Ford Excursion :: 2003 - Replaced Alt And Battery Now Got Error Code P0231?
Apr 10, 2017
I bought my Excursion about 3 months ago. So far I've replaced the Alt and battery all because it randomly die on me. I guess no the issue isnt the Alt or battery but an error P0231.
P0231 Low Voltage Fuel Pump Secondary Circuit
[URL]....
I've replaced what I thought was the fuse but not 100 percent sure. I cleared the error message and now it's still doing the random turn off. Now I'm getting an error P1000. Tried google search with very little success.

Okay, I am having issues with a 1999 F250 XLT 7.3 with diablo programmer. I have searched and searched and have tried everything we could think of and it is a no go. The truck will crank, hesitate to start, start and die, other times it will only crank and not run at all. We can make it stay running by hitting the accelerator. The only code we were getting was the cps code, but that is suspected to be because of the excessive cranking and no start times. Previous to this issue getting this serious it would stall randomly, at idle, going down the road at constant speed, slowing down, or accelerating. We now have code P0231.
Through this we have tried:
IDM
(loaner) ECM
removing Diablo
3 CPS
shaving down CPS
Shimming CPS
IPR
Fuel pump
relay
fuel pump fuse

I got a 2006 F250 6.0 that won't start. It turns over perfectly. What I've done so far was change oil and filter, along with fuel filters. All fuses and relays are fine. I payed for the scan gauge 2 and monitored FICM SYNC, FICM voltage, ICP, AND IPR. Every thing checks out besides ICP. The ICP is reading under 400. So I unplugged the ICP. Still no start.
I decided to spray some starter fluid in the intake and turn her over. Boom starts right up and runs fine. I even drove her around for about 20 min. I get home and shut off the truck. wait a few minutes and nothing dead again. So ICP is low but the truck runs fine after some initial support from starter fluid. What I need to do next? I don't want to have to take it into the shop for something stupid I could do myself.
Also the code its throwing at me is P0231 Fuel Pump Secondary Circuit

I successfully replaced the HV battery on my own and it was so easy even this girl to do it! I drove the car about 300 miles when I got the triangle of death warning light again yesterday. I took my 2002 Prius to the dealer to read the codes but how to borrow a scanner (or whatever) from Autozone and do it myself.

So from the beginning the car wasn't coming on. It gave me error "p" said my parking break was not working properly and needed to be on a flat surface in order to work. We jumped it and replaced the battery shortly after that. The car will turn on but the actual engine is not turning on. The display screen has a little car with a red exclamation going through it. The dashboard also has all the lights on. We have tried to jump it from the relay at this point but it wont start now to where before it would.

Black Beauty finally gave up. Replaced battery, replaced fuel pump relay. Would only run with starter fluid sprayed into the air intake. She'll crank but not start. Here she sits at the dealership.

I am getting an error code of 1201. Is this the ERG valve? How do I change out? Looking for Pictures or diagram?

I had my hybrid water pump replaced (free, under recall) about a month ago. Now the check engine light comes on intermittently, and it's with error code 1121 (Coolant flow control valve sensor stuck). I've seen other people on this forum hypothesize that the work could cause this error (if not bled properly, leaving air in the system). But my dealer said the work had nothing to do with this error and I need to replace the control valve. How to suggest to my dealer that it could, in fact, be due to their work and that I think they should fix it for free?

I successfully replaced the radiator on my 2003 Ford excursion (LMD, V10, gas). I filled her up with coolant and started her and turned on the air full blast.
Noticed though that she is now leaking somewhere between the engine and the transmission pan.Where and what to check?

My 01 Prius is not charging the 12V battery and I have error code P3001. Everyone on here said P3001 is the HV battery ECU. (which I replaced with one from the Junk Yard and still get the error code)
I charged the 12V battery over night and Autozone says that its ok. They tested it with a little machine. The only other thing I can think of is that the Inverter DC-DC converter part is bad. How I can test that? (is there a way other than replace the inverter?)

Have replaced dead cells on wife's HV battery over a month ago. Threw this P0a80 code today and will barely move. She idles into dealership and they say it's the battery, really!

I have 2005 Prius with 300k miles. I started throwing P0A80 code. I removed the battery and checked all the modules and found 2 of low voltage, ordered them from Ebay and replaced them. I placed the battery back in the car and started the car but got P0A80 code again. I purchased the grid charger from Hybrid Automotive and connected it according to their instructions for 24 hours. I drove a car but got the red triangle again and P0A80 code again. I removed the battery again and tested the voltage of all the modules and these are the readings:

VSC, ABS triangle warning! Error code POA85 ... We took the car apart and basically found the error with the fan it's not working. When you connect the battery to the fan it's working perfectly. The fan motor resistor is overheating is this the problem? Or should it be very hot.

So of course it has to happen 3 weeks after my warranty expires. My CEL comes on and I have it read and the result is P0440. I find out that my wife has a habit of topping off the gas tank and so I am thinking that she has probably ruined the charcoal canister. It is something easy to replace?
I have an 06 limited edition... Yes, she will not be topping off any gas tank anymore.

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?

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.

Well, I bought a used 2003 Escape for my daughter and without thoroughly researching the airbag light, now have a problem. The light flashes twice, pause, then once, so I think this is error code 21? I cannot find anything on what this code is and how to fix it. I disconnected battery for an hour and now I get 4 flashes, pause, 6 flashes, 46 error.
