Special Tools Required

Bypass tube joint 07406-0010101 (Included with 07406-0010001 or 07406-001000A)

1. Check the power steering fluid level, seeFLUID REPLACEMENT  and pump belt tension, see PUMP BELT INSPECTION AND ADJUSTMENT  .
2. Start the engine, let it idle, and turn the steering wheel from lock-to-lock several times to warm up the fluid.
3. Stop the engine, to simulate speeds above 62 mph (100 km/h), disconnect the sensor inlet hose (A) and sensor outlet hose (B) from the power steering speed sensor (C), and connect them to the bypass tube joint (D). Plug (E) the end of the bypass tube joint (The vehicle speed pulse connector is only on vehicles equipped with the navigation system).

4. Attach a commercially available spring scale to the steering wheel. Start the engine, with the idling and 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 more than 25 N (2.5 kgf, 5.5 lbf) the valve body unit is OK. The problem is in the power steering speed sensor, replace it , see POWER STEERING SPEED SENSOR REPLACEMENT  and road test.
   • If the scale reads 25 N (2.5 kgf, 5.5 lbf) or less, problem is in the pump. Check the PUMP PRESSURE TEST WITH T/N 07406-0010001  or PUMP PRESSURE TEST WITH T/N 07406-001000A  .
