I replaced my oxygen sensors this week. My car has 230,000 miles and the previous owner never replaced them. Turns out, they were both broken and for God knows how long. My car began running rough and backfiring, and once at a stop, would not move an inch, but idled perfectly fine. My guess, carbon built up everywhere it could and now I'm replacing just about everything I can think of. I got underneath my car and tried like hell to break them loose with no success. Breaker bars, O2 sensor kit from autozone, no dice. So I went to my neighborhood mechanic just to have the bolts loosened and it set me back $35. Took her back home and replaced the oxygen sensors ($20 each). Don't forget! There are two different types of o2 sensors, the Upstream O2 sensor (before catalytic converter) and downstream O2 sensor (behind the catalytic converter). You can't use the same oxygen sensor for both positions. Also, don't forget to reset your car's computer after changing dirty or broken sensors, especially if your CEL came on. If you're catalytic converter is toast and you have a cheap car in an area with no emissions tests, you can buy an O2 sensor adapter that will "trick" your computer into thinking the catalytic converter is there and fine. They sell these adapters on walmart. com for 10 bucks, and with great reviews. Anyway, I've done a ton of work to my car in the past couple weeks, trying to get to the root of my intermittent mechanical issue, and keeping my fingers crossed that I fixed her. Tomorrow I'm resetting her computer and taking her out for the big drive. Wish me luck! :)

great , informative video , I wonder if you come across this strange problem engine 651 2.1 L (P02A7=cylinder4 fuel trim at min ) from the code you would think injector problem but sadly that was not the case , I swapped inj4 with inj1 and still the same problem P02A7 , went toward vacuum and checked all vacuum parts (intake manifold /vacuum resonator/turbo actuator/transducers/vacuum hoses) with no sign of vacuum leaks at all , in fact the system holding 15inch vacuum with no problem at a all , in regards to injectors tested with injector leak test all four injectors are leaking the same amount of fuel so I can't fault them , engine idling is fine / drive fine the only thing is if you cleared that code , you will get the full power of the engine I mean the turbo will be working as it should be until you drive in steady speed like 65miles/hour for 10 to 15 minutes as soon as you take your foot off gas pedal the check light will be trigrad and you will start loosing power specially up hill , the only suspect left for me is o2 sensor , I haven't replaced it yet , but when I disconnected no check engine light show up as if its connected , but am thinking that could be the o2 sensor is faulty thats why when the engine on that steady speed and by the time I let off the gas pedal , the ECU request the oxygen from the o2 sensor and most likely the wrong values from the o2 sensor is the suspect what do you think ? your help is appreciated

If the P0137 code continues to come up even after replacing the Bank 1 Sensor 2 O2 sensor, then there may be a problem with the wiring or circuitry that connects the sensor to the engine control module. This could be due to a damaged or corroded connector or wiring harness. It is also possible that the catalytic converter replacement was not done properly and is not functioning as it should. A poorly functioning catalytic converter can cause the O2 sensors to report incorrect readings, leading to issues such as decreased fuel efficiency and engine performance.

Have you checked for some kind of leak? Maybe you can get a large card board, split it from the center to get two then cardboard and place under car and monitor it like that. Maybe it’s dripping out. If not, try monitoring the rpm. Do you notice if it has higher than usual rpm, either when idling or when you’re driving. A next thing it could be, if no code is showing up, is maybe the car has and Over Drive available, you have it activated. Essentially, it keeps the car running in the smaller gears, so if you’re on a highway or long free roads, it’s using gas pointlessly. You’d mainly use it if you need some power and not speed. You’d maybe use it to climb up a somewhat steep incline. Or maybe you’re trying to help pull a car out from a ditch. You can do a little research on if your car has OD and how to enable and disable it. I remember I drove my cousin’s Tacoma, Dont recall year, but it’s not a recent model, and the OD button was on the shifter. I accidentally pressed it and was wondering why it was driving funny.

The contact point of one of the 4 contact points inside the sensor connector is broken. And I’m having issues with Mpg efficiency too. I figured maybe the bank 2 sensor 2 is the one that helps monitor and controls the air/fuel mixture. If it doesn’t get feedback, it just keeps throwing in more fuel than it needs. God having a car is a pain. What’s worse, it’s difficult to fucking unscrew this shit.

How did you come up with a an airflow sensor with for a bank one lean condition? That might be the problem, but an 0172 is a generic code, which means there are many things that could turn it on. When you see a bunch of lights come on for systems that are primarily safety features, its considered normal. For example, if you have an issue with your ABS system, your vehicle will automatically shut down other systems like, traction control, parking assist, adaptive cruise control, lane drift condition, etc. All of those systems won't work without ABS, so they all get shut down as a precaution.

You have to diagnose the problem, not just replace parts until you guess correctly. Your O2 sensors can't cause a hard start condition because they don't work when they're cold. Your PCM ignores them and they only come online when they reach a specific operating temperature. About 600 degrees. You have to look somewhere else.

