same here had to buy a new sensor for the driver's side, its currently being installed as we speak. Yesterday the car shut off on me while i was driving, alot more fuel consumption, engine dragging a bit, and those same lights came on as well. So I just parked it in the garage and called it a night, the sensor cost me 132 with taxes at the dealership!

 

I changed out both just to avoid future problems and the shop that did it didnt charge me extra to install. so it was 110 for both sensors
