Question about 2001 Hyundai Sonata

1 Answer

Thanks, there is no EGR. I called up the dealer and the component is called Purge Valve in Sonata V6. I even tested Purge Valve by removeing it and that valve is NOT struck open. What should I do now? Replace the catalytic converter or something else. Please suggest. Thanks again

It shows code P0401. Already replaced the EGR valve and catalytic converter plus sensors. What now.


You didn't say if you have any symptoms so I will assume you don't. After you made the repairs, you have to have the code removed. Any major auto parts store will do it for free. If the code don't come back, its fixed.

2003 hyundai sonata 2.4 dtc po401 have changed egr egr solenoid and plastic vaccum valve cleaned intake ports replaced o2 sensor checked wiring all the way back to computer cleaned all engine grounds...


problem is typically the sensor or the device that is being monitored by the sensor. The the EGR return pipe is not properly engineered, a cold pipe with cause the inside to gum up with carbon deposit. This pipe is used to pick up exhaust gas to dilute the air before the combustion. If this "connection" is clogged, you will have a rough time at higher speeds. Pipe is easy enough to remote and take a look inside. If the gum up is too thick, I won't spend the time to chissle this out and just buy a replacement.

Where is the vapor canister purge valve located on a 2005 Hyundai Sonata 2.7L V6?


Usually the vapor canister's are located on most vehicles on the driver's side fender. You can otherwise follow the vapor lines from the gas tank to it and the valve which usually gets stuck in place by a residual vapor/moisture build up can sometimes be freed up by using a can of carb cleaner and a small screwdriver. Depress the valve which is plunger and spring activated more or less and spray the carb cleaner into it. Do this several times (you can do this for egr or other faulty valves that are stuck SOMETIMES) then start your vehicle and see if trouble code persists if it does then replace the valve and you're only out about 4 dollars for carb cleaner

I'm receiving an Error code po441, I took it to the dealer who replaced the EGR valve and reset the engine light and cleared codes a week ago, now my engine light just came back on with same code


Some dealer you got there

PO441-EVAP System --Incorrect Purge Flow

They may have found an EGR Valve issue,
but they certainly blew off the EVAP Code

I would guess you have a bad EVAP Canister
Purge Valve or some other purge control

Purge Control Valve Problem

The "Purge Control Solenoid Valve" is the "Purge Control Valve".

Rough idle is a typical symptom of something amiss with the purge control portion of the evaporative emissions system. It could be the valve itself is not operating correctly, the evap canister (vapor canister) may be leaking, or full of raw gas instead of vapor, or maybe even the purge control valve is getting a faulty signal from the ECU.

The soleniod is checked by applying a voltage to it and checking to see if it closes, or opens (I'm not sure if its un-energized state is normally open, or normally closed). If the valve is bad it is a no-brainer to replace.

The vapor canister can be removed and checked to see if it is full of raw gas (not supposed to be), but checking it for leaks is a bit involved, and probably requires equipmet not normally owned by a home mechanic. Vapor canister failure on cars with a lot of miles is common. Replacement is the fix.

Of course if the ECU is not sending a purge signal to the valve correctly, figuring out why may proove difficult, and possibilities could even include a faulty ECU. I expect this is unlikely though.

It's a $20 part. I first would change pcv valve because it can give same error if it's plugged up. You can always remove it and shake it. It should rattle around real easy. If not, it should be repalced

99 5.4 Expedition issues


P0401 - EGR Flow Insufficient Detected The EGR system is monitored during steady state driving conditions while the EGR is commanded on. The test fails when the signal from the DPF EGR sensor indicates that EGR flow is less than the desired minimum.
  • Vacuum supply
  • EGR valve stuck closed
  • EGR valve leaks vacuum
  • EGR flow path restricted
  • EGRVR circuit shorted to PWR
  • VREF open to DPF EGR sensor
  • DPF EGR sensor downstream hose off or plugged
  • EGRVR circuit open to PCM
  • VPWR open to EGRVR solenoid
  • DPF EGR sensor hoses both off
  • DPF EGR sensor hoses reversed
  • Damaged EGR orifice tube
  • Damaged EGRVR solenoid
  • Damaged PCM

P1299 - Cylinder Head Over Temperature Protection Active Indicates an engine overheat condition was detected by the cylinder head temperature (CHT) sensor. An FMEM Strategy called Fail-safe Cooling was activated to cool the engine.
  • Engine cooling system concerns
  • Low engine coolant level
  • Base engine concerns

P0300 - Random Misfire The random misfire DTC indicates multiple cylinders are misfiring or the PCM cannot identify which cylinder is misfiring.
  • Camshaft position sensor (CMP)
  • Low fuel: less than 1/8 tank
  • Stuck open EGR valve

P0443 - EVAP Control System Canister Purge Valve Circuit Malfunction The PCM monitors the EVAP canister purge valve circuit for an electrical failure. The test fails when the signal moves outside the minimum or maximum allowable calibrated parameters for a specified purge duty cycle by PCM command.
  • VPWR circuit open
  • EVAP canister purge valve circuit shorted to GND
  • Damaged EVAP canister purge valve
  • EVAP canister purge valve circuit open
  • EVAP canister purge valve circuit shorted to VPWR
  • Damaged PCM

P1451 - EVAP Control System Canister Vent Solenoid Circuit Malfunction Monitors the canister vent (CV) solenoid circuit for an electrical failure. The test fails when the signal moves outside the minimum or maximum allowable calibrated parameters for a specified canister vent duty cycle by PCM command.
  • VPWR circuit open
  • CV solenoid circuit shorted to PWR GND or CHASSIS GND
  • Damaged CV solenoid
  • CV solenoid circuit open
  • CV solenoid circuit shorted to VPWR
  • Damaged PCM

P1309 - Misfire Monitor Disabled When the misfire monitor is disabled, usually due to the input signal generated by the camshaft position (CMP) sensor, by sensing the passage of teeth from the CMP wheel.
  • Camshaft position sensor
  • Powertrain control module
  • ECT, MAF, and CKP sensors

with the codes you have here I would look in the direction of the egr valve first because that will cause the bucking and stalling, and the misfires, but so will the canister vent solonoid. the misfire codes and the cylinder overtemp code could be from overheating or because if the misfires.

Check engine light on po441


P0441 = Evap. Emission Ctrl. System Incorrect Purge Flow. Listed Cause - valve stuck in open position.
INSPECTION (4 cylinder engine)
When disconnecting the vacuum hose, make an identification mark on it so that it can be reconnected to its original position.cc59427.jpg 1. Disconnect the vacuum hose (black with red stripe) from the solenoid valve. 2. Detach the harness connector. 3. Connect a vacuum pump to the nipple to which the red-striped vacuum hose was connected. 4. Apply vacuum and check when voltage is applied to the EVAP Canister Purge Solenoid Valve and when the voltage is discontinued.
31f3588.jpg Battery voltage Normal condition
When applied Vacuum is released
When discontinued Vacuum is maintained
