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.
View 2 RepliesI have a 2011 toyota camry. 3.5L v6. I have code p0157. I know my car has 4 o2 sensors, but I am not sure which one to buy. Where this o2 sensor is located, and which one to purchase. A part number would be very useful.
View 3 RepliesMy CEL came on and is throwing code P0430. Is it just an o2 sensor? if so which one primary or secondary?
View 2 RepliesI have this code on my gmc serria 6.0L. I have changed the O2sensor2 but the code comes and goes. Less frequent than before I changed it. I am wondering if the cataletic converter can be altered and remove the code. I/e drill it out, take it out?
View 1 Replieswent to have an oil change. Standard procedure. Wife drives the 330 away and the check engine and VSC lights come on. I figure it's the maintenance indicator needing reset, but no..... the reset didn't work. Went back to my local mechanic who changed the oil to run codes and see what the problem is. Code P0157 = bad O2 sensor.
Now, I questioned him as to why these lights would come on DIRECTLY after they changed my oil. Is there any correlation there? NO, he says. No reason why these lights would come on immediately after the oil change and we've never seen these two lights come on at the same time before.
I've read every post and thread I can, but it seems like every issue is different. Some times it's a loose gas cap or gas cap that needs replacing. I have to drive 60 miles to the dealer some time soon to have a recall performed, but until then should I worry about this O2 sensor and these lights staying on?
2 weeks ago a check engine light came on with P0351-Ignition Coil "A" Primary/Secondary Circuit Malfunction, took the car to Toyota dealer and replaced ignition coil for cylinder No1. I drove the car for about 10K and check engine light came on again with P0606-PCM Processor Fault.
For the past week I was monitoring the DTC's using INNOVA- CanOBD2 Code Reader 3030 (ordered ODB2 USB tool to check live data on a laptop, on it's way...). I had P0606 on all the time, about everyday. For 3 times I had P0157-O2 Sensor Circuit Low Voltage (Bank #2 Sensor #2) on.
What's the link between the two DTC's? Why not P0157 alone? Or P0606 alone? What is the procedure to diagnose this?
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 RepliesI 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...
View 11 RepliesI 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).
View 1 RepliesJust 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.
View 3 Replies05 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.
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.
It came on 2-3 miles after a cold start. 3.6 with 137,000 miles. What's next? First car I've owned that uses very little oil between oil changes.
View 1 RepliesI have an '04 F150 with a P0430 code. Not sure where to start, I have read that it could be numerous things so I thought I should start knocking them off the list one at a time. Thought I would start with the cats. 2004 F150, 4x4, 5.4L, 126,000 miles ...
View 6 RepliesI USED to have an auto 2002 Camry XLE V6 with 151,000 miles. I sold it to my sister in law who needs a car. But the night before I sold it, I had cleaned out the throttle body with carb cleaner. The next day she mentioned that she needed a car and since I have a spare, she want to buy my car. So i sold it to her cheap ($2500)since she is family. A day later while putting 50 miles after the cleaning TB, she reported to me that the CEL is on. So I went and scanned it and got a P0430.
Last year I had replaced all A/F sensor and O2 sensor so I know that it's not the problem. Could it be that the carb cleaner damaged the cat or cause the A/F sensor or O2 sensor to miss read?
I reset the CEL and told her to report back if anything happen. I just feel guilty and ashame after the CEL...The car ran fine for me while owning it for 7 years until I decided to clean out the TB.
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?
[URL] ..... I had the P0430 code come up in my 06 GS300 AWD so i changed both passenger side 02 sensors. i followed the above instructions on changing the pre-cat sensor, changed my 02 sensor plugged everything back up and the P/S light came on and i lost power steering. I unplugged and checked everything at least 10 times until i finally gave up and gave it to lexus today. been about a week though driving without power steering. I know I did everything right and plugged everything snug. Did my P/S just decide to die?
View 6 RepliesReplaced 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..
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...
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.
I have a code that just started popping up on my 2000 Yukon XL2500 with 93K. I know I have a spot on the side of the Muffler that was rotted out and patched by the previous owner. My question is would an exhaust leak that far back in the system throw off the O2 Sensor?
