What are the symptoms of P0013 Code? | What are the causes of P0013?

A P0013 engine code means that your variable valve timing (VVT) solenoid or the solenoid control circuit has worn out or been damaged. You need to have your vehicle inspected by a professional right away to prevent further engine damage or a breakdown while driving. This article mainly explains the symptoms and causes of the P0013 trouble code.

P0013 Definition

Exhaust Camshaft Position – Short/open in Oil Control Valve (OCV) (Bank 1).

What Does the P0013 Code Mean?

The engine code P0013 means that there’s an issue with the solenoid that controls the oil flow to the exhaust actuator. These solenoids are vital components in variable valve timing (VVT) engines that help improve engine performance and fuel economy.
P0113 Code

Modern vehicles utilize an electronic circuit to fine-tune engine timing for maximum performance. The system uses information from the camshaft position sensor and a litany of other inputs to open and close your engine’s intake and exhaust valves through actuators to maximize fuel efficiency and power output.

When everything is running smoothly, you get far better fuel economy than you could get with a regular camshaft alone. However, if those sensors aren’t working correctly or your ECU recognizes that the camshaft position sensor is reporting an erroneous reading, your check engine light will turn on, and you’ll either get a code P0010 or P0013.

Causes of Code P0013

There are multiple causes of P0013. However, the following are the most common causes of P0013:

  • Worn Timing Components
  • Excessive engine oil sludge
  • Bad Camshaft sensors
  • Wiring issues
  • Dirty or low engine oil

1) Excessive Engine Oil Sludge

It’s by far the most common cause of a P0013. But excessive oil sludge doesn’t come from anywhere. If you’re keeping up with your scheduled oil changes, you won’t have to worry about it.

However, if it’s been 25,000 or more miles since your last oil change, a typical result is a P0013 code.

2) Worn Timing Components

The timing components in your engine wear out, and you need to replace them at regular intervals to keep everything running smoothly. Check your service manual for the recommended service intervals.

3) Camshaft Sensors Broken

The code is telling you that the actuator isn’t working due to a sensor fault. So, why not check the sensors? Sensors are notorious for failing, and it’s not unheard of for a camshaft sensor to quit later in a vehicle’s life.

4) Wiring Issue/Blown Fuse

While wiring issues aren’t that common, they aren’t unheard of either. If you’re up to date on your maintenance schedule and the camshaft sensors are working correctly, you need to make sure everything is getting power as it should.

P0013 due to Wiring Issue

Check for a blown fuse and that the sensors are getting power. If the fuse is good, but the sensor isn’t receiving power, you have a wiring issue. Unless you’re an electrical guru, you’ll likely need to replace the entire harness.

 Symptoms of Code P0013

The following are the major symptoms of P0013 trouble code:

  • Problems starting the engine
  • Poor mileage
  • Engine running rough
  • Engine performance issues
  • Engine hesitates and stalls
  • Rattling noise from the engine

How to Diagnose and Repair Code P0013

  •  Check the wiring electrical connector on the camshaft oil control valve on bank 1.
  • Scan the vehicle with an OBDII scanner and clear the code.
  • Test drive the car for 15-20 minutes after clearing the p0013 codes and see if the code will return.
  • Scan codes and record freeze frame data to determine the time of failure.
  • Confirm OCV accurate resistance between 6.9 to 7.9.
  • Examine short/open wiring connections.
  • Conduct an automaker’s recommended pinpoint analysis if code reappears, then perform the required fixes.
  • Read your car manual to get instructions on the best ways to discover and repair the p0013 error code.

How to Fix Code P0013

  1. Change the engine oil and oil filters
  2. Replace Worn Timing Components
  3. Replace the Camshaft Position Sensor
  4. Troubleshoot Electrical Fault
  5. Check the engine oil and add more oil
  6. Check the coolant level

What Repairs Can Fix the P0113 Code?

Here are the top repairs that will fix the P0113 trouble code.

  • Replace IAT sensor 1
  • Repair connection or damaged wiring
  • Replace mass air flow sensor (when integrated with the IAT)
  • Update/replace PCM

FAQ Section

How Serious is the P0013 Code?

P0013 is a moderate repair case and may not require urgent attention. However, if you choose to continue driving with a registered P0013 error code, you’ll experience the following;

Rough engine idling and hesitation. You will get high fuel mileage and carbon build-up on the valve compartment. Driving with this issue for an extended period can cause the PCM to malfunction.

Can I drive my car with a P0013 code?

Yes, but not advisable because p0013 signifies a malfunction on the engine components. The engine will not work as it should and may hamper acceleration.

Can low oil cause P0013?

Yes, a low oil level can cause P0013. Examine the oil gauge first via the oil dipstick when you notice error code P0013 symptoms.

The VVT systems needed adequate oil flow at its appropriate pressure for optimum system functioning. If you discover a low oil level, top it and wipe the code before driving the car. The origin of the issue is resolved if the code fails to return.

What are the causes of P0013?

  1. Worn Timing Components
  2. Faulty PCM
  3. Excessive engine oil sludge
  4. Bad Camshaft sensors
  5. Wiring issues
  6. Dirty or low engine oil
  7. Shortened or opened actuator solenoid
  8. Low oil pressure
  9. Faulty actuator solenoid
  10. A lousy or clogged Phaser or oil control valve
  11. Poor electrical connectivity on the actuator solenoid.

Is P0013 intake or exhaust?

Diagnostic trouble code (DTC) P0013 stands for “Exhaust “B” Camshaft Position Actuator Circuit/Open (Bank 1). It’s a generic OBD-II code that relates to the variable valve timing (VVT)—also known as variable camshaft timing—components.

What does the exhaust camshaft position actuator solenoid do?

A camshaft actuator solenoid is normally installed in the front of each cylinder head. It is used to precisely control the flow of oil into the camshaft actuator. This changes the rotation of the camshaft to adjust valve timing and valve overlap on the go.

What does the engine variable timing solenoid do?

The variable valve timing solenoid is a component of the variable valve timing system that manages the oil flow depending on the engine speed and load. A VVT solenoid in good working condition improves performance and fuel efficiency.

What repairs can fix the code?

  1. Reset the fault codes and perform a road test.
  2. Replace the oil and filter using the proper oil viscosity for the engine.
  3. Repair or replace the wiring to the camshaft oil control valve for the bank 1 exhaust camshaft.
  4. Replace the camshaft oil control valve for the bank 1 exhaust camshaft.

How do you reset a camshaft position sensor?

Unfortunately, there’s no way to reset a camshaft position sensor. If you’re having camshaft issues (check engine light on, acceleration trouble, sputtering and stalling, etc.), you’ll have to replace the part entirely.

How much does it cost to fix code P0013?

Error code P0013 repair cost varies from one car brand to another, and the actual cause of the problem.

For example, fixing your camshaft sensors often goes for $25 to $50 and more. Investigate well before buying anything to avoid overspending.
