Hint:
Sensor 1 refers to the sensor mounted in front of the three-way catalytic converter (twc) and located near the engine assembly.
Description
Refer to dtc p2195 (see page es-292).
Monitor description
After the engine is warmed up, the ecm performs air-fuel ratio feedback control to maintain the air-fuel ratio at the stoichiometric level. In addition, active a/f control is performed for approximately 10 seconds after the preconditions are met in order to measure the a/f sensor response rate. During active a/f control, the ecm forcibly increases and decreases the injection volume a certain amount, based on the stoichiometric air-fuel ratio learned during normal air-fuel ratio control, and measures the a/f sensor response rate. The ecm receives a signal from the a/f sensor while performing active a/f control and uses it to calculate the a/f sensor response rate deterioration level.
If the a/f sensor response rate deterioration level is less than the threshold, the ecm interprets this as a malfunction and sets the dtc.
Confirmation driving pattern
Hint:
Performing this confirmation pattern will activate the a/f sensor response monitor.
Hint:
Completion of all a/f sensor monitors is required to change the value in test result.

Wiring diagram
Inspection procedure
Hint:
Intelligent tester only: malfunctioning areas can be identified by performing the a/f control function provided in the active test. The a/f control function can help to determine whether the air-fuel ratio (a/f) sensor, heated oxygen (ho2) sensor and other potential trouble areas are malfunctioning.
The following instructions describe how to conduct the a/f control operation using the intelligent tester.
Hint:
Standard
Notice:
The a/f sensor has an output delay of a few seconds and the ho2 sensor has a maximum output delay of approximately 20 seconds.
Following the a/f control procedure enables technicians to check and graph the voltage outputs of both the a/f and ho2 sensors.
To display the graph, select the following menu items on the tester: diagnosis / enhanced obd ii / active test / a/f control / user data / afs b1 s1 and o2s b1 s2; and press the yes button and then the enter button followed by the f4 button.
Hint:
If any dtcs relating to the a/f sensor (dtcs for the a/f sensor heater or a/f sensor admittance) are output, troubleshoot those dtcs first.
Rear occupant classification sensor lh circuit malfunction
Description
The rear occupant classification sensor lh circuit consists of the occupant
classification ecu and the rear
occupant classification sensor lh.

Shift position purpose
*1: Shifting the shift lever to d allows the system to select a gear suitable
for
the driving conditions.
Setting the shift lever to d is recommended for normal driving.
*2: Selecting shift ranges using s mode restricts the upper limit of the
possible
gear ranges, controls engine bra ...
