Hi All, for a while I've had numerous camshaft position sensor issues and P06DD (oil pump issue)
After having oil pump, timing chain, sensors changed and wiring checked I am down to P0394.
I can trigger it at highway speeds, engine warmed up and hot, engine under load, incline.
The CEL comes on and the traction control light, limp home mode (you all know the symptoms)
I am changing the PCM out next, for two reasons:
1. to eliminate this as a problem
2. to put a Daiblosport PCM in
The engine coolant gets to 109c (about 228f)
The outside temperature is over 30c (as hot as 40c) - I live in Sydney
The engine bay is really hot
I am running 5W20 oil
I am wondering if it is oil viscosity related.
I was thinking of having the fans come on earlier (Diablosport say their tuner can do this) to try to keep engine temperature down.
I am hoping that this will keep the viscosity higher.
I am also thinking of changing oil to 5W30.
