Fuel Mapping Sensor

Post by 9of9 » Tue May 21, 2013 8:57 pm

Hi
I have an engine warning light on the dash, I have had it to the mechanic and he tells me I need a new fuel mapping sensor, apparently they are not available in NZ, does anyone know any different?

It would help if you told us what year/model of car you have. To the best of my knowledge there is no fuel mapping sensor on the NA or NB MX5.

Either that or the knock sensor. Neither of which should be difficult to obtain.

A fuel mapping sensor...
Try taking it to a mazda mechanic would be my advice
Or just go to a mazda dealer

Could just be the Air Flow Meter but thats the closest thing to a fuel mapping sensor on any NA/NB and the car won't start if this isn't working

Only other option I can think of is the Evap canister relay but I removed mine and didn't throw any codes
Try remove the evap canister and loop the lines I can send you some pics of how to do it or just google it and there are hundreds of how to's on it

Try disconnecting this sensor and see if it still throws a CEL (the one behind the coolant tank)

Got it!!!
The fault code was P0107, which for most cars is "Manifold Absolute Pressure/Barometric Pressure Circuit Low Input". However, for the MX5 it's a fault in the EGR boost sensor.

Not the first time i've heard of that fault,Had Auto sparkys ring from time to time for them,Not all NB's have it either,only the last of the late NB's that met emission rules from a couple of years ago.
If you get stuck,find the part number on it and contact me at work(Mazline),Might be able to find one

Thanks for the offer Brownie. I believe a new one has been ordered from Japan.

Always better to go new,being they are prone to faulting,used ones always going to be a 50/50 call as to how long it will last
