Toyota Corolla (E120): Evap monitor (vacuum pressure monitor) (continued)
- 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.*
- Engine coolant temperature (ect) is between 40°f and 95°f (4.4 °C and 35 °C).
- Intake air temperature (iat) is between 40°f and 95 °f (4.4 °C and 35 °C).*
- Cold soak procedure has been completed.
- Before starting the engine, the difference between ect and iat must be 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).
Notice
: * note for 2002 and later my vehicles: the readiness test can be completed in cold ambient conditions (less than 40°f / 4.4 °C) and/or at high altitudes (more than 7800 feet / 2400 m) if the drive pattern is repeated a second time after cycling the ignition off.
- Drive pattern
- connect the obd ii scan tool to dlc3 to check monitor status and preconditions.
- Release pressure in the fuel tank by removing and then reinstalling the fuel tank cap.
- Start the engine and allow it to idle until ect becomes 167°f (75 °C) or greater.
- Run the engine at 3,000 rpm for about 10 seconds.
- Allow the engine to idle with the a/c on (to create slight load) for 15 to 50 minutes.
Notice
