HINT:
- When any of these DTCs are stored, check the air fuel ratio sensor (sensor 1) current output by entering the following menus on the Techstream: Powertrain / Engine / Data List / A/F (O2) Sensor Current B1S1.
- Short-term fuel trim values can also be read using the Techstream.
- If an air fuel ratio sensor (sensor 1) malfunction is detected, the ECM will store a DTC.
MONITOR DESCRIPTION
Air Fuel Ratio Sensor (Sensor 1) Low/High Current:
Under air fuel ratio feedback control, If the air fuel ratio sensor (sensor 1) output current is less than -0.1883 mA (very rich condition) for 5 seconds despite the air fuel ratio sensor (sensor 2) output current being -0.0851 mA or more, the ECM stores DTC P219623. Alternatively, if the air fuel ratio sensor (sensor 1) output current is more than 0.1883 mA (very lean condition) for 5 seconds despite the air fuel ratio sensor (sensor 2) output current being less than 0.0551 mA, DTC P219524 is stored.
Air Fuel Ratio Sensor (Sensor 1) Limit Current:
The ECM monitors the air fuel ratio sensor (sensor 1) current during fuel-cut and detects any abnormal current values.
If the air fuel ratio sensor (sensor 1) output is 2.2 mA or more for more than 3 seconds of cumulative time, the ECM interprets this as a malfunction in the air fuel ratio sensor (sensor 1) and stores DTC P219519 (stuck on high side). If the air fuel ratio sensor (sensor 1) output is less than 0.47 mA for more than 3 seconds of cumulative time, the ECM stores DTC P219618 (stuck on low side).

CAUTION / NOTICE / HINT
NOTICE:
Inspect the fuses for circuits related to this system before performing the following procedure.
HINT:
- A low air fuel ratio sensor (sensor 1) current 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 (sensor 1) current could be caused by a lean air fuel mixture. Check for conditions that would cause the engine to run lean.
- 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 Techstream. 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.

PERFORM ACTIVE TEST USING TECHSTREAM (CONTROL THE EGR STEP POSITION) |
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Start the engine and warm it up until the engine coolant temperature is 75°C (167°F) or higher.
HINT:
The A/C switch and all accessories should be off.
(e) Enter the following menus: Powertrain / Engine / Active Test / Control the EGR Step Position / Data List / Engine Speed, Intake Manifold Absolute Pressure and Coolant Temperature.

(f) Check the engine idling condition and Intake Manifold Absolute Pressure values in the Data List while performing the Active Test.
NOTICE:
- Do not leave the EGR valve open for 10 seconds or more during the Active Test.
- Be sure to return the EGR valve to step 0 when the Active Test is completed.
- Do not open the EGR valve 30 steps or more during the Active Test.
OK:
The value of Intake Manifold Absolute Pressure and Engine Speed change in response to EGR step position.

Idling condition |
Steady idling |
Idling changes from steady to rough idling or engine stalls |
|
Intake Manifold Absolute Pressure (Data List) |
Intake Manifold Absolute Pressure value is 20 to 40 kPa(abs) (2.9 to 5.8 psi(abs)) (EGR valve is fully closed) |
Intake Manifold Absolute Pressure value is at least +10 kPa (1.45 psi) higher than when EGR valve is fully closed |
HINT:
During Active Test, if the idling condition does not change in response to EGR step position, then there is probably a malfunction in the EGR valve.
