Sorry. It is actually pretty simple but when you don't read these things everyday they are confusing. You want to turn the key to the on position (notice the key image on the test and it is on the number 2) and then disconnect the PCM connectors (all of them as I think there are two on this engine). You want to measure for a resistance of just the wires being shorted. If you leave the PCM connected then you will be measuring resistance of the circuit board.
Then go to the EGR valve and disconnect the connector. Put your meter on ohms make sure your leads are in the correct selection of the meter for resistance measurements.
Then just put each lead on one of the pins shown in the diagrams attached here. The K34 circuit is in the first pin and the F856 is number 2 right next to it. Just make sure the connector is held in the same position as shown with the lock portion facing up so that you are not on the wrong circuits. You can look at the back of the connector at the wire colors to ensure they are the right pins.
Let me know what other questions you have. Thanks
