Hey guys trying to track code 0905 at the moment, can anyone tell me what voltage the sensor should read at idle and what other issues i could be looking at with this code
 
it should be around 2 volts at idle.
check the electrical connections. also check motor earths.

the books says high or low pressure fault, but dosn't say what pressure it flags an error at. it also detects faults on the wiring.

thanks for the swift reply can always rely on you mate!

so im getting 5.5v at idle what could be causing this? ive checked all the grounds they seem fine
 
sounds like faulty sensor.
5.5 is higher than its max output.
the book says that its the middle wire and its yellow. measure to engine ground.
does it change when engine is off but ignition is on ?

while i highly doubt it, also check with the hose disconnected. (i've seen people do weird stuff like shove ball bearings in vac lines.)
