Title: What is this sensor?
Post by: Pearlmoto on March 02, 2017, 10:41:50 am

Trying to ID this sensor.  It's on the back right side of the A/C, wires are purple and yellow.

Motor is an LT9 5.7L

In the image the wires appear brown and yellow.  That is the air temperature switch for the Air Management System (http://www.73-87chevytrucks.com/techinfo/7387CKMans//Service/X8632_1986_GMC_Light_Duty_Truck_CK_G_P_10_to_30_Service_Manual.pdf#page=1033) used on heavy-duty emissions engines.

I'm not sure why it double posted like that, sorry fellas.

Yes I made a mistake, the wires are brown and yellow.

Thank you for the reply bd
