CL = Closed loop using HO2S(s) as feedback for fuel control. OL DRIVE = Open loop due to driving conditions (heavy acceleration). OL FAULT = Open loop due to fault with all upstream HO2S sensors. CL FAULT = Closed loop fuel control, but fault with one upstream HO2S sensor on dual bank vehicles. |

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
