Hello,

My 2007 Explorer (XLT, V6 4.0L, 4WD, 175k miles) has been experiencing a check engine light, intermittently, for the past few months. I took it to AutoZone to read the code and they gave me a printout for P0193. For awhile, the light would go off after I filled the tank with gas (usually the next day) and would come again as the level in the tank decreased (typically around 1/4 of a tank). Then about two months ago, the behavior seemed erratic and I could no longer predict when it would appear. During the past couple of weeks I only recall seeing the CEL once (briefly); it's mostly been off. Saturday night I was out driving and it came on again. About two hours later, my vehicle "conked out" on me. It started hesitating (it's been a very long time since I've run out of gas, but that's what it reminded me of). Fortunately, there was no traffic and I was able to get it off the road but didn't have enough momentum to get it into a defined parking space before it quit. I sat there for awhile pondering my options (not too many since it was the middle of the night and I don't have road service). After about 10 mins or so, I decided to see if I could get it started. It did start and I was able to drive it home (< 10 miles). It's been sitting in the driveway since because I'm afraid of getting stranded if I drive it again. BTW, I was low on gas when it died -- about 50 miles to E (was headed to the gas station when it happened, but took it home instead).

After everything I've read the past few days, I'm expecting that I need to replace at least the fuel filter, the fuel rail pressure sensor and the intake gaskets for the manifold. I am not a mechanic, don't have diagnostic tools, my funds are really limited right now and I'm pretty much on my own to figure this out.

Q1: For those who may have some knowledge about this particular issue, does the intermittent nature of the CEL give any clues to which part(s) might be malfunctioning?

Q2: I found a replacement FRPS made by Bosch on Amazon, significantly cheaper -- can anyone give me a thumbs up on this brand or should i stick to Motorcraft?

Q3: Any advice on the manifold gasket replacements (is one brand better than another)?

Q4: Do I really need the special tool to replace the fuel filter?

UPDATE (7/26): The questions above are no longer relevant. I'm in the process of "locating" the sensor. I have the air hose and throttle body off. Now I'm looking at the EGR valve. It looks like I will have to disconnect the it from the large pipe beneath it. Will I also need to remove the two smaller bolts that mount it to the manifold cover, or can I remove the cover & valve together? It looks like those little buggers are going to be challenging since they are facing the back of the engine compartment. This is rather slow-going for me, but there's no turning back now.

Thanks!
Sandy

 

checking or replacing the Fuel Pressure Sensor is first... look at the wiring and plug for damage.. Changing the filter can not hurt... I doubt the manifold gaskets have anything to do with this problem as you have no other codes for vacuum leaks.

 

steve(ill) thanks for the reply. No, the manifold gaskets are not directly related to the problem, but everything I read (or watched) about the repair said they should be replaced once the cover has been removed, so that's why I added them to the list.

 

 

 

Not sure, but it made my life a lot easier:

 

Hi I'm new on here and I'm wondering how I make a new post I can't find how to do that?
I also have a question about my 1994 ford E150 5.8L. It has a high idle problem I have replaced the idle air control valve thinking that was it. But now it seems to be a bit higher. I'm not sure where to go from here.

 

I would see if AutoZone has that tool to use. If not I would buy it will make your life so much better. Look at it this way your time is very valuable so think of the labor time you will save yourself.
