Our certified mechanics come to you · Get a fair and transparent estimate upfront
P002A is a diagnostic trouble code (DTC) for ""B" Camshaft Profile Control Circuit/Open". This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic. Once we are able to diagnose the problem, you will be provided with an upfront quote for the recommended fix and receive $20.00 off as a credit towards the repair. All our repairs are backed by our 12-month / 12,000-mile warranty.
Engines operate by way of a system of moving parts that open the intake valves (for allowing gas into the cylinders) and exhaust valves (which carry the vapors away). The camshaft is part of this complex timing mechanism. Some vehicles have two camshafts – a separate one for the intake and exhaust valves; “B” is the designation for the exhaust camshaft. When there’s a problem in the circuit controlling the camshaft, the timing between the crankshaft and the camshaft is affected. The PCM (powertrain control module) picks up on this discrepancy, triggering the P002A code to set.
There may be a variety of causes for this code:
This fault may cause reduced power, the engine may run rough, or the engine may crank but not start. There is typically an illuminated Check Engine light as well.
A technician typically begins by hooking the vehicle up to an OBD-II scanner in order to verify that the code is present, and check for other codes. This data along with freeze frame data is recorded, and the codes are then cleared to see if they reoccur. Next, there should be a visual inspection of the wiring and connectors to check for loose connections, corrosion, or shorts. A specialized tool may be used to test the camshaft sensor. Other tests of the crankshaft and camshaft components may help pinpoint the problem, as well as inspection of the timing chain or timing belt. If there is a physical problem with the timing belt this could cause the timing to go off far enough to trigger a code P002A.
Oftentimes the camshaft sensor is blamed, and replaced, without checking the timing chain or belt for damage or stretching. Because there can be several causes for this code, a complete inspection should be carried out in order to avoid repairs that may be unnecessary and more expensive.
This is a fairly serious code due to its potential to affect how the engine runs and even its ability to start up. In addition, if the car is experiencing reduced power due to this fault, this can create a dangerous situation on the road should you need to move quickly to avoid an accident. Even if you aren’t experiencing obvious symptoms, you should have this code investigated as soon as possible.
Repairing this code may require:
Faulty wiring or connectors are often to blame for circuitry or sensor problems. If you don’t have the proper tools to perform all of the tests necessary for a thorough diagnosis of a problem like a camshaft profile control circuit problem, don’t hesitate to consult a qualified professional. Engine timing issues can be involved and complex, and your mechanic will have all the required scanners and other tools needed to make sure the correct components are repaired.
