Just looking around under the bonnet on my 4x4 sapphire I know it has greens in it and was wondering how to check if it has a three bar map sensor. The one fitted has a black base and a light grey top half? Just trying to sort on my 20ish miles to a tenner problem (and thats when taking it easy)

 

you have a3bar map sensor fitted IIRC. the fuel consumption may be down to a dodgy water temp sensor,thats what was eating all the petrol in mine.its the blue sensor back of the engine nr the dipstick.only £20 brand new!

 

cheers for the reply. Is there any way of testing the sensor or is it best just to drop a new one on?

 

im sure if you asked on here there is a way to test it,but for £20 i would just change it.its really easy its just a case of unscrewing the old out and screwing the new one in. you ve got to think if its never been changed its chance to be at least 16yr old

 

yes thats a 3 bar map sensor light grey 2 bar is black
