The motor in my 2008 Kia Rondo EX is cranking but won't start. I've changed the spark plugs and the cam-position sensor and checked the fuel pump. There is fuel pressure to the injectors. I don't know what to do next. The OBD2 code was P0340 cam sensor position dysfunction.
You're on the right track with looking at the camshaft-angle sensor. But rather than the actual sensor itself, the problem is likely to be within the wiring that connects the sensor to the car's computer. Without a good, solid condition, the best sensor in the world can't relay the information that the computer needs to command the engine to start.
The next step is a visit to an auto electrician who should be able to test the cam-sensor circuit and check for problems with fuses, wires, connectors and any other component that could be causing the information breakdown.
