robrado974 1 Posted November 21, 2013 I was looking at the manual ,trying to sort my starting problems as i had a reply about the blue sender being linked to the ecu . I was looking at the sender housing and saw that the third hole should be a plug . It states that a sender should replace the plug with vehicles that have air con . Why do i and another vr that i saw this week have a sender and not a plug when we dont have air con ?. Rob Quote Share this post Link to post Share on other sites
Jim Bowen 1 Posted November 22, 2013 Mine has a sensor and no aircon, but i removed the aircon and left the sensor in, doesn't seem to change anything that i've noticed. Quote Share this post Link to post Share on other sites
GusPW 0 Posted November 22, 2013 Isn't the 3rd sensor the black one for stage 3 fan? Maybe the American AAA engine had a different arrangement. Our maybe it's based on early vr6 with 2 stage fan set up. Quote Share this post Link to post Share on other sites
VR6 Gar 10 Posted November 22, 2013 My old K reg had 3 as does my L reg. Neither had aircon. Yellow, blue and black, not necessarily in that order though. Quote Share this post Link to post Share on other sites
