Lexus SC430 :: New Oxygen Sensor Reading Zero Voltage - Code P0430
Replaced my post cat drivers side O2 sensor tonight because I was getting zero voltage and a p0430 code. This is bank 2 sensor 1.
But I'm still reading zero voltage!! How could I still be getting zero voltage?? I checked the connections and they are firm. Checked every single fuse in car.
After my recent accident, the center console lights don't illuminate. My nav door doesn't close too. Could these all be related?? The connector for the O2 sensor is right next to the console, so maybe there is a loose connection or plug or perhaps a stray ground?? I do have wires all over the place in under the shifter bezel from aftermarket stuff..
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?

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.

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.
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.
Lexus GS 2006-11 :: GS450h - P0430 Catalyst System Efficiency Below Threshold Bank 2
Have the EML on on my GS450h, read the fault codes and I have 2 fault codes that are identical (P0430). I cleared the fault codes and it stays off for a day, then as soon as I go above 60mph the next day, it comes back on again, the faults are stored and not current codes. I've not noticed any MPG loss or loss of power whatsoever! So am I safe to assume its not the catalysts? Only other thing I could think of is an o2 sensor gone bad perhaps? I don't want to spend money really as I'm about to sell the car for a more economical one for my 150miles per day commute to work! Just had all 4 wheels refurbished too which set me back a fair amount, now this!

I just purchased a 2006 GS300 AWD w/115k. Started car on lunch hour to find check engine / check VSC lights on. Ran codes to find P0333 Knock Sensor code. Vehicle seem to run perfectly fine, but now that the light is on, it is definity spark knocking under acceleration. This is my first Lexus / Toyota product, so I am unfamiliar with the common problems or fixes. Are knock sensor replacements common?

