DTC P0340: Camshaft Position Sensor A Circuit (Bank 1 Or Single Sensor)

P0340 - CAMSHAFT POSITION SENSOR A CIRCUIT (BANK 1 OR SINGLE SENSOR)

Description: This DTC sets when the PCM can no longer detect the signal from the camshaft position (CMP) sensor on bank 1 (vehicles with a single CMP sensor per bank) or bank 1, sensor 1 (vehicles with dual CMP sensors per bank). For additional CMP sensor location information, refer to ENGINE CONTROL COMPONENTS .
Possible Causes: CMP circuit open CMP circuit short to ground CMP circuit short to voltage SIGRTN circuit open VRSRTN circuit open CMP circuit shorted to other CMP circuits (2 or more CMP sensor systems) Damaged CMP sensor shielding CMP sensor incorrectly installed Damaged CMP sensor
Diagnostic Aids: Harness routing, harness alterations, incorrect shielding, or electrical interference from other systems may have an intermittent impact on the CMP signal.
