Camshaft position actuator circuit open bank 1

A common mistake that occurs when taking a DIY approach to diagnosing error code P0010 is replacing the timing actuator without first attempting to clean the actuator. Another common mistake is neglecting to check the electrical circuit, which can be dangerous. Car owners experiencing any error code should always rely on the expertise of a qualified mechanic.

In addition, most manufacturers use the hydraulic pressure for the engine oil pressure in order to change the camshaft timing. Low oil levels have been known to inhibit oil from being properly channeled into the vehicle’s actuator. Any present sludge would be an indication that the oil passages leading to the actuator have been blocked.

A qualified mechanic will undergo diagnosing the root cause of this DTC by checking for any other codes that are displayed along with P0010 DTC and clearing your vehicle’s check engine light with a FIXD device. They will then inspect freeze frame data to determine what caused the code to display. They will then do a visual inspection of the bank one VVT control solenoid valve and make sure to repair any frayed or faulty wiring or connectors. After that, the mechanic will check if there is any engine sludge present. They will then undergo a resistance check of the bank one intake camshaft VVT Control solenoid and compare it to the vehicle service manual.

What does the P0010 OBD-II code mean?

The P0010 diagnostic trouble code is associated with vehicles equipped with VVT or Variable Valve Timing. Most VVT systems are triggered by the oil control valve (OCV), also called a solenoid valve. The P0010 code is generated when the ECM (engine control module) attempts to adjust the bank 1 intake camshaft timing, usually during higher speeds, by utilising one of these valves and detecting a low voltage circuit in the OCV. 

The OCV is connected directly to the ECM, which, on most vehicles, is found in the engine compartment, under the seats, under the passenger floorboard, or behind the kick panels.

It is common to see additional diagnostic trouble codes with the P0010 code, including P0011, P0012, P0020, P0021, P0022, and possibly more.

How serious is the P0010 code?

A P0010 code is moderately severe. Whilst it will not prevent your vehicle from running, you will experience a decrease in power, an increase in fuel consumption and ultimately, your car will fail a future emissions test.

What are the common symptoms of a P0010 trouble code?

Your vehicle will operate pretty normally, with the following being the most common symptoms of a P0010 code:

  • ‘Check Engine’ light illuminated
  • Poor engine idle
  • Decreased fuel economy
  • Decreased engine performance at high RPMs
  • Rattling or knocking from the engine
  • General rough running engine

What are the causes of a P0010 OBD-II code?

  • Faulty VVT control solenoid valve (common)
  • Low engine oil level
  • Oil sludge in the engine (caused by lack of oil changes)
  • Crankshaft or camshaft sensor malfunctions
  • Damaged wiring
  • Engine timing issues 
  • Worn timing components (gears, guides, chains)
  • ECM internal damage or software out of date

How to diagnose a P0010 OBD-II code?

The easiest way to diagnose an OBD-II fault code is to use an OBD-II scanner or book a diagnostic check with a trusted mechanic or garage. They will:

  • Check if there are any technical service bulletins available for your vehicle’s make and model. There may be a known issue for your car that can help resolve the problem.
  • Scan your system for other OBD-II codes.
  • Clear the fault codes and take the car for a test drive while reading the live data on an OBD-II scanner, including the freeze frame data relating to the ECM to help pinpoint the exact issue.
  • Visually inspect bank 1 variable valve timing (VVT) control solenoid valve and check for any damaged or faulty wiring and connectors.
  • Check for any engine sludge that may be present.
  • Undertake a resistance check of the bank 1 intake camshaft VVT control solenoid and compare this to the vehicle service manual to ensure the value is within specification.

How to fix a P0010 OBD-II code?

Initially, the code may be solved easily with a simple computer learned procedure or cleaning the actuator solenoid and an oil system flush. However, if this does not clear the OBD-II trouble code, then:

  • If the bank 1 VVT control solenoid valve is at fault, repair any faulty wiring or connectors.
  • If engine sludge is present, then remove and clean this.
  • If the bank 1 intake camshaft VVT control solenoid resistance is out (as per the vehicle service manual), replace the bank 1 intake VVT control solenoid.

Tips to avoid a P0010 trouble code in future?

This particular OBD-II code can be triggered through a mechanical or electrical problem, but more often than not, it’s activated through a poorly maintained engine. Whilst there isn’t a lot you can do to avoid a mechanical issue, keeping your engine clean and running smoothly will help avoid the fault. Sludge build-up is a common cause, so remembering to change your oil regularly will help prevent this problem from occurring.

What does a camshaft position actuator circuit open bank 1 mean?

What Does the P0010 Code Mean? Code P0010 stands for “A” Camshaft Position Actuator Circuit (Bank 1). The code indicates that your car's primary computer, which is also referred to as the powertrain control module (PCM), perceives a problem with one of the engine's VVT solenoids.

Where is the camshaft actuator located?

The exhaust camshaft actuator features a black electrical plug and is located closer to the rear of the vehicle on the top of the cylinder head.

Can I still drive with P0010 code?

The DTC P0010 is moderately severe, meaning it won't make your car unsafe to operate. So yes, you can drive your car. However, with time, it will lower fuel economy and reduce power. But most importantly, your vehicle will fail the emissions test.
