Also, will the aircon turn on with this missing? it isn't also looks like the ECU isn't getting a signal that the A/C has been turned on since the IACV does not re-adjust idle when pressed. It's a JDM RHD car with factory auto aircon

Basic info is missing here

Car, year make and model, and what are we looking at?

1992 Silvia K's RHD JDM

interior temp sensor for auto a/c unit.

Have you found it on a diagram? Is that what it's called?

Try looking up whatever the parts places have, evaporator temp sensor?

no idea what it's called

Looks like the skylines used the same sensor

Found it!

Thanks guys

Still don't know if this is preventing me from starting the A/C, ran the auto a/c self diagnosis and just came up with error 22 which pointed at this missing sensor and auto turns on heat since it thinks its -30 degrees C inside. not sure if this would over ride not turning on the A/C though

NISSAN part number

27720-01U00

the fitment into the bezel may not be correct but I just need it there reporting correct temps

anyone know a good wiring diagram or site for JDM cars i can review to figure this A/C crap out? Can't get the A/C clutch to turn on even after jumping the low pressure switch, and the ECU does not rev up when turning on the A/C

WEll after further digging around the interwebs it appears this is the culprit to my A/C Woes

"I don't know if this applies to anyone but in doing a ton of research on my wiring harness for my sr20det I found that it has an ambient air temp sensor input on the engine harness. With this working correctly it makes it so that if it is 45? or below it will not allow AC pump to kick on. So if you guys have one maybe the sensor is going out or is too close to the accumulator which gets damne cold) and turning it off? Just an idea."

tempted to just get a resistor and getting it to read always hotter than 8C inside. or find someone parting out a R32 I can cop this sensor from. All sources new are in Japan and don't want to wait that long for the damn sensor.

d1zguy2

eh for now I ordered some thermistor resistors after looking at pics of the sensor. It's just a fancy housing for one of these.



Will just plug this into the harness and stick it in the tube, luckily the air con unit allows me to view the temp it reads hope it's close to what it should be
