DTC Description
DESCRIPTION
ECM supplies a voltage of 5 V to some of the sensors systematically divided into 3 groups, respectively. Accordingly, when a short circuit develops in a sensor power source, a malfunction may occur simultaneously in the sensors belonging to the same group as the short-circuited sensor.
Sensor power supply 1
- APP sensor 1
- Crankshaft position sensor 1
- Exhaust camshaft position sensor (bank 1)
- Throttle position sensor
- Mass air flow sensor
- Intake camshaft position sensor (bank 1)
- Engine oil pressure sensor
NOTE:
If sensor power supply 1 circuit is malfunctioning, DTC P0643 and P06B0 is displayed.
Sensor power supply 2
- APP sensor 2
- Intake camshaft position sensor (bank2)
- Refrigerant pressure sensor
- Crankshaft position sensor 2
- Exhaust camshaft position sensor (bank 2)
- Fuel rail pressure sensor
Sensor power supply 3
- EVAP control system pressure sensor
DTC DETECTION LOGIC
| DTC | CONSULT screen terms (Trouble diagnosis content) | DTC detection condition | ||
| P06E6 | 11 | Internal control module (Internal Control Module Knock/Combustion Vibration Sensor Processor 1 Performance) | Diagnosis condition | Ignition switch ON |
| Signal | - | |||
| 12 | Threshold | Malfunction in the sensor power supply voltage of ECM internal circuit | ||
| Diagnosis delay time | 5 seconds | |||
POSSIBLE CAUSE
- Harness or connectors (EVAP control system pressure sensor is shorted.)
- EVAP control system pressure sensor
FAIL-SAFE
Not applicable
DTC CONFIRMATION PROCEDURE
- PRECONDITIONING
- TESTING CONDITION: Before performing the following procedure, confirm that battery voltage is 11 V or more with ignition switch ON.
>>
GO TO 2.
- PERFORM DTC CONFIRMATION PROCEDURE
-
- Turn ignition switch ON and wait at least 10 second.
- Turn ignition switch OFF and wait at least 10 seconds.
- Repeat step 1 and 2 for 2 times.
- Turn ignition switch ON.
- Check the DTC.
Is the DTC detected?
YES>>
Proceed to DTC Diagnosis Procedure .
NO-1>>
To check malfunction symptom before repair: Refer to Intermittent Incident .
NO-2>>
Confirmation after repair: INSPECTION END
