Code P0343 2015 Toyota RAV4 Description

The Camshaft Position Sensor for the intake camshaft consists of a magnet and MRE (Magneto Resistance Element). The camshaft has a timing rotor for the camshaft position sensor. When the camshaft rotates, changes occur in the air gaps between the timing rotor and MRE, which affects the magnetic field. As a result, the resistance of the MRE material fluctuates. The camshaft position sensor converts the camshaft rotation data to pulse signals, uses the pulse signals to determine the camshaft angle, and sends it to the Engine Control Module (ECM). Then the ECM uses this data to control fuel injection and injection timing.
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).
