Posts: 261 Thanks: 17 Trader Rating: 0 ![]() | P0133 Oxygen Sensor Circuit Slow Response (Bank1, Sensor1) A week into owning the Bravo and having problems already :shout: basically, the CEL flagged up yesterday while driving although no other issues (loss of power, poor idle etc) Read it today and got P0133 Oxygen Sensor Circuit Slow Response (Bank1, Sensor1) after a quick google this can be caused by anything from a bad sensor to exhaust leak to EGR apparently, Looking through the history on the car it had the sensor changed back in Dec 14 and when I picked the car up last week it to get CEL reset for the o2 sensor Think its worth changing again and would it make a difference whether its OEM or Euro Car Parts as I know cars can get fussy about what gets used, or digging about more ??
