Output at Error Cond 0 45 Volt or a 45 Volt or V High Impedance V High Impedance Factory defaults When setting the LC 1 to the slower response speed settings the measured mixture data will be averaged over the response time setting before being output You can also specify what output voltage is visible on the analog outputs during warm up of the sensor and during error conditions The High Impedance setting allows to specify that the analog outputs do not drive the output during warm up or error condition Appendix A LED blinking codes 1 Blinking steady about 2 times second Warming up 2 Blinking steady at about 4 times second Heater calibration 3 LED off No Power or free air calibration 4 Blink sequence with 2 second pause Error indication Error indication details Count the number of fast flashes between 2 second pauses The number of flashes indicates the error code as in 1 Flash Error 1 2 Flashes Error 2 And so on See Appendix B for error code details 10 Appendix B LC 1 Error Codes and Troubleshooting Tips Error Error Message Likely Root Cause Fix Code Error 1 Heater circuit shorted 1 Short in sensor 1 Replace sensor Error 2 Heater circuit open 1 Damaged sensor cable or 1 Verify Sensor connector is Cable connector not fully fully seated into unit seated Repair replace Sensor or cable Error 3 Pump cell circuit shorted 1 Short in s
5. The bung should always be welded before the Catalytic Converter Welding the bung after the catalytic converter will skew the readings toward lean The skew in readings will vary with engine load and the efficiency of the catalytic converter Leaded fuel and two stroke applications will reduce the sensor s life There are many other factors that dictate the sensor s lifespan so it is impossible to predict total sensor longevity Exhaust leaks camshaft overlap and open shorty exhausts will cause false lean readings at light engine loads Typically once the engine is under load and the exhaust gas volume increases you will see accurate readings When installed in the exhaust the oxygen sensor must be connected to a powered functional SCG 1 no error codes whenever the engine is running An un powered sensor will be damaged in a short period of time when exposed to exhaust gas Do not pre warm the sensor before starting the engine start the engine as you normal would Allowing the sensor to pre warm before starting the engine will increase the possibility of damaging the sensor from shock cooling The maximum temperature of the sensor at the bung the sensor mounting location should not exceed 500 C or 900 F If these temperatures are exceeded in your application you should install the Innovate Motorsports HBX 1 heat sink bung extender p n 3729 As the O2 sensor measures the oxygen content of the exhaust gas to provide an accu
