P0349: Camshaft Position Sensor A Circuit Intermittent (Bank 2)

What does P0349 mean?

The bank 2 camshaft A input intermittently drops out or becomes erratic. The engine may run normally between episodes, so simply clearing the code does not establish that the fault has gone.

Generic OBD-II definition: Camshaft Position Sensor A Circuit Intermittent (Bank 2). Confirm applicability in your vehicle service information.

Common causes

• Loose bank 2 terminals
• Intermittent open or short in sensor wiring
• Heat-related sensor fault or damaged tone wheel

Symptoms

• Intermittent hesitation
• Stall and restart
• Check engine light

Diagnostic focus

If the failure follows engine movement under load, inspect harness tension and connector strain. Reproduce the issue safely in a workshop rather than repeatedly road-testing a stalling vehicle.

Can I keep driving with P0349?

Severity: High A position-signal fault can cause stalling or failure to restart. Avoid normal use until diagnosed; arrange towing if the engine stalls, runs severely rough, or will not start reliably.

If the check engine light is flashing or the car runs badly, stop driving and have it checked.

Typical fixes

• Record freeze-frame conditions before clearing
• Inspect bank 2 wiring for movement or heat damage
• Capture the signal during the fault and compare with crank synchronization
