Fault codes

[Bernie Benz]

Mike, 
I doubt that the IM thermistor is actually bad, rather a false code
associated with other problems.  BTDT.  As I recall, somewhere in Bentley is
the resistance vs. temp data for all the various thermistor temp sensors,
allowing you to check the unit with an ohmeter.
