Success,
I tried the continuity adjustment to no avail. But when adjusting to the correct voltage test. It solved both the ode and the 16 flashes of the AT temp lamp. Sometimes it is amazing how seemingly unconnected symptoms can be corrected with one correction. Note I do not think the Ohm test is correct for the 3 wire sensor. Please use the voltage test you will find in similar posts. It is right on. BTW, number 2 connector is the middle one. A long sewing needle inserted next to the wire and into the connector while connected will allow for very easy testing and adjustment.
