13Ac-429
DTC SET CONDITIONS
Check Conditions
• Engine is being cranked.
• Battery positive voltage is at between 10 and 16
volts.
Judgment Criteria
• The evaporative emission ventilation solenoid
coil surge voltage (battery positive voltage + 2
volts) is not detected for 0.2 second.
• The PCM monitors for this condition once during
the drive cycle.
Check Conditions
• Battery positive voltage is at between 10 and 16
volts.
• ON duty cycle of the evaporative emission purge
solenoid is 0 percent.
• Evaporative emission ventilation solenoid is ON.
• More than 1 second has elapsed after the above
mentioned conditions have been met.
Judgment Criteria
• The evaporative emission ventilation solenoid
coil surge voltage (battery positive voltage + 2
volts) is not detected for 1 second. When the
evaporative emission ventilation solenoid is
turned OFF.
.
TROUBLESHOOTING HINTS (The most likely
causes for this code to be set are: )
• Evaporative emission ventilation solenoid failed.
• Open or shorted evaporative emission ventilation
solenoid circuit, or loose connector.
• PCM failed.
DIAGNOSIS
Required Special Tool:
• MB991502: Scan Tool (MUT-II)
STEP 1. Using scan tool MB991502, check actuator test
item 29: Evaporative Emission Ventilation Solenoid.
CAUTION
To prevent damage to scan tool MB991502, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991502.
(1) Connect scan tool MB991502 to the data link connector.
(2) Turn the ignition switch to the "ON" position.
(3) Set scan tool MB991502 to the actuator test mode for item
29, Evaporative emission ventilation solenoid.
• An operation sound should be heard and vibration
should be felt when the evaporative emission ventilation
solenoid is operated.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the solenoid operating properly?
YES : It can be assumed that this malfunction is intermittent.
Refer to GROUP 00, How to Use Troubleshooting/
Inspection Service Points
NO : Go to Step 2.

STEP 2. Check connector G-27 at the evaporative emission
ventilation solenoid for damage.
Q: Is the connector in good condition?
YES : Go to Step 3.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
. Then go to Step 12.
STEP 3. Check the evaporative emission ventilation
solenoid.
(1) Disconnect the evaporative emission ventilation solenoid
connector G-27.
(2) Measure the resistance between evaporative emission
ventilation solenoid side connector terminal No. 1 and No.
2.
Standard value: 17
− 21 ohms [at 20°C (68°F)]
Q: Is the resistance between 17 and 21 ohms [at 20
°C
(68
°F)]?
YES : Go to Step 4.
NO : Replace the over vent valve module. Then go to Step
12.

STEP 4. Measure the power supply voltage at evaporative
emission ventilation solenoid harness side connector G-
27.
(1) Disconnect the connector G-27 and measure at the harness
side.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal No. 2 and ground.
• Voltage should be battery positive voltage.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is battery positive voltage (approximately 12 volts)
present?
YES : Go to Step 6.
NO : Go to Step 5.
STEP 5. Check connector B-22X at MFI relay for damage.
Q: Is the connector in good condition?
YES : Check connectors D-116, E-111, D-112 and F-10 at
intermediate connector for damage, and repair or
replace as required. Refer to GROUP 00E, Harness
Connector Inspection
. If intermediate
connectors are in good condition, repair harness wire
between MFI relay connector B-22X (terminal No. 1)
and evaporative emission ventilation solenoid
connector G-27 (terminal No. 2) because of open
circuit or short circuit to ground. Then go to Step 12.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
. Then go to Step 12.

STEP 6. Measure the power supply voltage at PCM
connector D-132 by backprobing.
(1) Do not disconnect the connector D-132.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal No. 11 and ground
by backprobing.
• Voltage should be battery positive voltage.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is battery positive voltage (approximately 12 volts)
present?
YES : Go to Step 9.
NO : Go to Step 7.
STEP 7. Check connector D-132 at PCM for damage.
Q: Is the connector in good condition?
YES : Go to Step 8.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
. Then go to Step 12.
