Code P0340 2007 Ford Fusion Description

The Camshaft Position (CMP) sensor detects the position of the camshaft. The CMP sensor identifies when piston number 1 is on its compression stroke. A signal is then sent to the Powertrain Control Module (PCM) and used for synchronizing the sequential firing of the fuel injectors. Coil on plug (COP) ignition applications use the CMP signal to select the correct ignition coil to fire. Inline engines with 2 camshafts and with Variable Camshaft Timing (VCT) are equipped with 2 CMP sensors. The second sensor identifies the position of the exhaust camshaft. The Diagnostic Trouble Code (DTC) will set when the Powertrain Control Module can no longer detect the signal from the Camshaft Position (CMP) sensor on bank 1.
