Honda HR-V: APP Sensor Signal Inspection

Inspection

NOTE:

• This procedure checks the APP sensor in its fully closed position. In any other position, the APP sensor stores DTCs which are covered in other troubleshooting procedures.
• Check for Pending or Confirmed DTCs with the HDS before doing this procedure. If any DTCs are indicated, troubleshoot them first, then do this procedure.
• Press the accelerator pedal several times, to check its operation. If it does not operate smoothly, check the pedal. If you find a problem, replace the accelerator pedal module.

1. HDS - Connect

2. APP Sensor Signal - Inspect

1. Make sure the accelerator pedal is not pressed, then check the APP SENSOR in the DATA LIST with the HDS.
   • If it is 0 %, the APP sensor is OK.
   • If it is not 0 %, update the PCM if it does not have the latest software, or substitute a known-good PCM, then go to step 2.
2. Make sure the accelerator pedal is not pressed, then check the APP SENSOR in the DATA LIST with the HDS.
   • If it is 0 %, the APP sensor is OK.
   • If it is not 0 %, replace the accelerator pedal module, then go to step 1.

BLOCK AND PISTON INSPECTION

Inspection

1. Crankshaft - Remove

2. Piston - Remove

3. Piston - Inspect

1. Check the pistons for distortion or cracks
2. Measure the piston skirt diameter (A) at a point 14 mm (0.55 in) from the bottom of the skirt.

Standard (New): 80.980-80.990 mm (3.18818-3.18858 in)
Service Limit: 80.93 mm (3.1862 in)
0.25: 81.230-81.240 mm (3.19803-3.19842 in)

4. Block - Inspect

1. Measure the wear and taper in direction X and Y at three levels in each cylinder as shown. If the measurements in any cylinder are beyond the oversize bore service limit, replace the engine block. If the engine block has to be rebored, check the piston-tocylinder bore clearance.

Cylinder Bore Size

Standard (New):

Direction X: 81.000-81.020 mm (3.18897-3.18976 in)
Direction Y: 81.000-81.015 mm (3.18897-3.18956 in)
Service Limit: 81.070 mm (3.19173 in)
0.25: 81.250-81.265 mm (3.19881-3.19940 in)
Reboring limit: 0.25 mm (0.0098 in) max.
Limit: (Difference between first and third measurement) 0.050 mm (0.00197 in)

2. Hone any scored or scratched cylinder bores if needed.

3. Check the top of the engine block for warpage.

   Measure along the edges and across the center as shown.

Standard (New): 0.07 mm (0.002 in) max.

5. Piston-to-Cylinder Clearance - Inspect

1. Calculate the difference between the cylinder bore diameter and the piston diameter. If the clearance is near or exceeds the service limit, inspect the piston and the cylinder bore for excessive wear.

Standard (New): 0.010-0.035 mm (0.00039-0.00138 in)
Service Limit: 0.05 mm (0.0020 in)

6. All Removed Parts - Install

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