Если коротенько, то P1166 HO2S System — Lambda Controller at the Limit (Bank 1)
Description
1. General Description
The Lambda closed-loop control system is included in the engine’ s control system. The control system regulates the lambda upstream with the HO2S signal. Rich mixtures generate high concentrations of CO, H2, and HC. Lean mixtures generate the high concentrations of NOx, and free oxygen.
2. DTC Description
If the lambda controller reaches the maximum or minimum threshold, then feedback control is no longer possible and emissions will be increased. The ECM sets DTC P1166 if no proportional fuel adaptation occurs for a defined time after the lambda controller has reached its minimum or maximum threshold.

1. Check if fuel line pressure decreases when accelerating quickly
1) If it does, check fuel pump maximum pressure. If pressure is OK, check fuel line and filter for clogging
2. If fuel pressure is lower than specification : Check for fuel line pressure while pinching fuel return hose.
1) If pressure quickly increases, check pressure regulator
2) If pressure gradually increases, check for clogging between fuel pump and pressure regulator. If hose is not clogged, check fuel pump maximum pressure.
3. If fuel pressure is higher than specification : Is fuel line clogged?
1) If it is not, replace pressure regulator.
2) If it is, replace it
Fuel Injector Inspection
1. Check the fuel injectors for clogging or any restrictions
A. Test Condition : Ignition «OFF» & Engine «OFF»
B. Specification : No clogging and restriction
2. Is the fuel injector OK?
YES
1) Visually/physically inspect the engine mechanical problem. Repair as necessary and go to «Verification of Vehicle Repair» procedure
NO
1) Thoroughly check connectors for loose or poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and go to «Verification of Vehicle Repair» procedure
Verification of Vehicle Repair
After a repair, it will be necessary to verify that the fault has been properly repaired.
1. Install the scan tool and access the «Diagnostic Trouble Codes» screen
2. Press F4(DTAL) to select DTC information from the DTCs menu
3. Confirm that «DTC Readiness Flag» indicates «Complete». If not, drive the vehicle within conditions noted in the freeze frame data or enable conditions
4. Read «DTC Status» parameter
5. Is parameter displayed «History(Not Present) fault»?
— History (Not Present) fault : DTC occurred but has been cleared.
— Present fault : DTC is occurring at present time.
YES
1) System OK
NO
1) Go to the applicable troubleshooting procedure.
