The P000A OBD diagnostic error code indicates that there is an issue with the car’s ‘A’ camshaft position, particularly in Bank 1, and shows that there is a slow response. This is a generic powertrain domestic trouble code for cars equipped with variable valve or cam timing.
More About Error Code P000A
The P000A code refers to the provision of slow responses from the ‘A’ camshaft position in a car. This has various implications for the drivability of a vehicle. This is because the camshaft is responsible for the intake and exhaust valves within an engine, and handles the timing of their opening and closing. The timing of this process is absolutely crucial to the proper functioning of an engine. If the PCM (powertrain control module) picks up an issue with timing, it will engage the check engine light and flag a P000A code upon diagnostic testing. The P000A code can apply to the following vehicles, as well as others:
- Subaru
- Dodge
- VW
- Audi
- Jeep
- GMC
- Chevrolet
- Saturn
- Chrysler
- Ford

What Are the Symptoms of a P000A Code?
If your car experiences issues that cause an issue with the camshaft that leads to the raising of a P000A code, you will notice a range of symptoms. Of course, the first and most generic will be the activation of the check engine light, but more specific symptoms include:
- Rough idling
- Unexpected stalling
- Increased emissions and failing of emissions tests
- Increased engine noise
As time goes by you may also find that your vehicle fails to start or that the engine dies suddenly. These are serious symptoms that indicate the need for immediate intervention as they pose safety risks to yourself and other road users.
What Are Some Causes of a P000A Code?
A car can experience a P000A code as a result of camshaft slow response issues for a number of reasons. The potential causes of these issues include, but are not limited to:
- Improper oil supply
- Contaminated oil
- Faulty position sensor
- Failed or faulty VVT actuator
- Damage to the timing chain
- Wiring issues
- PCM faults or damage
There could also be issues with the circuits that report faults, but this is less common than the issues listed above.
How Serious Is the P000A Code?
A P000A code can be very serious for your car in the long term, but you will probably find that you can drive your car without incident for a few weeks before it begins to display the previously mentioned symptoms. If you leave the issue unattended, the situation will escalate and cause drivability issues as well as potentially lead to a breakdown.
Can I Still Drive with a P000A Code?
You can drive if your car flags up a P000A code, but it is recommended that you limit how far you drive and how often you drive to avoid the issue escalating before you can visit a repair center. After some time, this issue will lead to engine failure, and this can be dangerous, especially if it happens while driving.
How Easy Is It to Diagnose a P000A Code?
Because a variety of issues can contribute to the activation of a P000A diagnostic code and proper diagnosis requires specialist tools, it can be tricky to identify the underlying causes. This is one of the reasons that it is difficult to diagnose a P000A code without professional help. In some cases, even a professional may overlook uncommon causes. For example, degraded oil pump passages and low oil pressure may be overlooked when a car’s camshaft is giving slow responses.
How Difficult Is It to Inspect a P000A Code?
Inspecting and assessing the causes of a P000A code is not difficult for a professional with specialist tools. By using a process of elimination that tests the camshaft sensor, circuit, oil control and solenoid circuit, and the timing chain, a professional should be able to quickly identify the damage and suggest effective repairs. In some rare cases, an uncommon form of damage may be at work. Most professionals will begin by looking for the most obvious causes and work from there.
Need Additional Help with Your P000A Code?
Problems with your vehicle’s camshaft will impact your vehicle’s drivability and lead to several secondary issues. If you want to deal with this properly, thoroughly, and fully, it is best to assess and act upon any damage quickly.
If you want to ensure that there are no issues in your car’s valve timing system or any other core system, the best thing you can do is take your vehicle to a local auto repair shop for a comprehensive assessment and repair.
