What does ” open loop fault ” mean in fuel system?
The goal of the processor is to protect the catalytic converter with the best possible fuel system strategy. And finally, there’s “open loop fault,” generated for lean or rich codes. The processor thinks that there is an issue with both upstream oxygen sensors. The system will respond by going into open loop and providing no fuel trim correction.
