INSPECTION PROCEDURE
HINT:
Performing the ACTIVE TEST using the hand-held tester allows the relay, VSV, actuator and so on to oper-
ate without parts removal. Performing the ACTIVE TEST as the first step of troubleshooting is one method
to shorten labor time.
It is possible to display the DATA LIST during the ACTIVE TEST.
(a) Turn the ignition switch off.
(b) Connect the hand-held tester to the DLC3.
(c) Turn the ignition switch to the ON position.
(d) Push the ºONº button of the hand-held tester.
(e) Select the item ºDIAGNOSIS/ENHANCED OBD II/ACTIVE TEST/SHIFTº.
(f) According to the display on tester, perform the ºACTIVE TESTº.
HINT:
While driving, the shift position can be forcibly changed with the hand-held tester.
Comparing the shift position commanded by the ACTIVE TEST with the actual shift position enables you
to confirm the problem (see page 05-916).

INSPECTION PROCEDURE
HINT:
Read freeze frame data using the hand-held tester or the OBD II scan tool. Freeze frame data records the
engine conditions when a malfunction is detected. When troubleshooting, freeze frame data can help deter-
mine if the vehicle was running or stopped, 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.

Check for contamination between the throttle valve and the housing. If necessary, clean the throttle body.
And check that the throttle valve moves smoothly.

DTC P2196 OXYGEN (A/F) SENSOR SIGNAL STUCK
RICH (BANK 1 SENSOR 1)
HINT:
Although the title (DTC description) says ºoxygen sensorº, this DTC is related to the ºA/F sensorº.
CIRCUIT DESCRIPTION
The Air-Fuel ratio (A/F) sensor provides output voltage* approximately equal to the existing air-fuel ratio.
The A/F sensor output voltage is used to provide feedback for the ECM to control the air-fuel ratio.
With the A/F sensor output, the ECM can determine deviation from the stoichiometric air-fuel ratio and con-
trol proper injection time. If the A/F sensor is malfunctioning, the ECM is unable to accurately control air-fuel
ratio.
The A/F sensor is equipped with a heater which heats the zirconia element. The heater is also controlled
by the ECM. When the intake air volume is low (the temperature of the exhaust gas is low), current flows
to the heater which heats the sensor to facilitate detection of accurate oxygen concentration.
The A/F sensor is a planar type. Compared to a conventional type, the sensor and heater portions are nar-
rower. Because the heat of the heater is conducted through the alumina to zirconia (of the sensor portion),
sensor activation is accelerated.
To obtain a high purification rate of the CO, HC and NOx components of the exhaust gas, a three-way cata-
lytic converter is used. The converter is most efficient when the air-fuel ratio is maintained near the stoichio-
metric air-fuel ratio.
HINT:
*: The voltage value changes on the inside of the ECM only.
