Code P0343 2014 Toyota RAV4 Description
If no pulse signal is transmitted by the camshaft position sensor despite the camshaft rotating, or the rotation of the camshaft and the crankshaft is not synchronized, the ECM interprets this as a malfunction of the sensor. Also, when the sensor output voltage remains at below 0.3 V, or higher than 4.7 V for more than 4 seconds, the ECM stores a Diagnostic Trouble Code (DTC).
