im throwing a P0032 - H02S Heater Control Circuit High (bank 1 sensor 1)
error code

any ideas ??

sorted: Means my front 02 / AFR sensor is gawwn

would these codes be applicable to a 06 2.0i?

are they still making 2.0 ltrs in 06?

such is brake dust

yah... mines a 2.0i
then there is the 2.0r

then the RV which has a 2.0 aswell i think..

then the wrx and the sti have 2.5's

Its OBD2 isnt it? Only thing thats changed is that its a hitachi ecu compared to the denso from 01-05.

Just wondering if anyone NOR has one of the obd2 readers? I've plantedtge motor back in te car an I'm getting a CEL and would just like to see what it is.

yep send me a PM
