Yeah I only have the one memcal so I just swap them around. The code is AWUZ which I believe to be 91 VP manual
Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
Yep, still interested (I guess that's one ).
Those MAP voltages look OK. I'm guessing that in Tumut you're not at sea level, where the engine off voltage might be closer to the reference - it's an absolute pressure gauge i.e. pressure relative to a perfect vacuum.
One check might be to compare the voltages with the sensor(s) in the Jeep with those from in the Hilux - they should be pretty close to identical. 0.1V or so difference is OK.
Maybe see what happens with the MAP code after the short is sorted.
if its idling at 1.6V its about normal around 30kpa
