The P001E fault code, applicable to all car manufacturers, means “A Camshaft Profile Control Circuit Low (Bank 2)“.
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) according to instructions from the engine control module (ECM), ensuring the valves open and close at optimal times. This optimizes engine efficiency and power across all engine speeds. This fault code appears if the electronic control unit (ECU) detects that the voltage of the A (intake/left/front) camshaft profile control circuit has been below the calibrated minimum for a period of time.
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.
