Got P0463 today. Guy at garage told that my first step should be to replace a gas cap. I did this, and it doesn't help. Check engine light lits, and fuel level gauge on dashbords is going crazy. What to do with it?
Can I replace bad parts by myself? Dealer wants $500 for parts and labor.
Thanks!

Purpose: Did your Scooby throw a cel?

Help us to see what is common with subarus, every car line has problems accross the line, with the thread we can see what kind of problems subaru is experiencing, what are the most common causes of the CEL to come on on a scoobie.

So please post, your cars, year, make, model and mileage, what cel code you have gotton, the code and definition.

If it was fixed, please include what was done to rectify the the problem.

Things not to post.
If you have a high flow cat and keep getting cat efficiency codes.

this is a reference thread meant to help those who have from stock to slightly moddified vehicles.

lets see how it goes.

Thanks everyone.

Please try to use this format for posting to the log, then add your comments below the entry.

Code: Defintion
Year/Make/Model
Mileage:
Fix for problem:

Code: P1016
Year/Make/Model: 1998 Subaru Impreza 2.5RS
Mileage: 92500 when bought, now 95600

i bought the car with a catback stromung exhaust, and the guy said he'll paint the engine bay for me, but he never did and he said he took it through the car wash and then the CEL came on after he came out of the car wash, and car seems to run okay, just that it's making a ticking/rattling/paper flapping noise, it's like coming from the valves on the side with the battery

i'm taking the car in for another scan tomorrow to see if there are any other problems, the car already had an emission test so i'll have to wait till next may/april

Code: Flashing CEL flashes at 5 cycles/second. The following codes were generated and cleared and have not come back, but the CEL still flashes all the time.
0130 (02 Sensor Circuit Malfunction (Bank I Sensor 1))
0136 (02 Sensor Circuit Malfunction (Bank I Sensor 2))
0500 (Vehicle Speed Sensor Malfunction)
1101 (Neutral Position Switch Circuit Malfunction (M/T))
Year/Make/Model: 1996 Subaru Legacy Outback wagon- EJ22/2.2L H4 engine
Mileage: ~184200
Fix for problem: "Problem existed between seat and steering wheel". There are two little green plugs under the dash that aren't meant to be connected to each other. Connecting them puts the car into a debug mode of sorts which is characterized by a flashing CEL. Issue gone.
Extra notes - posted a big thread in Electrical and Lighting titled '96 OB Wagon Amp Install -> Flashing CEL, basically I did an amp install and got the above CEL codes. The car runs fine with no noticable problems for 1200 or so miles since the CEL showed up.

Code P1133, Front AF Sensor Heater
Car: 2000 Impreza OBS, EJ22, 4EAT
40K miles
No particular symptoms except for vauge loss of power, no noticeable misfire, poor fuel mileage (22.4)
Light came on and would not clear with diagnostic tool.
Fixed by replacing front O2 sensor with Denso part 234-9018
Purchased from Sparkplugs.com for $99.71 + shipping
After repair light went out by itself after about 5 miles of normal driving.
Engine power and response improved a lot. Car just feels happy now and got 24.5 mpg on first tankful after repair.

Fix for problem: None yet
No Modifications

The car was purchased car over the weekend in California and the CEL was triggered at some point in the 950 plus mile drive back to Seattle. Performance of the car was not noticed to be negatively affected, just the drivers confidence/happiness with the purchase of the car. It seems to run great. I cleared the codes last night and managed to come up with another code (hasn't been pulled yet) 25 miles later, I am forced to assume it is the same. I will hit up the Autozone tonight and run the diagnostic again as well as aquire a set of plugs to be installed later in the day. In the meantime, any suggestions/tips would be appreciated. I am entirely new to this marque and Japanese cars in general. Thanks.

A P0420 on a stock car usually means the cat is shot (after all, that is what this code is actually for). Subaru should replace the cat under the 8 yr./ 80K emission warranty.

Code: P1088 Tumble valve position sensor circuit low.
Year/Make/Model 2004 Subaru Impreza WRX
Mileage: 33000
Fix for problem: After verifying that the circut was not shorted, or grounded I i jumpered the connector on the sensor with a 1 Meg. Resistor. Red to White/Red For the Right Hand side the sensor connector wire colors are Red(5v), White/Red(ECU), and Black/Green(Com.). It cannot be purchased separately it comes as a unit for about $380.00. That is why i used the resistor, the unit needs replaced. Since i have modifications two dealers in my area have chosen not to service it as a warranty item. I did not push it since it quit working after i changed the turbo inlet hose. I got the cel after i installed the hose. I really dont see how changing a silicon hose killed the sensor but it is close to the turbo inlet.

