P22B2: Your Car’s Fuel System Needs Attention
The P22B2 fault code is related to the oxygen sensor in a vehicle. This sensor is connected to the Smart Oxygen Sensor Module, which receives information from the primary Powertrain Control Module via the J1939 BUS.
The Smart O2 Module performs its own diagnostics and reports failures back to the primary engine PCM using the J1939 BUS. If the PCM receives an FMI message from the Smart O2 Module, it will set the Diagnostic Trouble Code (DTC) P22B2, indicating an issue with the O2 Sensor Bank 1 Sensor 2 Return Circuit O.
FAQ
If you see the engine light on or the service engine soon warning light, it could be due to the P22B2 fault code. This code is usually caused by a faulty O2 sensor in Bank 1 Sensor 2, an open or shorted O2 sensor harness, a poor electrical connection in the O2 sensor circuit, or a faulty Smart Oxygen Sensor Module. To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light due to a P22B2 fault code, there are a few possible causes to consider. One of them is a faulty O2 Sensor Bank 1 Sensor 2, which can be fixed by visually inspecting the related wiring harness and connectors.
