P34B0 A Camshaft Position Actuator Position Sensor A Circuit Bank 2
Generic electrical fault on the position sensor of the intake cam actuator on bank 2. The camshaft position sensor identifies which cylinder is on the compression stroke — without it the ECM cannot run sequential injection or coil-on-plug ignition correctly.
Is it safe to drive with P34B0?
Usually safe for short trips, but don’t ignore it: the underlying fault can get more expensive over time.
