The sensors rarely go bad. What does fail is the connection. Most apparent
sensor failures are fixed by merely disconnecting and reconnecting the plug.
It is the same plug as the injectors. Replacing the contacts or the complete
connector can do wonders.

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?
