TROUBLESHOOTING HINTS (The most likely
causes for this code to be set are:)

｠

Evaporative emission purge solenoid failed.

｠

Harness damage

｠

Connector damage

｠

ECM failed.

DIAGNOSIS

Required Special Tools:

｠

MB991958: Scan Tool (M.U.T.-III Sub Assembly)

｠

MB991824: V.C.I.

｠

MB991827: USB Cable

｠

MB991910: Main Harness A

STEP 1. Using scan tool MB991958, check actuator test item
10: Evaporative Emission Purge Solenoid.

Data link

connector

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before
connecting or disconnecting scan tool MB991958.

(1)

Connect scan tool MB991958 to the data link connector.

(2)

Turn the ignition switch to the "ON" position.

(3)

Set scan tool MB991958 to the actuator test mode for item
10, Evaporative emission purge solenoid.

｠

An operation sound should be heard and vibration should
be felt when the evaporative emission purge 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 - How to Cope
with Intermittent Malfunctions P.00-15.

NO:

Go to Step 2.

STEP 2. Check harness connector A-33X at the MFI relay
and harness connector B-07 at the evavorative emission
purge solenoid and harness connector B-10 at the ECM for
damage.

Q:Is the harness connector in good condition?

YES:

Go to Step 3.

DIAGNOSTIC TROUBLE CODE PROCEDURES

NO:

Repair it. Refer to GROUP 00E, Harness Connector

Inspection P.00E-2. Then go to Step 7.

STEP 3. Check the evaporative emission purge solenoid.

(1)

Disconnect the evaporative emission purge solenoid
connector B-05.

Evaporative emission
purge solenoide connector

(2)

Measure the resistance between evaporative emission purge
solenoid side connector terminal No. 1 and No. 2.

Standard value: 22 - 26 Ω [at 20°C (68°F)]

Q:Is the measured resistance between 22 and 26 ohms [at

20°C (68°F)]?

YES:

Go to Step 4.

NO:

Replace the evaporative emission purge solenoid.

Then go to Step 7.

STEP 4. Measure the power supply voltage at the
evaporative emission purge solenoid connector B-07.

(1)

Disconnect the evaporative emission purge solenoid
connector B-07 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 the measured voltage between 4.9 and 5.1 volts?

YES:

Go to Step 5.

NO:

Repair it. Then go to Step 7.

STEP 5. Check for open circuit and short circuit to ground
and harness damage between the evaporative emission
purge solenoid connector B-07 and the ECM connector
B-10.

(1)

Disconnect the evaporative emission purge solenoid
connector B-07 and the ECM connector B-10.
