I have a Ford Fusion 2 2003, The engine warning light has appeared, I placed a read on to see what the fault was and it gave P0030 H02S BANK 1 SENSOR 1 HEATER CIRCUIT. I went it a local parts shop and told them the error message, They said it was a senor on the exhaust?? I then paid 56 for this sensor that i thought it was, Placed the sensor on ( was on very bottom on the engine connecting to the exhaust after the cat i think ) and the warning light is still on.

However when i thought id check what the spark plugs conditions was in, when removing the black cover from the engine i saw a senor on top / backend of the engine is that looked the same but with a different connection plug.

Can anyone tell me where this sensor bank 1 sensor 1 heater circuit is please? i have tried googleing pics of where it is with no luck at all.

Thank you in advanced.
