(a) Check the DTC.
(1) Initial conditions.

Battery positive voltage 11 V or more

Throttle valve fully closed

Transmission in ºPº or ºNº position

Air conditioning switched OFF
(2) Turn ignition switch OFF.
(3) Prepare the TOYOTA hand±held tester.
(4) Connect the TOYOTA hand±held tester to the
DLC3 at the lower center of the instrument panel.
(5) Turn the ignition switch ON and push the TOYOTA
hand±held tester switch ON.
(6) Switch the TOYOTA hand±held tester normal mode
to check mode (Check that the MIL flashes.).
NOTICE:
If the TOYOTA hand±held tester switches the ECM from
normal mode to check mode or vice±versa, or if the igni-
tion switch is turned from ON to ACC or OFF during check
mode, the DTC and freezed frame data will be erased.
(7) Start the engine (The MIL goes out after the engine
start.).
(8) Simulate the conditions of the malfunction de-
scribed by the customer.
NOTICE:
Leave the ignition switch ON until you have checked the
DTC, etc.
(9) After simulating the malfunction conditions, use the
TOYOTA hand±held tester diagnosis selector to
check the DTC and freezed frame data, etc.
HINT:
Take care not to turn the ignition switch OFF. Turning the ignition
switch OFF switches the diagnosis system from check mode to
normal mode. So all DTC, etc. are erased.
(10) After checking the DTC, inspect the applicable cir-
cuit.

5. CHECK FOR INTERMITTENT PROBLEMS
TOYOTA HAND±HELD TESTER only:
By putting the vehicle's ECM in check mode, 1 trip detection logic is possible instead of 2 trip detection logic
and sensitivity to detect open circuits is increased. This makes it easier to detect intermittent problems.
(1) Clear the DTC (See page DI±197).
(2) Set the check mode (See page DI±197).
(3) Perform a simulation test (See page IN±21).
(4) Check the connector and terminal (See page IN±31).
(5) Handle the connector (See page IN±31).
6. BASIC INSPECTION
When the malfunction code is not confirmed in the DTC check, troubleshooting should be performed in the
order for all possible circuits to be considered as the causes of the problems. In many cases, by carrying
out the basic engine check shown in the following flow chart, the location causing the problem can be found
quickly and efficiently. Therefore, use of this check is essential in engine troubleshooting.
1 Is battery positive voltage 11 V or more when engine is stopped ?
NO Charge or replace battery.
YES

HINT:
When the 2 or more codes for a misfiring cylinder are recorded repeatedly but no Random Misfire code is
recorded, it indicates that the misfires were detected and recorded at different times.
WIRING DIAGRAM
CONFIRMATION DRIVING PATTERN
(1) Connect the TOYOTA hand±held tester or OBD II scan tool.
(2) Record DTC and the freeze frame data.
(3) Use the TOYOTA hand±held tester to set to Check Mode. (See page DI±197)
(4) Drive the vehicle several times with the engine speed, load and its surrounding range shown with
ENGINE SPD, CALC LOAD in the freeze frame data or MISFIRE RPM, MISFIRE LOAD in the data list.
If you have no TOYOTA hand±held tester, turn the ignition switch OFF after the symptom is simulated
the first time. Then repeat the simulation process again.
HINT:
In order to memorize DTC of misfire, it is necessary to drive around MISFIRE RPM, MISFIRE LOAD in the
data list for the following period of time.
Engine SpeedTime
Idling3 minutes 30 seconds or more
1000 rpm3 minutes or more
2000 rpm1 minute 30 seconds or more
3000 rpm1 minute or more
(5) Check whether there is misfire or not by monitoring DTC and the freeze frame data. After that, record
them.
(6) Turn ignition switch OFF and wait at least 5 seconds.

(1) Connect the OBD II scan tool or TOYOTA hand±held tester to the DLC3.
(2) Start and warm up the engine with all accessories switched OFF.
(3) Run the vehicle at 70 ~ 90 km/h (43 ~ 56 mph) for 3 min. or more.
(4) Idle the engine for about 2 min.
(5) Do steps (3) and (4) again.
(6) Stop at safe place and turn the ignition switch OFF.
(7) Do step (2) to (5) again.
(8) Check the READINESS TESTS mode on the OBD II scan tool or TOYOTA hand±held tester.
If COMPL is displayed and the MIL does not light up, the system is normal.
If INCMPL is displayed and the MIL does not light up, run the vehicle steps (2) to (6) from some times and
check it.
HINT:
INCMPL is displayed when either condition (a) or (b) exists.
(a) The system check is incomplete.
(b) There is a malfunction in the system.
If there is a malfunction in the system, the MIL light up after step (7) above is done.
(2trip detection logic)
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.
TOYOTA hand±held tester
1 Connect TOYOTA hand±held tester, and read value of EGR gas temperature.
PREPARATION:
(a) Connect the TOYOTA hand±held tester to the DLC3.
(b) Warm up the engine.
CHECK:
Read EGR gas temperature on TOYOTA hand±held tester during idling.
OK:
EGR gas temperature : 55C (415F) ~ 1505C (3025F) (Not immediately after driving)
HINT:
If there is an open circuit, TOYOTA hand±held tester indicates 3.15C (37.65F).
If there is an short circuit, TOYOTA hand±held tester indicates 159.35C (318.75F).
OK Go to step 4.

(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.
(d) Drive the vehicle at 60 ~ 120 km/h (38 ~ 75 mph) and engine speed at 1,600 ~ 3,200 rpm for 3 ~ 5 min.
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.

Read frame freeze 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 Are there any other codes (besides DTC P1130, P1150) being output?
YES Go to relevant DTC chart.

2. INSPECT DIAGNOSIS (NORMAL MODE)
(a) Check the MIL.
(1) The MIL comes on when the ignition switch is turned
ON and the engine is not running.
HINT:
If the MIL does not light up, troubleshoot the combination meter
(See page BE±47).
(2) When the engine is started, the MIL should go off.
If the lamp remains on, the diagnosis system has
detected a malfunction or abnormality in the sys-
tem.
(b) Check the DTC.
NOTICE:
(TOYOTA hand±held tester only): When the diagnostic sys-
tem is switched from normal mode to check mode, it erases
all DTCs and freeze frame data recorded in normal mode.
So before switching modes, always check the DTCs and
freeze frame data, and note them down.
(1) Prepare an OBD II scan tool (complying with SAE
J1978) or TOYOTA hand±held tester.
(2) Connect the OBD II scan tool or TOYOTA hand±
held tester to DLC3 at the lower portion of the instru-
ment panel.
(3) Turn the ignition switch ON and turn the OBD II scan
tool or TOYOTA hand±held tester switch ON.
(4) Use the OBD II scan tool or TOYOTA hand±held
tester to check the DTCs and freeze frame data and
note them down (For operating instructions, see the
OBD II scan tool's instruction book).
(5) See page DI±401 to confirm the details of the DTCs.
NOTICE:
When simulating symptoms with an OBD II scan tool (ex-
cluding TOYOTA hand±held tester) to check the DTCs, use
normal mode. For codes on the DTCs chart subject to º2
trip detection logicº, turn the ignition switch off after the
symptoms have been simulated the 1st time. Then repeat
the simulation process again. When the program has
DTCs, the DTCs are recorded in the ECM.
