Code P0340 for a 2003 Jeep Liberty indicates a problem with the camshaft position sensor circuit. This can result from a faulty sensor, wiring issues, or a malfunctioning engine control module (ECM). Symptoms may include rough idling, poor acceleration, or difficulty starting the engine. It's advisable to inspect the sensor and its connections, and consider replacing it if necessary.
