THROTTLE BODY
ON−VEHICLE INSPECTION
1. INSPECT THROTTLE BODY
(a) Check that the throttle linkage moves smoothly.
(b) Check the vacuum at each port.
Start the engine.
Check the vacuum with your finger.
Port nameAt idleAt 3,500 rpm
PNo vacuumVacuum
ENo vacuumVacuum
RNo vacuumVacuum
2. INSPECT THROTTLE POSITION (TP) SENSOR
(a) Disconnect the TP sensor connector.
(b) Apply vacuum to the throttle opener.
(c) Using an ohmmeter, measure the resistance between
each terminal.

(d) Reconnect the TP sensor connector.
3. INSPECT AND ADJUST DASHPOT
(a) Allow the engine to warm up to normal operating tempera-
ture.
(b) Check the idle speed.
Idle speed: 650 ± 50 rpm (N position)
(c) Open the throttle valve until the throttle lever separates from the dashpot end.
(d) Release the throttle valve gradually, and check the dash-
pot setting speed when the throttle lever touched the
dashpot end.
Dashpot setting speed: 2,200 ± 300 rpm

TEMPERATURE (ECT) SENSOR
INSPECTION
1. DRAIN ENGINE COOLANT
2. REMOVE ECT SENSOR
(a) Disconnect the ECT sensor connector.
(b) Using a 19 mm deep socket wrench, remove the ECT
sensor and gasket.
3. INSPECT ECT SENSOR
Using an ohmmeter, measure the resistance between the ter-
minals. Resistance: Refer to the chart graph
If the resistance is not as specified, replace the ECT sensor.
4. REINSTALL ECT SENSOR
(a) Using a 19 mm deep socket wrench, install the ECT sen- sor and gasket.
Torque: 24.5 N·m (250 kgf·cm, 17.5 ft·lbf)
(b) Connect the ECT sensor connector.
5. REFILL ENGINE COOLANT
