- INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSY Check the operation. Connect the hand-held tester to the DLC3. Turn the ignition switch to ON. Turn the hand-held tester ON. Start the engine and warm it up. Select the menu items: DIAGNOSIS / ENHANCED OBD II / ACTIVE TEST / VVT CTRL B1. Operate the OCV using the hand-held tester, then check the engine speed. Standard: SYSTEM SPECIFICATIONS Tester Operation Specified Condition OCV is OFF Normal engine speed OCV is ON Rough idling or engine stalls If the operation is not as specified, check the camshaft timing oil control valve, wire harness and check ECM.
- INSPECT THROTTLE BODY ASSY Listen to the throttle control motor operating sounds. Turn the ignition switch to ON. When pressing the accelerator pedal, listen to the running sound of the motor. Make sure no friction noises come from the motor. If friction noises exist, check the throttle body, wire harness and ECM. Check the throttle position sensor. Connect the hand-held tester to the DLC3. Turn the ignition switch to ON. Turn the hand-held tester ON. Select the menu items: DIAGNOSIS / ENHANCED OBD II / DATA LIST / ALL / THROTTLE POS. Depress the accelerator pedal. When the throttle valve is fully opened, then check that the value of the "THROTTLE POS" is within the specification. Standard: 60 % or more NOTE: When checking the standard throttle valve opening percentage, the transmission should be in the neutral position. If the result is not as specified, check the throttle body, wire harness and ECM.
- INSPECT ACCELERATOR PEDAL ROD ASSY Check the voltage. Connect the hand-held tester to the DLC3. Turn the ignition switch to ON. Turn the hand-held tester ON. Select the menu items: DIAGNOSIS / ENHANCED OBD II / DATA LIST / ALL / ACCEL POS #1, ACCEL POS #2. Operate the accelerator pedal, then check that the ACCEL POS #1 and ACCEL POS #2 values are within the specifications. Standard: ACCEL POS #1: ACCELERATOR PEDAL CONDITION SPECIFICATIONS (ACCEL POS #1) Accelerator Pedal Condition Specified Condition Released 0.5 to 1.1 V Depressed 2.5 to 4.5 V ACCEL POS #2: ACCELERATOR PEDAL CONDITION SPECIFICATIONS (ACCEL POS #2) Accelerator Pedal Condition Specified Condition Released 1.2 to 2.0 V Depressed 3.4 to 5.0 V If the result is not as specified, check the accelerator pedal rod, wire harness and ECM.

- INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSY Check the resistance. Using an ohmmeter, measure the resistance between the terminals. Standard: TESTER CONNECTION SPECIFIED CONDITION Tester Connection Specified Condition 1 (+B) - 2 (GND) 6.9 to 7.9 ohm at 20deg; C (68°F) If the result is not as specified, replace the camshaft timing oil control valve. Check the operation. Apply battery voltage across the terminals and check that the spool valve operates. NOTE: Check that the spool valve is not stuck. HINT: The spool valve may not return if foreign objects are caught in it. This may cause subtle pressure leaks to the advance side, and a DTC may be set.
- INSPECT MASS AIR FLOW METER Check the operation. Apply battery voltage across terminals 1 (+B) and 2 (E2G). Using a voltmeter, connect the positive (+) tester probe to terminal 3(VG), and negative (-) tester probe to terminal 2 (E2G). Blow air into the mass air flow meter, then check that the voltage fluctuates. If the voltage does not fluctuate, replace the mass air flow meter. Check the resistance. Using an ohmmeter, measure the resistance between the terminals. Standard: TESTER CONNECTION SPECIFIED CONDITION Tester Connection Specified Condition 4 (THA) - 5 (E2) 13.6 to 18.4 kohm 2ohmat-20°C (-4°F) 4 (THA) - 5 (E2) 2.21 to 2.69 kohm at 20°C (68°F) 4 (THA) - 5 (E2) 0.493 to 0.667 kohm at 60°C (140°F) If the result is not as specified, replace the mass air flow meter.
- INSPECT ENGINE COOLANT TEMPERATURE SENSOR Check the resistance. Using an ohmmeter, measure the resistance between the terminals. Standard: TESTER CONNECTION SPECIFIED CONDITION Tester Connection Specified Condition 1 (E2) - 2 (THW) 2.32 to 2.59 kohm at 20°C (68°F) 1 (E2) - 2 (THW) 0.310 to 0.326 kohm at 80°C (176°F) NOTE: If checking the engine coolant temperature sensor in water, be careful not to allow water to intrude into the terminals. After checking, wipe the water off the engine coolant temperature sensor. If the result is not as specified, replace the engine coolant temperature sensor.
- INSPECT THROTTLE BODY ASSY Check the resistance. Using an ohmmeter, measure the resistance between the terminals. Standard: TESTER CONNECTION SPECIFIED CONDITION Tester Connection Specified Condition 1 (M-) - 2 (M+) 0.3 to 100 ohm at 20°C (68°F) If the result is not as specified, replace the throttle body.
- INSPECT KNOCK SENSOR Check the resistance. Using an ohmmeter, measure the resistance between the terminals. Standard: TESTER CONNECTION SPECIFIED CONDITION Tester Connection Specified Condition 1 (Ground) - 2 (Output) 120 to 280 kohm at 20°C (68°F) If the result is not as specified, replace the knock sensor.
- INSPECT ACCELERATOR PEDAL ASSY Check the resistance. Using an ohmmeter, measure the resistance between the terminals. Standard: TESTER CONNECTION SPECIFIED CONDITION Tester Connection Specified Condition 3 (EP1) - 6 (VCP1) 1.5 to 6.0 kohm 1 (EP2) - 4 (VCP2) 1.5 to 6.0 kohm If the result is not as specified, replace the accelerator pedal rod.
- INSPECT MAIN RELAY Check the resistance. Using an ohmmeter, measure the resistance between the terminals. Standard: TESTER CONNECTION SPECIFIED CONDITION Tester Connection Specified Condition 3 - 5 10 kohm or higher 3 - 5 Below 1° (Apply battery voltage to terminals 1 and 2) If the result is not as specified, replace the main relay.
- INSPECT CIRCUIT OPENING RELAY Check the resistance. Using an ohmmeter, measure the resistance between the terminals. Standard: TESTER CONNECTION SPECIFIED CONDITION Tester Connection Specified Condition 1B (11) - 1A (8) 10 kohm or higher 1B (11) - 1A (8) Below 1° (Apply battery voltage to terminals 1E (5) and 1D (1)) If the result is not as specified, replace the instrument panel junction block.
