P0342 Jeep Code - Camshaft Position Sensor Circuit Low Input

Quick Answer

The Camshaft Position (CMP) Sensor circuits consist of a Powertrain Control Module (PCM) supplied 5-volt reference circuit, a low reference circuit, and an output signal circuit. Common causes include Faulty Camshaft Position (CMP) Sensor, Camshaft Position Sensor harness is open or shorted, Camshaft Position Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0342 Jeep Description

The Camshaft Position (CMP) Sensor circuits consist of a Powertrain Control Module (PCM) supplied 5-volt reference circuit, a low reference circuit, and an output signal circuit. The CMP Sensor is an internally magnetic biased digital output integrated circuit sensing device. The sensor detects magnetic flux changes between the peaks and valleys of a tone wheel attached to the camshaft. As each tooth rotates past the CMP Sensor, the resulting change in the magnetic field is used by the sensor electronics to produce a digital output pulse. The sensor returns a digital ON/OFF DC voltage pulse of varying frequency output pulses per Camshaft revolution that represents an image of the camshaft tone wheel. The frequency of the CMP Sensor output depends on the velocity of the camshaft. The PCM decodes the tooth pattern to identify the camshaft position. This information is then used to sequence the ignition timing and fuel injection events for the engine. The PCM also uses CMP Sensor output information to determine the camshaft relative position to the Crankshaft, to control the CMP Actuator operation if equipped. The Diagnostic Trouble Code (DTC) will set when the CMP Sensor signal sent to the PCM is too low.
