Diagnosing O2 Sensor Heater Circuit Failures MOTOR
Web23 de oct. de 2007 · I found a Tech Article here on Audiworld that says the upper resistance limit for the heater circuits on the 4-wire oxygen sensors is 20 ohms (but no source cited). I still don't know what the lower limit is supposed to be, so if anyone knows, it would be useful info to have. Web17 de ene. de 2008 · A rich mixture consumes most or all of the oxygen so the voltage generated by the O2 sensor will be high (0.6 to 1.0 volts). A leans mixture will have more available O2 left over. In this case the sensor will produce a voltage from 0.1to 0.4v. The perfect average voltage is around 0.45 v for complete combustion. irn3000 outlook.com
