vr6storm 0 Posted March 3, 2006 IIRC the yellow one is the guage sensor and the black one is for the ECU.....if that has gone you'll experience cr4p running/starting Share this post Link to post Share on other sites

REMUS 0 Posted March 4, 2006 Yep. Black is for the ECU and allows you to read your coolant on the MFA. Share this post Link to post Share on other sites