I completed changing out the OEM Platinum plugs to V-power copper plugs from the same manufacturer last night. I thought I was gonnna be sitting pretty, staring at an unlit CEL, but it came back after about 30 miles. My car has about 50k (right around their first scheduled change apparently) on it and the old plugs looked very original and very used up...Damn. I can't say the car runs any better, it still feels just as great as it did with the old plugs. If anyone could provide me some ideas as where to head next to remedy my cars misfiring, I would really appreciate it.

I just returned from the dealership where I was told that I had to bring the car to them to permanentally turn off the CEL. Apparently you must have the machine connected to an OBD II computer to turn it off rather than disconnecting the battery. Is there any truth to this or was the guy just trying to deprive me of $50?

Either way will turn off the light but neither is permanent if you don't actually fix the underlying problem that set the code in the first place. Unless it was a one-time occurrence the light will come back when the code re-sets.

Okay. Thanks for that. He said that disconnecting the battery just wouldn't cut it. I am just gonna try and fix one thing at a time and clear the codes as I go. I guess I will measure resistance over coil packs next.

Dammit, I guess I thought I knew how to do this. Is there an approved method for testing the coils in this car?

If you are getting misfires on all cylinders it's unlikely to be from bad coils. Usually a single coil pack will fail causing misfires on that cylinder only, it's very doubtful that all four are bad at the same time.
Possible causes of all-cylinder misfire codes are bad gas, loose or defective cam or crank position sensors, vacuum leak. Also spark plugs but you did change those. Are the new plugs gapped properly, and are they the proper ones for the car? You might try a set of the OEM NGK platinums to fully eliminate plugs as a cause.
Lightened flywheels can also do this in the WRX, especially in combination with a lightened pulley. Are you sure the car does not have any mods?

The sensitivity of this cars on board diagnostic system must be quite favorable to Subaru's service department. I was kinda thinking the same thing on the coils but so many people seem to mention to turn to those next I fell in. I have never, in my whole life seen a dead coil; but then again, this is the first non-British car I have ever owned. Is there a diagnostic method for the cam sensor, or should I just throw a part at my car? As a side note, my light went off today. I felt absolutely wonderful as it has been a very trying day. Then it went back on again. I will have to assume that it is the engine misfire until I can go and scan it. I guess I was under the impression that these did not turn off once they had developed. Any comments?

Any ideas? It is not the MAF sensor itself... I tried putting a new MAF sensor in and that wasn't the fix. The car will not run with the CEL off. If you clear it with the car running, it shuts off and sets the CEL.

Default Don't connect two green wires under dash!

I was replacing the white plug that goes at the top of the clutch pedal to depress a plunger switch to signal the cruise control that the clutch was out and I must have accidentally caused the two green wires to make contact. The check engine light came on and my repair guy got all kinds of weird codes until he found the wires touching and disconnected them.

Apparently they had some diagnostic use in earlier models but not now. They are like an appendix - no useful purpose. Keep them disconnected.

Code: P0141: O2 sensor heater circuit malfunction (bank 1 sensor 2)
What :1995 Legacy
Mileage: 171,000
Fix for problem: none yet
Modifications: none

Autozone cleared the code but the light came back on after a few on/off cycles. The odd thing is I replaced the O2 sensor fairly recently (2 yrs ago but only a few thousand miles; the car does not get driven much). The car seems to run fine. Does it need a new O2 sensor? Should I even bother changing it if it runs OK? It will probably be heading out to pasture before its next inspection comes up.

Change it if you want. The car has detected that the heater circuit is bad in the sensor or the sensing equipment is bad. The heater just makes your O2 sensor get up to operating temperature through resistive heating of the element. If the ECU thinks that it is getting good data from the sensor and it just has a bad heat up circuit, you really aren't in for that much trouble.

Personally, I would change it.

CEL came on and has been on / off every 3 days or so for the last 10 days. Dealer pulled the above mentioned code. It's not a super-expensive part to replace, but I'm not sure it's required at this point. Can someone give me a quick explanation on where to look for the knock sensor? I'd like to pull it out and clean the connectors etc.
