I have a small problem on my ED wagon.
Checked the diagnostics and came up with code 41, 52, 77
Got rid of the 41 (HEGO lean, because of running LPG at the time) and 77 (Goose code).
But have a problem with 52. Changed the switch over, but still no difference, same outcome, code 52, thats after erasing the codes.
Even moving the steering wheel, does not make the engine rev up a bit.
So I did some investigation and found that the ECU is reading 9.8V on the switch return (power from switch to ecu) when the wheel is turned. So checked the power getting to the switch and that was 9.8v.
I am under the impression that it has to be 12v ? Can anyone verify this?
Does the ECU feed the switch with voltage? Or is it from another source, as my wiring schematic shows that it's feed from the ECU.
