I am testing the Lambda (O2 sensor) control unit to make sure that it works
right. The drawing from Alldata shows the WOT switch connected to the speed
relay. It also states that the speed relay closes above 3500 RPM. The
purpose is to give enrichment (more fuel) under these conditions. I jumpered
the WOT connector and nothing happened.
My question is do both WOT and above 3500 RPM need to happen to cause
enrichment or should either do it?
