starting the engine.
I.ve checked fuel rail pressure (1400Bar) and injector resistance (0.21 Ohms) on all four.
The only reading I,m not to sure about is the voltage at the injector harness. According to the tests section of my Vantage Pro I should have (5.00 Volts) with the harness disconected but I,m only getting (2.46 Volts) on each injector. I only got the scope last week so expert I aint!
Thanks in advance for any advice,
Mark.
