Low Oil Pressure Indicator Does Not Come On With the Ignition Switch In ON (II)

  1. Connect the Honda Diagnostic System (HDS) to the data link connector (DLC) (see step 2 on «HOW TO USE THE HDS (HONDA DIAGNOSTIC SYSTEM)»(ref-333557-S21912312122009072100000) ).
  2. Turn the ignition switch to ON (II).
  3. Make sure the HDS communciates with the vehicle and the powertrain control module (PCM). If it does ot communciate, troubleshoot the DLC circuit (see «DLC CIRCUIT TROUBLESHOOTING»(ref-333558-S02093989162009072100000) ).
  4. Check for DTC's (see «HOW TO USE THE HDS (HONDA DIAGNOSTIC SYSTEM)»(ref-333557-S21912312122009072100000) ). If the DTC is present, diagnose, and repair the cause before continuing with this test.
  5. Do the gauge control module self-diagnostic function (see «SELF-DIAGNOSTIC FUNCTION»(ref-333620-S02042375952009072100000) ). Is the gauge control module OK? YES - Go to step 3 . NO - Replace the gauge control module (see «GAUGE CONTROL MODULE REPLACEMENT»(ref-333620-S12421720222009072100000) ).
  6. Completely opens the throttle.
  7. Check the MAP SENSOR and BARO SENSOR in the DATA LIST with the Honda Diagnostic System (HDS). MAP SENSOR-BARO SENSOR = "A" Is "A" 19.9 kPa (0.20 kgf/cm 2 , 2.89 psi) or less? YES - Go to step 5 . NO - Replace the powertrain control module (PCM) (see «PCM REPLACEMENT»(ref-333558-S09775742392009072100000) ).
  8. Check the ROCKER ARM OIL PRESSURE SENSOR in the DATA LIST with the HDS. Is It the 19.0 kPa (0.19 kgf/cm 2 , 2.76 psi) or less? YES - Update the PCM (see «PCM UPDATE»(ref-333558-S24141467512009072100000) ) if it does not have the latest software, or substitute a known-good PCM (see «SUBSTITUTING THE PCM»(ref-333557-S35070474232009072100000) ), then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM (see «PCM REPLACEMENT»(ref-333558-S09775742392009072100000) ). • NO - Replace the rocker arm oil pressure sensor (see «ROCKER ARM OIL PRESSURE SENSOR REPLACEMENT»(ref-333553-S07711296432009072100000) ).

  1. Connect the Honda Diagnostic System (HDS) to the data link connector (DLC) (see step 2 on «HOW TO USE THE HDS (HONDA DIAGNOSTIC SYSTEM)»(ref-333557-S21912312122009072100000) ).
  2. Turn the ignition switch to ON (II).
  3. Make sure the HDS communicates with the vehicle and the powertrain control module (PCM). If it does not communicate, troubleshoot the DLC circuit (see «DLC CIRCUIT TROUBLESHOOTING»(ref-333558-S02093989162009072100000) ).
  4. Check for DTCs (see «HOW TO USE THE HDS (HONDA DIAGNOSTIC SYSTEM)»(ref-333557-S21912312122009072100000) ). If a DTC is present, diagnose, and repair the cause before continuing with the test.
  5. Check the engine oil level. Is the engine oil level normal? YES - Go to step 6. NO - Add engine oil to bring the oil level up to normal, then recheck.
  6. Remove the rocker arm oil pressure sensor cover (see step 1 ).
  7. Remove the rocker arm oil pressure sensor (see «ROCKER ARM OIL PRESSURE SENSOR REPLACEMENT»(ref-333553-S07711296432009072100000) ).
  8. Install the oil pressure hose, the A/T low pressure gauge w/panel, the A/T pressure test hose, and the A/T pressure adapter as shown, then install the rocker arm oil pressure sensor to the pressure gauge adapter.
  9. Warm up the engine.
  10. At the idling of an engine, check the oil pressure gauge value. 70 kPa (0.7 kgf/cm 2 , 10 psi) or less? YES - Go to step 11. NO - Check the following items: • Blocking of oil filter. Blocking of oil strainer. Inspect the oil pressure relief valve (see «Inspection»(ref-333553-S35003097122009072100000) Check the oil pump (see «Installation»(ref-333553-S03164575122009072100000) ).
  11. Check the ROCKER ARM OIL PRESSURE SENSOR in the DATA LIST with the HDS. Is the 19.0 kPa (0.19 kgf/cm 2 , 2.76 psi) or less? YES - Go to step 15 . NO - Go to step 12.
  12. Jump the SCS line with the HDS, then turn the ignition switch to LOCK (0). NOTE: This step must be done to protect the PCM from damage.
  13. Disconnect the PCM connector C (49P).
  14. Turn the ignition switch to ON (II). Does the low oil pressure indicator go off? YES - Update the PCM (see «PCM UPDATE»(ref-333558-S24141467512009072100000) ) if it does not have the latest software, or substitute a known-good PCM (see «SUBSTITUTING THE PCM»(ref-333557-S35070474232009072100000) ), then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM (see «PCM REPLACEMENT»(ref-333558-S09775742392009072100000) ). • NO - Replace the gauge control module (see «GAUGE CONTROL MODULE REPLACEMENT»(ref-333620-S12421720222009072100000) ).
  15. Check the MAP SENSOR and BARO SENSOR in the DATA LIST with the HDS. BARO SENSOR-MAP SENSOR="A" Is "A" 19.9 kPa (0.20 kgf/cm 2 , 2.89 psi) or less? YES - Replace the rocker arm oil pressure sensor (see «ROCKER ARM OIL PRESSURE SENSOR REPLACEMENT»(ref-333553-S07711296432009072100000) ). • NO - Replace the PCM (see «PCM REPLACEMENT»(ref-333558-S09775742392009072100000) ).

  1. Remove the rocker arm oil pressure sensor cover.
  2. Disconnect the rocker arm oil pressure sensor connector, then remove the rocker arm oil pressure sensor.
  3. Apply liquid gasket (P/N 08717-0004, 08718-0003, 08718-0004, or 08718-0009) to the rocker arm oil pressure sensor threads. Install the component within 5 minutes of applying the liquid gasket. NOTE: Using too much liquid gasket may cause liquid gasket to enter the oil passage or the end of the rocker arm oil pressure sensor. If too much time has passed after applying the liquid gasket, remove the old liquid gasket and residue, then reapply the new liquid gasket.
  4. Install the rocker arm oil pressure sensor using a new O-ring.
  5. Connect the rocker arm oil pressure sensor connector.
  6. Install the rocker arm oil pressure sensor cover.
