Hello guys!
This is an 07 Outback, 2.5 4EAT.
The car drives perfectly, the transmission shifts great but today, while parking, i opened the door to better see and avoid an object and i noticed a weird and tiny noice come from under the car.In quiet street i did accelerate and i the noise do change rhythm when shift from P to N and to D.
i uploaded a video to Youtube so you can better appreciate.

HI guys! thank you a lot for the time you spend helping me with this
i decide to do a rebuild, all electronic was bad, they put a new diode card and an used regulator, and gave me warranty, everything working fine by now
Thank you! -
ok i will check thwe fuses, ground and both terminals of the fuse
i will wait an hour since i have to pick up a frind at the train stop and i will save time and ccharge by turning the car on and doing the test when i go out to pick him up
its a 10 minutes trip i hope not to broke something in the car and that the battery last for those 10 minutes
-
I need to know the model and year engine size, etc. of the car, and have the link to the fsm to be that specific.
its a Legacy 93 ej22 2.2 liters
(i have checked all the fuses they all looks good
-
Look for rhe engine electrical schematic. Find the alternator section. It might take a little tracing of lines, etc. To figure it out, but it should show what fuse is in the circuit. It should show what pins go where.
On gemeral, 1 wire has to be going to the alternator light or indicator lights. One has to be fed power via the ignition switch. Those circuits have to be intact and functional for the alternator to work.
so, that should be locate dun der the dash right? and out of the fuse box
-
I worded part of that oddly. The fuse isn't likely specific to the alternator, it is likely for engine systems power, and the alternator just happens to be one of the things fed by it.
thats what i thought, i watche dall the fuses and none of them are named soethingrelated to alt or engine
i have the service manual
-
Oh, the small wires, there are usually at least 2 small wires from a connector on the alternator that go to the alternator light, ignition switch, etc. What exactly depends on the car.
Going by the readings you gave above, the voltage is way low for with the engine running. The voltage on the alternator terminal reading lower than the battery post indicates no output from the alternator. So either te alternator is dead, or one of those small wires isn't doing what it supposed to. It would be worth checking fuses. Not with an ohm meter, not by looking at them, but by measuring each end to ground. With the engine running. Both sides / ends of a good fuse should read close to the same voltage.
what fuses?
the ones in the cabin or the ones in the engine compartment?
-
OK
i need a reliable solution, a solution tha last at least for some nice years
used alternators are a whole matter of luck, i have heard of used alternators that last 5 10 years and others that last only weeks....
the best solution would be a new enuine one but... before reaching that top solution...
do you suggest me to try for a usend one? an dhow to choose one that could last?
or..
i was watching this one on ebay, what do you think?
osed one sin my country ranging from 40-60us
that one from ebay woul dcost me about us150 (with the shipping to Dominican Republic)
-
those small wires you mention.. are all inside the alternator?
my fear is if the problem is not the alternator neither the battry it scares me a lot that could be something else
-
battery was dead so i am charging it (slow charge) thats why its voltage is 12.3
when i started the car the voltage drop and fixed at 11.87v
voltage at alternator terminals 11.85v
the earth is very good very low almost 0 resistence
and the test of alternator frame to battery negative pole shows almsot 0 resistence...
everything points to the alternator
-
The reading for the alternator output is the one big bolted connection, fat wire.
The last reading is voltage also, with the same conditions, idle, reved, off.
give me 3 minutes i amgoing to doit
-
The readings on the battery, probed right on the posts. Yrs everything wired as it should be.
Alternator terminal to alternator frame.
A bonus / double check put 1 probe on the alternator frame and the negative battery post
Great!!
thank you a lot for your help
need chelp, Sorry for my lack of experience
"Alternator terminal to alternator frame."
what is alternator terminal? the connector with 4 clamps (how could i doit without disconecting it then? or the bolted terminal?
the last thing (the double check) is for checking continuitti right?
-
You need a voltmeter.
Need measurements to diagnose .
Voltage at alternator output terminal
Voltage on battery posts.
At idle.
At 1500 to 2000 rpm.
And with car off.
i can do tha right now
those voltage at the alternator output, and battery.. were do i ge tit, putting the votlmeter pins on the battery poles (with cables on?)
-
the battery is new and the alternator i am sure is not charging, but could something lese block the charge form alternator to battery, i mean could the alternator be good and the charge not passing to the battery due something extra?
-
Hi guys
after 4 years of
random battery discharges, two new batteries (one exploded), yesterday,
the battery and brake lights came on, and today the vehicle shut off
while running.
everything points to the alternator but... i had
an used alternator in my house and i did the install, and jump start the
car and 10 minutes later int went off again, TWO ALTERNATORS?
what other thing could cause the battery not charging?
-
I assumed you have an EJ subaru which have two sensors in the US. What exactly is your car?
Subaru Legacy 93 L
Station Wagon FWD
USDM

