p0133, b1s1 o2 sensor
Am I correct in assuming that the B1S1 O2 sensor is the one before the cat on the driver's side? P0133 means "slow response from B1S1 O2 sensor". Has anyone tried simply swapping the B1S1 and B2S2 (post cat) sensors? It seems like if the sensor isn't totally dead, swapping them may alleviate the problem for a while. The pre-cat sensor is used to adjust the fuel trim, the post-cat is used to simply monitor the cat efficiency, correct?
The freeze-frame data shows the bank 1 short term fuel trim at +32.8% and long term near 0%, which is indicative of a temporary low voltage from the sensor. If the sensor dies completely, the long term trim will creep up to a high value and you'll get to stop at the gas station about once every 10 miles or so. I've had that problem before...
