DTC DETECTION LOGIC
NOTE: If DTC P0441 is displayed with other DTC such as P2122, P2123, P2127, P2128 or P2138, first perform trouble diagnosis for other DTC.
In this evaporative emission (EVAP) control system, purge flow occurs during non-closed throttle conditions.
Purge volume is related to air intake volume. Under normal purge conditions (non-closed throttle), the EVAP canister purge volume control solenoid valve is open to admit purge flow. Purge flow exposes the EVAP control system pressure sensor to intake manifold vacuum.
Under normal conditions (non-closed throttle), sensor output voltage indicates if pressure drop and purge flow are adequate. If not, a malfunction is determined.
DTC CONFIRMATION PROCEDURE
1.INSPECTION START
2.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following before conducting the next test.
TESTING CONDITION: Always perform test at a temperature of 5C (41F) or more.
3.PERFORM DTC CONFIRMATION PROCEDURE-I
With CONSULT
4.PERFORM DTC CONFIRMATION PROCEDURE-II
When the following conditions are met, "TESTING" will be displayed on the CONSULT screen. Maintain the conditions continuously until "TESTING" changes to "COMPLETED". (It will take at least 35 seconds.)
CAUTION: Always drive vehicle at a safe speed.
If "TESTING" does not change for a long time, retry from step 2.
5.PERFORM DTC CONFIRMATION PROCEDURE-III
Touch "SELF-DIAG RESULTS".
6.PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to EC-311, "Component Function Check".
NOTE: Use component function check to check the overall monitoring function of the EVAP control system purge flow monitoring. During this check, a 1st trip DTC might not be confirmed.
Component Function Check
1.PERFORM COMPONENT FUNCTION CHECK
Without CONSULT
Diagnosis Procedure
1.CHECK EVAP CANISTER
2.CHECK PURGE FLOW
With CONSULT
3.CHECK PURGE FLOW
Without CONSULT
Do not depress accelerator pedal even slightly.
Vacuum should not exist.
Vacuum should exist.
4.CHECK EVAP PURGE LINE
5.CHECK EVAP PURGE HOSE AND PURGE PORT
6.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE
With CONSULT
7.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE
8.CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR CONNECTOR
9.CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR FUNCTION
10.CHECK RUBBER TUBE FOR CLOGGING
11.CHECK DRAIN FILTER
12.CHECK EVAP CANISTER VENT CONTROL VALVE
13.CHECK EVAP PURGE LINE
Inspect EVAP purge line (pipe and rubber tube). Check for evidence of leakage.
14.CLEAN EVAP PURGE LINE
Clean EVAP purge line (pipe and rubber tube) using air blower.
15.CHECK INTERMITTENT INCIDENT
Component Inspection
DRAIN FILTER

Description
The steering angle sensor is connected to the ABS actuator and electric unit
(control unit) in addition to CAN
lines. CAN (Controller Area Network) is a serial communication line for real
time application. It is an on-vehicle
multiplex communication line with high data communica ...
Checking tire pressure
1. Remove the valve stem cap from the
tire.
2. Press the pressure gauge squarely
onto the valve stem. Do not press too
hard or force the valve stem sideways,
or air will escape. If the hissing
sound of air escaping from the tire is
heard while checking the pressure,
reposition the gaug ...
