F2-39

Hello

I've got this code on a mx2700. The manual says it's the process thermistor which has a problem, connection/harness maybe. Is this the thermistor on the lsu?

Thanks

Bill

Nope the lsu thermistor is F2-49, this is the thermistor in the bypass tray

F2-39 does relate to the sensors in the bypass. Go into sim 44-16. blow into the area on the bypass that has the holes to let the air in. Look at the values in sim 44-16 for temp and humidity. They should change as you blow into the holes. If they do not them measure the voltage at the pcu pwb for the temp and humidity. If they change as you blow into the holes the sensor is good and you pcu is bad. If the voltages do not change the senos in the bypass is bad or the wiring between the senso and the pcu is bad.

Thanks for the info. I changed the thermistor and so far no repeat.
