- FOUND:Concern verified found P2a01 02 sensor circuit range/performance b1 s2 P2a04 02snesor circuit range /performance b2 s2 suspect from bad o2 sensor, proceed to test the sensors, 02 sensor were pulled and tested over the bench, passes resistance test in the heater element and frequency test passes. however found a failure in the zircon element from the o2 sensor located at Bank 2 sensor 2. when the car its cold the readings are normal, but after test drive found the sensor readings very close to 0V (confirn reading of the o2 sensor doing a enrichment test and the o2 sensor react to the change in the air fuel mix) found worn out o2 sensor. because the o2 sensor are made from the same components, material and installed at the same time from factory we suggest remove and replace both o2 sensors. at the moment of the test only 1 o2 sensor was confirmed bad.
