My 2002 hyundai xg350L engine stops while driving, it can be restarted in about a minute.

The dealer said it was caused by a bad purge valve. They replaced it but the engine stopped again several days latter. The dealer said that it was a bad purge valve and replaced it again. Since then the engin some times stumbels but does not stop. HELP! II am afraid it is going to happen again.

I don;t think a purge valve can cause this time of problem .the purge valve controls the fuel vapor it the fuel tank and allows the engine to burn this vapor. Try driving the car with the gas cap lose and see what happens. These cars had problems with the fuel evap canisters breaking up.

Trying to get 2008 Jaguar VDP inspected after service done. I've driven 200+ miles and computer still reads not ready. What's next step?

You must complete a OBD2 drive cycle, unless you do the kind of driving that satisfies the computer testing you can drive for a year. Go here for the test and how you need to drive to complete the drive cycle.

1 Ensure that fuel filler cap is fully closed (minimum three clicks).

2 Fuel level > 30% and < 85%.

3 Using WDS scanner perform ECM DTC Clear (even if no DTCs are flagged).

4 Drive vehicle for a minimum of 2 minutes, and until engine is at normal operating temperature.

5 Using WDS, ensure that the EVAP Canister Purge Valve is operating by observing "PURGE VAPOR MANAGEMENT VALVE - DUTY CYCLE". If the valve is not

active, ECM adaptions have not been learned. Conduct a "green ECM" Drive Cycle as described in Technical Service Bulletin.

6 Drive vehicle to the road where the EVAP System Drive Cycle will be conducted. Stop vehicle and switch OFF the ignition. Leave ignition OFF for 30 seconds,

then restart the engine.

7 Accelerate briskly to 80 km/h (50 mph) ensuring that the engine speed reaches a minimum of 3500 rpm for a minimum of 5 seconds.


FUEL TANK PRESSURE - VAPOR RECOVERY SYSTEM". Avoiding high engine loads, drive the vehicle steadily between 65 km/h (40 mph) and 100 km/h (60

mph). Avoid driving conditions that will produce excessive fuel movement. WDS should give an indication that the test is active (it may take up to 30 minutes

before the test will initialize). When the test has initialized (EVAP Canister Close Valve CLOSED), it will take approximately 90 seconds for the test to complete.

9 (0.020 inch EVAP Test) Continue driving vehicle as explained in Step 8 for an additional 10 minutes.

10 Gently coast the vehicle to a stop. Allow the engine to idle for 2 minutes and view WDS "PURGE VAPOR MANAGEMENT VALVE - DUTY CYCLE", "CANISTER


active. When the test has initialized (EVAP Canister Close Valve CLOSED), it will take approximately 90 seconds for the test to complete.

11 If the 0.020 inch EVAP Test is not activated, the purge system vapor concentration may be too great. To reduce the vapor concentration proceed as follows:

12 Drive the vehicle for an additional 30 minutes avoiding driving conditions that will produce excessive fuel movement. Repeat Step 10. If the 0.020 inch EVAP

Test is still not activated, repeat the Drive Cycle from Step 6.
13 Using WDS, check for and clear flagged DTCs

Po441 2002 Hyundai, engine hard starting after fill up

Most likely is a bad EVAP purge valve. But check below list.
This indicates that a part of the EVAP control system is no longer functioning correctly. The EVAP system consists of many parts, including (but not limited to) the gas cap, fuel lines, carbon canister, purge valve, and other hoses. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle'sicon1.png fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.

EVAP emission canister purge is controlled by a valve which allows engine vacuum to pull stored fuel vapors from fuel tank into the engine to be burned, rather than be vented to atmosphere. A vacuum switch is used to detect when flow exists. If the PCM commands purge and sees that the switch is closed (indicating no detected purge flow) P0441 is set.
FB.init("dd7d9e9681341cde77587bc6a2029f6f"); on Facebook Symptoms

Likely, no symptoms will be discernible to the driver, other than the illuminated Check Engine Light.

A code P0441 could mean one or more of the following has happened:

  • Bad vacuum switch
  • Broken or damaged EVAP line or canister
  • Open in PCM purge command circuit
  • Open or short in Voltage feed circuit to Purge Solenoid
  • Faulty purge solenoid
  • Restriction in EVAP solenoid, line or canister
  • Corrosion or resistance in purge connector
  • Bad PCM
Possible Solutions

With a P0441 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:

  • Replace Leak Detection Pump / LDP
  • Repair damaged EVAP lines or canister
  • Repair open or short in voltage feed circuit to Purge Solenoid
  • Repair open in PCM purge command circuit
  • Replace purge Solenoid
  • Replace vacuum switch
  • Repair restriction in Evap line or canister or solenoid
  • Repair resistance in purge connector
  • Replace PCM

Trouble code P0441 indicates EVAP emiddion control system incorrect purge flow.
Possible faulty purge valve or circuit.
Possible causes: purge line plugged, vacuum hose failure, EVAP purge solenoid failure and/or emission canister clogged.

The coolant sensor is a 2 wire sensor located in the thermostat housing.

The car will run for 5 miles or idle for 20 minutes and then the engine just dies. It cannot be restarted until it cools down, or for about an hour or so. No check engine light comes on, and it runs...

Classic clogged fuel filter.
Restriction prevents full fuel flow but it will run until the restriction increases to the point there is not enough fuel.
But then when you stop, the pressure is off and some dirt can drop off, allowing it to restart again eventually.

However, it could also be a plugged purge valve. Using gas creates a vacuum, and the purge valve is supposed to maintain a slight vacuum, but let air in after a certain point. If it is not functioning, vacuum builds up until it won't run. Open the cap and listen for a whoosh. If so, then bad purge valve. Just open the vent line after the charcoal canister, to open air, and plug the line to the intake.

First of all, Hyundai did not produce the XG350 until 2002. You wrote 2001 Hyundai XG350L. The engine in the 2001 is 3.0 (XG300). Cant help you.

Let our Experts solve your "I have a 2002 Hyundai Elantra with fault code P0441 Not sure what this code means or how to fix the Problem.

P0441 is evap system insufficient purge. It means that the computer thinks the purge control valve isn;t operating properly. The fuel tank pressure sensor can send faulty info causing code to set but most of the time it is just the purge valve that needs replaced
