The NEW procedure requires the engine oil pressure to be measured at idle AND at 3000 RPM. This standard has changed to provide an easier inspection. These changes will be added soon to the applicable Service Manuals. SERVICE PROCEDURE / INFORMATION: REMINDER: Customer satisfaction and retention starts with performing quality repairs. IMPORTANT NOTES: • Always confirm the oil level is at the proper level prior to inspection. • The standard oil pressure value is based on an engine oil temperature of 80°C (176°F). • If the oil pressure is OUT of the specification, diagnose per the applicable Service Manual. • If the oil pressure warning light is ON and oil pressure is within standard specification, diagnose per the applicable Service Manual.

STEP 2 ) Remove the oil pressure switch. STEP 3 ) Install the oil pressure gauge (498575400) tool into the oil pressure switch port in the chain cover. STEP 4 ) Reconnect the ground cable terminal to battery sensor and torque to 7.5 Nm (5.5ft.-lbs. or 66 inch-lbs.) while supporting the senor with the other hand: STARTING / CHARGING SYSTEMS > Battery Sensor. STEP 5 ) Start the engine, and check the oil pressure. Engine oil pressure: At Idle (in Neutral or Park): Standard • Refer to the chart below for pressure specification. At 3,000 RPM: Standard • Refer to the chart below for pressure specification.
