I had a chat with Blister at the last G2G regarding the MAF sensor:
The gist of the conversation ran as follow:
Mcnoogle wrote:...basically his mechanic did a test, replacing Blisters MAF sensor with the sensor from his own colt bakkie, and put the one he removed in his own bakkie, result - Blisters Pajero was all of a sudden, a lot more powerful, while the bakkie decreased in power, and increased in fuel consumption.
Yet, according to the Pajeros computer, there were no warning lights or anything to suggest that the MAF sensor isn't working properly.
Now I'm also a member of the "20l/100km club" and am also of the impression that this could be that my MAF sensor is faulty.Blister wrote:Sorry coming so late into the thread but yes I am convinced that the mechanic is correct that something is the matter with it which contributes to me belonging to the infamous "20l/100km club" besides wasting power
I spoke to my mackie yesterday, and he said a diagnostic will show if the MAF is faulty.
But how effective is that, - Blister, surely your mackie would have done a diagnostics check before swapping it with his,
did he swap them because the diagnostic test did not pick anything up?
Also from what he said, one cannot further calibrate the MAF sensor unless you have a chip, and that one needs to be careful about swapping MAF sensors, as you could melt your engine.
Colin, your explanations were very insightful as to how it works, but surely if loss of power/increase if fuel consumption would point to a dirty if not faulty sensor, and surely a diagnostic would pick this up.
Blister just needs to confirm if a diagnostic was done, and what the result was.
What we need to know is, has anyone else been through this process, regarding a 'underperforming' MAF sensor.
How does one go about cleaning / reconditioning it, or do you just replace it outright.
What has fixed this problem, i.e. what is the best and most cost effective solution?
