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 ma 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

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
