Jeep pcm

what if I find one with The same Vin (mine is vin N)

Also will my key need reprogramed

Cause is Code p0601. Are you sure I won't have to recode keys if I find a matching computer

I just don't know if it really needs fixed, engine light is on but I've never had any problems or anything with it

No. I just don't know the seriousness of the code as it runs good

And if I get one from the junk yard will are the numbers such as S/N number and stuff all need to match my Pcm or just the Part number off mine

So all the numbers off the pcm, Not just the part number need to match correct ?

Just doing some research on the subject. I'm convinced there nothing wrong with mine, it runs good. I'm thinking previous owner unplugged something while it was running so it threw the code. I've had no problems with it. Neither did the previous owner.

I do not believe ohio does inspections. But it has 220.000k miles (it's my first car) so I figured if the Pcm does have a real problem it will probably last along as the rest of the cars life as the cars old. I'll be getting a new car in a year or so .

So with this code should I be questioning the reliability of the vehicle? Would it be ok driving long distance with this code

Where can I find calibration code on my Jeep

But if I find a Pcm that the numbers all matchy current is should work correct

I noticed there's a few different numbers on the Pcm what if only the part number matches will it still work .

So the real question is if I go to the junk yard and find a Pcm from the same Jeep as mine with matching Pcm part number as the one on mine will it work?

So I got in my Jeep and no power at all no lights radio gauges start. Nothing. Hooked battery jumper to it and it works fine what could be the problem

But it just started fine about an hour before that, also I know the battery had plenty of charge because it was still sparking when I unplugged it

Battery terminals are not corroded. So I guess it's the battery then it's a carquest one . I have no idea how old

I also forgot to mention something so this is how it went it was parked overnight. Then started and parked in driveway then about an hour later I got in it and the lights work bc I opened glovebox and the light was on but then I put key in ignition to roll windows up and nothing no power . Like a mysterious drain somewhere

Thanks .So new battery is my best bet ?

I believe it is good because I had it on charge overnight and it was fully charged reading 12.7 volts while the vehicle was not running

It's gotten even stranger. Now battery voltage is 12.2 go to start lights come on it clicks battery is dead all of the sudden. Then have to jump start it runs fine then when I shut it off then restart it, it almost dies dropping to low rpm for a second or so battery voltage also drops to for a sec as well and thenafter a sec of almost dying battery voltage gos up and rpms go to normal ?

Not yet going to tomorrow just looking at other possibities.

So I used a test light and car has a draw somewhere. Haven't found it yet but the light dimmed on one fuse could that be it ?

Would the light slightly glow for Pcm and alarm radio memory etc ?

I mean like would the test light dim alittlw for every car or is it supposed to be no glow at all

What is jb power ? It was in slot 15 in the fuse box the light got significantly dimmer after the jb fuse was unplugged

It's strange . Battery all electronics are fine until I crank over then it clicks dead . Maybe try cleaning terminals and stuff first ?

I just took a quick lookbefore. But taking a deeper look the terminal cables are dull looking. I'm gonna clean them both up

I don't see how corrosion could all the sudden make the battery dead as soon as u crank

It's very strange. The battery stays charged fine for days while sitting everything's normal until u try to crank it over . Every once in awhile when u try to crank it over it drains the battery . But the battery stays charged no drain or anything till u try to start it

That problem seems to be fixed Would you think that the Jeep would run cooler if it had the correct power steering fluid ? Since the fan is powered by the pressure from power steering pump if the wrong fluid is not giving enough pressure to power the fan it may not run full speed ?

What if the fluid dosent meant the specs for my Jeep? Ps . I have checked no damage or anything

Thanks . I'm gonna drain it and put the right stuff in it because the pp whine is pretty loud now and steering a bit weird at low speeds

I changed the fluid to correct type and now whine is really loud

I drove it for awhile and it still made noise . So I'm gonna check it later to see.... Is it possible my Jeep 4.7 gets 21 mpg doing a pretty consistent 45mph that's what it says average mpg is ?

It's says that on the overhead display btw

Lol . Was thinking the same because fuel gauge seems to move alot more than 21mpg

Anyways, earlier pump was still pretty loud when I drove it. I drive it about 11 miles after changing the fluid, hopefully the air works it's self out it as it didn't make much noise before. The old fluid was wrong kind and was foamy .

How can I bleed the power steering its still whining changing the fluid didn't help , the old fluid was foamy which leads me to believe there's air in the system

Seems like it, I was whining loud after I changed it. The whine has quieted some but its still noticable .

I'm convinced there's air in the system because old fluid was really foamy and after I changed it the whine is the same. Just like before

Does it help get rid of air in the system ?

So is the pump self bleeding or does it need bleed maunal

Also I do not believe it was whining when I bought it. It didn't start till i replaced radiator and I have to take fan and stuff out so I had took unhook hoses and some fluid ran out. So when I was done power steering fluid was a little low due to pulling the line off . I noticed it when I started it it had a whine and I topped it off but has had a whine ever since

Only power steering line I had off is the line that runs from pump to the fan . I'll check it out.

I'm confident that it's not the fittings though because I had some help taking the lines off from a person who's very knowledable of cars

But if there's a gasket letting air in wouldn't it let fluid out to ?

See when I check my fluid in reservoir it's not foamy , no bubbles or anything. The whine now is not to loud u can hear it but not much it increases a little as you turn the wheel and give it gas. I think pump may just be a little worn

Yeah it steering good . No issues other than when just rolling like trying to parrell park steering gets stiff for a sec.. would you happen to know if power steering fluid ms5931 comes in a red color ?

I wanted to make sure . Bc the power steering fluid I drained was red . So it definalty was the wrong fluid

So with it having the wrong fluid in it. And now changed to correct I driven it about 39 miles and the whine has quieted some . Is it possible that the whine will quiet even more over time since now it has correct fluid

Also I noticed I didn't drain all old fluid out I noticed resoviour still has red fluid in it . Should I get the rest out ?

I think the little bit of old fluid is pretty diluted by new fluid I drained it then added about one whole 32oz bottle and the 2nd 32oz bottle has about 8oz left in it. That put it to proper level

I think last time I looked, there was a little red mixed in with it in the resoviour.

Could the whine still be from the leftover fluid ?

This is the old fluid

So is this definalty the wrong fluid ?

I was thinking the same .although it Smells like power steering fluid

How much does this thing hold iv used two 32oz bottles and there's still red fluid

Do u know specs for antifreeze for my Jeep? is Chrysler MS 7170 ok for my car.

Coolant I have now says compatiable with Chrysler 2000+ . Fluid I looking to get to top it off says meets Chrysler specs and is compatiable with all green antifreeze

Seems like they both meet specs for my Jeep so I think it's safe to get the fluid to top mine off

I'll just get the same kind that's already in it to be safe
