My tuscan developed a fault the weekend where it became very jerky on light throttle. To cut a long story short my mate has plugged it in tonight to check fault codes etc.One of the tps was a little erratic and it looked like it was knocking a lamba out.We changed the tps and all was fine, lambas working as they should and the car ran completely different, ran as good as it could but the EFI keeps coming on the display.The other fault it has developed is a fault with the oil pressure sender/gauge, the display now reads 99psi, is there any way this could put the EFI warning on. I noticed the EFI warning around the same time as the oil pressure died.Thanks
It's possible.
I've not looked at the fault conditions for the oil pressure, but the signal is fed to the ecu and is checked against a mapped table of pressure v revs. If the pressure is too low relative to the expected figure at those revs in the table then certainly that brings the oil light on but not sure about the efi fault warning. Do you ever see the oil light on with engine running?
