INSPECTION PROCEDURE
HINT:

If DTCs P0441, P0446, P0450 or P0451 is output after DTC P0440, first troubleshoot DTCs P0441,
P0446 ,P0450 or P0451. If no malfunction is detected, troubleshoot DTC P0440 next.

Read freeze frame data using TOYOTA hand±held tester or OBD II scan tool. Because freeze frame
records the engine conditions when the malfunction is detected, when troubleshooting it is useful for
determining whether the vehicle was running or stopped, the engine warmed up or not, the air±fuel
ratio lean or rich, etc. at the time of the malfunction.

When the ENGINE RUN TIME in the freeze frame data is less than 200 seconds, carefully check the
VSV for EVAP, charcoal canister and vapor pressure sensor.
1 Check voltage between terminals VC and E2 of ECM connector
(See page DI±311, step 9).
NG Check and replace ECM (See page IN±31).
OK
2 Check voltage between terminals PTNK and E2 of ECM connectors
(See page DI±311, step 10).
OK Check and replace ECM (See page IN±31).
NG
3 Check for open and short in harness and connector between vapor pressure
sensor and ECM (See page IN±31).
NG Repair or replace harness or connector.
OK
Replace vapor pressure sensor.

INSPECTION PROCEDURE
HINT:
Read freeze frame data using TOYOTA hand held tester or OBD II scan tool. Because freeze frame records
the engine conditions when the malfunction is detected, when troubleshooting it is useful for determining
whether the vehicle was running or stopped, the engine warmed up or not, the air±fuel ratio lean or rich, etc.
at the time of the malfunction.
1 Check engine idle speed.
PREPARATION:
(a) Warm up engine to normal operating temperature.
(b) Switch off all accessories.
(c) Switch off air conditioning.
(d) Shift transmission into ºNº or neutral position.
(e) Connect the OBD II scan tool or TOYOTA hand±held tester to DLC3 on the vehicle.

CIRCUIT DESCRIPTION
Refer to DTC P0125 (Insufficient Temp. for Closed Loop Fuel Control (Only for California Spec.)) on Page
DI±249.
DTC No.DTC Detecting ConditionTrouble Area
Voltage output* of A/F sensor remains at 3.8 V or more, or
2.8 V or less, during engine running after engine is warmed
up (2 trip detection logic)
*: Output value changes at inside of ECM only.

A/F sensor (bank 1, 2 sensor 1)

ECM
Open or short in A/F sensor circuit
(2 trip detection logic)
HINT:

After confirming DTC P1130 or P01150, use the OBD II scan tool or TOYOTA hand±held tester to con-
firm voltage output of A/F sensor (AFS B1 S1/O2S B1 S1) from ºCURRENT DATAº.

The A/F sensor's output voltage and the short±term fuel value can be read using the OBD II scan tool
or TOYOTA hand±held tester.

The ECM controls the voltage of AFR/AFL
and AFR/AFL terminals of ECM to the fixed voltage.
Therefore, it is impossible to confirm the A/F sensor output voltage without OBD II scan tool or TOYOTA
hand±held tester.

OBD II scan tool (excluding TOYOTA hand±held tester) displays the one fifth of the A/F sensor output
voltage which is displayed on the TOYOTA hand±held tester.

(a) Connect the TOYOTA hand±held tester to the DLC3.
(b) Switch the TOYOTA hand±held tester from normal mode to check mode (See page DI±197).
(c) Start the engine and warm it up with all accessory switches OFF.

HINT:
If a malfunction exists, the MIL will light up during step (4).
NOTICE:
If the conditions in this test are not strictly followed, detection of the malfunction will not be possible.
If you do not have a TOYOTA hand±held tester, turn the ignition switch OFF after performing steps
(3) and (4), then perform steps (3) and (4) again.
INSPECTION PROCEDURE
HINT:

If DTC P1130 is displayed, check Bank 1 Sensor 1 circuit.

If DTC P1150 is displayed, check Bank 2 Sensor 1 circuit.

2 Connect the OBDII scan tool or TOYOTA hand±held tester and read value for
voltage output of A/F sensors (bank1, 2 sensor1).
PREPARATION:
(a) Connect the OBD II scan tool or TOYOTA hand±held tester to the DLC3.
(b) Warm up the A/F sensors (bank1, 2 sensor1) with the engine at 2,500 rpm for approx. 90 sec.
CHECK:
Read voltage of A/F sensors (bank 1, 2 sensor 1) on the screen of OBD II scan tool or TOYOTA hand±held
tester when you perform all the following conditions.
HINT:
The voltage of AFR
and AFL
terminals of ECM is fixed at 3.3 V and the voltage of AFR and AFL
terminals is fixed at 3.0 V. Therefore, it is impossible to check the A/F sensors (bank1, 2 sensor1) output
voltage at the terminals (AFR
, AFL
/AFR, AFL) of ECM.

Not remains at 3.8 V (*0.76 V) or more

Not remains at 2.8 V (*0.56 V) or less
*: When you use the OBD II scan tool (excluding TOYOTA hand±held tester)
HINT:

During fuel enrichment, there is a case that the output voltage of A/F sensors (bank1, 2 sensor1) is
below 2.8 V (* 0.56 V), it is normal.

During fuel cut, there is a case that the output voltage of A/F sensors (bank1, 2 sensor1) is above 3.8
V (* 0.76 V), it is normal.

If output voltage of A/F sensors (bank1, 2 sensor1) remains at 3.30 V (* 0.660 V) even after performing
all the above conditions, A/F sensors (bank1, 2 sensor1) circuit may be open.

If output voltage of A/F sensors (bank1, 2 sensor1) remains at 3.8 V (* 0.76V) or more, or 2.8 V (*0.56
V) or less even after performing all the above conditions, A/F sensors (bank1, 2 sensor1) circuit may
be short.
*: When you use the OBD II scan tool (excluding TOYOTA hand±held tester).
