The map sensor is above the air filter, which is the left as you look at the front of the van. If you follow the bonnet hinge towards the wing you will see attached a bracket with a black plastic box with a small vacuum hose attached. There is a plug also attached to the black box ( MAP sensor ). This plug has three wires going into the plug. Back probe the centre wire of the plug ( +ve lead of multimeter ) and -ve lead to earth.
With the ignition turned on only it should read near to 5V. Start the engine up and you should see this value drop to 0.8V - 1.22V at idle. Rev the van up and see what values you get ( mine sometimes drops below 0.3V when engine comes back to idle. Note all my tests have be done with a cold engine.
Hope you can understand the above. Interesting to see your results.
Cheers
