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

WARNING: This page does not describe the selected car, but rather 30 other vehicles, including the 2006 Mercury Mountaineer, 2006 Mercury Monterey, 2006 Mercury Montego, 2006 Mercury Mariner, and 2006 Mercury Grand Marquis.

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, improper shielding, or electrical interference from other improperly functioning systems may have an intermittent impact on the CMP signal.
