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.

Ford F-150 - 1997-2003 :: DPFE Sensor Melted Off
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 had both manifold cats replaced and the egr valve which blew a hole thru the side of it and I replaced the hoses and the dpfe sensor due to the dealer said the 2 front cats were plugged this is what happened before cats were fixed the dpfe sensor blowing off and melting then the egr blew a hole in the side on my way to the garage and I also replace the fluid sensor for the master cylinder res because it looked broke and my brakes weren't working right either now that all this was fixed 3 days ago I drove it to the store this am 1/4 of a mile and the dpfe hose blew off again what is going on? ford says I should have the fuel pressure checked?
View 7 RepliesFord Ranger / B-Series :: 1998 - Code P1405 - DPFE Sensor Circuit Upstream Hose
I just bought a '98 Ranger 2.5l 2wd. After driving it for a week or so I got a P1405 Code. After a quick google search I got :
P1405 Ford - DPFE Sensor Circuit Upstream Hose
Possible Causes: - Faulty Differential Pressure Feedback Electronic (DPFE) sensor (EGR pressure sensor)
- Plugged or damaged EGR tube
- Differential Pressure Feedback Electronic (DPFE) sensor harness is open or shorted
- Differential Pressure Feedback Electronic (DPFE) sensor circuit poor electrical connection
Now, I have done my research between forums and youtube and have found this EGR system to be quite. I've gone ahead and replaced my DPEF. I took an air hose and blew out all the small lines coming into the DPEF. I still have the engine light. My next move is to get a volt meter and see if I'm getting power to the sensor.
My question is about this particular code and is it possible I need to look farther into this EGR system (EGR Valve, EGR Hose, etc.)
Ford - Explorer :: 2003 4.6 - Low Idle / Stalling - Code For DPFE Pops Up
2003 Limited with 4.6, 89K miles. Just started doing this last night. Checked codes, had the DPFE one pop up. Replaced that, no luck. Cleaned the IAC, MAF, throttle body, EGR, PCV, no luck. Used carb cleaner and sprayed around intake & vacuum hoses, no luck there. Checked vacuum, steady 20in even when it lopes. Battery unhooked for 15 minutes. It hovers around 300-400rpm's, sometimes will stall but drives fine. Tested the IAC and it is functioning normally. Nothing above has worked.

View 1 RepliesFord F-150 - 1997-2003 :: Sensor Broke In Cylinder Head?
I 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?
Ford F-150 - 1997-2003 :: 2001 - Location Of Automatic Lights Sensor?
I've got a 2001 f150 XLT and I've checked the Haynes manual and searched Google but I'm having no luck.
I'm trying to locate the sensor for the Automatic Head Lights.
I had a small "spill" on the dash at night and immediately the lights started to blink and click. It fixed itself but sometimes it will do a weird little "click, click noise" change thing. I would like to clean the sensor or ensure it's not partially blocked.
Ford F-150 - 1997-2003 :: 2000 - P0136 (Bank1 Sensor 2) Code
I recently replaced both the downstream O2 Sensors in my 2000 4.2L F150 because I was getting a P0136 (Bank1 Sensor 2) code that I couldn't get rid of by cleaning the connector or fixing wires. 110K miles. Calif truck. No other codes and has always passed smog test easily.
When I pulled the sensors, the Driver's side unit was extremely sooty, as compared to the passenger side (bank 1). The code failure was on bank 1.
Is this normal or is there some rich condition on the driver's side bank that I need to check into ? Originals were Bosch, replaced w/ Motorcraft, if that makes any diff. One on left is driver's side unit.
Ford F-150 - 1997-2003 :: 2001 - O/D Light On Even Replaced Sensor And Hoses?
i just got an F150 supercrew 5.4L 4x4. has approximately 180k miles but motor and tranny run clean and smooth. issue i am having is the OD light flashes but no other service light is on. i had code read and said it was a Differential Feedback Pressure Sensor (DFPS). Replaced the sensor and hoses but still the light is flashing. i have not changed EGR as of yet due to money but was wondering if i could maybe get pointed in the right direction. the Tranny does not seem to be operating improperly except at low speeds it tends to shift between OD and 3rd on occasion.

View 3 RepliesFord F-150 - 1997-2003 :: 2002 V8 - Rough Idle Only When Cold - O2 Sensor?
So I recently acquired a 2002 F-150 4x4 super crew with the 5.4 V-8. It idles rough (surging from 400 - 700 rpm) when cold, and sometimes dies, but more often then not it stays running. It runs and drives fine when the accelerator is pressed and when going down the road. When it gets up to operating temperature, and has been there for a while, it seems to idle fine 95% of the time. The codes I have are P0136 (bad circuit to O2 sensor), P1151 (HO2S detects lean mixture or something like that), and the infamous P0171 and P0174, which is lean exhaust/mixture on both banks. Now I have read extensively on the internet about these symptoms and have done the following:
Sprayed every vacuum hose with carb cleaner, and even around the intake manifold and injectors.
Considered the IAC (its new, the guy I bought it from replaced it a couple months ago) Torque app for android phone says vacuum is good. Cleaned the MAF and air temp. sensor with electrical cleaner Checked all of the vacuum hoses on the engine by pulling them off
Put grease around the fitting where the PVC valve attaches to the valve cover. Seemed to make it idle a lot better after messing with it, but I don't know if it was a result of the engine being fully warmed up, or my messing with the PVC.
What to try next? I'm close to just dissecting the top part of this engine and seeing what the intake manifold gasket looks like..or could it really be an 02 sensor?
