POWER ASSISTED SYSTEM (POWER STEERING)
3. HYDRAULIC PRESSURE
NOTE:
• To measure hydraulic pressure correctly, be
sure to complete all the items in “INSPECTION”,
prior to performing the measurement. <Ref. to PS-
51, INSPECTION, General Diagnostic Table.>
• Do not leave the valve of pressure gauge closed
or hold the steering wheel at lock for 5 seconds or
more in any case, this can damage the oil pump.
• Before attaching a pressure gauge, place cloth
at locations where fluid is expected to spill. Wipe off
any spilt fluid completely after the measurement.
1) Regular pressure measurement
(1) Connect the ST1, ST2 and ST3.

(2) Remove the air intake duct.
(3) Disconnect the pipe C from pump.
(4) Using the gasket (Part No. 34621AC021)
and bolt (Part No. 34620AC010), install the ST2
to pump instead of pressure hose.
• Non-turbo model
• Turbo model
(5) Attach the ST3 to the end of pressure hose
which is removed from pump.
(6) Replenish power steering fluid up to the
specified level.
(7) Open the valve, and start the engine.
(8) Measure the regular pressure.

(9) If it is not within the specification, replace the
problem part for the following problems. (Pipe
or hose clogged, leaks from fluid line, and mix-
ture of foreign matter in fluid line)
2) Measure the relief pressure.
(1) Using the STs, measure the relief pressure.
(2) Close the valve.
(3) Measure the relief pressure.
