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 NISSAN Meaning

The heated oxygen sensor 2 (rear), 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.

P1168 ACURA 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. An increase in current stabilizes when the voltage applied to the element electrode reaches a certain range because the amount of oxygen that is routed 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.
