My 2000 Nissan Maxima has a PO430 code for the catalytic converter that has been going on and off for over 1 year now. My ? is, how would I know that the converter needs replacing? Someone said there wouldn't be any smell necessarily, someone else said I would be leaking qts. of oil in between changes and someone else said it would get bad mileage. Each one debunks the others comments etc. Also just for info., this car had the ses light come on at 57K miles, my brother replaced 2 of the O2 sensors and I replaced 2 also, one duplicate one and a mass air flow as well.

A week ago I was traveling in my wife's 2009 RX350 at freeways speeds and outside ambient temperatures around 80 degrees. After traveling about 2 hours and stopping for about half-hour for lunch, I started the vehicle and went around a mile and the Check Engine light came on, the VSC was flashing and the traction control indicator was illuminated. I stopped quickly in a gas station and checked the manual for what the warning lights meant. Nothing of any value was found; I filled the car up and headed for home, about 4 more hours at highway speeds. The warning lights stayed on and the VSC flashed the entire way home. The vehicle ran perfectly with no problems at all.
The next morning I started the car and the lights were out. Still worried, I purchased an OBD2 scanner and pulled a P0015 code, Camshaft Position - Timing Over-Retarded (Bank 1). I erased the code and the car has been fine ever since. Finally to the question, is this something I need to worry about? I travel this trip about once a month and don't want to get stranded along the road. The car has 54K on it and if it is a sensor in the engine, it should be covered by the powertrain warranty, but more importantly, will it cause damage to the engine? I read that the camshaft position sensor would only be replaced under warranty if it was inspected and causing a loud ticking noise, which I do not hear. If it throws the same error code again, I will take it in to the dealer and let them look into it.
Lexus RX 2004-09 :: Low Oil Pressure Warning Light Blinking Then Stays On - Error Code P0346
I have a Low Oil Pressure warning light on. When it first came on, I stopped and check the oil level. It was low. I had to replace the oil 2 or 3 months ago, but then I had na accident (rollover) and just this past week i received the car and forgot to replace the oil. So that's what i did. Replaced the oil and filter.
The lights still comes on after driving about 3 or 4 miles. It starts by coming On and OFF a few times. Sometimes just blinking, than it stays ON until I shut of the engine. What it could be?
After the referred rollover, the engine shut off, but I turned it on less than 30 seconds after this (I know I shouldn't have done that) and drove for about a mile. Do you know if that would damage the engine or oil pump in 132,000 miles RX330?
I checked and found this error code P0346 (Camshaft position sensor). Would it be related?
Celica :: 2001 GT - CEL Came On / Code Read PO420
I have a 2001 Celica GT and the CEL just came on. Went to Autozone and had the code read (PO420) - they said it could be O2 sensor or bad catalytic converter. Is there any way to narrow it down before I just start buying parts to replace? Car has 140,000+ and runs great...surprisingly one of the few that doesn't seem to burn oil! PO420 diagnosis?

I own a 2003 VW Jetta GLS 2.0L 4 Cylinder and my CEL recently came on throwing the PO420 code (Catalyst System Efficiency Below Threshold (Bank 1)). So I replaced both the upstream and downstream O2 sensors. Well just one day after replacing the sensors the CEL came back on with the same code. I was wondering weather or not I should replace the whole catalytic converter or if there was anything else I should try. The car runs fine, exactly how it did when I bought it.
View 22 RepliesSubaru - Forester :: Shuddering During Acceleration - PO420 Code
I 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?
Subaru - Outback :: Intermittent Check Engine / Code PO420 - Catalyst System Efficiency
My 2004 Outback now has 120K, has always been maintained and repaired at the dealership (except tires and battery), and has always run great! I've had the plastick-y parts replaced over the last few years including head gaskets when one cracked and made smoke. In July I got a jump from a AAA tow truck, who said my battery tested as needing replacement.
In September my check engine light went on, and the dealer found the code PO420-catalyst system efficiency. They didn't seem to look any further into causes. The cat converter replacement was to cost $2521. They reportedly tested the battery as OK as part of their routine checkup. I declined the new cat converter till learning more. Meanwhile, my check engine light seemed to cycle on, then off, then on, then off . . . every several days.
In December I had the battery checked at Sears, who replaced it under warranty. So I guess it wasn't okay after all. After that my check engine light stayed off for somewhat longer than usual, then back on for most of January. I was just about to give in and get the repair done when it cycled off briefly a few days ago.
I've lost trust in the dealership because of their battery check which differed from others before and after theirs; and for their lack of specific diagnostics. The light is back on and I don't know what to do next.
Avalon 2005-12 :: CEL Error Code P0440 Error Code / Charcoal Canister Replacement
So 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 own a 2004 lexus gx 470 and I am having some audio issues. The stereo system is the standard Mark Levinson speaker system. When i turn on my car, I can cycle through the different radio stations and cds, but there is no receiving audio coming from the speakers. I think it may be an amplifier problem, but i also don't know where to locate the amp or how to get my radio to work again. Also, I have tried holding the audio button while cycling my taillights on and off 3 times, but nothing shows up on the screen. My radio has not been working for about a year now.
