Engine light came on two weeks ago. Had the code read at Advance Auto Parts. Code = P0420. The only performance issue was that it stalled when I started it the other day for the first time since I bought it last fall. Are there any other clues to tell what it could mean (catalytic converter vs. 02 sensor vs. anything else)? Is it really worth trying some kind of catalytic converter cleaner product?
View 1 RepliesI have a 2002 Forester I have take it to 4 shops and each shop tells me something different. First 2 say to take it to the dealer and have them flash the computer. The dealer says that it is a faulty drain valve and the fourth states he has never heard of a drain valve. Hook up to a scanner and can not clear light. Unhooked battery for 30 minutes light was off for a minute but came back on. Getting extremely frustrated!
View 11 Replies2002 Subaru Forester I took my car to the Auto Zone to read a check engine code. It came back as being a "knock sensor". Besides that I needed a battery, and when the guy was putting it in he said my engine was moving too much and that I probably needed motor mounts.
I was looking at a discussion back in 2010 and the Subaru specialist told the person needing motor mounts is rare for a Subaru, is that true? I'm taking it to a mechanic, what should I expect? how many motor mounts does a subaru have?
I have a 2001 forester. it had a misfire which has been fixed but I can't get the "check engine" light to turn off.
View 3 RepliesOur beloved 2004 Subaru Forester has the check engine light on. We've been told that the 4th cylinder has either low or no compression. Is this fixable/worth fixing? Would you replace the engine? The car has 183K miles on it, and runs great! It is stuttering now, due to this issue, but otherwise - runs great and is in good condition!
View 11 RepliesI have a 2007 L.L. Bean Edition Forester. The cruise light is flashing and check engine light is solid. I am well into my retirement age and nearest dealer is about 2 hours away. Is this something that local mechanic can fix? He is very good, but not Subaru schooled. I'm afraid to drive it now.
View 2 RepliesI just bought a 2006 Subaru forester with 130K miles. Recently, the check engine light came and at the same time the cruise control started flashing. I brought it to the mechanic who said I had a bad catalytic converter. The car seems to be running just fine and now a day later the engine light is off.
View 3 RepliesThe check engine light on my 2006 Subaru Forester with 92,000 miles came on recently. A scan revealed the engine was running lean. After three more trips the mechanic determined the rear O2 sensor was bad and replaced it. This was the only part replaced. Now the computer is sending code P2097; Post Catalyst Fuel Trim System Too Rich Bank 1. I have read it could be anything from the catalytic converter needs replacing to "resetting the adaptation values."
View 2 RepliesI have about 200k on my forester. Friday when I was leaving work I cranked it up and it made a loud knocking sort of sound. I drove it home (about 15 miles) and on the way the sound lessened. It was louder when the car was idling but she made it home ok. Next day, started the car and it happened again. Not more than 50 feet up the road we stopped at a stop sign and it sounded like a semi was starting up around the corner. Much to my dismay it was not a semi but my own car. Engine shut off. We pushed it back to the house and tried to check it out the next day. This time, we started it, didn't go anywhere, and within 30 seconds it turned off. Same loud knocking sort of sound. The confusing part is that all of this happened within two days. There was no gentle sound leading up to it for a few weeks or even a few days. Knocked on Friday, shut off on Saturday. What could be going on?
View 19 RepliesIs it necessary to check (or change) the fluid levels in the CVT and the differentials?
The manual has the following confusing statement for those:
Continuously variable transmission fluid. It is not necessary to check the transmission fluid level. Check that there are no cracks, damage or leakage. However, the fluid inspection should be performed according to the maintenance schedule in the “Warranty and Maintenance Booklet”.
The Maintenance Booklet list inspection every 30k miles for : Transmission gear oil, CVT fluid, front and rear differential gear oil.
Another question, how is the Transmission gear oil different from the CVT fluid? And should there not be a third differential, or is that part of the transmission?
On my 2002 Subaru Forester (137,000 m), the check engine light came on. They diagnosed and repaired O2 sensor. About 300 miles later it came on again, this time they said the catalytic converter was cooked, and they blamed whatever caused the O2 sensor to fail (or the O2 sensor failure itself). After the repair (about $1300 and 30 miles later), I discovered that the engine oil was so low that it was not showing up on the dipstick (tho the oil light was not yet on). The shop (after admitting that they did not check the oil while it was in there) said it was related to catalytic converter failure. Does this make sense? I have only gone another 60 miles since the oil was refilled, but so far it looks OK. Should I be on the look-out for anything else?
