On the 2007 Toyota Tundra with the 5.7L engine, the P1343 is pointing to a problem with the Camshaft Position Sensor. The camshaft position sensor gathers information about the vehicle’s camshaft speed and sends it to the vehicle’s engine control module (ECM). The ECM uses this data to determine the timing of the ignition, as well as the timing of the fuel injection. The sensor also plays a role in spark delivery. This sensor is located on the top, driver’s side of the engine, just to the side of the engine oil fill. Carefully inspect the electrical connector and wire harness for any loose, broken or damaged wires. If no problems are found, replace the sensor. To replace, unplug the electrical connector. Remove the sensor mounting bolt. Using a twist-and-pull method, remove the sensor from the engine. Remember to coat the o-ring on the new sensor with small amount of clean engine oil for easier installation.
