p1413

[shoprofit]

Hi folks, new member and have found this forum to be extremely helpful. Hope I put this in the correct place. Any help with my issue will be appreciated.
My situation: Bought a 96 135k, mint interior and loaded, paid $1300, welded cams, new bridgestones, and everything works (except keypad entry light, oh well). Anyways, it had a 0301 code, needed an east west brake line, and air isn't blowing cold. A little surface rust in a few spots, and golf ball size hole in drivers side rear fender, low right behind tire.
What I've done:
Moved 1 coil to five, then to 8, misfire follwed me, replaced coil, issue solved. While doing that it threw a new p1413 code and I noticed a whistle at start up but unfortunately the whistle seems to have disappeared. Removed rear intake completely, as opposed to just lifting it out of the way like the first time while changing out coil 1. Did this to check for any broken/missing vac lines as I lifted fairly ******* it. I'm sorry I did that. Found nothing and reassembled. Removed bumper shroud/splash guard and checked SAI pump buy feel and it runs for the 30 seconds or so and shuts off. So I disconnected the hose that hooks to the metal tube just below the egr (I believe this is some diverter valve?) cold started the engine and can hear the flow as it is fairly loud, then after the 30 secondds it shut off. P1413 says low voltage but the pump is running, I'm confused? I clear the code everytime, the initial start up the code stays off and the second time you start it the code comes back within 5 seconds or so. I assume it's because the PCM doesn't see it initially.
I also read that a misfire will disable the A/C, anyone know for sure?
While I'm off to attack it again, any replies will be thoroughly examined and greatly appreciated. BTW my buddy wants to give me $2,200 for it, but in NY it's worthless with DTC on. Thanks again...

I had the same code and ended up replacing the SAI pump but it didnt fix it... I finally found the SAI relay that is mounted on the side of the bracket that the SAI pump mounts to.. I replaced my relay and the code went away. I however also had my battery die do to the alternator not charging after it got hot and the whistle noise of the alternator would go away and the battery light would not come on(when starting the car) once the alternator stopped working. I would let it cool off for awhile and the alternator would make its noise again and charge again until it got hot.


good luck and hope you get it fixed!!!

Thanks for the reply, I just got the motor out (well, the bracket anyways). Hopefully it's the relay since that is easier than dropping the frame to get the motor out. I do want to get it on the bench though and have a look at it. I'm now going to test the relay and motor as soon as I find that thread outlining it.
Side note: I don't believe the pump is working as I once did. It appears the diverter valve opens and what I was feeling and hearing was the exhaust.

 

[PrestonsSHO]

That motor will squeeze out between the lower radiator brace and the starter.... it is tight as **** but I got it out.

here is some info for ya hope it helps
Vehicle Application: 1996 Ford Taurus SHO 3.4L 1998 Ford Taurus GL 3.0L, GAS, Vin U
1997 Ford Taurus GL 3.0L, GAS, Vin U

Customer Concern: Trouble code P1413.
Tests/Procedures: 1. At the Powertrain Control Module (PCM), ground pin 70 Brown (BR) wire. With pin 70 grounded, the Secondary Air Injection (SAI) pump should run and battery voltage should be present at pin 5 White/Orange (WH/OG) wire.

2. If voltage is not present at the WH/OG, and the pump is not running when grounding the BR wire, check fuse 8 30A in the engine compartment fuse box.

3. If the fuse is OK, go to the relay located near the pump behind the front bumper. Verify battery voltage is present from fuse 8 on the White (WH) wire. If so, try grounding the BR wire at the relay, recheck the WH/OG. If still no voltage out, then replace the relay. Also try jumping the WH wire to the WH/OG to run the SAI pump and make sure it sounds OK and does not blow the fuse.

Awesome response, I'm off to test it. I just found SHO123's? post but yours contained the pcm info that will help a lot. Thanks for your time. I'm off to the garage and will post any results, hopefully good ones. Oh, as you know it's a 96 hopefully all gen3's are the same and I can wiggle it out as well.

 

[shoprofit]

Hmmm, don't have to remove motor. Direct power to the pump and it works fine. Have power at the white wire going to relay, guessing it's not making it to the wh/or to power motor, so it's off the u-pull it tofind a decent one. I would have preferred to test it at pcm but it seems easier to try a new relay first. Thanks again.

I bought my relay from napa it was around 50-100 dollars but cant remember exact.glad I could help.... I am not 100% familiar with these cars but I work at a napa auto care and have worked on cars for the past 20 years and still learning.... but there are guys here that live and breathe these thing thats why I joined up here they have been a good group of guys.


no problem on the help hope it works out for you.

 

[SHOZ123]

I would rewire the thing and use a $10 bosch style relay 40A. That is what Ford has done with the newer cars.

But I have a OEM relay if your interested.

