I had a look for this MAF sensor everywhere and I cant find it, not even in the au's service and repair manual

Peter,

You have a downright nasty persistent problem. I am sorry that we have at this stage been unable to help you get it sorted.

Hang in there, you'll get it sorted, just a matter of time and remaining persistent.

thats the one,
i feel for you mate theres nothin worse than prob that you can't fix ,its all trial and error .the downside is it all cost money .
i dunno ,maybe take it to a reptuable shop and get them to plug in the old scan tool and see what the sensors are doing and try and get a straight answer.

could the throttle body cleaner have damaged your map sensor?

PeterAU · 12-01-2007, 08:26 PM

reseting has helped a lot it is smooth now with just a little shake, I'm going to take the map sensor out for a clean in the next couple of days ( the throttle body cleaner says it does not hurt sensors) thank you for all your help

Actually, 6's have a t-map sensor and it's located in the inlet manifold, under the TB. Bugger of a thing to get to. E series cars had the map sensor on the firewall, IIRC.

Thanks for that I thought I was going mad because I couldnt find it lol

Do not use carb cleaner to clean a throttle body, use throttle body cleaner only. Throttle body's have a factory installed coating(most of them) that will be washed off be with the more caustic carb cleaner, this will/may cause the throttle butterfly(s) to stick most likely causing a rather high idle condition necessitating the purchase of a rather expensive throttle body.

Since the early 90's they have come out with throttle body cleaners that WILL NOT hurt the Teflon coating on the throttle body. (DO NOT USE CARBURETOR CLEANER OR THIS "MAY" DESTROY THE TEFLON COATING!)

Thanks for that warning.

Here is the product I used. I guess it would be ok, as it's marketed as a Throttle Body and Carby Cleaner, not simply Carby Cleaner. Everyone can check it out and decide for themselves whether it's safe to use or not.

http://www.nulon.com.au/products.php?productId=carb400#

Here are the directions for use, taken from the website, but I posted them here anyway. Note that if used as per recommendations, it won't do any sensor damage.Directions: It also recommends throttle body cleaning to manuafacturer's specs. See what you think anyway people!

The aerosol can in which Nulon Throttle Body and Carby Cleaner is supplied provides full and accurate directions on how to use the product in all of the following applications:

1) Vehicles with Carburettors

Carby exterior and linkages
Carby throttle and combustion chamber deposits
Automatic choke
PCV valve
2) Vehicles with Fuel Injection

Throttle body
Combustion chamber deposits
Note 1: When used as per the directions on the can Nulon Throttle Body and Carby Cleaner will not harm oxygen sensors or catalytic converters.

Note 2: If sprayed on car paint wash off immediately. This product may cause paint damage.

Note 3: Follow vehicle manufacturer's directions when cleaning throttle bodies fitted with electronic throttle control.
Important:

Do not allow cleaner to contact paint work or plastic
Do not puncture, incinerate or store above 50°C
Do not place can in direct sunlight or near heat or flame
Use product with adequate ventilation – avoid prolonged or repeated breathing of vapours and avoid prolonged or repeated contact with skin or eyes

GK there is a loom that connects under the TB onto the intake manifold, that is the T-MAP

Is it about the size of a cigarette packet? Maybe slightly larger?

It looks hard to get at, if it's where I think it is!

I'll grab a photo for you shortly... and yes very hard to get to

TMAP Sensor: From the outside & from the inside of the intake.

I have just sprayed the black protusion with throttle body cleaner and taken the car for a 30km drive mixed hwy / suburbia. It has already dropped 1.8 L/100Km and I haven't even reset the ECU yet.

Outside of intake
Inside of intake
