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.
- 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.
- 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).

Manual shifting test
1. Perform manual shifting test
Hint:
by this test, it can be determined whether the trouble is within
the electrical circuit or is a mechanical problem in the transaxle.
Disconnect the transmission wire connector.
inspect the manual driving operation.
Check that the shift and g ...
Check short circuit
If the wire harness is ground shorted as shown in fig. 5,
Locate the section by conducting a resistance check with
the body ground in step (b).
Check the resistance with the body ground.
Disconnect connectors a and c and measure the
resistance between terminals 1 and 2 ...
Inspection procedure
Hint:
if different dtcs related to different systems that have terminal e2
as the ground terminal are output
simultaneously, terminal e2 may be open.
