View 4 RepliesGot a 98 Subaru Forester with 130,000mi. Good car so far. Just got a good deal on a scanner and it reports 1 code - PO0400. I see it mean EGR flow error. What is the most probable cause or a troubleshoot process to narrow it down? My repair manuals on the car are kind of lacking and I can't even find the blasted EGR valve! I thought I found it but I think it's the knock sensor.
View 14 RepliesI took my car to my previous shop for a P0325, Knock Sensor Circuit Malfunction. They wanted nearly $500 to fix it. My new shop said that I just needed some engine treatment and the code went away for a week and a half, but it came back yesterday, and my engine ran a little rough.
I heard what sounded like a very rough engine and it was my car. The technician came in saying that I was only running on two cylinders, but that sounds like far worse of a problem than I had been experiencing. They say that I need a $266.80 valve adjustment, which is all labor, but the total is $300 more than that:
Engine Light diagnostic: $44.99 Shop Fee: 35.00 Tune up package Remove and replace spark plugs: 60.03 Additional access time - remove: 64.20 and replace spark plugs: NGK Spark Plugx4: 9.96 Adjust Valve Clearance: 266.80 Pepguard Limited Extended Labor: 58.65 Warranty BWD Custom fit ignition set: 36.39
Parts: 46.35 Labor: 436.02 Other: 93.65 Tax: 6.55 Total: 582.57
Of course, my roommate, who is upset that I am not continually pouring fluids into leaky power steering and AC systems butted in and said the entire thing is preposterous. Problems with cylinder firing are invariably the result of bad spark plugs andor wires.
Well, they say that I need to replace those, which cost $46.35, the least expensive entry in the entire estimate. They just want to charge $124.23 to replace them.
Why don't I replace them myself and see if that fixes my problems?
They say that if the valve clearance adjustment does not fix the problem then I need new cylinders and valves.
Regretfully, I have a "service plan:""Engine: All internally lubricated parts contained within the engine block, cylinder head(s) or rotary engine housing(s); oil pump; timing belt or chain, timing gears and timing tensioners; water pump; engine block, cylinder barrels, engine head(s), rotor housing(s) if damaged by the failure of an internally lubricated part. Dipstick and tube; harmonic balancer; oil pan; timing chain cover."
I cannot imagine that it would cover a valve clearance adjustment and they would only cover cylinders and valves "if damaged by the failure of an internally lubricated part."
So, ride my bike eight miles tomorrow, replace the spark plugs and wires, and hope that it is enough?
My check engine light has came on and I received these error codes
PO441 : Evaporative emissions control system incorrect purge flow.
PO 455 : Evaporative emissions control system pressure leak-large leak.
PO 446 : Evaporative emissions control system vent control circuit fault.
Also only my driver side fan is working, may be separate issue?
This began as a troubleshooting exercise for a P0442 code (2002 model) indicating a leak in the evap emissions system. Often caused by simple things like a loose/poorly sealing filler cap. Not this time
It's a neat design, tucked away up in the fender well. Even sports a very effective stone guard (plastic shield) which hides all that tubing from view. But the shield also traps all the road salt and mud and packs it into the crevices between the tubes where it stays from one winter till the next. Even a powerful car wash probably can't dislodge the caked on mess once solidified.
I got a Ford f150 and getting the error code P0446 Evaporative Emission Control System Vent Control. My truck has burnt up 3 of these things already in the last 8 months. Why my truck keeps killing them?
View 2 RepliesSo 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.
I am getting a code for my 2003 Accent (65,000 miles). The code is P1401 and it is telling me the fix is replace Evaporative Emissions Canister. I asked my mechanic about 2 months ago about this and he wasn't too concerned.
We are not in an area where they do Emission testing. I will be driving back home to WI . and want to know if I should be concerned. The round trip is about 900 miles.
My 2005 Mustang w/ 4.6L is giving a P0456 code and also won't let me fill it with gas completely. I think I've narrowed it down to the canister vent or purge valve. Looking for narrowing down which would cause the gas fill issue.
View 7 RepliesI purchased a 2001 Subaru Forester about 4 years ago. Within 48 hours of buying it from a dealer, the check engine light came on showing the PO420 code. The car was running fine without any problems and it was suggested to us by 2 independent mechanics that Subaru is notorious for throwing this code, so we didn't investigate it any farther besides doing a fuel system clean/flush that was offered to us by the dealer.
