P1086 Fault Code: Understanding The Description And Troubleshooting Steps
The P1086 fault code indicates that the fuel control mixture in Bank 2 of the engine is too rich. This means that there is an excess of fuel in the air-fuel mixture, which can negatively impact the engine’s performance and fuel efficiency. The ideal air-fuel ratio for a gasoline engine is 14.7:1, but different operating conditions may require adjustments.
During full-throttle operation, a rich mixture is needed for maximum power output. However, if the air-fuel mixture becomes too rich, with a lambda value less than 1, it can lead to inefficient combustion and reduced power. In the case of the P1086 fault code, Bank 2 of the engine is experiencing this rich mixture condition.
This could be caused by a variety of factors, such as a malfunctioning oxygen sensor, a clogged fuel injector, or a problem with the fuel pressure regulator. To fix this issue, it is important to diagnose the specific cause of the rich mixture in Bank 2.
This may involve inspecting and testing the oxygen sensor, fuel injectors, and fuel pressure regulator.
Once the faulty component is identified, it can be repaired or replaced to restore the proper air-fuel ratio and improve the engine’s performance and fuel efficiency.
FAQ
If you’re seeing the engine light on or the service engine soon warning light, the fault code P1086 could be the culprit.
