The engine control unit uses info from the oil temp sensor to operate the warm-up enrichment compensator.
The oil pressure sensor (NOT switch) is only used by the pressure gauge on the dash.
The O2 sensor is considered a wear item, if the voltage stops fluctuating, the sensor is worn out and should be replaced.
