DTC P0340 Camshaft Position Sensor "A" Circuit (Bank 1 or Single Sensor)


DESCRIPTION

The camshaft position sensor is installed on the cylinder head. The sensor plate has one tooth on its circumference, and is installed on the camshaft timing pulley. When the camshaft rotates, the tooth on the camshaft timing pulley passes through the crankshaft position sensor. The generated voltage in the sensor acts as a signal. The ECM determines each cylinder position based on the combination of this signal and crankshaft position sensor output.

DTC No.

INSPECTION PROCEDURE

УКАЗАНИЕ:
Read freeze frame data using an intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.
1.INSPECT CAMSHAFT POSITION SENSOR (POWER SOURCE VOLTAGE)

    Standard voltage:
    Tester Connection
    		Switch Condition
    		Specified Condition
    B70-3 (VG) - Body ground
    		Ignition switch ON
    		9 to 14 V

  1. Reconnect the camshaft position sensor connector.
