5. INSPECT ENGINE COOLANT TEMPERA TURE
SENSOR
(a) Resistance inspection.
(1) Using an ohmmeter, measure the resistance be-tween each terminal.
Resistance:
Approx. 20
C (68
F) 2.32 to 2.59k
Approx. 80
C (176
F) 0.310 to 0.326k 
NOTICE:
In case of checking the water temperature sensor in the wa-
ter, be careful not to allow water to go into the terminals,
and after checking, wipe out the sensor.
6. INSPECT KNOCK SENSOR
(a) Using an ohmmeter, measure the resistance between ter- minals.
Resistance: 120 to 280 k at 20
C (68
F)
HINT:
If the resistance is not specified, replace the sensor.
7. INSPECT EFI RELAY
(a) Inspect the relay continuity.
(1) Using an ohmmeter, check that there is continuitybetween terminals 1 and 2.
Specified condition: Continuity
(2) Check that there is no continuity between terminals 3 and 5.
Specified condition: No continuity
(b) Inspect the relay operation. (1) Apply battery voltage across terminals 1 and 2.
(2) Using an ohmmeter, check that there is continuitybetween terminals 3 and 5.
Specified condition: Continuity

INSPECTION
1. INSPECT MASS AIR FLOW METER
(a) Output voltage inspection.
(1) Apply battery voltage across terminals 1 (+B) and 2(E2G).
(2) Using a voltmeter, connect the positive (+) tester probe to terminal 3 (VG), and negative (±) tester
probe to terminal 2 (E2G).
(3) Blow air into the MAF meter, and check that the volt- age fluctuates.
(b) Resistance inspection. (1) Using an ohmmeter, measure the resistance be-
tween terminals 4 (THA) and 5 (E2).
Resistance:

2. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE
ASSY
(a) Resistance inspection. (1) Using an ohmmeter, measure the resistance be-
tween the terminals.
Resistance: 6.9 to 7.9
at 20
C (68
F)
(b) Movement inspection. (1) Connect the positive (+) lead from the battery to ter-minal 1 and negative (±) lead to terminal 2, and
check the movement of the valve.
NOTICE:
Confirm the valve does not adhere.
HINT:
Bad returning of the valve by entrance of foreign objects causes
subtle pressure leak to the advanced direction. Then, DTC can
be detected.
3. INSPECT THROTTLE BODY ASSY
