- Generic OBD-II code · Powertrain

- Can trigger limp mode
- How the car detects it
- P0349 is the bank 2 counterpart of P0344: the signal of the intake camshaft sensor on the side without cylinder 1 is disturbed for moments – edges are missing or appear at an unexpected angle. Ford checks this on the five-tooth wheel used with variable cam timing; if edges appear where none are expected, Ford sets P0349 and switches cam timing on bank 2 off, from 200 rpm, detected within 5 s. FCA also uses the code and asks for the cam/crank synchronisation event data to be saved before the sensor is replaced, because a disturbed crank reference can look like a cam fault. GM does not use P0349. Typical causes are a loose contact at the bank 2 connector, a sensor dropping out when hot or soaked with oil moisture, and a damaged tone wheel.
