Toyota Corolla (E120): Evap monitor (vacuum pressure monitor)

Notice

: a cold soak must be performed prior to conducting the drive pattern to complete the internal pressure readiness monitor.

  1. Cold soak preconditions

The monitor will not run unless:

  • mil is off.
  • Fuel level is approximately 1/2 to 3/4.
  • Altitude is 7800 feet (2400 m) or less.
  1.  cold soak procedure

Let the vehicle cold soak for 8 hours or until the difference between iat and ect becomes less than 13°f (7 °C).

Hint

: examples:

  • scenario 1
    ect = 75°f (24 °C)
    iat = 60°f (16 °C)
    difference between ect and iat is 15°f (8 °C).

    The monitor will not run because difference between ect and iat is greater than 13°f (7 °C).

  • Scenario 2
    ect = 70°f (21 °C)
    iat = 68°f (20 °C)
    difference between ect and iat is 2°f (1 °C).

    The monitor will run because difference between ect and iat is less than 13°f (7 °C).
