LinkG4 98 WRX - Air temp sensor query

[James Mowat]

Hi All

Putting my car back together after a year off the track due to engine fail,

the car is running but,

Running the Expansion connector

An Temp 3 is seeing 100c

Same with sensor unplugged,

Same with extension wire removed

Voltage meter across Green/GND & Orange/Temp 3 - 4.96v

Voltage meter on the wires from the IAT sensor - 0.17 (10c or less out side)

-------------

What am i suppose to be seeing across GND & TEMP3

-------

I have An Temp 2 turned off due to reading -40c (sensor in the Maf has failed, but u have never used this input, always used An Temp 3)

 

Cheers

James

Itchn to run this motor in

Also another Q

the new sensor i am running is the same one thats on the IAT sensors page on the link web site

for this sensor what should be selecting

STD Bosch NTC?

 

Thanks

That will most likely be using the Delphi AC IAT cal assuming it is the same sensor.

With no sensor plugged in to the temp channel you should see close to 5V

With sensor plugged in this should be much lower and will vary depending on temp.

Check the fault settings in the AN inputs menu (at the bottom)

Thanks very much Simon,

had a 15 min window of time in the shed, armed with above info, confirm the sensor worked,

 

it was one of the female crimp connectors, out hadn't latched in the plug and was pushed backwards/ out

sorted that, all reading properly now

thanks again
