bank 1 is always the head with the number 1 spark plug and the number 1 sensor is always in front of the converters closest to the motor
P0133
Trouble code P0133 means:O2 sensor circuit slow responce (Bank 1 Sensor 1)
Replace the O2 sensor. Bank 1 sensor 1 means it is the sensor on the side of the number 1 cylinder and before the catalytic converter.
Bank 1 sensor 1 slow response.
Trouble code P0133 means: HO2S-11 (Bank 1 Sensor 1) Slow Response
O2 Sensor Circuit Slow Response (Bank 1 Sensor 1)
For 1996 and newer Trouble code P0133 means:O2 sensor circuit slow response (bank 1 sensor 1) Bank 1 = Exhaust side with #1 cylinder Sensor 1 = Sensor before catalytic converter
What P0133
P0133 Means the Bank1 Sensor 1 oxygen sensor is not communicating correctly with the computer, weather the sensor is failing, or there is an issue with the wire/connection from the main harness to the the sensor lead itself. usually replacing the oxygen sensor (this one is located just off the engine in the exhaust manifold) will resolve the issue.
Bank 1 is the bank of cylinders containing cylinder 1, which varies from engine to engine among the many V6, V8, & Boxer engines. Sensor 1 is always the "upstream" or Pre catalyst sensor. On most four cylinder or other inline engine configurations, there is only one bank. Sensor 2 would be downstream or after the catalytic converter. Diagnostic Trouble Code (DTC) p0133 refers to Bank1, Sensor1 being slow to respond. This may point to a failing sensor, or simply an intake or exhaust leak. Any gas leak can lead to unmeterd Oxygen in the system. This code may also be caused by fault wiring or connection on the sensor circuit.
There is a special socket wrench needed to remove it. Some auto parts stores have a loan a tool program so you don't need to buy it. P0133 indicates bank 1 sensor 1, that is the first oxygen sensor on the side of the engine with the number 1 cylinder.
Trouble code P0133 means: O2 sensor circuit,slow response (bank 1,sensor 1)
