Reading Fourth dimension: 4 minutes
If you're looking for ways to fix a P0013 lawmaking, read on for more information on its definition, causes, and symptoms.
What Does the P0013 Lawmaking Mean?
Diagnostic trouble code (DTC) P0013 stands for "Exhaust "B" Camshaft Position Actuator Excursion/Open (Banking company one). It's a generic OBD-II lawmaking that relates to the variable valve timing (VVT)—also known every bit variable camshaft timing—components.
In a traditional engine, valve timing is fixed. Just in an engine with VVT, the camshaft position can exist adjusted, thereby altering valve timing. The result is improved performance, increased fuel economy, or both.
The primary components inside the VVT system are the camshaft actuators (also known as phasers) and the VVT solenoids (too known as camshaft position actuator solenoid valves).
The camshaft position actuator solenoid valve controls the oil flow to the actuator, which in turn, advances or retards the camshaft.
Solenoid operation is controlled past the auto's primary computer, also known as the powertrain control module or PCM. The P0013 code gets logged if it perceives a problem with the camshaft actuator solenoid or its circuit.
To learn the possible causes of P0013, read the next section.
For a technical discussion of how the camshaft actuator works, read our explanation here.
What are the Possible Causes of the P0013 Code?
Manufacturers may have different names for the P0013 lawmaking, and the possible causes may differ depending on the make and model of your automobile.
Hither are the virtually common causes of an exhaust camshaft position actuator solenoid valve command circuit problem or code P0013:
- Bad VVT solenoid (aka oil control valve)
- Problems with the VVT solenoid control circuit (windings or wiring)
- Bug with the PCM, such as a pending software update
- Contaminated engine oil obstructing the VVT solenoid screen. NOTE: This is a mutual occurrence! Regular OEM specified oil change intervals using exactly the right kind of oil and always allowing the engine to reach operating temperature on every starting time will reduce the probability of the sludge that causes this.
What are the Mutual Symptoms of the P0013 Code?
A bad camshaft position actuator solenoid valve control circuit frequently comes with symptoms that you should never ignore or prolong.
With a P0013, hither are the signs y'all should spotter out for:
- Issues starting the engine
- Poor mileage
- Engine running rough
- Engine performance bug
- Engine hesitates and stalls
- Rattling racket from the engine
How to Diagnose the P0013 Code
To resolve the P0013 fault code, you lot'll need to make up one's mind its exact cause, which can prove challenging. If you are non confident with your DIY automotive repair skills, information technology's best to leave the task to your trusted mechanic. Otherwise, yous can runway down the lawmaking and make up one's mind what's causing it by performing your own diagnosis.

How to Fix the P0013 Code
Considering various issues tin trigger the P0013 code, information technology tin exist quite hard to resolve it. The solution varies based on its exact cause and the vehicle's make and model.
For example, the documented solutions to a P0013 code in a Chevy Equinox include replacing the exhaust camshaft actuator solenoid and intake camshaft actuator solenoid or replacing just the onetime. Nevertheless, these Chevy fixes for a P0013 aren't universal and may not work for other makes and models that experience this code.
If you lot are confident with your automotive know-how, you can address the consequence yourself past doing some research—perform an accurate diagnosis, and so do some research on potential fixes for your specific vehicle.
You can rely on online automobile repair resources and guides, such as an ALLDATA subscription, and check your possessor'south manual to place the best mode to resolve the P0013 code.
How does the Camshaft Actuator Work?
The ECM/PCM sends a "pulse width" bespeak to the solenoid. That means it turns the solenoid on and off really fast. The longer the solenoid is on during each pulse, the more oil pressure is delivered to the actuator.
The cam sensor (CMP) on the bank being controlled closes the feedback loop so the ECM/PCM tin can determine how much camshaft advance is needed (depending on engine load, speed, etc.) and how well the camshaft is really being controlled by the activity of the solenoid.
The ECM/PCM sets a target (desired) angle for the camshaft and then duty cycles the solenoid, delivering oil pressure to the camshaft actuator inside the camshaft bulldoze gear to change the relationship of the gear to the camshaft.
If that angle change doesn't happen, the ECM/PCM increases the solenoid's duty bicycle (turns it on for a larger percentage of the fourth dimension), attempting to run into that cam angle target. If the duty wheel consistently goes too high (struggling to meet the target), the ECM/PCM sets the P0013 code.
A simpler cause for this P0013 might be that the ECM/PCM detects an electrical issue with the solenoid circuit or winding; the circuit and solenoid winding are the easiest things to check first.
