1.5 Digifant I Engine Management SystemThe Digifant I engine management system for 1991 and later 8-valve models (engine code RV) sold in California is very similar in operation to Digifant II. The most significant difference in the Digifant I system is adaptive circuitry for fuel metering. The system can adjust its own operating range in response to changing conditions brought about by normal engine wear, minor vacuum leaks, change of altitude, etc. There is little or no need for periodic maintenance adjustments. Another feature of the Digifant I system is self-diagnosis of system faults. For more information on the fault diagnosis system, and on the fuel injection functions of the Digifant I system, see 7. Digifant II Fuel Injection and 8. Digifant I Fuel Injection. Additional information on the oxygen sensor system and other emission controls is covered in EXHAUST SYSTEM AND EMISSION CONTROLS. The ignition functions of the system, including the knock sensor, are covered in IGNITION. |
