Honda HR-V: Cylinder Bore Honing


1. Oil Jet - Remove

2. Cylinder Bore - Honing

Engine Control System & Engine Mechanical - Testing & Troubleshooting

  1. Measure the cylinder bores. If the engine block is to be reused, hone the cylinders and remeasure the bores. Only scored or scratched cylinder bore must be honed.
  2. Hone the cylinder bores with honing oil and a fine (400 grit) stone.

Honing Pattern: Within 30-60 degree cross-hatch pattern (A)


  • Use only a rigid hone with 400 grit or finer stone such as Sunnen, Ammco, or equivalent.
  • Do not use stones that are worn or broken.
  1. When honing is complete, thoroughly clean the engine block of all metal particles. Wash the cylinder bores with hot soapy water, then dry and oil them immediately to prevent rusting. NOTE : Never use solvent, it will only redistribute the grit on the cylinder walls
  2. If scoring or scratches are still present in the cylinder bores after honing to the service limit, rebore the engine block. Some light vertical scoring and scratching is acceptable if it is not deep enough to catch your fingernail and does not run the full length of the bore.

3. All Removed Parts - Install

  1. Install the parts in the reverse order of removal.



NOTE: After this inspection, you must reset the PCM. Otherwise, the PCM will continue to stop the injectors from operating.

1. Engine - Warm Up

  1. Start the engine. Hold the engine speed at 3, 000 rpm with no load (M/T in neutral, CVT in P or N) until the radiator fan comes on, then let it idle.

2. HDS DLC - Connect

NOTE: For specific operations, refer to the user's manual that came with the HDS. Make sure the HDS is loaded with the latest software.

  1. Turn the vehicle to the OFF (LOCK) mode.
  2. Connect the HDS to the DLC.
  3. Turn the vehicle to the ON mode.
  4. Make sure the HDS communicates with the vehicle. If it does not communicate, go to the DLC circuit troubleshooting.


  1. Select ALL INJECTORS STOP in the PGM-FI INSPECTION menu with the HDS
  2. Turn the vehicle to the OFF (LOCK) mode.

4. Ignition Coil and Spark Plug - Remove

5. Engine Compression - Inspect

Engine Control System & Engine Mechanical - Testing & Troubleshooting

  1. Attach a compression gauge to the spark plug hole
  2. Step on the accelerator pedal to open the throttle fully, then crank the engine with the starter motor, and measure the compression.

Above 880 kPa (8.97 kgf/cm2, 127.6 psi)

  1. Measure the compression on the remaining cylinders.

Maximum Variation

Within 200 kPa (2.04 kgf/cm2, 29.0 psi)

  1. If the compression is out of specifications, perform a cylinder leak down test to determine the problem area. Then check the following items, and remeasure the compression:
    • Incorrect valve clearance
    • Confirmation of camshaft timing
    • Damaged or worn cam lobes
    • Damaged or worn valves and seats
    • Damaged cylinder head gasket
    • Damaged or worn piston rings
    • Damaged or worn piston and cylinder bore
  2. Remove the compression gauge from the spark plug hole.

6. Ignition Coil and Spark Plug - Install


  1. Select PCM reset in the PGM-FI system to cancel ALL INJECTORS STOP with the HDS.



1. Oil Jet and Oil Jet Bolt - Remove

2. Engine Oil Jet and Oil Jet Bolt - Inspect

Engine Control System & Engine Mechanical - Testing & Troubleshooting

  1. Inspect the oil jet and the oil jet bolt as follows:
    • Make sure that a 1.0 mm (1/32 in) diameter drill bit will go through the nozzle hole (A) (1.2 mm (0.047 in) diameter).
    • Insert the other end of a 0.8 mm (1/32 in) drill bit into the oil intake (1.0 mm (0.039 in) diameter). Make sure the check ball (B) moves smoothly and has a stroke of about 4.0 mm (0.157 in).
    • Check the oil jet bolt operation with an air nozzle. It should take at least 310 kPa (3.16 kgf/cm2, 45.0 psi) to unseat the check ball.

3. All Removed Parts - Install

  1. Install the parts in the reverse order of removal.


     Idle Speed Inspection

    Inspection NOTE: Before checking the idle speed, check these items: The malfunction indicator lamp (MIL) has not been reported on, and there are no DTCs. Spark plugs Air cleaner PCV syste

     Valve Clearance Adjustment

    Adjustment NOTE: Connect the HDS to the DLC, and monitor ECT SENSOR 1. Adjust the valve clearance only when the engine coolant temperature is less than 100ºF (38ºC). 1. Cylinder Head Cover - Re

     A/C Signal Circuit Troubleshooting (KA)

    NOTE: Do not use this troubleshooting procedure if any of the following items are operative with the A/C button and the fan control dial ON: The A/C condenser fan, the radiator fan, or the A/C compressor. Refer to the symptom troubleshooting index - Refer to: Heating and A/C Systems Symptom

     DTC Troubleshooting B0096-87: No Signal From the Right Side Impact Sensor (First)

    NOTE: Before doing this troubleshooting procedure, find out if the vehicle was in a collision. If so, verify that all the required components were replaced with new components of the correct part number, and that they were properly installed. Before doing this troubleshooting procedure, rev
