o2 and MAF Sensors

Postby Protok » Tue Jun 30, 2015 4:11 pm

Currently got error codes for one of the o2 sensors and the MAF sensor.
So I went to Toyota for a quote and then immediately walked out :roll:
£121.81 each for o2 sensors and £145.11 for the MAF sensor.

Is there anything available after-market? I'd rather not buy second hand cause in previous experience, it was false economy and blueprint stuff is cheap but reliable enough normally.

for o2 sensors, they come in generic (you solder them yourself) or pre-wired flavours. plenty of places do them, not sure on specific one for altezza but have a good.

maf sensor.. toyota or denso, both similarly priced new.

pm Nick from the traders section of the forum, he will likely give you the best price you can get for a new MAF.

alternatively, clean your maf with MAF cleaner as that has worked for a lot of people.

i had errors on o2, maf, idle control and throttle that were all cured by replacing coil packs btw

Do you have a part number?
I popped into a local A-Z and they just had the IS200 which I am not sure if they are compatible or not.

Anyone got the part number for the Denso one?

I like Nick's deals but for something this small, it would probably cost too much in postage to make it worthwhile.

I've been told that cleaning it won't have the same result as replacing it, the huge flat spot and lack of response is getting a bit stupid now.

Coil packs are all brand new so wouldn't be that; my idle control is pretty much perfect anyway.

Have a google, there's discussion on which you'll need depending on auto/manual. DOX-0109 might work. google!

the denso and toyota maf sensors are the same price.

they will still be like £100, but either way I'd check with nick.

clean the maf and find out. it takes 15 minutes.

I got a universal denso o2 sensor for 50 quid I think. It's always come up with heater circuit malfunction but works fine so I just ignored it. Dunno if that's from my wiring or what. The Hester wires are both black so no idea which is positive and negative which may be where I went wrong
