is the o2 sensor (connector color) on the driver side blue or green? would it matter? SEL keeps coming on after the know it all tech's at the dealer messed with them. they put the blue on the driver side and green on the passenger side. i saw a pic with green on the driver side and blue on the passanger.

Green is on the Drivers Side and Blue is on the Passenger side.... I dont think it would change anything because they are both the same kind of sensor.... if you had the top and bottom sensors reversed then it would possibly cause problems but I dont think you should be having problems though.... hell just try switching them ... it would take you 15 min at the most....
