We've got a 2010 F-550 4x4 that the high idle no longer works on. Everything worked fine when we installed it, however recently it will not work - the only thing we can find is we have a P0546 code for Exhaust Gas Temperature Sensor Circuit High Bank 1 Sensor 1. We have power everywhere we are supposed to, but the ECM is not grounding the PTO circuit to turn on the high-idle...

Would this code/sensor problem cause the high idle to not work for any reason?
 
Just in case it ever comes up again - YES, this code can cause the computer to not "idle-up" the engine.

Replaced the sensor and all is ok :)
