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 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.

Lean: During the Control the Injection Volume for A/F Sensor Active Test, the air fuel ratio sensor (sensor 1) output current (A/F (O2) Sensor Current B1S1) is consistently more than 0.037 mA, and the air fuel ratio sensor (sensor 2) output current (A/F (O2) Sensor Current B1S2) is consistently more than 0.33 mA.

Rich: During the Control the Injection Volume for A/F Sensor Active Test, the air fuel ratio sensor (sensor 1) output current (A/F (O2) Sensor Current B1S1) is consistently below -0.075 mA, and the air fuel ratio sensor (sensor 2) output current (A/F (O2) Sensor Current B1S2) is consistently below -0.86 mA.

Lean/Rich: During the Control the Injection Volume for A/F Sensor Active Test, the output current of the air fuel ratio sensor (sensor 1) or air fuel ratio sensor (sensor 2) alternate correctly.

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.


Standard:
- Control the EGR Step Position (Active Test)
0 Steps 0 to 30 Steps
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 18 to 38 kPa(abs) (2.6 to 5.5 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.
