What to do if Bank 1 sensor malfunctions?
Remember that bank 1 refers to the side of the engine with the #1 cylinder, no matter what the vehicle or engine type. If the electrical connections are all sound, then replacing the oxygen sensor will typically solve the problem. If water is discovered in the connector, then replace the fuse to the heater circuit.
What does it mean when Bank 1 oxygen sensor is not working?
Oxygen sensors allow the ECM to determine the amount of oxygen in the car’s exhaust stream. A code P0136 gets set when on-board diagnostics detects a malfunction with the O2 sensor behind the catalytic converter on bank 1. Code P0136 means that the Bank 1 oxygen sensor is not operating correctly.
What causes an OBD-2 sensor to malfunction?
Loose terminals in the connector Open or short in the wiring due to rubbing on engine components Holes in exhaust allowing unmetered oxygen into exhaust system Unmetered vacuum leak at the engine Using a scan tool, determine if the Bank 1, sensor 1 is switching properly. It should switch rapidly between rich and lean, evenly. 1.
What is the DTC for O2 sensor malfunction?
P0136 is a diagnostic trouble code (DTC) for “O2 Sensor Circuit Malfunction (Bank 1, Sensor 2)”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic.
What is O2 sensor circuit for bank 1 sensor 2?
The O2 sensor circuit for bank 1 sensor 2 is used to give a voltage feedback to the ECM to control the fuel and provide information about catalyst operation. Need help with a P0136 code?

How to tell if Bank 1, sensor 1 is switching properly?
Unmetered vacuum leak at the engine Using a scan tool, determine if the Bank 1, sensor 1 is switching properly. It should switch rapidly between rich and lean, evenly. 1. If it does, the problem is likely intermittent and you should examine the wiring for any visible damage.
