Check the 'Possible Causes' listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.
The cost to diagnose the P1554 MINI code is 1.0 hour of labor. The diagnosis time and labor rates at auto repair shops vary depending on the location, make and model of the vehicle, and even the engine type. Most auto repair shops charge between $75 and $150 per hour.
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. The diagnostic strategy for inlet and exhaust camshaft is identical.
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
