I am about to send mine in as it is off 1 full point. I have tried two vehicals " one had brand new NB's" , two 02 sensors, and still the same results. I am posting here as about 2 weeks back it " the cable from the unit to the sensor was shut in a car door cutting 2 or 3 wires and throwing a error code. I repaired the cable and I am now wondering if something could have crossed and shorted something in the unit.
I would like to know if anyone on here could run a continunity test on the cable between the connecor at the LM-1 and where you plug in the sensor. I am able to see continuity but I am also getting resistance from some of the other wires. I would really appreciate any input. Thanks as always to those who contribute
