Follow all of the steps in this procedure to obtain a usable oil pressure reading.
Be sure that the engine is filled to the correct level with SAE 10W-30 oil. The engine oil pressure graph will not be accurate if incorrect viscosity oil is used.
Remove the oil pressure switch. Connect the 1U-5470 Engine Pressure Group to the main oil manifold. Use the connection at the oil pressure switch location (1) .
Run the engine. Allow the engine oil temperature to rise to 99°C (210°F).Note: A 3°C (5°F) increase in engine oil temperature gives a 7 kPa (1 psi) decrease in engine oil pressure.Note: Make sure that the engine oil does not rise above a temperature of 115°C (239°F).
Keep the engine oil temperature consistent with the engine at the engine's rated rpm and read the pressure gauge.
Use the engine rpm and the oil pressure to locate an intersection on the engine oil pressure graph.

The results should fall within the acceptable area of the graph. If the results are not acceptable, find the cause of the problem and correct the problem. Engine failure or a reduction in engine life can be the result of continued operation with oil pressure that is outside of the acceptable range.Note: Keep a record of engine oil pressure at regular intervals. The records can indicate possible engine problems or damage. A sudden increase or a sudden decrease of 70 kPa (10 psi) in oil pressure should be inspected, even within the acceptable range of the engine oil pressure graph.