Lately, the car has started sort of shuddering during acceleration so we figure it's time to look into this more, but just trying to figure out where to start. From what I understand, this model has 2 catalytic converters and 2-3 O2 sensors. I've been reading as much as I can on the topic and watching videos trying to figure out our options and whether we should try replacing the O2 sensors first or just go for replacing the whole shebang. I know we cannot afford the pricey repair of it all right now so the car will have to sit for quite some time before we can do that; however, if we can figure out how to do it ourselves, we could get it done much sooner.
My questions are:What is the likelihood that this could still be an O2 sensor issue considering the shuddering when accelerating?
What other signs do I look for besides rattling in the cats to know they might be bad?
I 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 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 RepliesHaving this code...
1 Fault Found:
02409 - Brake for Differential Locking Motor
012 - Electrical Fault in Circuit
Center diff wouldn't lock, but rear would... it worked part of the time, but would get the error and unlock itself.... cleared the code while we were out there, and it would come back.... I will be taking it to the dealer sometime soon.....
I am getting a CEL and the error code is p2187 engine too lean at idle. I have been reading around to try and find the issue, some seem to say PCV could be the issue. I have also read a test would be try and remove the oil cap while car is idling. I did this test and the oil cap was difficult to remove and the idle got really rough once removed.
View 2 RepliesMy r is throwing a p0601 sum error. I clear, it comes right back. I know the previous owner has it chipped at a garage that wasn't linked to any brand. I was planning on putting an apr/giac tune over it but now I can't (no money). I know this might mean I need a new ecu. Right now I plan on going to vw on monday and having them reflash the ecu bringing it back to stock...if it returns then i guess i need a new ecu... This sound right?
View 5 RepliesI have this error code on my VW 1999 passat 1.8T automatic car. How to resolve it. My friend reset it and CEL went off for few days and now it came back again. How to resolve it??
View 2 RepliesIt happened to passat. Once I hit about 75mph on highway I get a stop engine (oil presser low light). It flashes than goes off once I lower my speed. I checked all fluids are normal. It throws a 12 code an says oil passage blocked, cam positioning sensor, skipped timing chain. These are what the code says could be wrong with it. The car runs fine with no hesitation at idle or normal city driving. I have already flushed the oil with cleaner, and still getting the light.
View 5 RepliesI've got a golf tdi with a tune and straight pipe exhaust, and after I hit about 115mph I get a system error code. When I shut of my car, it dissapears and when I try to find it with a code reader, its no where to be found. What's the cause?
View 6 RepliesYesterday i took 300 miles trip to VA and my engine light when on. turn out it was p0480 code. I had check online and find out it was a cooling fan malfunction. I want to know any1 else have the same problem? also is this DIY problem? or should i bring it to the stealership?
View 2 RepliesI have a 2006 Subaru Forester with 95,000 miles on it. Earlier today the CEL (solid) and cruise (flashing) came on while I was driving. I believe it may have occurred as I was accelerating up hill. I filled up yesterday, so I tightened the gas cap when I stopped. On my way home, I stopped by my mechanic and they read the code; P0420 Catalyst Efficiency Below Threshold Bank was the code that was read. They reset the code for me but told me that the catalytic converter is what needs to be replaced.
My question: Could the light coming on be incidental (i.e., is it possible that it was a "blip" and my catalytic converter is okay?)? My mechanic said he thinks it is, and that my car should last me quite a bit longer. I am asking because I've put in a bit of money into the car of late and I'm wondering if I should just jump ship. I should say that the majority of the repairs are maintenance (e.g., brakes, tires).
My 2000 Forester has 96,000 miles on it. A few months ago, the CEL came on. At first it would turn off every couple of days but would eventually pop back on. I first thought it was tied to putting gas in the car, now I think it was just a coincidence.
Over the past two months, I have replaced the catalytic converter with a aftermarket piece (done by a mom and pop muffler shop) and replaced the front o2 sensor three times. The first two times, I used Bosch sensors from an auto parts store and had the code cleared. After about 50 miles the CEL came back on. Just yesterday, I picked my car up from the dealership where they installed a Subaru fron o2. After about 30 miles, the light is back on again. Code is P0133 - heated oxygen sensor, bank 1 sensor 1, circuit slow response.
Now, the dealership is suggesting I need to replace the catalytic converter with a Subaru converter before they can source the issue.
