Check Engine Light Illuminated, code P0340 on Mazda B2300

The Check Engine Light may come on with a trouble code for the Cam Position Sensor (CMP), P0340. This can be caused by the negative battery cable being too close to the sensor. The cable should be repositioned, clear the trouble code, and verify that the cable is causing the problem.
