Seems to be a recurring theme on these forums.
Anyway, I've posted a couple of times before RE my faulty MAF sensor.
This is a facelift Micra with the Bosch TB - not the one that can be re-soldered.
The original MAF got so bad, I couldn't get past a few MPH - unplugged it for a short trip and everything went back to normal.
Bought a replacement MAF on ebay for ~£27. Not very good - poor MPG (mid 30's instead of previous mid 40's), hesitation, hesitation through the gears and poor high speed performance. Occasionally cuts out when the revs drop too low (turning off electrics and coming up to junctions). Has also given me the code P0100 (MAF circuit malfunction).
Got another MAF sent out from the same seller. This one fixes most of the above problems, but still with poor high speed performance and a new problem of kangarooing! Violently jerks under acceleration! Because of this I've reverted back to the first replacement sensor I received.
My questions:
1) Why would the Haynes manual say this sensor is not replaceable, and that you must replace the whole TB as a unit
2) I've been thinking of the possibility that it could be something else causing the problem, but I'm put against this idea because the car performs fine with a sensor unplugged, and each sensor I am trying has it's own characteristics - making it (to me) more likely to be the sensor itself at fault.
3) Do you have to reset anything when you replace the sensor. I've been scouring the Internet - some people believing you have to unplug the battery for about 24 hours, others saying it wouldn't make any difference...
I've just been swapping them out without following any of these supposed reset methods.
I must just be really unlucky with these replacement sensors I'm trying. It's so frustrating that Nissan or Bosch can't supply the genuine part - without the rest of the TB at a cost of about £450!!
Any advice / guidance / answers will be greatly appreciated!
Thanks!
