Description
The Engine Control Module (ECM) governs the full suite of engine management functions on the Vectra B, continuously processing data from the crankshaft position sensor, mass airflow meter, coolant temperature sensor, and exhaust lambda probe to deliver optimal fuel injection timing, ignition advance, and idle stability. ¶ This ECM controls sequential fuel injection, closed-loop lambda correction, knock sensor-based ignition retard, idle speed through the bypass air valve, and activation of auxiliary systems including the cooling fan and evaporative emissions purge valve. ¶ ECM-related issues on the Vectra B can include intermittent or permanent engine management lights, rough idle, misfires under load, stalling in traffic, poor fuel consumption, failed emissions testing, or fault codes spanning multiple unrelated systems that cannot be traced to individual sensors. ¶ This is a genuine used OEM unit bearing part number 16202319 NL, removed from a written-off donor vehicle and fully tested before dispatch. Professional installation is recommended, and coding or immobiliser adaptation is likely required after fitting.
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.
