Ignition Timing Control System: Altima

Ignition timing is controlled by ECM according to engine operating conditions, based on inputs from various sensors, including Camshaft Position (PHASE) sensor, Mass Airflow (MAF) sensor and Engine Coolant Temperature (ECT) sensor. Optimum ignition timing for various driving conditions is preprogrammed and stored in ECM.
