(b)Check the DTC, Using the hand±held tester.
NOTICE:
Hand±held tester only:
When the diagnostic system is switched from normal mode
to check (test) 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)Use the hand±held tester to check the DTCs andinstructions, see the hand±held tester instruction
book.
(2)See page 05±996 to confirm the details of the
DTCs.
(c) Clear the DTC. (1) When using the hand±held tester:The following operation will erase the DTC and
freeze frame data. Operate the hand±held tester to
erase the codes.
(2) When not using the hand±held tester: Remove the EFI fuse from engine room J/B for 60
seconds or more.
3. INSPECT DIAGNOSIS (CHECK MODE)
HINT:
Hand±held tester only:
Compared to the normal mode, the check mode has high sens-
ing ability to detect malfunctions.
Furthermore, the same diagnostic items which are detected in
Normal mode can also be detected in Check mode.
(a) Check the DTC. (1) Check the initial conditions.

Battery voltage 11 V or more

Throttle valve fully closed

Shift lever in P or N range

Air conditioning switched OFF
(2) Turn the ignition switch OFF.
(3) Prepare the hand±held tester.
(4) Connect the hand±held tester to DLC3.
(5) Turn the ignition switch ON and switch the hand± held tester ON.
(6) Switch the hand±held tester from Normal mode to Check mode (Check that the MIL flashes).
NOTICE:
If the hand±held tester switches the ECM from the normal
mode to the check mode or vice±versa, or if the ignition
switch is turned from ON to ACC or OFF during the check
mode, the DTC and freeze frame data will be erased.
(7) Start the engine (MIL goes off after the enginestarts).

(8) Simulate the conditions of the malfunction de-
scribed by the customer.
NOTICE:
Leave the ignition switch ON until you have checked the
DTCs, etc.
(9) After simulating the malfunction conditions, use the
hand±held tester diagnosis selector to check the
DTCs and freeze frame data, etc.
HINT:
Take care not to turn the ignition switch OFF, as turning it off
switches the diagnosis system from Check mode to Normal
mode, which all DTCs etc. are erased.
(10) After checking the DTC, inspect the applicable cir-
cuit.
(b) Clear the DTC.
(1) When using the hand±held tester:
The following operation will erase the DTC and
freeze frame data. Operate the hand±held tester to
erase the codes.
(2) When not using the hand±held tester:
Remove the EFI fuse from engine room J/B for 60
seconds or more.
4. DATA LIST
HINT:
According to the DATA LIST displayed by the hand±held tester, you can read the value of the switch, sensor,
actuator and so on without parts removal. Reading the DATA LIST as the first step of troubleshooting is one
of the methods to shorten the work time.
(a) Warm up the engine.
(b) Turn the ignition switch OFF.
(c) Connect the hand±held tester to the DLC3.
(d) Turn the ignition switch ON.
(e) According to the display on tester, read the ºDATA LISTº.

CIRCUIT DESCRIPTION
Refer to DTC P0 130 on page 05 −82.
HINT:
The ECM provides a pulse width modulated control circuit to adjust current through the heater. The heated
oxygen sensor heater circuit uses a relay on the B+ side of the circuit.

INSPECTION PROCEDURE
HINT:
SIf different DTCs related to different systems that have terminal E2 as the ground terminal are output
simultaneously, terminal E2 may have an open circuit.
SRead freeze frame data using the hand−held tester . Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, freeze frame data can help determine 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.
