What is the sensor on the throttle body ? what does it do ( or i think in my case what SHOULD it do ) can i test it ?

The damn thing wouldn/t start this morning and when it did start eventually i decided to have a poke around and i unplugged this sensor and nowt happened ? i would have thought it would cause a surge splutter stall or at least something as it is connected to the throttle body so it must do summit ?

Also i still can't rev the engine for approx 1 minute after starting and i am clutching at all available straws.

I think it's for the air temperature Bart yes you can test the resistance across the 2 pins. It is different for different temps let us know what u get I have the specs a home or they are in the manual

what does it do ? more diesel,less diesel,tick over lift or drop or is it just another pointless effing sensor like the EGR just put there so it can fail and F everything up and make me swear and curse ?

@123hotchef , doesn't this sensor have something to do with Vacuum system ? if so could it be a vacuum leak somewhere that is preventing the truck from revving ? maybe @LezT might know ?

THrottle body has no sensor that I know of except air temp...

@bart any other symptoms..

it dont have anything to do with vacume it just senses the air temp and reports back to the ecu different resistances for different temps

The symptoms are still a pig t start at times (when cold ) and when it does start there is no response from the throttle pedal untill it has been ticking over for about 1 minute, then you can rev it and drive it. Once it is warmed up it drives ok apart from the point where you just press the accelerator where it feels like it is either struggling for fuel or air as it goes bbbbbbrum (tech speak) this is hot or cold,slightly better when hot.
The whole heater plug system has been tested and most of it is infact new. All voltages and resistances are spot on so it has nothing to do with the glow system.
When driving it goes as it should, turbo kicks in etc etc and only bad point is the hessitation at low rpm

HELP

whats the resistance on that sensor mate? i did ask the other day

do it mate simple 1 min job take plug off and test 2 pins

right soz mate there are 2 sensors right i want u to test the one on the right not the front one ok

i tested the 2 pin one that is at the front if you are facing the engine and the resistance is nil nada nowt !

now do the one on the right!

That has 3 pins which ones do i test ?

hum the book states to test the sensor itself is one a ground?
if so test the other too

no idea it's dark and -2....

what is that sensor ?

that sensor is the boost air temp

if you got infinite then the other one is fooked

is nil nada nowt infinite mate?

i just tested mine for comparison i got 1ohm

---

what should i be getting ?

no reading at all?

u must have got something on the multi meter

The meter didn't register anything not even 0.01 ohm ! Don't know if it is meant too or not ?
