Check for the evaporative emission ventilation solenoid
connector D-116 (terminal No. 1) and ground.
⦆
Not continuity.
Q:Is the harness wire in good condition?
YES:
Go to Step 6.
NO:
Repair it. Then go to Step 7.
STEP 6. Check the trouble symptoms.
(1)
Carry out a test drive with the drive cycle pattern. Refer to
Diagnostic Function - OBD-II Drive Cycle - Pattern 24 P.
13Ab-8.
(2)
Check the diagnostic trouble code (DTC).
Q:Is DTC P0446 set?
YES:
Replace the ECM. When the ECM is replaced, register
the ID code. Refer to GROUP 42B, ID Code Registration
Judgment Table <Vehicles with KOS> P.42B-12or GROUP
42C, ID Code Registration Judgment Table <Vehicles with
WCM> P.42C-8. Then go to Step 7.
NO:
It can be assumed that this malfunction is
intermittent. Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points - How to Cope
with Intermittent Malfunctions P.00-15.
STEP 7. Test the OBD-II drive cycle.
(1)
Carry out a test drive with the drive cycle pattern. Refer to
Diagnostic Function - OBD-II Drive Cycle - Pattern 24 P.
13Ab-8.

DIAGNOSTIC TROUBLE CODE PROCEDURES
(2)
Check the diagnostic trouble code (DTC).
Q:Is DTC P0446 set?
YES:
Retry the troubleshooting.
NO:
The inspection is complete.

CIRCUIT OPERATION
⦆
The ECM (terminal No. 114) supplies a 5-volt
reference signal to the fuel tank differential pressure
sensor (terminal No. 3). The fuel tank differential
pressure sensor (terminal No. 2) is grounded
through the ECM (terminal No. 113).
⦆
The fuel tank differential pressure sensor (terminal
No. 1) returns a voltage signal to the ECM (terminal
No. 112) that is proportional to the pressure in the
fuel tank.
TECHNICAL DESCRIPTION
⦆
The ECM monitors the fuel tank differential
pressure sensor output voltage.
⦆
The ECM determines whether the fuel tank
differential pressure sensor signal voltage is within
normal operating parameters.
DESCRIPTIONS OF MONITOR METHODS
⦆
Compare purge solenoid status with fuel tank
differential pressure sensor output voltage.
MONITOR EXECUTION
⦆
Continuous.
