I am getting an issue which at around 50mph the car jolts and I get the traction control light on if I push it I then get an engine light and a limp mode The code is P0107 which is manifold pressure to low.
I have run through the diagnosis in the Bentley manual and all voltages check out and indeed I don't get an issue when stationary. I have a trace which shows the problem only occurs when the car is at >86c and the pressure reading is 0 (this is the difference between atmospheric and manifold pressure). Before that I get no issue with the pressure varying like it should.
So is it the MAP or the TMAP sensor? Could it be the bypass valve again? Anyone got any insights into this.
