Code P0013: “B” Camshaft Position Actuator Circuit (Bank 1)

In this guide, we here at AutoZone attempt to answer the question, "how do I fix trouble code P0013?" We will dive into the meaning, symptoms, causes and significance of this diagnostic trouble code, before finally shedding light on possible steps to resolve your problem.

What Does the Code P0013 Mean?

As with most diagnostic Powertrain trouble codes, P0013 is generic and is applicable across all makes and models that use an OBD-II system. Also, like most trouble codes, while the meanings might be the same, the steps to repair any damage or problems is likely unique to your vehicle. Now that the generic information is out of the way let’s explore the specifics of this error message. P0013 refers to the variable camshaft timing or variable valve timing components and the Powertrain control module or the engine control module. Also, the letter B is in reference to the rear, right or exhaust camshaft as compared to the driver’s seat. Bank one is in reference to the side of the engine containing cylinder one. The trouble code will occur when the Powertrain control module or the engine control module senses or detects a short to ground, short to voltage or an open circuit.

Are There Any Symptoms?

You might experience several symptoms with this particular error code. However, the most common issue is the engine running rough. Also, as with any diagnostic trouble code the malfunction indicator lamp or the check engine light will ignite, alerting the driver to a problem. While you might not experience any significant issues when driving with this specific problem, it is essential, as it is with any error code alert, to take the problem seriously, and attempt to resolve the issue as soon as possible. Unfortunately, one minor issue can quickly snowball into more significant and complex problems. Therefore, when the check engine light pops on, don’t waste any time diagnosing and getting to the bottom of the underlying problem.

What Are the Primary Causes?

While some trouble codes have a litany of potential causes, P0013 is not one of those codes. The problem can typically be traced back to one of three possible issues. However, it is necessary to note that the code could just as easily be a combination of these three issues. First, you could have an oil control valve or solenoid valve with an open or short in the circuit. Second, the oil control valve could be faulty. Third, the Powertrain control module or engine control module could be damaged. Again, when performing diagnostics, check all three potential issues to ensure that the problem is not a combination of several factors.

What Is the Solution?

The first step to take before diagnosing and resolving any problem with your vehicle is to ensure that the factory service manual is nearby. This manual will provide you with the steps and specifications that are specific to your vehicle’s make and model. Once you have your manual, you can use a digital volt ohm meter to measure the camshaft oil control valve resistance. If the reading is not within the range specified in the manual, then you will need to replace the valve. Next, use your tool to verify all connections and wiring between the valve and the control module. Fix any problems that arise and then retest the system to make sure your issue is resolved. The OBD-II scanner error code P0013 problem will not present with extremely noticeable symptoms, but it should not be ignored. Follow the steps provided in the solution section and always refer back to your service manual when repairing or replacing critical components.

Refer to the service manual for specific diagnostic, repair and tool information for your particular vehicle. Always chock your wheels prior to lifting a vehicle. Always disconnect the negative battery cable before servicing an electrical application on the vehicle to protect its electrical circuits in the event that a wire is accidentally pierced or grounded. Use caution when working with automotive batteries. Sulfuric acid is caustic and can burn clothing and skin or cause blindness. Always wear gloves and safety glasses and other personal protection equipment, and work in a well-ventilated area. Should electrolyte get on your body or clothing, neutralize it immediately with a solution of baking soda and water. Do not wear ties or loose clothing when working on your vehicle.
