If you have a short piece of wire you can bridge the two connectors in the
temp II plug and this will allow the van to run well.  It will run a little
crappy and you will have to hold your foot on the pedal when it is cold but
once it warms up (just a few minutes) it will run like normal.  I was taught
this by Darrel Boehler on a trip a couple of years ago.  Worked like a charm
in my 89 Wolfsburg.  You have to be careful in the 1.9l Vanagons though.  I
have found that many of them have a problem that seems like faulty temp II
but it is actually the wire going from the computer to the Temp II that has
become faulty.  It gets a high resistance and then no matter how many
sensors you put in, the van will still not start when hot, run rich when
warm.  Also a faulty or non-existant ground strap to the engine can cause a
high resistance reading.  Checking these with an Ohm meter takes a Bentley
manual and about five minutes of time.  People think I am a miracle worker
when I can diagnose their van after everyone else has given up on it.  I
tell all my customers that I have a better survival rate than any doctor.  I
have never lost a patient!  :-)  95% of the time they could have diagnosed
it themselves with a little patience, a Bentley and an Ohm meter, but don't
tell them that :-)

Assuming I do not carry a spare temp-2 and I have this failure far from
home... would one of these be the correct work-around to get a hot engine to
start and not run rich:

1) Disconnect the Temp-2 sensor?

or

2) Disconnect and connect the 2 leads (are there 2 leads?) together?

or

3) Disconnect and ground the 1 lead (is there just 1 lead?)?

or

4) Other or no work-around?
