OBD2 Code P0340 in 2005 Nissan Maxima: Camshaft Position Sensor A Bank 1 Fault and Performance Issues

Model: Nissan Fault Code: P0340 Posted: 2014-04-29 23:10

Hello, I'm experiencing a persistent OBD2 fault code P0340 on my 2005 Nissan Maxima. The diagnostic trouble code indicates a 'Camshaft Position Sensor A - Bank 1 Circuit Malfunction' according to the vehicle service manual. This issue is causing significant drivability problems: the car loses power during acceleration, takes several seconds to reach 40 mph, and has difficulty starting. It feels like the engine is struggling uphill even on flat roads. I'm wondering if this could also be related to the crankshaft position sensor or a faulty ignition system. Any insights into potential causes or troubleshooting steps would be greatly appreciated.
