Question about 2001 Ford Windstar

1 Answer

Check engine light won't go off to pass inspection

We originally got the code 1409 which indicated a problem with the EGR valve system. We cleaned the component surrounding the valve (sensors etc), at first the light would go off then after a few miles would come back on. the we replaced everything, but the valve itself, same result. Then we cleaned the valve, drove the van for 60 miles, tried to get the van inspected again and it said that it was not ready, something about not enough drive cycle or something! Once we turned the van off, and back on, the light came on again! Today we replaced the valve. The light was off then came back on! the mechanics are stumped and so are we. Any one with a clue?

No Biggy.. Get them to install a DPFE sensor,, ( its the one that regulates the EGR valve ) Most ppl mistake a 1409 Code as Being EGR and it is kinda.. but when the valve maint fails.. its almost always the DPFE sensor.. Try that and lemmie know

PO402--EGR Flow Excessive Detected

There are other components besides the
egr valve in that sytem,so you got things to
diagnose there you skipped over

PO443---Evap Control System Canister Purge

Valve Circuit Malfunction


PO1409--EGR Vacuum Regulator Solenoid
Circuit Malfuntion


PO420 & PO430--Catalyst System Efficiency
Below Threshold---Basically worn out exhaust
converters you will need to replace


Advice--take to a repair shop & go thru the entire
car & resolve ALL Issues

2005 magnum p0406 egr valve sensor code error


P0406 indicates high voltage on the EGR sensor circuit. this is recommended for every 30,000 miles be inspected. although EGR system do not requires periodic inspection. instead, check only if engine trouble's develop. most EGR's requires replacing EGR valve, cleaning passages and installing new vacuum hose. misrouted vacuum hose causes engine poor operation. so. not just to unplug it.

I have a 2001 suzuki xl7, I replaced egr unit and installed new pvc valve. Still shows error code P0400. Why won't it pass deq?


You may have a EGR valve plugged exhaust gas passage, so when it is opened the systems computer doesn't see any change in the O2 signal voltage. To check this manually pull open the EGR valve, the engine should run very rough and will stall out most times, if you open the valve up and see no change in the engine idle the passages are plugged with carbon and must be cleaned. As long as you have this EGR problem the car will not pass smog.

Wont pass smog , check engine light is on . It is setting off code 1406


CODE P1406 - EGR VALVE PINTLE POSITION CIRCUIT MALFUNCTION CONDITIONS. POSSIBLE CAUSES EGR SOLENOID VALVE IS BINDING OR STICKING. EGR SOLENOID CONTROL CIRCUIT IS OPEN SHORTED TO GROUND OR TO B+. EGR SOLENOID POWER CIRCUIT IS OPEN CHECK THE ECS 10AMP FUSE.EGR SOLENOID FAILED. PCM HAS FAILED.

Code 1404 on 01 malibu


The Powertrain Control Module (PCM) monitors the Exhaust Gas Recirculation (EGR) valve pintle position input to ensure that the valve responds properly to commands from the PCM. When the ignition switch is turned ON, the PCM learns the EGR learned minimum position. The PCM compares the EGR learned minimum position to the EGR position sensor when the EGR valve is commanded closed. If the EGR position sensor indicates that the EGR valve is still open when the PCM is commanding the EGR valve closed, this DTC will set.

A scan tool that is capable of commanding the EGR circuits on and off is required to verify EGR performance and sensor feedback voltages at the PCM. However, this code is USUALLY caused by carbon getting stuck in the EGR pintle and holding it open. A good cleaning is usually all that is required to fix this.

You will need an EGR gasket. Remove the EGR valve and inspect the ports for heavy carbon deposits. These deposits can usually be cleaned out using screwdrivers and a piece of mechanics wire to break the carbon loose and some carb and choke cleaner to finish the clean-up. A wire brush and some carb cleaner usually works for the EGR valve itself. Once the ports and the valve are clean, re-install the valve using the new gasket. Clear the codes and drive the vehicle to see if the problem is fixed. Please note that the EGR monitor runs at speeds over 50 Mph. during deceleration, so you need to get the vehicle on the highway for a valid test of the EGR system.

If the Check Engine light does not come on during the road test, Connect a code reader and check the OBD readiness monitors. If the EGR monitor says "complete" and there are no codes in the computer, then you have done a successful repair.

FAILED EMISSIONS TEST P0401&P0420 CHECK ENGINE LIGHT RESETED MANY TIMES WHEN CUT OFF ENGINE LIGHT COMES BACK ON AFTER 5-6 MILES. I HAVE REPLACED EGR VALVE .STILL WA\ONT PASS INSPECTION. WHATS NEXT?


P0401 indicates that the Exhaust Gas Recirculation Flow Insufficient Detected. This can be because EGR is faulty . As you have replaced this then the problem must be with the vacuum line . EGR valve vacuum line which can be broken or blocked. The vacumn ine must bbe checked for leaks or any blocks using an vacumn pump connected the line.

P0420 indicates that the down stream oxygen sensor reading is not steady and it is connected with the code P0401.

Can't pass state inspection, changed EGR valve already, next?


I suggest quit hunting for maybes and rent an OBD code reader which ends up being free when you return it to the auto parts store. Connect it and find out what is causing the CEL condition. Normal issues are the O2 sensor, or sensors in the system.

You need a charcoal canister and vent control valve.

You also need the EGR solenoid valve (I think it the brown one).

Valve is located in the valley of the V, towards the transmission side of engine.

Do these 1st and reset light. You may have other issues but you have to start here.
