2000 FORD WINDSTAR P0174 CODE Sign In

I had a P0174 FAULT CODE ON MY 2000 FORD WINDSTAR 3.8. I DID THE UPPER PLENIM GASKETS AND THE PCV . THE CHECK ENGINE LIGHT WAS OFF FOR A MILE AND CAME BACK ON. I THOUGHT IT MAY HAVE WENT OFF DUE TO THE BATTERY NEG. CABLE OFF WHILE I DID THE REPAIR. I DON'T WANNA DO A BUNCH OF REPLCEMENTS. IN THE RESEARCH I'VE DONE I HAVE SEEN SOME POSTINGS ABOUT NEWER UPDATES TO COMP. I'M KINDA LOST. I LIKE TO DO MY OWN WORK IF I CAN. I'M NO MECHANIC BUT PRETTY MECHANICAL.HOPING TO GET SOME INFO ABOUT WHAT TO DO OR CHECK NEXT

If you already replaced the isolator bolts, then you have probably eliminated the intake as the problem. The fact that it's only setting the code on one side would have probably pointed away from that anyway. Look for something on bank2 only like an exhaust manifold leak, bad o/2 or injector problem.

Yes, I meant the bolts and bushings for the middle section and the gasket below that.

I did not replace the insulator bolts. the code just said bank 2 nothing else about 1 or 2 meaning before or after the cat. If it is a exhaust manifold wouldn't I hear it? Also what about the updates that I have seen postings about. I have seen other postings that they had to have some newer software installed to correct the code fault. Any stock in this and how do I know if it has been done ?

It has nothing to do with after the cat. PO174 is bank 2. You normally also get PO171 for bank 1 also.

The isolator bolts and the middle gasket are the main issues that have to be corrected.

Here is the TSB on it



Article No.
03-16-1
08/18/03 ^ DRIVEABILITY - DIAGNOSTIC TROUBLE CODES(DTCS) P0171/P0174 STORED IN MEMORY -
VEHICLES EQUIPPED WITH 3.8L ENGINE ^ MALFUNCTION INDICATOR LAMP (MIL) - MILILLUMINATED WITH DIAGNOSTIC TROUBLE
CODES (DTCS) P0171/P0174 STORED IN
MEMORY - VEHICLES EQUIPPED WITH 3.8L
ENGINE FORD:
1999-2003 WINDSTAR
This TSB supersedes articles 03-4-7 and 00-21-8. ISSUE
Some vehicles may exhibit a check engine light on and lean Diagnostic Trouble Codes (DTC's) P0171/P0174 (system too lean bank 1 or 2) stored in memory. ACTION
Do not replace PCM (Powertrain Control Module), MAF (Mass Air Flow), or HEGOs (Heated Oxygen Sensors), as these parts are not the root cause of the lean codes conditions described. Refer to following Service Procedure for details.
SERVICE PROCEDURE
These conditions may be caused by a loose fitting on the fuel pressure regulator vacuum line on the intake manifold end and/or leaking isolator bolts/port gaskets in the lower to upper intake manifold mounting area. This condition is sometimes intermittent and may not be apparent on a warmed-up engine.
If the vacuum line from the intake manifold to the fuel pressure regulator is loose at the manifold (due to oil contamination), replace the vacuum line (9E498) and install a new design LH service valve cover (6582). Another vacuum leak source is the gasket (9H486) between the upper and lower intake manifold assemblies caused by a loss of tension at the isolator bolt assemblies (9S479) due to contamination of the rubber grommets from excessive oil pullover. 1. Perform self test, if codes P0171, P0174 are the only codes stored in the PCM then continue with this article. For any other codes, follow the normal diagnostic procedures found in the PC/ED Manual.


2. (ALL 1999-2003). Reprogram the PCM (Powertrain Control Module) with the latest calibration, WDS B26.2 release or later. Do not replace the PCM. Reset the keep alive memory. 3. (1999-2001 ONLY). Inspect the vacuum line from the intake manifold to the fuel pressure regulator for looseness, leaks and/or oil contamination and replace Vacuum Line (XF2Z-9E498-DD) if required. 4. (1999-2000 ONLY). Inspect the LH Valve Cover, it should be a (3F2Z-6582-BA) Install a new LH Valve Cover if required, refer to Workshop Manual Section 303-01 valve cover-LH. (Refer to the following NOTE for description of the old style valve cover).


NOTE USING A SHOP LIGHT OR FLASHLIGHT, CHECK THE LH VALVE COVER TO SEE IF IT HAS ALREADY BEEN UPDATED TO THE LATEST LEVEL. REMOVE THE PCV VALVE AND RUBBER GROMMET FROM THE VALVE COVER AND LOOK THROUGH THE HOLE AT THE INTERNAL SHEET METAL BAFFLE. THE OLD STYLE VALVE COVER BAFFLE HAS A 3/16" DIAMETER HOLE IN THE 5:00 O'CLOCK POSITION AS YOU LOOK THROUGH THE PCV HOLE (FIGURE 1). VALVE COVERS FITTING THIS DESCRIPTION MUST BE REPLACED. 5. (ALL 1999-2003). Remove the upper intake and replace only port gaskets (9H486) and isolator bolt assemblies (9S479). The new isolator bolt assemblies use a rubber material that is green in color, do not use the old isolator bolt assemblies with the black rubber material (XF2Z-AA). Do not replace any other intake parts (black plastic or aluminum) or the lower intake gaskets, (9439 and 9A424/425) or the upper intake clamshell gasket (9461). Refer to Workshop Manual Section 303-01, intake manifold-Upper. 6. (ALL 1999-2003). While the upper intake manifold is removed, check the Exhaust Gas Recirculation (EGR) orifices that are pressed into each primary port of the lower intake manifold. If any of the orifices are plugged with soot, clean and unplug them with a pick and solvent. CAUTION DO NOT USE SMOKE DETECTION, PROPANE GAS, OR CARB CLEANER TO TEST FOR VACUUM LEAKS. (CARB OR BRAKE CLEANER MAY CAUSE INTAKE MANIFOLD RUNNER CONTROL (IMRC) BEARING FAILURE). SOME LEAKAGE FROM THE IDLE AIR CONTROL (IAC) OR EGR VALVE AND IMRC SEALS IS NORMAL. DO NOT REPLACE THESE PARTS, ESPECIALLY THE LOWER ALUMINUM INTAKE MANIFOLD. NOTE THIS CONDITION COULD ALSO BE DUE TO WARM AMBIENT TEMPERATURES AND THE USE OF WINTER GRADE FUELS WHICH HAVE VERY HIGH VOLATILITY AND MAY BOIL IN THE FUEL LINES (VAPOR LOCK) DURING A SHORT HOT SOAK. OXYGENATED FUELS WILL AGGRAVATE THIS CONDITION. IF NON-OXYGENATED FUEL IS NOT AVAILABLE, USE MID/HIGH OCTANE FUELS WHICH HAVE LOWER VOLATILITY AND MAY HELP ALLEVIATE THE CONDITION.



Obtain an Authorized Modifications Decal (FPS 8262 - obtainable through DOES II, 25/pkg) and list the date, dealer number, and summary of modifications performed. Select a prominent place adjacent to the Vehicle Emission Control Information Decal suitable for installing the Authorized Modifications Decal. Clean the area, install the decal, and cover it with a clear plastic decal shield.
