thats great many thanks. Any ideas how I test to see which sensor is busted. Is there a resistance specification for the working sensors, or should i just bridge out each sensor until the problem goes away? Just trying to save my retired father buying three sensors when only one maybe busted?

The diagnostics on these old buses is as useful as a wet paper bag in a hurricane. The sensors are simple thermistor devices. If you pull them out you might get a part number for them. If so they would only be pennies to replace.
