My daughter just was given a 2009 Corolla LE with a 1.8l and it has some issues. ABS and CEL light are on, as well as the VSC and emergency brake light. OBD2 scanner posted both driver and passenger front speed sensors as being bad, replaced both and also threw a P0500 code and I replaced the speed sensor on top of the tranny housing. Took it for spin and threw all the same codes and dummy lights. I thought there were two speed sensors on the tranny housing but everywhere I searched it shows just one. Didn't there used to be a output shaft sensor with a small plastic gear that slid into the case? I'm at my wits end, she is about to get her permit and I can't even get the thing inspected because of the codes/CEL light. Thoughts?
