13. DTC: P0204, 4-cylinder Feul Injector Circuit Trouble (see Table 1-26)
Table 1-26
S/N Operation Test Results Actions
1
Connect the diagnostic instrument and adapter, and turn the
ignition switch to ON.
Next step
Yes Go to step 4
2
Disconnect the 4-cylinder fuel injector from the harness.
Check the voltage between pin 1# of the injector and the
negative pole of the power supply with a multimeter. Is the
voltage about 12V?
No Next step
Yes
Repair or replace
harness
3
Check for open circuit or short to ground between the pin 1#
of the 4-cylinder fuel injector and the main relay with a
multimeter.
No Next step
Yes Next step
4
Check for resistance between the pin 1#, and the pin 2# of
the 4-cylinder fuel injector with a multimeter. Is the resistance
between 11Ω and 16Ω under the temperatue of 20 ?℃
No Replace fuel injector
Yes Diagnosis help
5
Check the voltage between pin 2# of the injector and the
negative pole of the power supply with a multimeter. Is the
voltage about 3.7V?
No Next step
Yes
Repair or replace
harness
6
Check for short to power supply or ground between the pin
2# of the injector and the pin 47# of the ECU.
No Diagnosis help
14. DTC: P0230, Fuel Pump Control Circuit Trouble (see Table 1-27)
Table 1-27
S/N Operation Test Results Actions
1
Connect the diagnostic instrument and adapter, and turn the
ignition switch to OFF.
Next step
Yes Go to step 4
2
Disconnect the fuel pump relay, and turn the ignition switch
to ON. Measure the resistance between pin 30#, 86# of the
relay (power supply end) and the power supply negative
pole. Is the voltage about 12V?
No Next step
Yes
Repair or replace
harness
3
Check for open circuit or short to ground at the power supply
end of the relay.
No Go to step 2
Yes Replace fuel pump relay
4
Measure the voltage between the pin 85# of the relay
(control end) and the power supply negative pole with a
multimeter. Is the voltage about 3.7V?
No Next step
Yes
Repair or replace
harness
5
Check for open circuit or short to power supply or ground
between the pin 85# of the relay (control end) and the pin
69# of the ECU.
No Diagnosis help
