P0346: Camshaft Position Sensor A Circuit Range/Performance — Bank 2
Do not keep driving
Expect rough running and poor starting. Ask for mechanical timing on that bank to be verified before the sensor is replaced.
What this code means
The bank 2 camshaft signal is present but implausible relative to the crankshaft. The same caution as P0341 applies with force: verify mechanical timing on that bank before replacing the sensor, since a stretched chain or a failed phaser sets this code with healthy electronics.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