If you're talking about the rear o2 sensor, without a cat the second method will generally work better and keep the engine light off. The rear o2 sensor doesn't do a whole lot for engine tuning, it's mostly emissions.
If you're talking about the front sensor, it needs to be fully is the exhaust stream or you'll have the wrong mixture.
thank you for answer
this vehicle only has one o2 sensor
-
Hi!
i have read that on this model there is not a
really an appreciable difference in gas mileage, i know it is for
keeping the gases wihtin the manufacturer range... but usually it
improves the fuel mileage since without it (the o2 sensor) the system by
default would set to a rich mixture...
after installed the new
o2 sensor, the check engine light went off and the mileage increased by
0.6 or 1mpg (several method to measure)
but i wonder
please, check the image
i know the sensor should be installed like the no. 1 example
BUT mine (after relocated, because this vehicle had catalitic removed)
the
muffler guy installed like the no. 2, he told me that the o2 sensor
does not need to be in "full" contact with the gases, that only needs a
"little" doze of the gases in order to make its job....
not too
satisfied with this, i wanted to ask you if i should go back to the
muffler shop and make him to desolder the o2 sensor socket again and to
make him to solder at its correct level so the part of the o2 sensor
that must be exposed to the gases is fully exposed?
just like the no.1? -
i checked that switch and the solenoid is fine too, i want to check the relay, how do i get access to it?
-
Hi guys!
This is a 93 FWD Automatic Legacy
i had several years with the shift lock system not working properly, some times unlock when i depress the brake pedal; often does nothing and then i have to manually unlock it (pressing the button)
but now, i just decide... i wan tot pursuit the problem and fix it! (with your help, of course)
i just disassembled the shift lock plastics.. and i used my multimeter to figure it out that there is no voltage at the solenoid when i press depress the break pedal
so following back the chain.. i guess I should now test the solenoid relay.. am i right?
Where can i locate it?
-
problem solved, TCM bad
-
HI!
i am having a similar problem
but mine is stuck in 3rd!
it has new fluid, new filter
the test I have done:
all the transmission sensor and solenoids are perfect (I followed the manual procedure for testing and they are all within the range (measuring the resistances in the transmission conector)
but the throttle position is bad,
-the resistance between pin 2 and 3 was 8.8 instead 12
-the resistance between pin 2 and 4, fully open, was 0 - 1.7 instead 3-5
-the resistance between pin 2 and 4, fully closed was 8.8 instead 10-12
and I haven't been able to test the TCU connectors, I did pull out the TCU and I open it and everything inside looks pretty fine, no burn smell no blown chip
can the TPS put the transmission in failsafemode?
I want to do the test tot he TCU connector but I don't know what is what I have to do, I have to measure the voltage of the TCU connector (female ones) or the harness connector (the male ones) (I don't know which voltage I would meter to the TCU connectors if I remove the connector to accss the pin.... duh..) but is what I have to do to measure the voltage with the connectors in ints place (in the TCU, and to touch it wth the multimeter's probes in the back side of the harness? while connected to the TCU?
sorry maybe bad written sentences due my little english
any help will be HIGHTLY appreciated since I am in a remote area, and I use that car for moving my grandma who is very old and that's the only we have for that purpose thanks to its frameless windows (already gone in latest models, very bad from subi)

Next chapter
Yesterday I began a vigorous search for any loose connections and ground faults. I happened to look down at the passenger side CV axle and noted that it was connected but, the axle stub was extending out of the tranfer case about 2 inches. After disassembly and replacing the axle stub(?), back into the transmission I took the car for ride, guess what the car drove perfectly. So far so good.
I have 3 questions
1. How did this happen?
2. Why did this affect how the car drove?
3. Why did the car even drive at all?
Hi William!
i have almost the same syptoms you had..
and what catched my attentions of this post is what you mention about the cv axles, in my case yesterday i noted that both CV axles have a little play, an di want to know if thats normal, mines are not so separated from the case like 2 inches, mines are fitted well (i think so) but are not thight i can move them with my hands and i wonder is can someone tell me if should have little movement or should be able to shake it at all wiht my hands
(little background; last week i sent the car to the shop because was leaking oil and they suggested me to remplace all the seals (the kid with all the engine seals) which i found ok, the give me the car back with no leak but have some issues like that roughness when acceleratin, a little lack of power, a huuuuuuu noise comming from the timming belt and there is a missing bolt that connect the engine with the transmission...
