General Description
The scan tool scan tool will display camshaft position sensor data as a 0 and 1 as the sensor pulses, the scan data will switch from 0 to 1. All camshaft
position sensor data should be checked at idle. An error in the camshaft position sensor circuit should set a DTC P0340. The camshaft position sensor
