P0345 means the ECM can't get a valid signal from camshaft position sensor A on bank 2 (the bank that doesn't contain cylinder 1). Fuel injection sync and variable valve timing accuracy drop until it's fixed.

P0345 is a electrical-related diagnostic trouble code classified as moderate severity. When your vehicle's ECU detects this condition, it stores P0345 and illuminates the check engine light.
If your vehicle has triggered P0345, you may notice one or more of these symptoms:
Here are the most common causes of P0345, ranked by how likely they are to be the culprit:
Generally yes, for short-term driving. You can drive short distances, but expect rough running, hard starts, and possible stalling. Without a clean CMP signal the ECM falls back to crankshaft-only timing, which is less precise and hard on the catalyst if you leave it for weeks.

Bank 2 is the side that doesn't contain cylinder 1. On most transverse Japanese V6s (VQ35, J35) it's the firewall-side bank. On Ford Modular V8s it's the driver side. On GM LS engines it's the passenger side. Check a factory bank diagram before ordering parts, this is the single most common wasted repair on P0345.
You can clear it, but if the fault is still present it'll return in a few drive cycles. The real cost of ignoring it is catalyst wear, fuel trims and injector timing get sloppy and a €600 cat converter is a lot worse than a €50 sensor.
On engines under about 120,000 km a sensor or connector fix is usually enough. On known chain-stretch platforms (VAG 2.0 TFSI EA888 Gen 2, BMW N20/N47, Nissan VQ35) verify cam-to-crank phase before assuming the sensor. Replacing a sensor on a stretched chain is throwing money away.
Two things: an overfill can push oil past the cam seal and drown the sensor connector, or the tech bumped the connector loose while working around the valve cover. Pull the connector, dry it, dielectric-grease it, and reseat it before buying anything.
Rarely on its own. Most modern engines can start on crank signal alone and then sync the cam. A hard no-start with P0345 usually means the CKP signal is also gone, or the timing chain has jumped teeth, at that point you're diagnosing mechanical damage, not a sensor.

A flashing check engine light is not the same as a steady one. It almost always means an active misfire that can wreck your catalytic converter in minutes.
