The OBD/EOBD system has detected a fault in the camshaft sensor circuit "A" of bank 2. This DTC P0345 indicates problems with the camshaft sensor, its wiring or the control unit. There may be slight variations in the designation for different manufacturers, but the basic fault always relates to the camshaft sensor.

What causes can this error code have?

• Defective camshaft sensor bank 2
• Damaged or corroded wiring to the sensor
• Loose or dirty plug connections
• Defective engine control unit (ECU)
• Incorrect sensor mounting position or loose fastening
• Dirty or damaged reluctor ring on the camshaft
• Problems with the camshaft phasing (VVT system)
• Interrupted ground connection
