P0013: B Camshaft Position Actuator A Control Circuit/Open Bank 1
What to do
Usually still driveable with reduced performance and economy. Worth diagnosing before it develops into a phaser problem.
What this code means
The same circuit fault as P0010, but on the B actuator — normally the exhaust camshaft on bank 1. Engines with independent intake and exhaust phasing carry two solenoids per bank, and they are often the same part number, which makes swapping them between positions a quick way to prove whether the solenoid or the circuit is at fault.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