View 16 RepliesI have a 2002 subaru forester that will stutter and backfire without throwing a code, but not all the time. i have had it hooked up to a computer to check the O2 sensors and they are fine, it has a new Throttle position sensor, knock sensor, plugs, and catalytic converters (all put on in the last month). I have called a dealership and they have not heard of this happening, so this is my last resort.
View 15 Repliesmy girlfriend has a 2002 forester and it is making a very loud noise while driving, sounds like a helicopter coming from the front/right. when you let off the accelerator it changes pitch and sounds like more towards the middle...checked for axle play or anything rubbing and things look ok...very confused, i'm a former VW tech and i've never heard this noise before
View 7 RepliesI've a 2002 Subaru Forester, manual transmission. The gear shifter is very loose. While in any gear, the shifter can move to anywhere. For example, when in second gear making a left turn, the gear shifter will flop to the right side near where third or fourth gear are. This doesn't change the gear of operation that the car is in. It just makes it a bit of a challenge to find where the gears are. Sometimes it is a challenge to find reverse.
We've had the shifter bushings replaced and that tightened things somewhat. But it is still very loose.
Mechanics have said that there is nothing wrong with the motion or the way the linkage operates the transmission. So the problem seems to be in the gear shifter.
Is this common on this car?Is it a sign of a bigger problem?What can be done about it?
Out of the blue, our Headlights and Parking Lights would not switch on. Checked the fuses--OK. Tested the Relays--OK. Tried a used switch from my mechanic--no change. In the course of doing that, the Parking Lights came on and would not turn off. Tried disconnecting battery, locking/unlocking with the remote and starting it with the remote--no effect. Had to remove lightswitch 20A fuse to turn the P-lights off. Signals still work ok--with either switch. The car does have a HarmonKardon satellite radio which I've never used but have to turn off every time I start the car. I believe it has some sort of security system which annoyingly flashes a red button which sticks out of the dash.
View 1 RepliesI have a 2002 Subaru Forester L with 178,000 miles on it. I just had the valves adjusted. I have replaced the coil pack, #2 injector, plugs, wires, and throttle position sensor. I have also cleaned the idle air controller. The car only shows sign of a miss when it idles. It gets great gas mileage otherwise. I am at a loss on what to do next as the car doesn't have a MAF sensor, I can't do anything with it.
View 19 RepliesI have an 02 Forester that has 413,000 miles. It needs appox 2 qts of oil @ 4500 mile intervals. Is that too much? Is it going to start needing more oil sooner? I guess I am asking if the end is near?
View 19 RepliesMy 2002 Subaru Forester is making this weird clicking noise and unlocking as I drive. It seems to get worse at night, and especially when turning left, or braking. My mechanic can't figure it out.
View 10 RepliesMy Forester was dead one morning and when I went to jump it off my pick-up in a hurry I did the age old palm to forehead and didn't pay close attention to the posts on my pick-up battery. Crossed the posts.So I began working through the common known issues.Replaced the main fuse. Didn't Start.Replaced the battery. Started... Car shut off while driving. Did not sputter out, simply cut out like turning the key off.Started right back up.Positive battery cable was loose. Replaced it.Grounds are good.Alternator output is good.So here are some more details on the car shutting off.
This last time as I was coming home from the store and the car shut off on the main road through town. I had enough momentum to get off to the side of the road. I tried to start it and it would turn over. Normal turn over sound but the car wouldn't start. I took a minute to check other electrical things in the car with key in the "on" position. Radio worked. Dome/interior lights worked. But then I noticed something strange. None of the dash lights came on (Car is not started but key is in "on" position). The windows did not work either.It started after about 5 minutes time and I made it home, forgot to roll the windows back up. Turned key to "on" again and couldn't roll the windows up. Got out of the car and came back after about 5 minutes, turned key to "on" and the dash lights came on the windows rolled up.
My subaru forester, 2002, with low mileage (40K) had routine maintenance 2 mos ago. Now sounds like it revs when in idle, and today began hesitating when I accelerate (a few seconds or so). I plan to take it in but wonder if there's insight before I go in cold (I know nothing about cars). Read on forums could be 02 sensor.
View 1 RepliesMy car is about 140K miles. It is a 2002 Subaru Forester. For about one month now, my car has this loud metal grinding sound from the rear of the car when I try to climb a pretty big hill. (The grinding sound is rhythmic, it is more like Click Click Click, but loud and metallic). After the climbing, the noise will slowly goes away. The noise never more than 10-15 seconds. The car functioned normally during all other driving but climbing this big hill. ( which I need go to through it at least 3 times a week). What could cause this?