Or you could get a tune and turn the damn thing off.

update

It was indeed the relay. Light out, anyone wanna buy a green 96 loaded with 135K.?
Preston, it wasn't easy finding any of the cars you listed at the local boneyard. So I just started looking at all the 96-99's. I found the relay and sai pump in a 97 taurus, and of course the taurus emblem was misssing! I think it was an SE, maybe. The pump actually said SHO right on it. To be safe I grabbed a second relay off a 99 mercury sable which is the one I actually used.
Now I have to try and get more brake pedal, putting the rear on the ground made a big difference, but it's still lacking.

Any input on a misfire shutting down the A/C?

Thanks again to all who provided info.

 

[PrestonsSHO]

glad it worked out..... on the misfire issue someone with more knowledge of these cars will have to help on that good luck!

lol... mines a black 97 SHO with 117k want a black one

Value

Well it's fixed so the easiest solution I guess would be to try it.haha
I checked you car out on youtube, nice, ...is that a receiver hitch I see?

So what's a green welded 96 worth, loaded, interior's mint, body has a couple blemishes, new bridgestones? No pics yet, still on jack stands. I bought it off my buddy, he kept a towel on the rear seat backs since 27k miles and stored the original floor mats, he's ****, insides like new. He provided me with a sheet long list of everything done with every date. Tranny done at 95k Another buddy offered me 2,000 but I thought it was worth more, but I'm starting to think maybe not.

 

[PrestonsSHO]

well I paid 2500 for mine and I have put over a grand in it now... new tires,alternator ,exhaust,air pump and relay,battery and now a abs unit on its way and also SHO gauges.

25 years or so seems to be when most cars that are going to be rare start to appreciate again so from a resale standpoint these cars are not yet starting to go back up in price. That will take another 8-10 years, I would guess. If you want to make anything decent on it, you are looking at holding on to it for some time yet. You might be able to get more than $2k for on in excellent shape as you describe, though, if you are willing to wait on a motivated buyer. Not a huge amount more, though.

Thanks for the input Stephen, and I agree. His offer was MOSTLY based on its condition and it's trasportational use for his niece or his daughter, he could really care that it is a SHO.
Anways, it started running rough with no MIL, was able to locate a bad coil
(5). Ordered one for $27 with shipping.

As I have the same P1413 code on mine and made a lot of researchs on it. I rode almost all the threads on this problem and it's seems to me that the relay will broke often than the pump itself (at least, it's the easier way to go first). Even if I want to keep the car in good shape, I don't want to buy a new ABS relay (actually sacondary air pump relay) at 130$ (us)... It's just a relay after all ! Here what I found on this relay :

Part numbers:

F3LB-2C013-AA
F3BL-2C013-AB
F50B-2C222-AA
F57B-2C222-AA

Ford vehicule having this part (bigger cars, maybe easier to unbolt ?) :

Lincoln Mark VIII : 1992-1998
Lincoln Continental : 1995-2002
Lincoln Navigator : 1997-2002
Ford Explorer : 1995-1997
Ford Taurus : 1996-1999 (not on all models*)
Mercury Sable : 1996-1999 (not on all models*)

*I had 2 canadians Taurus with Vulcain motor before and one had the ths SAI pump and one without. I precise canadian because this system is mostly for Californian laws if I recall correctly. Maybe Mr. Newberg can correct me with that...

Correct me guys if you found this relay somewhere else, I will add it here.

Hope it's will help, good luck.

 

[SHOZ123]

You can just as easily wire in a good 40A mechanical relay and be done with it. Probably can be had for less than $15.

 

[GEN 3 SHO FAN]

For SAI system, your solution it's probably the best Paul, no doubt on that. But I'm not an electician like you, it's why I tought replacing the relay will be easier to normal people with basic knowledge in electricity than rewire the pump with an other relay... I will study this solution (less money, little more time maybe but better reliability).

Thanks for the advice,

 

[GEN 3 SHO FAN]

Maybe you have photos of your modified relay... ?

 

[98SF19]

While this thread isn't too far gone, I wanted to ask about my current SAI behavior. Been steadily getting worse over the last few months: Car starts and I hear SAI start to hum/buzz loudly. But recently it sounds like it's been cutting out repeatedly and coming back on, as if something or someone were blocking the inlet. Last time I was under there (couple weeks ago), there didn't seem to be any obstructions and airflow into the hose was steady. No codes.

 

[GEN 3 SHO FAN]

I havn't studied this on mine yet but this system is present on Saturns of the same years and I know that the flow is easily blocked by sand, leaves and water becoming ice. I don't know at which height the system taking is air flow but the pump is very low (on the subframe) and things enter the system must stay and accumulate at the pump level logically. Maybe your noise coming from something blocking the fan partially...
