P0010 OBD2 Trouble Code – HELP! What the heck is wrong with my car?

P0010 OBD2 Trouble Code

 

Meaning of the P0010 OBD2 Code

The technical definition of P0010 code is ‘A’ Camshaft Position Actuator Circuit Bank 1. This diagnostic trouble code is associated to vehicles equipped with VVT or Variable Valve Timing.

Pro Tip
A P0010 OBD2 Trouble Code means you’ve got Camshaft issues. It’s also commonly caused by sludge in the engine oil, failed cam sensors, electrical faults, wiring damage, or more!

It also means the ECM is detecting an issue with the mechanical timing in the crankshaft and bank 1 camshaft.

And since the P0010 code is related to VVT-equipped vehicles, it affects a variety of major import and domestic brands like Ford, Dodge, Volkswagen, Honda, Toyota, Chevrolet, Audi, Acura, and Hyundai.

Most VVT systems are activated by the oil control valve or OCV. In some cases, the OSV is also referred to as a solenoid valve. The P0010 code is triggered if the ECM detects a low voltage circuit in the OCV.

What are the causes of a P0010 code?

 P0010 – ‘A’ Camshaft Position Actuator Circuit Bank 1  

The first letter of the fault code will indicate the family of the diagnostic trouble code. In this case, Powertrain:

  • P = Powertrain (Engine or Drive Train)

The first digit in the error code will signify if the code is generic or manufacturer specific:

  • 0 = Generic fault

The second number means specific codes for:

  • 0, 1, and 2 = Air/fuel mixture

The second number means specific codes for the Camshaft:

  • 11 = Camshaft

Since the P0010 code is closely related or accompanied by other codes like P0011, P0012, or P0021, the causes can be traced to a host of issues. This includes bad engine timing, worn-out timing components, malfunctioning crank and cam sensors, electrical faults or wiring damage, and possibly an outdated ECM.

But most of the time, a P0010 code is caused by sludge in the engine oil. Modern VVT systems utilize oil pressure to switch between cam profiles. If the oil is unable to flow due to blockage, the camshaft won’t be able to activate the desired cam profile. This is the reason why VVT-equipped vehicles need a healthy diet of frequent oil changes to avoid engine problems.

However, the P0010 code will usually be caused by a broken or faulty oil control valve. Electrical problems associated with this trouble code includes a shorted VVT circuit and/or solenoid valve.

 

What are the symptoms of the P0010 code?

The first obvious sign is an illuminated check engine light (MIL). This is followed by poor idling and reduced fuel economy. In some cases, engine problems will crop up upon reaching higher engine speeds. This means the camshaft is unable to reach the desired profile to deliver sporty performance. The funny thing is the car will run fine even with a check engine light, smooth and idling and all. But if you press the gas, you may easily feel a noticeable loss in performance.

Of course, a P0010 code also means your vehicle will fail to pass the emissions test.

How much will it cost to fix a P0010 code?

The cost will vary wildly. Electrical or wiring problems are usually related to age and should be affordable to fix ($100). But if the P0010 code is caused by damage to major engine components like stretched timing chains or bad tensioners, the cost of fixing the problem can easily reach $300 to $500 for parts and labor.

But in most cases (especially on newer vehicles), the P0010 code can easily be fixed by replacing the engine oil and filter, which is relatively more affordable than replacing timing components. In newer vehicles, an outdated ECM will only merit a visit to the dealership.
