Check engine is on with TRAC OFF and VSC. I checked with OBD-II. It showed P0136 refer to Bank 1 Sensor 2. But at the same time I see voltage only on B1S2. Other o2 sensors without any voltage. What can you suggest? I replaced B2S1 front upstream, but no voltage through OBD-II.

I had a Prius it was difficult to repair and expensive. I had to take it to the dealership just to have the oil changed due to it being a hybrid.

I bought Toyota Sienna 2003 XLE which was transferred from 1st dealer to 3rd dealer then the 3rd dealer claimed the current odometer is reading 100,420 mileage which actually display on the dashboard unfortunately I was searching for something else 2 weeks later after the car was bought. I found 2 reassignment dealer titles stated that odometer are 184,787 and 185,126 mileage with the same VIN number written on the documents respectively from the 1st and 2nd dealers. Can someone tell me if odometer was rollback or what?
