Tech Tips

DTCs P21951D, P219523, P21961D and P219624 indicate malfunctions related to the bank 1 air fuel ratio sensor circuit.
DTCs P21971D, P219723, P21981D and P219824 indicate malfunctions related to the bank 2 air fuel ratio sensor circuit.
When any of these DTCs are stored, check the air fuel ratio sensor voltage output by entering the following menus on the GTS: Powertrain / Engine / Data List / A/F (O2) Sensor Voltage B1S1 or A/F (O2) Sensor Voltage B2S1.
Short-term fuel trim values can also be read using the GTS.
The ECM regulates the voltages at the A1A+, A2A+, A1A- and A2A- terminals of the ECM to a constant level. Therefore, the air fuel ratio sensor output voltage cannot be confirmed without using the GTS.
If an air fuel ratio sensor malfunction is detected, the ECM will store a DTC.

MONITOR DESCRIPTION

Sensor Voltage Detection Monitor:
Under air fuel ratio feedback control, If the air fuel ratio sensor output voltage is less than 2.8 V (very rich condition) for 5 seconds despite the heated oxygen sensor output voltage being less than 0.7 V, the ECM stores DTC P219624 or P219824. Alternatively, if the air fuel ratio sensor output voltage is higher than 3.8 V (very lean condition) for 5 seconds despite the heated oxygen sensor output voltage being 0.21 V or higher, DTC P219523 or P219723 is stored.

Sensor Current Detection Monitor:
A rich air fuel mixture causes a low air fuel ratio sensor current, and a lean air fuel mixture causes a high air fuel ratio sensor current. Therefore, the sensor output becomes low during acceleration, and it becomes high during deceleration with the throttle valve fully closed. The ECM monitors the air fuel ratio sensor current during fuel-cut and detects any abnormal current values.

If the air fuel ratio sensor output is 2.2 mA or higher for 3 seconds or more of cumulative time, the ECM interprets this as a malfunction in the air fuel ratio sensor and stores DTC P21951D or 21971D (stuck on high side). If the air fuel ratio sensor output is less than 0.47 mA for 3 seconds or more of cumulative time, the ECM stores DTC P21961D or P21981D (stuck on low side).

CAUTION / NOTICE / HINT

Note

Inspect the fuses for circuits related to this system before performing the following procedure.

Tech Tips

A low air fuel ratio sensor voltage could be caused by a rich air fuel mixture. Check for conditions that would cause the engine to run rich.
A high air fuel ratio sensor voltage could be caused by a lean air fuel mixture. Check for conditions that would cause the engine to run lean.
Bank 1 refers to the bank that includes the No. 1 cylinder*.

*: The No. 1 cylinder is the cylinder which is farthest from the transmission.
Bank 2 refers to the bank that does not include the No. 1 cylinder.
Sensor 1 refers to the sensor closest to the engine assembly.
Sensor 2 refers to the sensor farthest away from the engine assembly.
Read freeze frame data using the GTS. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
