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

Description:  The test fails when the powertrain control module (PCM) can no longer detect the signal from the camshaft position (CMP) sensor on bank 1.
Possible Causes: 
  • CMP circuit open
  • CMP circuit short to GND
  • CMP circuit short to voltage
  • SIG RTN open (VR sensor)
  • CMP GND open (Hall-effect sensor)
  • CMP circuit short to CMP2 circuit (if equipped)
  • CMP incorrectly installed (Hall-effect sensor)
  • Damaged CMP sensor shielding
  • Damaged CMP sensor
  • Damaged PCM
Diagnostic Aids:  Harness routing, harness alterations, incorrect shielding, or electrical interference from other systems may have an intermittent impact on the CMP signal.
