|P0340 KIA code description

The Camshaft Position Sensor (CMPS) is a sensor that detects the compression TDC of the NO. 1 cylinder. The CMPS consists of a hall type sensor and a target on the end of the intake camshaft. When the target triggers the sensor, the sensor voltage is 5V. If not, the sensor voltage is 0V. These CMPS signal is sent to the Powertrain Control Module (PCM) and the PCM uses the CMPS signal for synchronizing the firing of sequential fuel injectors.
