P001A Code- 'A' Camshaft Profile Control Circuit/Open Bank 1

What Does Code P001A Mean

P001A is the OBD-II generic code that appears when the PCM detects a noticeable lack of synchronization between the movement of the camshaft and the crankshaft. Because the engine needs gas inside the cylinder, which is what A camshaft valves manage, any issues with the valves are a serious problem. The engine uses intake valves to bring fuel into its cylinders. There are also exhaust valves, but all of the valves are run on the camshaft and if there is a code that indicates that the circuitry responsible for operating the camshaft, it will mean that a host of performance issues can occur.

How does a mechanic diagnose the P001A code?

The P001A code is diagnosed by the technician using the OBD-II scanner. They ensure the code is present and look for any other codes that could be a sign of another issue. They use the freeze frame data too, and then clear the codes before retesting to see if the P001A appears.They will perform a visual inspection of any connections or wiring to ensure there are no open, shorts, corrosion or disconnections. They will make repairs as needed. They then use a scanner and digital ohm meter to test their camshaft's sensor and circuitry as well as that of the crankshaft and related components. The timing chain or belt may be tested as well.

P001A OBDII Repair :

With P001A code so start with the basics like a fuel pressure and fuel volume test. Or, you can start on the electrical side by doing a voltage drop on both the power and ground connections for the fuel pump. Some shops are reporting corrosion on the fuel pump ground that reduces power and fuel pressure.

Excessive air inflow can be caused by a vacuum leak, a dirty sensor or, an exhaust gas recirculation valve not closing properly. If the problem is not enough fuel, the culprit may be dirty injectors or fuel filters, a weak fuel pump or a leaky fuel pressure regulator. The lean fuel mix error may be accompanied by rough idling, engine misfires, hesitation during acceleration and overall poor engine performance.
