P0348Camshaft Position Sensor A Circuit High Bank 2
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- P0348 is the bank 2 counterpart of P0343: the signal of the intake camshaft sensor on the side without cylinder 1 stays at supply level without edges. Causes are a signal wire shorted to positive, an open signal wire held high by the module's pull-up, a broken sensor ground or a faulty sensor. A code-specific manufacturer description exists only from GM: on the Saab 9-4X V6 (GM LAU) the signal must stay high without pulses for more than 1 s, or 10 s cumulatively, and the code follows after two trips. Ford's 2023 diesel shows the same check on bank 1 (P0343: system voltage over 10 or more crank revolutions). Other GM engines and Ford petrol engines report such faults under P0345. Result: cam timing on bank 2 switched off, loss of power.
