Re: Heated or not O2 sensor

["lpwcruzr" <lpwcruzr@netzero.net>]

Well I might sound like an idiot but,, How do I do this? My electrical and
emissions manual has nothing in it on how to diagnose an O2 sensor. All I
can find is the wiring diagram. It shows what looks to be 45volts in the PCM
at the O2 sensor input. Do I need a scan tool at the ALDL for this, or can I
check any of this with a volt meter at the O2 sensor??
