2.2L Turbo (200)
CIS Digital Control system uses continuous injection system with Lambda for electronic control of mixture adjustment, emissions and ignition timing. An indicator light on dash illuminates if detonation becomes continuous or a fault is detected in circuitry.
Electronic controls include Electronic Control Unit (ECU), intake manifold pressure sensor (built into ECU), air temperature sensor, coolant temperature sensor, crankshaft speed sensor, crankshaft reference sensor, Hall Effect switch, knock sensor, throttle valve switch, brake switch, engine overheat sensor and oxygen sensor. See Fig 1 .
The ECU uses input from these sensors to control cold start valve, oxygen sensor heater, cold engine warm-up enrichment, Lambda control (frequency) valve, transistorized ignition coil, wastegate frequency valve, charcoal canister shut-off valve, fault warning light and ignition timing control.
