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
Exhaust camshaft position sensor
Intake manifold runner control valve position sensor
EGR volume control valve
Throttle position sensor
Fuel rail pressure sensor
Mass air flow sensor

note	If sensor power supply 1 circuit is malfunctioning, DTC P06B0 is displayed.

Sensor power supply 2

APP sensor 2
Intake camshaft position sensor
Refrigerant pressure sensor
Engine oil pressure sensor
Manifold absolute pressure (MAP) sensor

Sensor power supply 3

EVAP control system pressure sensor

DTC DETECTION LOGIC

DTC CONFIRMATION PROCEDURE

1.PRECONDITIONING

TESTING CONDITION:

Before performing the following procedure, confirm that battery voltage is 11 V or more with ignitionswitch ON.

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.
