FYI - Cam position sensor malf. (code P0343 & P0340) info
Issue was the cam position sensor voltage out of range causing check engine light to come on.

Troubleshooting: Remove boot of sensor(s) and check voltages. Sensor plug was labelled: Wire #3 is ground, #2 is sensor voltage, #1 is sensor power (about 13V when engine running). Normally #2 is around 6-7V. Mine was 12V...

Checked other sensor and it was good (#2 at 6-7V) so I replaced just the passenger side.
