Hi
Just had this fault code come up p1031, i've had both the pre-cat and post-cat sensors changed so it cant be anything to do with them.
Any ideas??
Cheers.

Edited - Ok i've found out what the fault code is - DTC P1031 HO2S Heater Current Monitor Control Circuit Banks 1 and 2 Sensor 1.
Any ideas what it is and how to cure it??
