I own a 2003 F-150 4.2 engine 2 wheel drive extended cab. I need finding an easier way to get at the O2 sensor connector on bank #2. I am having a trouble code of P0171 and want to check the sensor to see if it is working...
View 6 RepliesI have an 1997 Mountaineer AWD with the 5.0. The vehicle has 235,000 miles on it and has run great all this time. Early in the month the Check Eng light came on, I check the code and got "P0141 O2 Sensor Heater circuit Bank 1 Sensor 2". I check and found out it is the O2 sensor behind the Cat that is bad.
I have never change any O2 sensor on this vehicle since I have got it brand New. I have changed the oil every 5000 miles and flushed out the trans every 50,000 miles. New plugs and wires at 100,000 miles. I take good care of my vehicle as best as I can.
My Questions are, should I go ahead and change all the O2 sensor's? Which brings me to ask. How many O2 sensors does this vehicle have and where? Could it be something else causing the check eng light to come on? How bad is it to change all the O2 sensors out?
I have a 2003 F150 SuperCrew with 180k. Has been a great truck. Last fall the check engine light came on, and I took it to Advance Auto and they said to replace the lower O2 sensor. Did that and light stays on. Ever since then, and getting worse, is when I crank truck, it idles very rough, and if it sits too long it will just "choke itself out" and quit. Recently this has happened while driving on road too. I have to shift the gearshift to N to crank it. I get power but no crank if I try it in P.

View 10 RepliesFord catalog does not list the TPS for a 1999 7.3 Super Duty as a separate replaceable part which leads to replacing the whole throttle pedal assembly. I found this to be incorrect. If you have a throttle pedal assembly with separate TPS (separate 3 wire connector) and IVS (Idle Validation Switch 2 wire connector) just the TPS can be replaced.
This is a pic of my 99 with new TPS installed : [URL] .....
Without removing the whole assembly you only need to remove the 2 T25 screws and the connector to replace.
Since this part is listed for more then 20 Ford trucks I figured it would work in my 99 7.3. I bought a brand new TPS from Pete (F250_) that he could not use. He has a 2002 with one 5 wire connector. It works perfectly in my 99. Not sure if it will work in a 2000 or 2001 but if the TPS and IVS each have their own connector it should. Make a visual inspection to be sure.
Part DY-967 or F4SZ-9B989-AA - Potentiometer
I was going to go with a Dorman TPS but like PartsGuyED likes to say "OEM Baby". The OEM TPS through Ed is actually cheaper then the Dorman.
Side-by-side pic of the old and new TPS. Only the center rotating part is different but it fits and works just fine. It also has a better fit so there is less slop and almost immediate response.

By the way, the original TPS was working fine so I have no idea what the symptoms of a bad TPS are. Since it was available I replaced it to have a spare and to see if this one would work. Both Pete and I thought it would and we were right.
Looking for the Ford (or even Dorman) part number for the Water-in-Fuel sensor that bolts to the outside of the fuel bowl?
Guzzle has it pictured here:
The water sensor tip on mine is badly corroded and eaten away.
What's a part number and who sells them that I can get it delivered next day?
I've tried everything I can think of and it still runs sluggish.
1. Had dealer change plugs
2. Changed Cop's
3. Cleaned MAF sensor
The 5.4L has slight miss and doesn't respond well at all when trying to pass or going uphills.
I'm looking for the location of the ECM in a 97' f150 5.4.. Also need to know difficulty on replacing it and is it what controls the windshield wipers and windows?
View 1 RepliesI have a 2003 Passat 1.8t(B5.5) and I need to change my engine coolant temperature sensor. I have search and found conflicting answers on the forums as far as it location and description. From what I can see it is located near the bottom right hand corner of the radiator(Driver Side). I have removed the sensor and I did see some antifreeze spill out. I examined the sensor and it is blue in color with a rounded top. I called my local auto zone and received a replacement part but it is green and looks a little different.
I understand that the blue one that I removed is no longer produced. My question is is this the right sensor and the right location? All the write ups I can find say that it is located in the back of the engine yet I cannot find one there. Also when I replaced the blue senor with the green one the fan on my car is spinning at high speed(the AC fan) and will not idle. I am wondering if the new sensor is faulty/ incorrect or if i simply replaced the wrong sensor.
Here is a link to the replacement part I used : [URL] .....
I have a 2000 ford f 150 4x4. I just had to replace the engine in it because something got in my engine and beat it up and bent a valve. I replace the engine with one out of a 99 f 150. By the way it's a 5.4 triton. The engine I installed was suppose to have around 77,000 miles on it. I noticed when I got it that the dpfe sensor was melted off of it and so was the hose on one side. I never had that problem with the original engine. I took the dpfe sensor off the destroyed engine and put it on the used one I installed.
Low and behold in less that one day it melted off that one. I have read on here about cats being clogged and or the egr tube. I had no problem with my original engine so it's hard for me to believe the cats or clogged. I did happen to find a metal dpfe sensor off another truck and have installed. I am getting a rough idle now and not sure whats going on. I tried cleaning the egr tube the best I could without taking it off. Also the egr ports on the throttle body are cleaned and open and the egr valve itself is a new one.
I just recently pulled the P1401 code on my truck and need to get the sensor fixed before my next emissions test. I called the dealer and they told for the new sensor.

View 7 RepliesI had to swap in a new battery the other day, and I noticed that the positive terminal connector is broken. I don't really want to pay >$100 for a new cable right now, so any success story about splicing in just a new terminal ring or using one of the generic battery cables?
View 4 RepliesSo the story goes like this, my teacher was trying to scrap a truck that he had sitting on his farm so i got it. I've been using it for a DD for the past year and a half and not I'm starting to do rust repair starting with rocker panels. But, what i was really wondering is how involved would it be to replace the radiator core support? Main reason being last time i was under the hood replacing the pass side valve cover gasket i hit it and knocked a hole right through it so yeah I'm thinking is about time to replace it.

View 1 RepliesI have a 1999 Ford E150 4.2l. My cylinder head temp sensor was dangling but still connected to the sensor... the connector was loosed from the filament but was still connected by exposed metal pins.
I figured I would replace it like i did to my ECT by the Water Pump. So I pulled the connector out and it started to leak...a little. and when I put the socket on it I instantly broke the sensor flush with the Cylinder Head.
I researched on here and found many people believe the CHT gives info to the Dashboard Gauge and the ECT is used by the ECU. I thought that was correct because I had ECT readings from my scantool...and my Dash Gauge never worked. When I found the dangling CHT I figured it was never working.
So I JB welded CHT hole. figuring i would fix it properly later. I replaced the ECT and expected everything to go back to normal.. No gauge reading on dash and a scan reading with no codes.
I want to replace the CHT sensor properly. Do I HAVE to remove the manifolds. Or do you think its safe to drain the coolant and drill it out. Its easy access. Im worried about all the tiny pieces getting into narrow passage ways.
I am almost 100% going to drill out. Manifold sounds like hell and its getting cold. What sensor controls what? Can I drill it out safely?
Replacing lower control arms? I've read a couple places that you don't need a spring compressor. Anything else to look out for? 2000 F150 4.6L 2WD 288,000 miles....
