So I'm getting code p0500 the question I have is will the speed sensor on the tail on my transmission cause this code on my 99 f150 4x4 . the reason I ask is because this sensor has been broken off . I'm hopeful it only control's my speedometer and is not related to the code . I've tried to remove what is left however in fear if I get it loose it may fall into the transmission. I will be replacing the speed sensor on the pumpkin this weekend . but the transmission it's the upper one is broke off below the surface of the transmission this is a manual transmission....

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.

So I just replace my Cat. Converter with all new sensors in them. I just replaced my spark plugs. (I'm knocking out these check engine light problems) and I think I'm getting close to the root as to why these other parts went bad. Why my o2 sensor would be stuck on "lean" ....

1999 xlt with 5.4 lt p0171 only. it started with what felt like a misfire or hesitation and rough idle. Extremely rough at 40-45 mph. but with no misfire codes just p0171 so all 8 coils and plugs and sparks replaced twice in one month. and still same code tested fuel pump pressure 28 psi.... removed clogged cats, still same code... new pcv valve and elbow.... checked for air leaks around intake and intake manifold and nothing.... cleaned mass air flow sensor...I can unplug any coil on bank 1 and it wont make a difference. But if I unplug any bank 2 coils and engine makes a difference.

Dreaded insufficient EGR flow. I've read I should clean the EGR ports.
I can't really find where these are? I took the throttle body off.
What I should do with this thing? I also get a hesitation on initial take off.
1999 F150 4.2 V6 ... 160k miles on it. Runs good otherwise.

1999 F150 4.2L 125K miles.... My problems started about a month ago. I had a P1506 error. The engine was running fine but received the error code. I replaced the IAC and the air filter. Engine still running fine. A week later I received a code for the Intake Air Temp Sensor (don't remember the code). The engine still running great. I bought a new Air Temp Sensor and noticed the wires from the Air Temp Sensor were rubbing against the belt and had been severed. I made a mistake when replacing the air filter of not checking the wires (confession is good right).
The engine also constantly ran a fast idle 2000 to 2500 at this time. I repaired the wires. The engine light went off and idle now starts great and smooth but when heats up will will go to 2000-2500. I then decided to replace the Air Temp Sensor hoping to fix idle problem. Engine still idle fast when warm. However, when I come to a stop and put in neutral the engine will take a minute but go down to normal idle after sitting. Engine light stayed off for a week. Now engine light back on with original code P1506. Idle is still not working correctly.
I feel like I made it worse than it was originally and not sure what to try next.

I have a 1999 F-150 with the 4.2L engine. I recently did a motor swap as the original motor was bad. I bought this truck as a project truck and have enjoyed working on it.
When I did the engine swap back in May of this year, it took a while to work out all the little bugs and quirps. However, after a while of running the truck it threw a few codes. I replaced a lot of the emission components and no more codes for several months until last month the truck started throwing the infamous P0174 "too lean bank two"... I have replaced the pcv valve and all the hoses to include the little rubber boot under the front of the intake, all 4 O2 sensors, MAF sensor, EGR, DPFE, IAC valve, new wires and plugs to include coil pack, fuel pressure regulator, and all the vacuum lines that are under the hood.
The truck runs fine, has power, but about every couple weeks or so it throws this P0174 code. I know there are alot of threads on here about this problem and I have read many of them. It only throws the P0174 and not the P0171. I am wondering if there could be a problem specific to "bank 2" that I am over looking.

Here is my situation : I have a F150 1999 4x4 ext cab with 326 000 km. A little while ago I got a P0401 code so I decide to clean the TB first and at the same time change plugs and wires since they were overdue. The same code came back and a misfire. Ordered EGR valve, DPFE sensor and selenoid. Realize that I had ordered crappy plugs by mistake. I change all plugs. Had to wait for the EGR valve and others to arrive. I drove the truck for a while since I did not have the time to change the valve and others, during that time the misfire did not come back. Yesterday I change the EGR and others. Today I get a truck that runs really rough and got new codes , P0305 and P0174. I'm really confused now on what should be my next step, should I change the coils, can a P0305 cause a P0174. Should I change vacuum hose going to the EGR , selenoid and DPFE.

I have received the error code P1506 on my 1999 F150 which is I believe an idle air control overspeed error. It seems to run a little rough at idle but not too bad. At the advice of my Haynes repair manual and the advice of a friend I have already replaced the IAC valve and the PCV valve on the engine and cleared the code, only for it to come back again after 50K miles. I am not sure where to go next with the diagnosis/fix.

I have an intermittent security system issue. I sometimes get a dotted line in odometer and rapidly flashing theft light.
Crank no start. After a time, the theft light flashes a code of 1 then 4. Research gives me the result that PCM did not power up.
Have pulled gauges. Fixed known cold solder joint issue. Checked all connectors and reinstalled. Truck starts fine about 7/10 tries.
I have replaced battery terminals. Removed cleaned and replaced all firewall grounds. Checked harness connection blocks and PCM connector. Made sure all under hood fuses and relays working.
Currently sitting in a parking lot waiting for it to decide to start again. Only one chipped key. Where to look next? 1999 F150 xlt 6 cylinder.

99 F250LD 4x4 w/5.4 and 215k . I'm sure I'm not the only one with this problem. Just had quite a bit of rain in my area. I didn't drive the truck in it but 3 days after the rain stopped I did. Skipping badly ! It has done it before and will clear itself up after a heat cycle or two. This time it kicked a p0307 code. # 7 cylinder not fire correctly I believe. I got ready to replace the cop but decided to wait a day. In the mean time I pulled the connector and blue compressed air through it and the male connector.
The next morning I decided to drive it before replacing the coil. Absolutely no skipping at all. Drove at different speeds , up heels slow , high speeds, no skipping. Ran the truck for about 20 minutes or so. Is the connector getting moisture in it ? Can I fill the connector with dielectric grease? Is there another problem. I cleared the codes and am going to drive a couple of cycles to see if any come back. Like I said it has done this before but not bad enough to throw a code so I'm not sure if it's always number 7.

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 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...

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.
