Lexus RX 2004-09 :: Code P0430 With CEL, VSC Went On
My car is running great, no issues. I just changed the ignition coils, i was having a misfire. It was easier since i was changing the back to replace them all. My CEL and VSC went on and it is code P0430 bank 2. Before i spend a ton on a new catalytic converter i would like to change the o2 sensors. Problem is, I am not sure which ones to change or where to start. Is this even something i am able to do?
View 2 RepliesPassat (B5) :: 2001 - P0430 Code / Stutter And Misfire After Cold Start
2001 V6 Passat with 125k miles throwing a P0430 code.
Having trouble on cold starts, takes about 10 minutes to finally get it to turn over. When it does the idle is extremely rough. For the first 1/4 mile the car bucks, stutters, and misfires. After that it runs fine and starts fine when already warm. I am noticing slightly decreased gas mileage but nothing major.
Valve cover gaskets were replaced 2 months ago, but were leaking oil for at least a year before I could afford to have them replaced. I am still noticing some oil leakage, however not as much as before. I have had both O2 sensors replaced twice in the past 5 years. Timing belt was replaced at 98k. What might be causing the starting issues?
Lexus RX 2004-09 :: CEL / VSC And Trac Off Lights - Code P0430
SO all three lights came on and wouldn't go away.
Ran a scanner for code and got p0430.
Took it dealership for estimate or fix.
Go figure : code summary: Causes.
Reported fixes or Causes: for code p0430
- catalytic converter has failed.
- Air fuel ratio sensor
- Bank 2 cat converter
- Bank 2 (A/F) ratio sensor
- Oxygen 02 sensor
- downstream Oxygen 02 sensor
- Exhaust pipe
- Mass Air flow sensor
So I am waiting thinking ok let be one of the above causes or fixes that is cheap.
Ford F-150 (2004-2008) :: Very Loud Knocking Noise On Cold Start Up
5.4. So I have a 2004 F-150 that just passed 80,000 miles and a month ago it started making a very loud noise on startup, but only cold startup, meaning if I haven't used the truck in about three hours. Now I went on youtube to research and found a video of a truck making the exact same noise! Here is the link:

Need to verify what this is??? Some people are saying cam phasers and some are saying I'll need a brand new engine!
Lexus GX 2004-09 :: Long Term Fuel Trims Really High And P0430 Code
I got a P0430 code. My fuel trims are over 20% on both banks. A few days back I got a P0174 code but after disconnecting the battery it cleared and hasn't come back. Are these codes related in any way?
I'm a bit confused because I removed both cats and put O2 spacers in on both sides. I never get a P0420 code. Is one of the spacers not working correctly? I sent Toyota an email about the 430 code and they want to know which of the cats were removed - front or back. I didn't even there were front AND back ones! I thought there were just 2 side by side.
When I analyze the O2 readings on Torque they look pretty similar for both banks although I admit I'm not the best person to judge. Both rear O2 sensors are fairly new.
Unfortunately living in the middle of Africa I can't get hold of a smoke machine. I'd love to look for a vacuum leak, as from what I've read about the subject this might well be the cause of my problems.
One mechanic wants to put a new fuel pump in but I'd like to postpone that because it's a pricey item.
Ford F-150 (2004-2008) :: P1299 Code - Won't Start - Turn Over But Not Firing?
Just went out to start the truck (2006 4.2L) and no start...turns over but isn't firing.
I checked codes and got a P1299. She was stone cold and ran perfectly last night - never overheated.
I suspect ground or other wiring...where should I start?
Ford F-150 (2004-2008) :: Truck Stalled Out And Would Not Start - Code P0452
The other day my truck stalled out and wouldn't start so I had it towed to the shop, the shop tested the fuel pump but couldn't find anything and it fired up and ran fine for them. It ran fine for a day and now is running extremely rich. The only code it's throwing is P0452 which is for the evap system. I spent awhile searching but couldn't find any answer on it.
I couldn't find any loose connections in the harness or on top of the fuel tank, I had the classic FDPM issues before so I replaced that. I'm beyond frustrated with this hulk seems like once a month it wants to quit working.
Ford F-150 - 1997-2003 :: CEL Code P0430 Came Up After 10 Minutes Of Filling The Tank
1997 F150, 4.2L V6 200k miles. Truck has been running fine. No CEL, or anything. Stopped and filled up the tank and within 10 minutes of leaving the pump, the CEL came on. Code is P0430.
I drive this truck 60 miles a day. It's shown no signs of any issues until the light came on today. Just curious if some bad gas could cause this or am I in for CAT replacement...
Camry :: Code P0430, P0157 Came On
My 2009 Camry came down with the p0157 code which I looked up & is oxygen sensor circuit, low voltage bank 2 sensor 2. I'm trying to figure out which side this is(driver or passenger)? Also have a p0430 code-catalyst system efficiency below threshold.

