Errors coding: P0261 Control circuit of single cylinder injector short to ground
Maintenance Tips
：
The possible faults may exists as follow:
1
）
All drivers ECU pin connected short to
ground
Maintenance Tips
：
Check the item as follow:
1
）
Measure ECU pin connected resistance
to ground
Errors coding: P0262 Control circuit of single cylinder injector short circuit
Maintenance Tips ：
The possible faults may exists as follow:
1
） Short circuit between circuit ECU
connected and other electrical source
circuits
Maintenance Tips ：
Check the item as follow:
1
） Measure the voltage of circuit ECU pin
connected

Errors coding: P0322 Non-rotate speed sensor pulse signal (short circuit or open
circuit)
Explanation: After starting engine, ECU will measure signal of trigger and other signals
together, judging the losing of trigger signal by signal rationality system.
Maintenance Tips
：
The possible faults may exists as follow:
1
） Trigger rotate speed sensor ECU cable
connected open circuit
2
） Trigger circuit ECU connected short
circuit.
3
） Trigger coil open circuit.
Maintenance Tips ：
1 ） Measure resistance between trigger
and ECU cable connected
2
） Measure resistance of trigger
3 ） Measure trigger peak value voltage
Errors coding: P0444 Control circuit voltage of idle air control valve open circuit
Maintenance Tips
：
The possible faults may exists as follow:
1
）
Open circuit between ECU circuit
connected and no.2 pin of idle air control
valve.
2
）
The circuit that no.1 pin of idle air control
valve connected to main relay open way.
3
）
Electromagnetism coil between no.1 pin
and no.2 pin open way.
Maintenance Tips
：
1
）
Check the connection or breaking of
cable related connection.
2
）
Measure resistance of idle speed valve.
