WIRING DIAGRAM
INSPECTION PROCEDURE
HINT:
Read freeze frame data using the intelligent tester. Freeze frame data records the engine condition when
malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was
moving or stationary, 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.
(a) Connect the intelligent tester to the DLC3.
(b) Start the engine.
(c) Turn the tester ON.
(d) Select the following menu items: DIAGNOSIS /
ENHANCED OBD II / DATA LIST / PRIMARY / MAF.
(e) Read the values displayed on the tester.
Result
HINT:
*1: The value must change when the throttle valve is
open or closed with the engine running.

CONFIRMATION DRIVING PATTERN
HINT:
Performing this confirmation pattern will activate the mass air flow performance monitor.
1. Connect the intelligent tester to the DLC3.
2. Turn the ignition switch ON.
3. Turn the tester ON.
4. Clear DTCs (see page ES-35).
5. Start the engine, and warm it up until the engine coolant temperature reaches 70
C (158F) or higher.
6. Drive the vehicle at approximately 100 km/h (62 mph) for 20 seconds or more.
7. On the tester, select the following menu items: DIAGNOSIS / ENHANCED OBD II / DTC INFO /
PENDING CODES and check if any DTCs (any pending DTCs) are set.
Engine coolant temperature 70C (158F) or more
IAT sensor circuit OK
ECT sensor circuit OK
CKP sensor circuit OK
TP sensor circuit OK
Canister pressure sensor circuit OK
EVAP leak detection pump OK
EVAP vent valve OK
Both of following conditions 1 and 2 met -
1. Averaged engine load value ratio Less than 0.85, or more than 1.15 (varies with estimated engine load)
2. Averaged air-fuel ratio Less than -20 %, or more than 20 %
