•
Set the hand tester to the × 10 Ω range and connect it to
the yellow and black leads in the connector.
Special Tool - Hand Tester: 57001–1394
If there is more resistance than the specified value, the
sensor coil has an open lead and must be replaced. Much
less than this resistance means the sensor coil is shorted,
and m ust be replaced.
Camshaft Position Sensor Resistance: 400 ∼ 460 Ω
•
Using the highest resistance range of the tester, mea-
sure the resistance between the camshaft position sensor
leads and chassis ground.
Any tester reading less than infinity (∞) indicates a short,
necessitating replacement of the camshaft position sen-
sor.

•
Turn the ignition switch and engine stop switch on.
•
Pushing the starter button, turn the engine 4 ∼ 5sec-
onds w ith the transmission gear in neutral to measure the
camshaft position sensor peak voltage.
•
Repeat the measurement 5 or more times.
Camshaft Position Sensor Peak Voltage
Standard:
0.2 V or more
If the peak voltage is lower than the standard, inspect the
camshaft position sensor.
