Possible causes for this code include:
- HO2S sensor failure: The HO2S sensor may be faulty or damaged and not able to properly detect changes in the oxygen in the exhaust gas.
- Wiring issues: There may be a problem with the wiring or connection to the HO2S sensor, such as a loose or damaged wire.
- Exhaust leak: An exhaust leak near the HO2S sensor can cause incorrect oxygen readings and affect sensor operation.
- Fuel injector problems: Malfunctioning fuel injectors can cause the air/fuel mixture to be incorrect, which can affect HO2S sensor readings.
- Engine mechanical issues: Problems with the engine, such as a vacuum leak or a faulty oxygen sensor, can also affect HO2S sensor operation.
It's important to note that this is just a general overview and the specific cause of the code may vary. It's recommended to have the vehicle inspected by a qualified technician to accurately diagnose and fix the problem.
