P0348

Camshaft Position Sensor A Circuit High Bank 2

Q: Is it safe to drive with P0348?

Cautiously and briefly. The engine relies on cam position for timing, so it may stall or fail to restart. Fix it before relying on the vehicle.

Q: Can I just clear P0348?

It will return until the sensor or its circuit is repaired, and clearing won't prevent stalling if the signal is dropping out.

Ignition / engine timing Generic OBD-II High

What it means

P0348 means the signal voltage from camshaft position sensor A on bank 2 is reading too high. The ECM uses cam position to time fuel injection and ignition, so a bad signal can cause hard starting, stalling, or a rough-running engine. Because the fault can lead to a no-start, it's best addressed promptly.

Can I keep driving? It may run but can hard-start, stall, or drop into a limp mode — get it fixed promptly, and be prepared for a possible no-start.

How to diagnose & fix

Work through it in order

Read freeze-frame data and confirm the fault is the bank 2 camshaft sensor A circuit.
Inspect the sensor's connector and wiring for damage, corrosion, or a pushed-out pin.
Check the signal, power, and ground at the sensor against specification.
Inspect the sensor tip and reluctor wheel for debris or damage.
If wiring and reluctor are good, replace the camshaft position sensor. Clear and re-test.
