Hi Alain:

Thanx for your reply.It is the Wideband lambdaprobe that I am intrested in. I have worked with the Figaro's sensor and it works great. There is no need to heat the sensor. My problem is that with a lambda sensor, I am not sure how much circuitry is needed for the heating part of the sensor. Also I am not sure what make and model I can use. I have no idea what part number I am looking at. Any idea regarding the heating section would help as well.

Thank you again

Sam
