P0265 NO.2 INJECTOR CIRCUIT HIGH INPUT, CODE NO. P0268 NO.3 INJECTOR CIRCUIT HIGH INPUT, CODE NO. P0271 NO.4 INJECTOR CIRCUIT HIGH INPUT
Code No. P0262: No. 1 Injector Circuit High Input
Code No. P0265: No. 2 Injector Circuit High Input
Code No. P0268: No. 3 Injector Circuit High Input
Code No. P0271: No. 4 Injector Circuit High Input
 
 
 
 
OPERATION
  • Power is supplied to the injector from the engine control relay.
  • The engine-ECU connector terminal INJ1, INJ2, INJ3 or INJ4 makes the power transistor in the unit be in ON position, and that makes currents go on the injector.
 
 
FUNCTION
  • The engine-ECU controls the power supply interval of the injector.
  • The fuel injection amount of the injector depends on the power supply interval.
 
 
TROUBLE JUDGEMENT
Check Conditions
  • Engine is running.
  • Battery positive voltage is more than 10 V and is less than 16.5 V.
Judgement Criterion
  • The coil current is more than 4.5 A with the injector driving.
 
 
FAIL-SAFE AND BACKUP FUNCTION
  • Prohibit driving the malfunctioning cylinder injector and injector (high pressure).
 
 
PROBABLE CAUSES
  • Failed injector
  • Short circuit to power supply in injector control line
  • Damaged injector connector
  • Failed engine-ECU
 
 
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-IIISE actuator test
  • (When code No. P0262 is set) Item 1: No. 1 injector
  • (When code No. P0265 is set) Item 1: No. 2 injector
  • (When code No. P0268 is set) Item 1: No. 3 injector
  • (When code No. P0271 is set) Item 1: No. 4 injector
OK: Idling state varies.
Is the check result normal?
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
Go to Step 2.
 
STEP 2. Check injector itself.
  • Injector check (Refer to ).
Is the check result normal?
YES (Code No. P0262) : Go to Step 3.
YES (Code No. P0265) : Go to Step 4.
YES (Code No. P0268) : Go to Step 5.
YES (Code No. P0271) : Go to Step 6.
Replace the injector.
 
STEP 3. Check of short to power supply in INJ1 line between No. 1 injector connector and engine-ECU connector.
Is the check result normal?
Go to Step 7.
Repair the connector(s) or wiring harness.
 
STEP 4. Check of short to power supply in INJ2 line between No. 2 injector connector and engine-ECU connector.
Is the check result normal?
Go to Step 7.
Repair the connector(s) or wiring harness.
 
STEP 5. Check of short to power supply in INJ3 line between No. 3 injector connector and engine-ECU connector.
Is the check result normal?
Go to Step 7.
Repair the connector(s) or wiring harness.
 
STEP 6. Check of short to power supply in INJ4 line between No. 4 injector connector and engine-ECU connector.
Is the check result normal?
Go to Step 7.
Repair the connector(s) or wiring harness.
 
STEP 7. Perform signal wave pattern measurement at engine-ECU connector (Using an oscilloscope).
  • Measure engine-ECU terminal voltage.
  • Engine: Idling
  • Transmission: Neutral <M/T>, P range <CVT>
    • Code No. P0262 is set
    • Between terminal INJ1 and body earth
    Code No. P0265 is set
    • Between terminal INJ2 and body earth
    Code No. P0268 is set
    • Between terminal INJ3 and body earth
    Code No. P0271 is set
    • Between terminal INJ4 and body earth
OK: Waveforms should be displayed on inspection procedure using an oscilloscope (Refer to ).
Is the check result normal?
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
Replace the engine-ECU.
