OK. Figured it out. Bulb in tester was out. Then contacts in car OBDII socket were not making good contact with scanner tool. Once I bent the contacts slightly, scanner tool worked. Got P2135 code. Ordered a new throttle body online. I figured I'd just replace the whole throttle body then just monkey with the sensors.
