Vector 1850 Suction Line Temp Issue

[swampy84]

Hi all. Have a suction line temp sensor reading -47 degrees, which is what it will read
for an open circuit. So I changed the sensor and still had -47. I then disconnected both the return air and suction line temp sensors and they were both getting 2.6VDC.
I then cut the wiring at the microprocessor and connected the suction line sensor directly
to wires 1MP19 & 1MP32. It is still coming up with -47 degrees lol.
I'm assuming its a micro, but just finding it hard to believe when there is an identical
voltage to that of the return air sensor which is reading fine.
Im not overlooking anything like a configuration error?
Any help appreciated

Do you not have another sensor say from another unit that works just to prove its not another faulty sensor?

[swampy84]

Yeh mate tried multiple sensors as I've got spares in my truck

[cadwaladr]

Have you got another micro to swap to eliminate prove the fault?

[swampy84]

Yeah mate I'll slap it in and see how it goes
Not confident though as the output voltage
Seems ok

[swampy84]

Just don't know what else it could be

[cadwaladr]

Micros work of the devil/dark side

[swampy84]

slapped in and configured a new micro and still no joy lol

[swampy84]

sorted it lol incase anyone cares )
