P1614 MIL Request Circuit Voltage High.
from
http://www.troublecodes.net/Kia/IIRC
http://www.kiatechinfo.com/index.asp has a fairly good outline of their trouble codes under "Technical information >> DTC
The MIL(Malfunction Indicator Lamp) is on the instrument panel and has the following functions; 1) It informs the driver that a affects vehicle emission levels has occurred and that the vehicle should be taken for service as soon as possible. 2) As a bulb and system check, the MIL will come æONÆ with the key æONÆ. When the MIL remains æONÆ while the engine is running, check the powertrain system relating driveability or emissions problem.
ECM sets DTC P1614 if the ECM detects that the voltage is higher than threshold value.
Threshold value: Voltage high for 1s after ECM detects Æignition-onÆ
MIL = what we cal the "Check Engine Light" (CEL)
It is simply telling us that it has set the CEL on.

P0343 - Camshaft Position Sensor "A" Ciruit High
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 ECM and the ECM uses the CMPS signal for synchronizing the firing of sequential fuel injectors.
If there is no signal, the ECM judged as a fault and DTC is set.
No signal for crankshaft revolution of : > 200 with engine at > 600 rpm (edited).
----------------------------
All in all it looks like you probably have a cactus camshaft position sensor, or a bad electrical contact to it.
