Hi all,
Seems my XR is over fueling and causing her to hesitate when accelerating.
Local mechanic reckons I need to change my engine management temperature sensor.Is this another name for the coolant temperature sensor.? And if so where would I find it.?
In fact does anyone know what sensors are doing what.? I would love to find a list of each sensor and a map as to where they are located.?
I have no clue about EFI.
Thanks a mill.

or try same thing with coolant senor witch is under pipe that conecct thermostat housing and radiator

right one one picture

 

Thanks for the reply.
i understood the coolant sensor is the one that sits downwards into the thermostat housing close to the coil pack.? has a size 25 spanner fitting and is clearly visible once you pull the bonnet..
Is there two.? Is the one in your photo not the cooling fan switch.?

 

uh yes im sorry
You are right...on pipe is fan switch
under thermostat housing there is sensor (I think that one for dash) indicator)
but on top od thermostat housing is sensor (for ECU)

Im not shore witcih is witch now but if you dissconecct one and indicator on dashboard fell down other one is for ecu

ther is also IAT sensor for intake air temperature and that one is on rear of intake
