Honda HR-V: VTEC System Oil Pressure Troubleshooting
Special Tools Required
- Pressure Gauge Adapter 07NAJ-P07010A
- A/T Low Pressure Gauge w/Panel 07406-0070301
- A/T Pressure Test Hose 07AAJ-PY4A100
- A/T Pressure Adapter 07MAJ-PY40120
- Oil Pressure Hose 07ZAJ-S5AA200
NOTE:
- Check that the oil level is correct and that the oil pressure indicator
goes off after starting engine before
this procedure.
- Check for Pending DTCs or DTCs with the HDS before this procedure. If
there are any DTCs indicated,
troubleshoot them first, then do this procedure.
1. VTEC system operation check (with HDS).
- Turn the vehicle to the ON mode.
- Select the VTEC TEST in the INSPECTION MENU with the HDS.
VTEC TEST
Can you hear the rocker arm oil control solenoid click?
YES
Go to step 3.
NO
Go to step 2.
2. Rocker arm oil control solenoid operation check.
- Turn the vehicle to the OFF (LOCK) mode.
- Disconnect the following connector.
Rocker arm oil control solenoid 2P connector
- At the solenoid side, connect terminals A and B with a jumper wire.
Is the rocker arm oil control solenoid clicking?
YES
The rocker arm oil control solenoid is OK. Update the PCM if it does not have
the latest software, or substitute a known-good PCM.
NO
Failure in the rocker arm oil control solenoid. Replace the rocker arm oil
control valve.
3. VTEC system oil pressure check.
- Turn the vehicle to the OFF (LOCK) mode.
- Remove the bolt (A) from the rocker arm oil control valve, and attach
the special tools as shown, then
attach the bolt that was removed to the oil pressure gauge adapter (B).
- Start the engine. Hold the engine speed at 3, 000 rpm without load (CVT
in P or N, M/T in neutral)
until the radiator fan comes on.
- Check the VTEC oil pressure at the engine speed of 1, 000 to 2, 000 rpm.
NOTE: Keep the measuring time as short as possible (less than 1 minute).
Is the oil pressure below 49 kPa (0.5 kgf/cm2, 7 psi)
YES
VTEC system oil pressure is OK. Go to step 4.
NO
Failure in spool valve (stuck open). Replace the rocker arm oil control
valve.
4. Rocker arm oil control solenoid operation check.
- Turn the vehicle to the OFF (LOCK) mode.
- Disconnect the following connector.
Rocker arm oil control solenoid 2P connector
- At the solenoid side, connect terminals A and B with a jumper wire.
- Start the engine.
- Check the VTEC oil pressure at the engine speed of 3, 500 rpm.
NOTE: Keep the measuring time as short as possible (less than 1 minute).
Is the oil pressure above 390 kPa (4.0 kgf/cm2, 57 psi)
YES
The VTEC system oil pressure and the rocker arm oil control solenoid are OK.
NO
The oil pressure is lower than normal condition. Go to step 5.
5. Rocker arm oil control valve filter visual check.
- Remove the rocker arm oil control valve.
- Check the rocker arm oil control valve filter for dirt and clogging.
Is the rocker arm oil control valve filter dirty or clogged?
YES
Replace the engine oil, the engine oil filter, and the rocker arm oil
control valve with new rocker arm oil control valve filter.
NO
Failure in spool valve (stuck closed). Replace the rocker arm oil control
valve.
