The P002A fault code, applicable to all car manufacturers, means “B Camshaft Profile Control Circuit/Open (Bank 1)“.
Background Information: The camshaft controls the opening and closing of the valves. In a variable valve timing system, the electronic camshaft adjusting valve (or oil control valve, OCV) adjusts the camshaft angle by changing the oil pressure to the camshaft adjuster (mechanical type) according to instructions from the engine control module (ECM), ensuring that the valves open and close at optimal times. This optimizes engine efficiency and power across all engine speeds. This fault code indicates a malfunction in the B (exhaust/right/rear) camshaft profile control circuit.
Tip: To quickly find fault codes, you can use a professional car fault code reader. This will help you accurately pinpoint the problem. This data can help you understand the performance of various vehicle components and troubleshoot before the problem worsens.
