1. INSPECT MASS AIR FLOW METER
(a) Check the output voltage.
(b) Measure the resistance between terminals 4 (THA) and 5 (E2).
Standard:
If the result is not as specified, replace the MAF meter.
2. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSY
(a) Measure the resistance between the terminals.
Standard: 6.9 to 7.9 W at 20 C (68 F) If the result is not as specified, replace the OCV assy.
(b) Connect the battery's positive (+) lead to terminal 1 and negative (-) lead to terminal 2, and check the movement of the valve.
NOTICE: Confirm that the valve moves freely and does not become stuck in any position.
If necessary, replace the OCV assy.
HINT: If the valve cannot return properly because of foreign matter, a small pressure leak in the advanced direction may occur and a DTC will be output.
3. INSPECT ACCELERATOR PEDAL ROD ASSY
(a) Check the accelerator pedal position sensor (see page 05-102 ).
4. INSPECT THROTTLE BODY ASSY
(a) Check the throttle position sensor (see page 05-469 ).
(b) Check the throttle control motor.
Resistance: 0.3 to 100 W at 20 C (68 F)
If the result is not as specified, replace the throttle body assy.
5. INSPECT ENGINE COOLANT TEMPERATURE SENSOR
(a) Measure the resistance between terminals 1 and 2.
Standard:
If the result is not as specified, replace the sensor.
NOTICE: If checking the ECT sensor in the water, keep the terminals dry. After the check, wipe the sensor dry.
6. INSPECT KNOCK SENSOR
(a) Measure the resistance between the terminals.
Standard: 120 to 280 kW at 20 C (68 F)
If the result is not as specified, replace the sensor
7. INSPECT RELAY (Marking: EFI, A/F)
(a) Remove the EFI relay from the engine room J/B.
(b) Remove the A/F relay from the engine room R/B No. 2.
(c) Measure the resistance of the relay.
Standard:
If the result is not as specified, replace the relay.
8. INSPECT CIRCUIT OPENING RELAY
(a) Remove the circuit opening relay from the R/B sub-assy (b) Measure the resistance of the relay.
Standard:
If the result is not as specified, replace the relay.
Approach warning
When your vehicle is too close to a vehicle ahead, and sufficient automatic
deceleration via the cruise control is not possible, the display
will flash and the buzzer will sound to alert the driver. An example of
this would be if another driver cuts in front of you while you are following
a vehi ...
