Ford F-150 - 1997-2003 :: 1999 5.4L - Code P1506 - Idle Air Control Over Speed Error
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.

About 3 days ago I noticed my engine RPM was around 250 higher than usual. Usually my truck idles around 550-600 rpm (I know this is low). Anyway, yesterday it threw the P1506 "IAC over Speed Error" Code. It is idling very rough, shifting weird, but does crank up fine.
My truck is now at 93,000 miles and I just cleaned the IAC at 87,000 miles due to the common no start condition. I guess I am going to get a new IAC now since another code came up.
Well, my question is it came up with two other codes also:
P0171 - System too Lean, Bank No. 1
P0174 - System too Lean, Bank No. 2
Do you think the P1506 (IAC Code) made the O2 Sensor codes show up or is it really the O2 Sensors? I just changed my two upstream O2 Sensors around 90,000 miles. Should I get a new IAC or try to clean it again?
Ford F-150 - 1997-2003 :: 1999 - Code P0500 - Speed Sensor Has Been Broken Off
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....

Looking for some experience/recommendations for the "what to do" and "in what order" for an error code. Recently the "SERVICE ENGINE SOON" light came on and has stayed on for the last 2 weeks. It has don this before after a heavy rain but went off after a few days but not this time. I took it to Advance Auto who hooked it up to a Trouble Code Reader and got back "PO174- Bank 2 system to lean". From what I've read from the Haynes book and other forum postings this is either a O2 sensor issue or a intake manifold gasket issue? Does this sound right? Next is how to go about addressing this issue in a systematic manner so as not "fix" 10 things that don't need fixing and not running to mechanic and paying a buttload for something I can do myself for less.

What that means? The check engine light is NOT on but I looked for a code because my truck is idling rough, and when driving, when the overdrive kicks in, it vibrates really bad. As if a bad U-joint on your drive shaft. The truck has been in a field for about 5 months broke down so any clue? Haynes manual says nothing about P1000.

I'm getting the p1131 error on my 2000 xlt f150 5.4l. I know it's usually a vacuum leak on the pcv hosing, which I did have at the back and replaced as well as other softer joining sections(3 to be exact lol), but I'm still getting this error. Changed out my plugs and cops(as they needed it) and the back two plugs on both bank 1 and 2(plugs 4&8) were both white! Since this is an obvious indication of a lean burning cylinder can I make the assumption my most likely problem is dirty fuel injectors on those cylinders?

I was driving along today and my Check Engine light came on. I stopped at the nearest Advance Auto to have them pull the code and it came up with the P0420, Catalyst Efficiency Below Threshold (Bank 1). I asked what could cause this and they mentioned that the fuel that was put in could be causing it. They didn't mention any other possible causes. Any others? I'm thinking it could be the fuel because the last gas station that I stopped at and filled up at is one that I never go to, and maybe just got a bad batch of fuel.

I'm getting an error code 2-7 (flashes two times, pauses, then flashes seven times) when my truck starts up. It does this cycle twice then stays on permanently. It has only started doing this since last night when I replaced my factory tape deck with a factory Cd player from a 2002 F-150.

So I just bought a 2003 f250 v10 and I've plugged in my code reader and it couldn't get any info, so I took it to auto zone and they got an error code. I took a test lite to each little connection on the port with the ignition on and only got power to some of the metal connections on the port. So I'm wondering if all the little connections should have power? If so where should I start to look to find the problem?

Well I thought my truck was 100%, and I was going to installed a Chip. I decided to get my Forscan up and running to check and make sure.
The Buzz test Passed with no problems.
The cylinder contribution did not pass. I got error code P1464, which Forscan said that #8 failed. FYI, I turned the A/C on and the test failed. I ran it again with the A/C off and it failed again. I might have the wrong code
I then went to where you could select the gauges to view(PID's). And I saw where you could select all the cylinders injectors individually. I forgot what it was called, but all injectors were reading close to 0.0% at idle except for #8 it was reading 5.55% to 5.88%.
I am hoping this is good news, since I rather the injector be bad then a piston ring or valve. I just got the Forscan and was wondering what other test or other things I could check to narrow the problem down before removing the Valve covers. The truck runs great and there is no miss and it turns over smooth. No blowbye, just runs great. It is a 2000 F-350 dually with just over 202,000 miles

I had been having battery issues with my 97 ford f150 4.6 liter for the longest time, thought i had a short under dash, i pulled entire dash out, disconnecting bat first of course, and inspected all wiring harness connections and fixing my issues and putting it all back together. now with new bat and all put back together i am now getting the airbag light flashing 5 times then 2 times (error code 52) i know it has some thing to do with power failure or backup battery, but now with the new battery in i cant seem to get it to reset. How to do this?

I'm trying to get my truck smogged and having problems w/po475. A friend of a friend said it was the DFPE sensor. So I bought one but can't find where it goes. On YouTube it is only listed for F150's and gas motors it seems. I have a 00 f350SD 7.3, do I even have a DFPE and if so where is it located.

2000 truck, 334k, automatic 2wd, stock. Have low power, 11psi max.
Permanent p0472 code, can't clear it even temporarily. The moment I turn the key to Acc, code is there. It's the only code showing on Forscan.
Tried 470ohm 1/2watt resistor, in two turbo pedestal sensor connector wires, no change. Forscan shows 0.0-0.6 psi EBP value when running.
No change with pedestal sensor plugged or unplugged. Resistor or not. Truck starts and runs good, low power is the only issue.
Sensor and tube are new. Seems like wiring is bad, where to look next to track this down?

But if I unplug any bank 2 coils and engine makes a difference.
