Should an MAF sensor look like this ??

Postby impartialise » Thu Aug 05, 2010 4:01 pm

Right, so I took my MAF out for cleaning last night, and this is what I found;-

Firstly the rubber seal was missing
There are pieces of plastic that look like they've broken off (hope these didn't end up in the cylinders! )
And it appears to be missing the thermistor (temp sensor) and looks like it has been 'repaired' by soldering the two metal legs together.

I can fix the seal, that's no problem. What about the missing piece of plastic, do you reckon it needs to be there to direct airflow ??
As for the thermistor, I was thinking of buying one of those '20bhp chips' - actually a resistor which replaces the signal for air temp to ECU - selling on ebay for 99p to bypass this temp probe, as currently there is no resistance.

Strangely the car seems fine to drive, even after cleaning it, the Tezza seems a little more perky, but I still think there is power missing and am thinking that this may be why.

Any thoughts or comments appreciated,
Cheers,
Phil

I'd get a complete replacement if it was my car , I know new ones ain't cheap but even a secondhand one from a scrapyard would be better than that butchered yoke ... :(

OK, I've been outvoted !!!

I just don't like to spend money wherever it's possible to avoid it !

I think 22204-21010 is the part number - METER S/A, INTAKE AIR FLOW - from TOYODIY.com

I'll bite the bullet and stop being so thrifty, with any luck it'll increae my MPG and I'll be saving money after all :D

Cheers for replies guys, helpful as always

You have to reset the ECU (disconnect battery or pull the correct fuses ) and it'll take a few days of driving for it the learn again ;)

I'm getting around 500-525 KM to a full tank.

I've heard others are getting 600+ and I'm not even heavy footed in normal driving moods.

Found a second hand one for £100, think it be just as well to buy new though for the sake of a few extra £££s

I'm by no means an expert, but if you cleaned the throttle body too, maybe there is a loose wire on your throttle position sensor, or the sensor itself is faulty or dislodged.

just a thought
