Thanks. I have jumped these terminals and no codes flashed. Any ideas?

I believe it is mounted below the air cleaner. The plug should be flat and the A,D plugs are the outside pins. Normally the connector is marked with pin locations.

Thank you. Is the ECU located under the air filter housing? There is a plug there with 4 pins. Is pins A and D on the outside of this plug?

There should be a 4 pin diagnostic plug near the ECU. With the key switch off. jumper from pin A to pin D. Turn the key switch to on. Read the codes at the dash fault light. Hope this helps.
