anyone shed some light on what might cause these problems and possible fixes for them???
31 Engine RPM signal (crankshaft sensor) No signal
66 Carbon Monoxide (CO) potentiometer High voltage
73 Air Flow Sensor (AFS) Low voltage
94 Hall Effect Switch (HES) High voltage
31, is the crank sensor plugged in? if so duff crank sensor, i'd say all the others are concerned with the plugs being disconnected and re-connected, with the ignition on.

which is the crank sensor?
Don't forget if you flashed the codes out with the engine not running you always get code 31.
Check the wiring on the lambda sensor for code 66
Check AFM wiring for code 73
and check wiring to the little 3 pin plug ontop of the dizzy and to the coil for 94
crank sensor is on the front of the block, next to the front engine mount, held on by a 10mm bolt ;)

This is a new article added to a blank, in UBB visual editor, add and modify content of the article.
Wtf??
When I investigated the hall effect switch on Max boost it was something to do with ABS warning IIRC
Hall effect sensor is inside the dizzy
Had a feeling I was going to get owned on that one