My CEL came on and is throwing code P0430. Is it just an o2 sensor? if so which one primary or secondary?
View 2 RepliesInfiniti - G35 :: Fixing SES P0430 Code?
I recently purchased a used, high mileage 2004 Infiniti G35x (AWD) 145K miles from a reputable new car dealer here in my town. The car was impeccably maintained and clean inside and out. Just a week or two after the purchase my SES light came on revealing engine Code: P0430 (catalyst efficiency below threshold bank 2) pointing to a new catalytic converter in my future. Infiniti recommends premium unleaded for this vehicle. I found out my son filled her up with mid-grade unleaded. Is there any chance this could have triggered the SES light to come on? (Previous owner states he always used premium unleaded in the vehicle since ownership.) I also double checked the gas cap to make sure it was on tight. I find it extremely odd that the SES light would come on so shortly after the purchase. I mean what are the odds? Don't dealers run a diagnostic scan of their trade-ins to check history and for potential problems prior to selling their used cars? I test drove this car numerous times without any indication of a problem and right on the heels of the purchase it passed state emissions... now just a few days later, the SES light comes on. Why wouldn't emissions pick that up? I have reset the SES light (code) and filled her up with premium unleaded. Now it's a waiting game to see if the light comes on again. If the light reappears, I plan on taking it back to the dealer to work out some kind of "reasonable solution" to repair costs. I'll find out just how willing he is to stand behind his cars. I realize that this is a high mileage car, and I hardly expect perfection, but I didn't see this coming. What to do... what to do... By the way, I checked all the fluid levels ... no discoloration in the oil (fresh, golden brown)... no discoloration in the coolant... transmission fluid, good... all other levels are good. Car runs fine, no rough idle in cold...

2005 5.4L She would have a hard time starting before but after I replaced and fixed everything below she was running really good. Now back to sputtering, taking a long time to start and now not starting at all.
I have replaced; Fuel Pump, Fuel Filter, FPDM, Plugs and COP's, FRP Sensor, followed the power wire from the FDPM and found it corroded bad so I replaced it, also changed the ground location on the FDPM, I have checked all the wires from the FDPM to the drivers seat, checked all fuses.
I have power to FPDM and I have the diagram for the plug but how can I test (hotwire) the Fuel Pump without lowering the fuel tank? What should be the voltage coming from the FPDM plug? not sure about pin 1 & 6.
How can I test the FRP sensor? what are the specs for voltage?
Santa FE SM (2001-06) :: CEL Code P0430 Popped Up
I have a 2005 Santa Fe with the 2.7l engine....during the last two summers I've had this code pop up only to disappear. Well, we're into the winter here in New York and the code popped up again and after a week its still on. What's causing this and are there any easy fixes? The wife loves the SUV, its got 120,000 miles on her, the engine is strong and the tranny was rebuilt this summer (that another story).

Just read that a clogged EGR valve is common and reduced performance and increases emissions. Need to clean this valve? Where is it located?? Just noticed tonight that there is not a lot of suction from my vacuum lines and I wondered if this is related. Plus I have a p0430.

05 santa fe/3.5L/ owned since new. Had a misfire problem and solved that by changing coils/plugs/wires...
Still getting a P0430 code (bank 2 cat efficiency low)
Following the Repair manual troubleshooting of that code says
Read H02S - got a scan tool and did that -
Comparing Bank 1 H02S1 and 2 show they are are different voltages and do not follow.
Comparing Bank 2 H02S1 and 2 show nearly identical traces.
I also checked the wiring harness around the sensors and check for air leaks...couldn't hear/see/feel any.
My conclusion based on the info obtained is that the bank 2 cat is bad and needs to be replaced.

I have a 2004 F150 Lariat Supercrew 4x4 . I got a new transmission put in and a Oil change shortly after. A few weeks later I got a knocking noise. No check engine light, starts up great, No real notable problems just the noise. At Idle no noise just the usual cam phaser ticking, but once the engine is warmed up at about 1100 RPM it starts knocking like a . I took it to a few different shops one was sure it was the timing area so they replaced the timing chain, tensioner, pully. ect. Took it to a ford dealer where he didn't really look at it just said you need a new engine.
I went to another ford dealer where they said rod knock or stuck lifter but if that were the case shouldn't it knock constantly? another shop said VCT soleinods, Spark plugs. another said it could be the flex plate! I'm aware of the cam phaser diesel ticking noise they notoriously have but thats not it. I've parked it for a few years to be safe but started it weekly. I didn't intend on having it sit for so long but due to work situations and what not it has sat but now I'm on a mission to make it my daily driver again. I'm no mechanic but I'm not totally green to vehicle mechanics so ill be inspecting what i can within my limits.

Ford F-150 (2004-2008) :: 2005 - New Engine / Knocking Won't Go Away
I have an 05 f150 5.4 v8 super crew cab and I bought it for 3000 because of a cracked block. I bought a re-manufactured engine and installed it and now i have a knocking that wont go away. After I started it up it sounded beautiful for about 10 minutes and then i had a knocking start up. I have put about 30 miles on the new engine and still have the knocking. I let it sit over night and I started it up and there was no knocking so i drove about 3 miles to the gas station and by the time I got there the knocking was back. it runs fine no other issues but why do I have this knocking with a new engine.
