What would happen if an analog temperature sensor were switched with a digital sensor?
If a temperature sensor meant for Analog computer use were switched with a Digital type, or vice versa, the results would be the same: the engine would be hard to start while cold due to extreme lean fuel conditions. The ECU would call for reduced fuel instead of enrichment (choke) as would be needed for cold start. After warm-up, the system would run very rich, and performance and economy would suffer. For identification purposes the Analog sensor has two black wires, while the Digital sensor has one black and one gray wire.
