I wonder if anyone knows the meaning of this code that came up under historic trouble code "21B6 Preparatory Codes"
As the car is de-catted the check light normally comes on and on a select monitor reports error on bank 1 sensor.Once reset all is O.K

Is this the same code that the select monitor reads.

(STi7 Type U.K)

Thanks.

Grant,

You could mail Stephen Done and ask him as I can't even find it in DeltaDash's fault code lists....

Matt :)
