• Power Steering Pump
  Standard fluid pressure:
  7,800 to 8,300 kPa (80 to 85 kgf/cm2, 1,131 to 1,204 psi)
  Standard fluid temperature:
  75 to 80°C (167 to 176°F)

• Fuel Pressure Regulator Located in Fuel Tank
  REMOVE FUEL PRESSURE REGULATOR
  ASSEMBLY
  (a) Pull the fuel pressure regulator out of the fuel tank
  fuel filter.
  (b) Remove the O-ring from the fuel pressure regulator.

• IAT malfunction can put ECM into "SAFE MODE" operation (aka limp mode).
  
  MONITOR DESCRIPTION
  The ECM monitors the sensor voltage and uses this value to calculate the Intake Air Temperature (IAT).
  When the sensor output voltage deviates from the normal operating range, the ECM interprets this as a
  malfunction in the IAT sensor and sets a DTC.
  Example:
  If the sensor output indicates -40°C (-40°F) for 0.5 seconds or more, the ECM determines that there is an
  open in the IAT sensor circuit, and sets DTC P0113. Conversely, if the sensor output indicates more than
  140°C (284°F) for 0.5 seconds or more, the ECM determines that there is a short in the sensor circuit, and
  sets DTC P0112.
  If the malfunction is not repaired successfully, a DTC is set 0.5 seconds after the engine is next started.

• Purge Vacuum Switching Valve
  
  1. INSPECT VACUUM SWITCHING VALVE ASSEMBLY
  (for EVAP)
  
  (a) Measure the resistance of the purge VSV.
  Standard resistance
  Tester Connection Specified Condition
  1 - 2 30 to 34 Ω at 20°C (68°F)
  1 - Body ground
  2 - Body ground
  10 MΩ or higher
  If the result is not as specified, replace the purge
  VSV.
