13. TROUBLESHOOTING
13-12
Errors coding: P0507
Rotate speed of idle speed control valve faster than target idle speed
Introduction of theory and fault reason: Engine rotate speed of idle speed works by closed-loop control.
And it indicates fault if ECU performs idle speed controlling after a certain time, but the actual engine
speed faster than target idle speed.
Maintenance Tips
：
The possible faults may exists as follow:
1
） Check adjust bolt of throttle valve 、 throttle
cable 、 throttle operating condition etc. whether are
in condition or not.
2
） Too dirty inside of throttle valve body
3 ） Check crankcase enforced-air flue whether
breaks off or leaks
Errors coding: P0560 Voltage signal of system battery illogicality
Errors coding: P0562 Voltage signal of system battery is too low
Errors coding: P0563 Voltage signal of system battery is too high
Maintenance Tips
：
The possible faults may exists as follow:
1
）
Magneto damaged and disable to starting or
battery electric leakage
2
）
Magneto stator coil open circuit
3
）
Regulator of Magneto damaged
Maintenance Tips
：
Check the item as follow:
1) Check the capability of generate electricity of
Magneto(measure voltage of Magneto after
starting)
Errors coding: P0627 Control circuit of oil pump relay open circuit
Errors coding: P0628 Control circuit of oil pump relay short to ground
Errors coding: P0629 Control circuit of oil pump relay short circuit
Maintenance Tips ：
The possible faults may exists as follow:
1
） Open circuit/short to ground/short circuit
between control circuit of oil pump relay
connected to ECU and oil pump.
2
） Open circuit between relay and main relay
3 ） Magnet coil of relay open circuit
Maintenance Tips ：
Check the items as follow:
1
） Measure resistance or voltage of oil pump relay
control circuit connected to ECU.
2
） resistance between relay and main relay
3 ） resistance between the toes of relay
Errors coding: P0650 MIL lamp-driver circuit fault
Maintenance Tips
：
The possible faults may exists as follow:
1
）
Open circuit/short to ground/short circuit on
circuit of MIL lamp-driver connected to ECU.
2
）
Open circuit between MIL and main relay.
3
）
MIL lamp burnout
Maintenance Tips
：
Check the item as follow:
1
）
Measure resistance or voltage of MIL
lamp-driver control circuit connected to ECU.
