P0013: Camshaft B actuator control: open circuit (bank 1)
The ECU sees no current flowing through the solenoid that moves camshaft B on bank 1; usually a connector, a wire or the solenoid itself.
| Code | P0013 |

| System | Engine and transmission |
| Group | P00xx, Air, fuel and emissions |
| Type | Generic: it means the same on every make |
| Can you keep driving? | With care |
What P0013 means
Variable valve timing shifts when the valves open depending on engine speed, using oil pressure fed by an ECU-controlled solenoid. This code means the electrical circuit of that solenoid is broken, so the timing stops adjusting and the camshaft stays in its rest position. Camshaft B is usually the exhaust camshaft, although each manufacturer defines it.
Most common causes
- Solenoid connector loose, corroded or with oil inside
- Broken or chafed wire between the solenoid and the ECU
- Blown fuse or faulty power supply to the solenoid
- Burnt out or open solenoid coil
- ECU fault (uncommon)
Symptoms
- Engine warning light on
- Less power at low or high revs
- Slightly rough idle
- Slightly higher fuel consumption
Can you drive with P0013?
With care You can keep driving, as the camshaft is locked in a safe position, but the engine loses some performance and uses more fuel. Get it checked soon.

How to check it
With the engine off, unplug the solenoid connector and look for corrosion or oil on the pins. A multimeter across the solenoid should show a low resistance; if it reads nothing at all, the coil is open.
How to read and clear P0013 with Final OBD
Plug an OBD2 scanner in under the steering wheel, switch the ignition on and open Final OBD. Under Faults you’ll see P0013 with its description and whether it’s confirmed, pending or permanent.
If the engine stores it over standard OBD, with FREE you read this code with its explanation for nothing and clear it. With PRO you also read the faults of every control unit and clear them in all of them.
Clearing the code only turns the light off: if the cause is still there, it comes back. Clear it once it’s fixed, and not right before an inspection. It’s all in how to read and clear fault codes and in inspections and OBD.

How do you clear P0013?
With an OBD2 scanner and an app like Final OBD, which clears it for free if it’s stored by the engine control unit. But clearing it only turns the light off: if the cause isn’t fixed, P0013 comes back.
