1. Check the engine oil level. Is the level OK? YES- Go to step 2 . NO- Adjust the engine oil to the proper level, then go to step 14 . 2. Turn the ignition switch ON (II). 3. Clear the DTC with the HDS. 4. Do the VTEC TEST in the INSPECTION MENU with the HDS. Is the result OK? YES- Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the rocker arm oil pressure switch (VTEC oil pressure switch) and the ECM/PCM. NO- Go to step 5 . 5. Check the result of step 4 . Rocker Arm Oil Pressure Switch (VTEC Oil Pressure Switch) Failure Rocker Arm Oil Pressure Switch (VTEC Oil Pressure Switch) Open Rocker Arm Oil Pressure Switch (VTEC Oil Pressure Switch) SIG Line Open Rocker Arm Oil Pressure Switch (VTEC Oil Pressure Switch) GND Line Open Is the test result any of the above? YES- Go to step 6 . NO- Check for poor connections or loose terminals at the rocker arm oil pressure switch (VTEC oil pressure switch). If it is OK, replace the rocker arm oil control solenoid (VTEC solenoid valve) (see step CMP SENSOR A REPLACEMENT ), then go to 14 . 6. Turn the ignition switch OFF. 7. Disconnect the rocker arm oil pressure switch (VTEC oil pressure switch) 2P connector. 8. Check for continuity between rocker arm oil pressure switch (VTEC oil pressure switch) 2P connector terminals No. 1 and No. 2.

NOTE: 1. Release fuel pressure. See FUEL SYSTEM PRESSURE RELEASE . Install a fuel pressure gauge between fuel pressure regulator and fuel distributor pipe. See Fig. 1 . Bleed air from fuel line going to pressure gauge. 2. Unplug fuel pressure regulator Vacuum Switching Valve (VSV) connector on right side fender skirt. This is a 4-wire connector with Black and Blue wires in harness. PCM controls VSV to cut vacuum to fuel pressure regulator during hot engine starts. 3. Start engine and measure fuel pressure at idle. Disconnect fuel pressure regulator vacuum hose. Note fuel pressure at idle with vacuum hose disconnected (no vacuum). Fuel pressure should be 42 psi (3.0 kg/cm2 ). See FUEL PUMP PERFORMANCE . 4. If fuel pump pressure is low, check for fuel leaks, restrictions in intake side of fuel pump, leaking injectors, faulty pressure regulator or faulty fuel pump. If fuel pressure is high, check for restrictions in return line to tank or faulty pressure regulator. If pressure does not change when pressure regulator is disconnected, replace pressure regulator. 5. Reconnect pressure regulator vacuum hose and check fuel pressure (with vacuum). Fuel pressure should be 35 psi (2.4 kg/cm2 ). Apply battery voltage to VSV connector Blue wire terminal, and ground Black wire terminal (with vacuum). See Fig. 2 . Fuel pressure gauge should read about 42 psi (3.0 kg/cm2 ). If fuel pressure is not within specification, check for defective VSV. 6. Disconnect and plug vacuum hose from fuel pressure regulator. Stop engine and ensure fuel pressure remains greater than 35 psi (2.4 kg/cm2 ) for 4 minutes after engine stops. 7. If pressure drops, check for leaking injectors, faulty pressure regulator or bad check valve in fuel pump. If engine does not start, by-pass fuel pump relay to check for fuel pressure. Remove fuel pump relay from underhood fuse/relay box. Connect a fused jumper wire between terminals No. 1 and 3 of fuel pump relay connector in fuse block. See Fig. 3 and Fig. 4 . 8. If fuel pump does not operate, check for battery voltage to terminal No. 3. If battery voltage is present, check for open in fuel pump circuit. If fuel pump operates with jumper wire installed, check fuel pump relay and relay energizing circuit. Repair as necessary. Begin basic fuel system diagnosis with testing fuel pressure.

