When is the Code Detected?

If the element is not activated or if the voltage at the Engine Control Module (ECM) terminals is a set value or less for at least a defined period when power is supplied to the A/F sensor heater (Sensor 1), a malfunction is detected and the code is stored.

Possible Symptoms

• Check Engine Light On (or Service Engine Soon Warning Light)

P1167 HONDA Meaning

The Air/Fuel Ratio (A/F) Sensor 1 is installed in the exhaust system and detects the oxygen content in the exhaust gases. The A/F sensor sends the output voltage to the Engine Control Module (ECM). A heating element for the sensor element is built into the A/F sensor (Sensor 1). It is activated and heats the sensor to stabilize and speed up the detection of oxygen content by controlling the current flowing through the heater. The current increase stabilizes when the voltage applied to the element electrode reaches a certain range because the amount of oxygen that passes through the diffusion layer is limited. The current amperage is proportional to the oxygen content in the exhaust gases, so the air/fuel ratio is detected by measuring the current amperage. The ECM compares a set target air/fuel ratio with the detected air/fuel ratio and controls the fuel injection timing.
If the A/F sensor (Sensor 1) voltage is low, the air/fuel ratio is lean and the ECM uses A/F feedback control to issue a Rich command. If the A/F sensor (Sensor 1) voltage is high, the air/fuel ratio is rich and the ECM uses A/F feedback control to issue a Lean command.

P1167 HYUNDAI Possible Causes

• Air leak or restriction in the intake or exhaust system
• Dirty engine oil or oil level too high

Possible Symptoms

• Engine light on (or engine warning light soon to be active)

P1167 HYUNDAI Meaning

The Lambda closed-loop control system is included in the engine control system. The control system regulates the upstream lambda with the HO2S signal. Rich mixtures generate high concentrations of CO, H2, and HC. Lean mixtures generate high concentrations of NOx and free oxygen.
If the lambda controller reaches the maximum or minimum threshold, feedback control is no longer possible and emissions will be increased. The ECM sets the DTC P1167 if no proportional fuel adaptation occurs for a defined time after the lambda controller reaches its minimum or maximum threshold.

P1167 INFINITI Possible Causes

• Faulty heated rear oxygen sensor, bank 2
• Open or short circuit in bank 2 heated rear oxygen sensor wiring harness
• Poor electrical connection in heated rear oxygen sensor circuit, bank 2

Technical Notes

Replacing the rear oxygen (O2) sensor usually resolves the issue

When is the Code Detected?

The P1167 code is triggered when the maximum sensor voltage is not reached at the specified voltage.

Possible Symptoms

• Check engine light on (or service engine soon warning light)
• Possible high fuel consumption
• Possible excessive smoke from exhaust

P1167 INFINITI Meaning

The heated oxygen sensor 2 (rear), located after the three-way catalyst, monitors the oxygen level in the exhaust gases on each bank. Even if the switching characteristics of heated oxygen sensor 1 (front) are shifted, the air-fuel ratio is controlled to stoichiometric by the signal from heated oxygen sensor 2. This sensor is made of zirconia ceramic. Zirconia generates a voltage from about 1 V under rich conditions to 0 V under lean conditions. Under normal conditions, heated oxygen sensor 2 is not used for engine control operation.
