P02D1 BMW Code - Cylinder 3 Fuel Injector Offset Learning At Max Limit

Quick Answer

Zero Fuel Calibration (ZFC) is an algorithm used to detect deviations in individual injector performance from nominal. Common causes include Faulty Cylinder 3 Fuel Injector, Cylinder 3 Fuel Injector harness is open or shorted, Cylinder 3 Fuel Injector circuit poor electrical connection. 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 P02D1 BMW Description

Zero Fuel Calibration (ZFC) is an algorithm used to detect deviations in individual injector performance from nominal. In an overrun/decel fuel shut-off condition, fuel rail pressure is set to 300 bar and small injections are made from a single injector. The observed acceleration in crankshaft speed is detected and compared to the expected acceleration. If the observed acceleration deviates from the expected acceleration by more than 50%, then an additional routine is called adjusts the injection energizing time until observed acceleration matches expected. This information is then used to adjust all pilot injections on that injector to ensure correct fuel delivery. If the absolute energizing time observed for the test injection to yield the expected acceleration exceeds minimum or maximum limits, a code is set.
The Powertrain Control Module (PCM) sets the OBDII code when the observed energizing time for the test injection is 254 us or more higher than the target 430 us energizing time for the given injector.
