Power Steering System: Other Honda CR-V II

Hard Steering

1. Check the power assist (see «Power Assist Check»(ref-171420-S11594818242005020300000) ). Is the starting load more than 29 N (3.0 kgf, 6.6 Ft.Lbs.)? YES - Go to step 2. NO - Power assist is OK.
2. Measure steady-state fluid pressure from the pump at idle with T/N 07406-0010001 (see step 9 on ) or T/N 07406-001000A (see step 8 on ). Is the pressure 1,500 kPa (15 kgf/cm 2 , 213 psi) or less? YES - Go to step 3. NO - Go to step 7 .
3. Measure the pump relief pressure at idle with T/N 07406-0010001 (see step 11 on ) or T/N 07406-001000A (see step 10 on ). Is the pressure 7,460-8,140 kPa (76-83 kgf/cm 2 , 1,080-1,180 psi) or less? YES - Go to step 4. NO - Faulty pump assembly.
4. With a spring scale, measure the power assist in both directions, to the left and to the right. Are the two measurements within 2.9 N (0.3 kgf, 0.66 Ft.Lbs.) of each other? YES - Go to step 5. NO - Go to step 8 .
5. Measure the fluid pressure with T/N 07406-0010001 (see step 12 on ) or with T/N 07406-001000A (see step 11 on ) with both pressure gauge valves open (if so equipped), while turning the steering wheel fully to the left and fully to the right. Is the pressure 7,460-8,140 kPa (76-83 kgf/cm 2 , 1,080-1,180 psi) or less? YES - Go to step 6. NO - Faulty gearbox.
6. Adjust the rack guide (see «Rack Guide Adjustment»(ref-171420-S19376066852005020300000) ), and retest. Is the steering OK? YES - Repair is completed. NO - Faulty gearbox.
7. Check the feed and return lines between the pump and the gearbox for clogging and deformation. Are the lines clogged or deformed? YES - Repair or replace the lines. NO - Faulty valve body unit or pump.
8. Check the cylinder lines for deformation (see «Fluid Leakage Inspection»(ref-171420-S12641784522005020300000) ) Are the lines deformed? YES - Replace the lines. NO - Go to step 9.
9. Check for a bent rack shaft or misadjusted rack guide (too tight).

Is the rack shaft bent or the rack guide adjusted too tight?

1. YES - Replace the steering gearbox or readjust the rack guide.
2. NO - Faulty valve body unit.

Steering Wheel Rotational Play Check

1. Turn the front wheels to the straight ahead position.
2. Measure how far you can turn the steering wheel left and right without moving the front wheels.

Scheme 143

1. If the play is within the limit, the gearbox and linkages are OK.
2. If the play exceeds the limit, adjust the rack guide (see «Rack Guide Adjustment»(ref-171420-S19376066852005020300000) ). If the play is still excessive after rack guide adjustment, inspect the steering linkage and gearbox (see «Steering Linkage and Gearbox Inspection»(ref-171420-S37285697802005020300000) ).

Power Assist Check

Note. This test should be done with original equipment tires and wheels at the connect tire pressure.

1. Check the power steering fluid level (see «Fluid Replacement»(ref-171420-S35109618852005020300000) ).
2. Start the engine, let it idle, and turn the steering wheel from lock-to-lock several times to warm up the fluid.
3. Attach a commercially-available spring scale to the steering wheel. With the engine idling and the vehicle on a clean, dry floor, pull the scale as shown and read it as soon as the tires begin to turn.

Scheme 144

1. If the scale reads no more than specifications, the gearbox and pump are OK.
2. If the scale reads more than specifications, troubleshoot the steering system (see «Symptom Troubleshooting»(ref-171420-S02729531102005020300000) ).
