Occasionally seeing the following fault code which light the CEL- usually goes off after a couple of stop/start cycles. Always occurs when I've just got on the motorway, never happened at any other time.

P0546 Exhaust gas temperature sensor circult high input

Its a MY03 import, MD304, STi Pinks, Warlbro and FSE, APS top mount, full de-cat including up-pipe, and a hyper-flow cold air kit.

Its running on a TEK3 mapped by Pat.

Any advice gratefully accepted
