Comments about Bosch Oxygen Sensor:

When the new O2 sensor was installed on the car it caused serious performance issues! Immediately after the part was put on the car would surge, almost all the power to the engine was lost and the car became undrivable. I lost a good deal of time and money to a part that wasn't correct. I know that the bad bad performance of the car was a direct result of the new o2 sensor as all of the following parts had been serviced or replaced: fuel injectors, pcv valve, spark plugs and wires, map sensor, and the throttle body. Before the o2 sensor was replaced, the car performed at top notch! It was because of a PO420 code that I had to replace the sensors. When I bought new sensors from Toyota and installed that there were no issues what so ever. This Bosch sensor was a waste of time and money!!!

      It is recommended to replace both the upstream and downstream oxygen sensors at the same time, the part number 13056 refers to the Downstream Sensor and the part number 13051 refers to the upstream sensor.
