1. Check the position sensor
(a). Disconnect the socket connector of the
position sensor.
(b). In the Power "ON" Condition, check the
voltage between No.1 pin of the position
sensor and grounding with the digital
multimeter.
Voltage: 5V
Check the resistance between No.3 pin of
the position sensor and grounding with the
digital multimeter.
Resistance: 0Ω
fuwx11011 NOTICE:
While checking, check the voltage or resistance of
the camshaft position sensor in the harness side
of the engine with digital multimeter.
(c). Connect the socket connector of the position sensor.
(d). Start the engine and check the voltage waveform of No.2 pin with the automobile
oscilloscope. The voltage waveform should change consistently and regularly.