Accent LC (2000-05) :: Code P0335 / Replaced Crank Sensor / Still No Spark
Like the title says...'02 Accent,1.6 dohc.Won't start.No spark.
Pulled code p0335-crank sensor circuit A.
Replaced sensor...still nothing.
Is there something else that commonly goes with these symptoms?...or did I just get a bum sensor?
Also,once I try starting or turn key on,I hear a buzzing coming from throttle body area for about 10 seconds even after key is off. Not sure if its related or normal.
Civic - Honda :: 2004 - CEL Came On Again With Code P0134 / Replaced Wrong O2 Sensor?
2004 Honda Civic with 166000 miles.
--Had Check Engine light on for a couple days and code reader said P0135. Parts guy said this means "Bank 1", my Haynes book calls this code for " Primary Sensor 1" Is this the same as "Upstream"?
--Replaced O2 sensor (Denso 192400-1160 05F12) myself with a new one (Bosch 15710). Fit perfectly, plugged right in.
--Check engine light goes off for about 5 minutes but comes back on with code P0134.
What should I do now? I replaced the sensor closer to the engine before the catalytic converter. Very easy to reach from the top. I rented the correct tools and did not damage or force anything. Is there a second O2 sensor after the cat that is not so easy to reach? Was that the one I needed to replace? Did I misunderstand the meaning of "upstream" or "Bank 1"?
Sonata NF (2006-10) :: Intermittent Rough Idle Caused By Power Steering Sensor Switch
I've been experiencing an annoying intermittent condition on my '07 Sonata (Lambda V6). I wanted to share this in case any of you are experiencing intermittent rough idle complaints in your Sonata (4G) as well. I was finally able to get it into the dealership during the malfunction; in my case, the MIL never lit. Here are the symptoms: ONLY after being fully warmed up, when coming to a full stop, or using just idle speed to, for example, pull into a parking space, or inch up to a stoplight, I would experience a very rough idle (I could hear the engine sputtering with the window down), see the RPM gauge bouncing, and feel the vehicle going "putt-putt-putt" as it tried to keep running under what seemed to be a misfire or too much load. The problem occurred more noticeably with the A/C off but still did occur with it on as well. While exhibiting this problem, acceleration from a stop gave a slight hesitation as well, but once going faster than 1,000RPMs, the problem went away totally. I thought it must have been my imagination until one day, I pulled up in front of a glass window and could see the reflection of my car lurching forward as it struggled to keep idling. Getting it to the dealership while it was behaving badly was the hardest part.
Once I got there, I got a tech to ride with me and finally, after 3 visits to the dealership, someone else witnessed the problem. Up until now, I've been asking people, "Do you feel/hear that?" "Huh?" I digress... The tech immediately said he thought it was a power steering issue and he thought there was an upcoming bulletin on it. I was sure he was wrong, I was thinking it had to be the spark plugs, wires, MAF, or TPS.
After getting the part in for me (Power Steering Sensor Switch) they put it in today and my vehicle is just as new again. It was never a serious issue, but was rather embarrassing to try and show off my Sonata and have it stutter and sputter like that it idle.
This part is complete speculation; maybe a more knowledgeable person can jump in here and correct any logical errors: Apparently, there is a switch in the Power Steering Unit that detects highway speeds versus slower speeds. When vehicle speed is above a certain limit, the power steering pump is either turned off or "turned way down" (so people get the stiffer feel of the wheel at highway speeds). When the vehicle slows down to idle (to be detected by this switch), the vehicle expects the power steering pump will draw full power from the engine and needs to have a slightly higher idle speed to compensate for the load. My switch was malfunctioning; it was not registering to the ECM that the power steering pump was under load when it actually was; the vehicle then did not bump up the idle speed appropriately, and thus, the rough idle and hesitation.
Golf IV / Jetta IV :: Code 00281 - Replaced G68 Sensor But Still Only First Gear And Reverse Are Functional
I started my car the other day and found that it only drives the first gear and I can also put it in reverse. VCDS gave me a 00281 code saying no signal from Vehicle Speed Sensor G68. I replaced the sensor, but it still doesn't go into gear beyond 1st.
VCDS gives me the following codes after replacing G68.
2 Faults Found:
00652 - Gear Monitoring
27-10 - Implausible Signal - Intermittent
00281 - Vehicle Speed Sensor (G68)
03-00 - No Signal
I came across TSB 01-99-02 which says something about the codes being incorrect. It seemed a little vague about whether it is actually G38 or G22. I don't want to buy more sensors only to have it be something else. The speedometer and tach work fine so G22 doesn't seem likely to me.
The VCDS site says it could be several things including bad G68 or G38 sensor, low fluid & bad valve body. Was it the G38 sensor?

I am running a 2008 Ford F-250 with the DPF Delete and the Mini Maxx Tunner. I have replaced the ECT (Engine Coolant Temp Sensor) as well as the EGR Valve and housing troubleshooting this issue. Both the Engine light and the coolant icon come on when I turn on the vehicle. I am getting a P0117 Engine Coolant Temperature Circuit Low code on the Mini Maxx.
From a cold start with codes cleared if I turn the engine to ON even without starting the engine the Engine codes will come on and the the Mini Maxx will read engine coolant temp 302 and will go into Defueling Mode. I have repeatedly tried removing and reattaching the connector to the ECT thinking it could be loose connection. I can't drive the truck because there is no power and i know the engine is not hot because I have let it sit all night before doing these tests. I do not have a scanner to test other than the Mini Maxx. Other notes: I have checked Coolant I have checked Oil
Ford Super Duty (1999-2016) :: 2011 F350 6.2L - Got Codes P0420 And P0430 Even Replaced Catalytic Converters?
I bought this truck (2011 F-350 6.2l) used a month ago with 125000 miles on it. Of course the MIL light came on as soon as the ink dried. The codes read PO420 & PO430 and my local Ford Service said replace the cats. I said what is the cause of the failure, ford said here is a list of possible causes but it's not reading other codes so they don't know what caused the failure.
Well, I went ahead and replaced both catalytic converters, all four O2 sensors, and I replaced all sixteen spark plugs. Guess what, the MIL light is back on not 24 hours later reading PO420, PO430, and now PO620 and PO645. So I just went back to Ford today and all they did was cleared the codes and told me to call if the light comes back on. They said my PCM is up to date but why it's now reading GENCOM code or AC Clutch code.