1. 2. 3. 4. 5. Raise and support the vehicle. Refer to Vehicle Lifting. Position the oil drain pan under the engine oil drain plug. Remove the engine oil drain plug. Clean and inspect the engine oil drain plug, repair or replace if necessary. Clean and inspect the engine oil drain plug sealing surface on the oil pan, repair or replace oil pan if necessary. 6. Remove the oil filter. 7. Clean and inspect the oil filter sealing area on the engine block, repair or replace if necessary. Installation Procedure 1. Lightly oil the replacement oil filter gasket with clean oil and install the new oil filter. Notice: Refer to Fastener Notice in Service Precautions. 2. Install the new oil filter. Tighten the new oil filter to 3/4 to 1 full turn, after the oil filter gasket contacts the oil filter mounting surface. 3. Install the engine oil drain plug. Tighten the plug to 30 Nm (22 ft. lbs.) . 4. 5. 6. 7. 8. 9. Remove the oil drain pan. Lower the vehicle. Fill the engine with new engine oil. Start the engine. Inspect for oil leaks after engine start up. Turn off the engine and allow the oil a few minutes to drain back into the oil pan. Remove the oil level indicator from the oil level indicator tube. Clean off the indicator end of the oil level indicator with a clean paper towel or cloth. Install the oil level indicator into the oil level indicator tube until the oil level indicator handle contacts the top of the oil level indicator tube. Again, remove the oil level indicator from the oil level indicator tube keeping the tip of the oil level indicator down. Check the level of the engine oil on the oil level indicator. If necessary, adjust the oil level by adding or draining the engine oil. 10. 11. 12. 13. 14. 15.

NOTE: Numbers in parentheses ( ) indicate a component or tool in the associated illustration. WARNING: Risk of Injury to skin or eyes due to hydraulic fluid spraying out under high pressure Risk of poisoning due to consuming hydraulic fluid NOTE: Before starting work on the hydraulic system, depressurize the system Wear protective clothing and safety gasses 1. Empty pressure oil system at rear axle 2. Connect tester to rear axle connecting piece (57) 3. Pour suitable oil into oil reservoir (2) NOTE: For testing, increase the quantity of oil to approx. 0.5 liters above the “max. ” marking (a) on the oil dipstick (2a) 4. Disconnect return (flow) line (T) at oil reservoir (2), connect oil drain hose (061) to the return (flow) line (T) and guide into oil reservoir (2) Pay attention to secure hose routing When the pressure relief valve in the valve unit opens, the oil pressure in the return (flow) line increases to approx. 2 bar 5. Connect Hand-Held Tester (HHT) (089) part No. 65 11 0001 99, or equivalent, with suitable test cable (094) to data link connector (X11/4) WARNING: Risk of accident due to vehicle starting off automatically when engine is running Risk of injury due to being trapped and burns when intervening while starting the engine or when the engine is running 6. Start engine and allow to idle WARNING: Secure vehicle to prevent it from starting off automatically Wear close-fitting, tight clothing Do not touch hot or rotating parts 7. Place HHT (089) in “lift” position NOTE: Only carry out the test briefly due to the high pressures. The delivery pressure of the pressure oil pump is limited by the bypass valve in the valve unit 8. Check opening pressure of bypass valve Delivery pressure at engine idle speed: 180-190 bar 9. Check delivery rate of pressure oil pump: Connect oil drain hose (061) to the return (flow) line (T) in a measuring vessel Ensure that there is sufficient oil in the oil reservoir. The pump must not draw in air under any circumstances Delivery rate at engine idle speed: 0.2 liters/min

1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to Section 100-00. 2. If oil pump removal is necessary, remove the timing drive components. For additional information, refer to Timing Drive Components in this section. 3. Drain the engine oil. 4. If equipped, remove the skid plate. 5. Remove the bolts in sequence shown and remove the crossmember. 6. Remove the parts in the order indicated in the following illustrations and tables. To remove individual parts, only carry out the listed steps: 7. To install, reverse the removal procedure. Item 1: Front Drive Axle Assembly Removal Note 1. Position a suitable hydraulic jack under the front axle. Securely strap the jack to the axle. 2. NOTE: Rotate the steering column so the pinch bolt for the steering column coupling allows clearance for the isolator bolt. Remove the upper front axle carrier mounting bushing bolt. 3. Remove the axle shaft housing carrier bushing bolt. 4. Remove the lower front axle carrier mounting bushing bolt. 5. Partially lower the front axle assembly. Item 4: Oil Pan Removal Note 1. NOTICE: Do not use metal scrapers, wire brushes, power abrasive discs, or other abrasive means to clean the sealing surfaces. These may cause scratches and gouges resulting in leak paths.
