P130A BMW Code - Camshaft Sensor Exhaust Space Loss
Quick Answer
The purpose of the diagnosis is to detect when the camshaft reference position is outside the designed range relative to the engine position from the crankshaft and to detect a signal which is not valid. Common causes include Faulty Camshaft Position (CMP) Sensor, Faulty Engine Control Module (ECM) Software, Faulty Variable Camshaft Control (VANOS) Solenoid. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P130A BMW Description
The detection of each camshaft position is done by an active hall sensor and a cam wheel, "3 asymmetric teeth". The camshaft sensor delivers 3 high and 3 low phases of different lengths per 720°CRK. The high or low pegel of the signal at the reference gap of the crankshaft signal determines the position of the engine within the combustion cycle. With that information, an engine position is calculated from the crankshaft position sensor within a range from [0 to 720]° CRK
