CONTROL SYSTEM [FS]
CRANKSHAFT POSITION SENSOR INSPECTION [FS]
Inspection of Resistance
1. Disconnect the battery negative cable.
2. Disconnect the crankshaft position sensor
connector.
3. Measure the resistance between terminals A and
B by using an ohmmeter.
W 6 U 1 4 0 W 0 8
Inspection of Air Gap
1. Verify that the crankshaft position sensor is
installed correctly and securely.
2. Measure the air gap between the crankshaft
pulley projection and the crankshaft position
sensor by using a feeler gauge.
Specification
Approx. 550 Q
4. If not as specified, check related wiring harness. If
they are okay, replace the crankshaft position
sensor. (Refer to CRANKSHAFT POSITION
SENSOR REPLACEMENT [FS].)
Specification
0.5— 1.5 mm {0.020— 0.059 in}
3. If not as specified, replace the crankshaft pulley or
the crankshaft position sensor. (Refer to 01-40A
CRANKSHAFT POSITION SENSOR
REPLACEMENT [FS].)
CRANKSHAFT POSITION SENSOR REPLACEMENT [FS]
W 6 U 1 4 0 W 0 9
1. Disconnect the negative battery cable. Tightening torque
2. Disconnect the crankshaft position sensor 7.9— 10.7 N-m
connector. {80— 100 kgfcm , 69.5— 95.4 in lbf}
3. Remove the crankshaft position sensor.
4. Install in the reverse order of removal. 5. Inspect the air gap. (Refer to 01-40A
CRANKSHAFT POSITION SENSOR
INSPECTION [FS]), Inspection of Air Gap.)
THROTTLE POSITION SENSOR INSPECTION [FS]
Inspection of Resistance
1. Disconnect the battery negative cable.
2. Disconnect the throttle position sensor connector.
3. Using an ohmmeter, measure the resistance
between throttle position sensor terminal A and C.
W 6 U 1 4 0 W A B
W 6 U 1 4 0 W 1 0
Specification
4.0— 6.0 kQ
4. If not as specified, replace the throttle position
sensor.
5. Reconnect the throttle position sensor connector.
Inspection of Output Voltage
1. If the SST (104 Pin Breakout Box) are used,
check in the following order.
(1) Remove the PCM. (Refer to 01-40A
POWERTRAIN CONTROL MODULE (PCM)
REMOVAL/INSTALLATION [FS].)
(2) Connect the SST (104 Pin Breakout Box) to
the PCM as shown.
