Symptom Troubleshooting Index

Find the symptom in the chart below, and do the related procedures in the order listed until you find the cause.

SymptomProcedure(s)Also check for
Hard steeringTroubleshoot the system (see SYMPTOM TROUBLESHOOTING ).Modified suspension Tire sizes, tire varieties, and air pressure
Assist (excessively light steering at high speed)Check the rack guide adjustment (see RACK GUIDE ADJUSTMENT ).Front wheel alignment (see WHEEL ALIGNMENT ) Tire pressure
Shock or vibration when the steering wheel is turned to full lockCheck the rack guide adjustment (see RACK GUIDE ADJUSTMENT ). Check the drive belt for slippage (see DRIVE BELT REPLACEMENT ). Overhaul the steering gearbox (see STEERING GEARBOX OVERHAUL ).
Steering wheel will not return smoothlyCheck cylinder lines for deformation. Check wheel alignment (see WHEEL ALIGNMENT ). Overhaul the steering gearbox (see STEERING GEARBOX OVERHAUL ).
Uneven or rough steeringCheck the rack guide adjustment (see RACK GUIDE ADJUSTMENT ). Check the drive belt (see DRIVE BELT REPLACEMENT ). Check for a low or erratic engine idle speed (see ECM/PCM IDLE LEARN PROCEDURE ). Check for air in the power steering system due to low fluid level or an air leak at the pump inlet hose. Check for low fluid level in the power steering reservoir due to possible leaks in system. Overhaul the steering gearbox (see STEERING GEARBOX OVERHAUL ).
Steering wheel kicks back during wide turnsCheck the drive belt (see DRIVE BELT REPLACEMENT ). Check the power steering pump fluid pressure with T/N 07406-0010001 (see PUMP PRESSURE TEST WITH T/N 07406-0010001 ), or T/N 07406-001000A (see PUMP PRESSURE TEST WITH T/N 07406-001OOOA ).
Humming noise from the power steering systemCheck when the noise occurs: If the noise is heard 2 to 3 minutes after starting the engine in cold weather, this is normal. If the noise is heard when the wheel is turn with the vehicle stopped, this is normal due to the fluid pulsation. Check for the high-pressure hose touching the subframe or body. Check for automatic transmission converter noise. Check for air bubbles in the power steering fluid, or an air leak on inlet side of the pump. Check for particle contamination of fluid and a restricted filter in the reservoir.Power steering pump fluid pressure
Power steering rack rattle or chatteringCheck for loose steering components (tie-rod end ball joints). Tighten or replace as necessary. Check the steering column shaft for wobbling. If the steering column wobbles, replace the steering column assembly (see STEERING COLUMN REMOVAL AND INSTALLATION ). Check the rack guide adjustment (see RACK GUIDE ADJUSTMENT ). Check the power steering pump pulley. If the pulley is loose, tighten it (see step 47 ). If the pump shaft is loose, replace the pump (see PUMP REPLACEMENT ).
Hissing noise/foaming fluid in reservoirCheck the fluid level. If low, fill the reservoir to the proper level and check for leaks. Check the reservoir for leaks. Check for a crushed inlet hose or loose hose clamp allowing air into the suction side of the system. Check the power steering pump shaft oil seal for leaks.
Noise from the power steering pumpCompare the pump noise at normal operating temperature to another like vehicle (pump noise up to 2-3 minutes after starting the engine in cold weather is normal). Remove and inspect the pump for wear and damage (see PUMP OVERHAUL ).

Fluid leaks from the boot A: Replace the valve oil seal on the pinion shaft. Replace the cylinder end seal on the gearbox side. Fluid leaks from boot B: Replace the left cylinder end seal. Fluid leaks from pinion shaft near the lower steering joint bolt: Overhaul the valve body unit.
Fluid leaks from the power steering lineFluid leaks from the cylinder line connections (flare nuts): Tighten the connection and retest. Fluid leaks from damaged cylinder lines: Replace the cylinder line. Fluid leaks from the pump outlet hose or return line fitting on the valve body unit (flair nuts): Tighten the fitting and retest. If it still leaks, replace the hose, the line, or valve body unit as necessary.
Fluid leaks from the power steering pumpFluid leaks from the front oil seal: Replace the front oil seal. Fluid leaks from the power steering pump housing: Replace the leaking O-rings or seals (see PUMP OVERHAUL ), and if necessary, replace the power steering pump (see PUMP REPLACEMENT ).

Scheme 3

Scheme 3: 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. If the play is within the limit, the gearbox and linkages are OK. If the play exceeds the limit, adjust the rack guide (see «RACK GUIDE ADJUSTMENT»(/acura/rsx/i-2001-2004/remont/manual-power-steering/#power-steering-system__rack-guide-adjustment) ). If the play is still excessive after rack guide adjustment, inspect the steering linkage and gearbox (see «STEERING LINKAGE AND GEARBOX INSPECTION»(/acura/rsx/i-2001-2004/remont/manual-power-steering/#power-steering-system) ). Rotational play: 0-10 mm (0-0.39 in.)

Power Assist Check

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

Scheme 4

Scheme 4: Power Assist Check
  1. Check the power steering fluid level (see «FLUID REPLACEMENT»(/acura/rsx/i-2001-2004/remont/manual-power-steering/#power-steering-system__fluid-replacement) ).
  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. If the scale reads no more than specifications, the gearbox and pump are OK. If the scale reads more than specifications, troubleshoot the steering system (see «SYMPTOM TROUBLESHOOTING»(/acura/rsx/i-2001-2004/remont/manual-power-steering/#power-steering-system) ). Initial turning load: K20A2 engine, K20Z1 engine models: 38.2 N (3.9 kgf, 8.6 lbf) K20A3 engine model: 37.2 N (3.8 kgf, 8.4 lbf)
