So I did all the new sensors and the MAF then over the weekend the SES light came on again and the codes I get this time are P0103, P1415 and P1885... once again your help is appreciated. As a quick thought could these codes come from a shorted ground connection? I noticed when I unhooked the battery to make the sensor repairs the negative terminal connection was loose and I tightened it but it was still not super tight.
