The first sensor in Bank 1 is located closest to the engine and is known as Bank 1 Sensor 1. It’s on the engine side, with cylinders 1, 3, 5, 7, etc., on bank 1. The Bank 1 Sensor 2 is located behind the catalytic converter on the engine’s exhaust pipe. The cylinders 1, 3, 5, 7, etc., are located on the engine side, which is referred to as “on Bank 1.”
What causes a bank 1 sensor 1 code?
Problems in bank 1 sensor 1 oxygen sensor or its circuit cause the P0130 fault code to appear on the dash of your car. If the PCM detects a potential problem with the oxygen sensor voltage (or air-fuel ratio sensor) or its circuit, the code P0130 will be displayed.
Should I replace both oxygen sensors at the same time?
What if I only need to replace one sensor? When replacing O2 sensors, it is preferable to do so in pairs. If you replace the downstream left sensor, you should also replace the downstream right.
Is bank 1 before or after the catalytic converter?
The Bank and the SensorBank 1 Sensor 2 is the second sensor on the exhaust pipe, usually behind the catalytic converter, in the exhaust system.
Is there a fuse for oxygen sensor?
Yes, the o2 heaters have a fuse. Make sure all the fuses are in working order. Checking the harness is also necessary in case it’s the cause of the problem.
Where is the o2 sensor heater located?
A Heated Oxygen Sensor sits in front of the exhaust system. Oxygen Sensor Heater includes this component. There is a Heated Oxygen Sensor located behind the cylinder head.
Can I change my own oxygen sensor?
The replacement of an oxygen sensor is usually a straightforward process requiring only a few common hand tools. A professional mechanic, like one from YourMechanic, can take care of this for you quickly and easily if you aren’t confident in your ability to do it yourself.
