On-vehicle inspection
1. Phase sensor
(a) Turn on ignition switch but do not start engine, and place digital universal meter at DC voltage gear,
then connect 2 terminals respectively to 1 # pin and 3 # pin of sensor, and ensure the voltage is 12V.
(b) Start engine, and phase signal is read by 2
#
pin via vehicle oscilloscope.
2. Speed Sensor
(a) Remove speed sensor joint.
(b) Place digital universal meter at ohm gear, and connect 2 terminals respectively to 2 # pin and 3 # pin of
sensor, and the resistance at should be 860 1 /
2
±80 1 /
2
.
(c) Connect speed sensor joint.
(d) Place digital universal meter at AC voltage gear, and connect 2 terminals respectively to 2
#
pin and 3
#
pin of sensor, and start engine, there should be voltage output at the moment.(It is recommended to
check with vehicle oscilloscope)

Inspection
1. Spark plug
(a) Clean spark plug.
Air pressure: below 588kPa.
Time: 20 s or less
(b) Check the damage condition of spark plug and insulator. If
there is something abnormal, please replace with new spark
plug.
Recommended spark plug specification:
Made in Xianghuoju Company: K6RTC
(c) Adjust electrode gap.
