Hey John long time, no posts. Good to see you hanging around these parts again!!

I am finding that a lot of snorkel installers are using the building type silicone sealers.
This will coat the hot wires and give you a false reading. The gas as it dries out.
So, consumers beware of this and make sure they use an auto sealant when they fit your snorkel.

Very true John, you/they need to use Sensor Safe sealant, otherwise your up for new sensors or a poor running machine. Nice pick up.

Will maf cleaner fix it or will it be too late ?

Where is the sensor

Have a look on the previous pages mate

here are before and after shots of the diagnostic data, no real change but throttle response does seem better..


before


after

If you are talking diagnostics, well, the range for the MAF sensor should be 5 to 12 gms. This is at normal idle and not cold start.
Ye, sometimes I just can't spread myself around, when I get busy.
My customer vehicles must come first.
Yes, you can get the hot wires clean from that gas coating, with a good MAF sensor cleaner.
This is, most of the time. CRC is the brand that I use.
Catch you later, John.

I can confirm this sensor is the same for the 2.7 gas engine as well. Does anyone know what size the O ring needs to be? Mine broke when I lasted cleaned the sensor and I temporarily held it in place with sensor safe silicone

Sensors look the same but they are different.

Wow, that is interesting! They look exactly the same... What makes them different?

Different internals

Hi Techs,I have checked my techstream data and it im pretty sure my Sensor out of spec.Cold(40 deg) its like 8.9gm and when hot(84 degit pushing like 17 to18 gm.I have am lucky to get 550km before the lights on.
Cleaned egr/map,maf,changed fuel filters/oil/air.serviced every 5000kms.Injectors are in spec nothing over +- 1.Intake needs a clean but what else is to look for

Hey man if you have a read of this thread viewtopic.php?f=13&t=20254 you'll find everything you need to know.

Yeh I see that mate and what it looks like
I mean physically under the bonnet where is it located

On the air filter housing 2 screws 1 plug.
Don't touch it.
Maf sensor cleaner only.

Location, location, location.
The Roo.

Cheers all
She's expensive gear $32 a can
Good news is mine looked fairly good prior to a good spray
MAP filter however was a bit filthy
Put two cans of EGR 4 through the throttle body plenty of shit come out the back
Just waiting on my provent 200 to turn up now

cleaned my MAFsensor and my MAP Filter today, nothing to mention regarding the MAF sensor after cleaning but plenty of gunk came out of the Filter.

mine ticked over 100,000kms just after cleaning it today and can notice a slight improvment in the utes desire to get up and moving.


are these parts ment to be replaced after a certain time period or just when cracked or faulty?

Apparently Toyota don't change fuel filters at scheduled services
I changed mine yesterday and removed the filter housing to clean the jellyfish out of it
Swear to god I gained 20 horsepower
