soupratt Posted November 24, 2006 Share Posted November 24, 2006 Hi all, I stupidly bought the wrong sensors (ie. sensor with the wrong number of wires) as the LS400 in the US and Japan are different. I now have two 2 wire sensors and the car has single wire sensors. As both are unheated and the extra wire is earth (which 1 wire sensor does through its body) can I just use the 2 wire sensor and earth the sensor to the exhaust ? I did a bit of a search on the web without much success. Cheers Quote Link to comment Share on other sites More sharing options...
dansawyer Posted November 24, 2006 Share Posted November 24, 2006 I am not familiar with 2 wire sensors. If you have a DVM and a butane torch you can heat the sensor and measure the voltage (to ground). It will read between 0 and 1 volts when hot. 0 to .2 will be a blue flame and .7 to .9 will be a yellow flame. The lead that shows those voltages should be the same as a one wire sensor. Sensors are sensitive, they require a high impedance meter such as a newer DVM. I use a one wire sensor in an MG to 'dial in' the carbs. They will find the neutral mixure point, and will even pick up the difference between regular and E15. - Dan Quote Link to comment Share on other sites More sharing options...
