Description
The Engine Control Module (ECM) on the Corsa B integrates data from the full sensor network — including the crankshaft sensor, MAP sensor, coolant probe, and exhaust lambda sensor — to maintain precise combustion control and ensure the engine meets its performance and emissions targets at all times. ¶ Functions managed by this ECM include fuel injector timing and pulse width, ignition advance mapping, idle speed stabilisation, closed-loop oxygen sensor feedback, cold-start enrichment, and canister purge valve timing. It monitors and stores emissions-related fault codes compliant with EOBD protocols. ¶ Signs that the Corsa B’s ECM is failing include the engine refusing to start, stalling when warm or under load, hunting idle, black or sooty exhaust, poor throttle response, or a check engine light with codes pointing to multiple sensors simultaneously — a pattern that rarely has a sensor-level cause. ¶ This is a genuine OEM unit with part number 16204739 HK, sourced from a written-off vehicle and tested for correct operation before dispatch. Professional installation and possible coding or immobiliser adaptation are recommended.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
