Posted by Thomas Meacham on April 05, 2001 at 05:21:22:

I am looking at the connector for the O2 sensor. It's a 4 wire unit so there is supposed to be 12 volts for power plus signal plus ground. With the key in the ON position, but the engine not running, I do not have the 12 volts. Is this normal? Will the 12 volts come active once the engine is started. I there a bad relay?

I will really appreciate this info.

Best Regards,

Tom
