Oil Pressure and Circuit Combination Chart

Valid combinations for Circuits A, B, and C are shown in the figure. ON means that the switch is grounded with a resistance less than 50 ohms at 0 volts; OFF means that the switch is open with a resistance greater than 50k ohms at 12 volts.

Note that resistance should be measured with the engine running. When the transmission's pass through connector is disconnected from the vehicle harness while the engine is running, multiple diagnostic codes will set. Clear these codes when you are finished with this procedure.
