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

P0345 -
Camshaft Position Sensor A Circuit (Bank 2)

Description:
The test fails when the powertrain control module (PCM) can no longer detect the signal from the camshaft position (CMP) sensor on bank 2.
Possible Causes: See the possible causes for DTC P0340.

If Indiana salts the roads during the winter months, I'd have a real close look at the wiring harness and connectors.

Indiana definitely salts the roads during the winter months.