Yes, a bad O2 (oxygen) sensor can potentially cause your car to vibrate when you drive off from a complete stop. If the O2 sensor is malfunctioning or sending incorrect readings to the ECU, it can disrupt the engine's fuel management system. This can lead to an imbalance in the air-fuel mixture, resulting in poor engine performance, rough idling, and potentially vibrations during acceleration.

Thats certainly interesting. Most likely will be the O2 sensor, due to the age of the vehicle or perhaps the Oxygen intake is struggling to meet the demand of Fuel injected with the new modifications. My vehicle (Manual VW Jetta 04) would stall at idle or if the revolutions in the engine became too low at neutral, it would stall. I replaced my air vacuum tubes (cracked and broken) and got the true cold air intake installed correctly because the previous owner didn’t attach it properly. My engine stopped stalling afterwards and I hadn’t had the problem since, however the code appears every once in a while despite it running decently. My vehicle went from 18 mpg to 27 after that fix, however I believe that my O2 sensor is bad or I need to replace a faulty fuel injector.

@052RC12 күн бұрын
If you are going to modify your vehicle, you should know what you're doing. Mods bring your sensor data out of spec, and unless you know how to compensate for the changes, you'll have problems. O2 sensors can't cause a hard start for one simple reason. O2 sensors only work when they're hot. (aprox. 600 degrees). Before they reach operating temp, they give bad readings. Because of this, you would get a check engine light every time you start the car with a cold motor. To deal with this, your pcm has 2 modes of operation. Open and closed loop. When you first start the car, the pcm defaults to open loop, and stays in open loop until your O2 sensors reach a minimum temperature. The important thing to remember, is when your vehicle is running in open loop, it disregards the reading it gets from the O2 sensors, and runs under an alternate fuel injection mapping strategy while everything is warming up. Simply put, your O2 sensors can't cause a hard start because they're ignored whenever you are in open loop.

It's worth noting that even if you don't have catalytic converters installed in your vehicle, you still have oxygen sensors that monitor the engine's air-fuel ratio. The sensors are located before and after the catalytic converters in most vehicles, but in your case, they would be located upstream and downstream of the secondary air injection system. Firstly, you can use a scan tool to read any diagnostic trouble codes. If the O2 sensor is malfunctioning, you may see a code related to the sensor or the engine's air-fuel ratio. If there are no codes present, you can use a multimeter to test the oxygen sensor's electrical resistance and voltage output. The resistance should be within a certain range, depending on the sensor's specifications, and the voltage should fluctuate between 0.1 and 0.9 volts when the engine is running.

Yes, a bad O2 sensor can cause a failed emissions test even if the check engine light is not on and there are no error codes stored in the engine control module. If the O2 sensor is faulty, it may not be able to accurately measure the oxygen levels in the exhaust gases, which can result in increased emissions. This could cause the vehicle to fail an emissions test, even if there are no other apparent issues.

It sounds like you have been through a lot with your car, and it's frustrating when replacing parts doesn't solve the problem. Based on your description, it's possible that the oxygen sensors could be the issue, as they can affect the performance of the catalytic converters. However, it's also concerning that your engine is losing compression and that the car is rattling and shaking. It's important to have a qualified mechanic take a look at your car to properly diagnose the issue and prevent any further damage to your vehicle. They can perform a compression test to determine if your engine has lost compression, and check the oxygen sensors and other components to identify any other potential issues.

Given the combination of codes and the fact that your vehicle starts but turns off after a few seconds, it's possible that you're dealing with multiple issues. Here are a few steps you can take to troubleshoot the problem: 1. Inspect the wiring and connectors related to the oxygen sensors, throttle body, and idle air control valve. Look for any signs of damage or loose connections. 2. Clean the throttle body. A dirty throttle body can cause idle and stalling issues. Remove the intake hose and clean the throttle body using a throttle body cleaner. 3. Inspect the spark plugs for any signs of wear or fouling. Consider replacing them if needed. Additionally, check the ignition coil for cylinder 1 and ensure it's functioning properly. 4. Test the oxygen sensors. If the wiring appears to be in good condition, it's possible that one or more of the oxygen sensors are faulty. Consider having them tested or replaced.

Rough idle plus loss of power. Definitely an oxygen sensor fault. Cleaned it and I will give you an update if it works
@Oatis_07 Жыл бұрын
I’m getting Error Code P2198 & I think it’s the Oxygen sensor on bank 2 sensor 1 because I have a rough idle, it turns off at random & even when i start it sometimes it just dies out, then it smells al lot like fuel & you also feel some vibrations on the car so that’s why I think it’s the Oxygen Sensor but what do y’all think?
@carproblemsmax Жыл бұрын
Based on the symptoms you have described, it is possible that the oxygen sensor on bank 2 sensor 1 is faulty and needs to be replaced. If the sensor is faulty, it can cause a rough idle, stalling, and a rich fuel smell.

Hello, Maybe you can help me with a question. The apologies of the case for my English, it is not my native language. I have a motorcycle and since it is already hot and idling the scanner shows a voltage in the oxygen sensor (it is a single wire) of between .8 and .9 which drops to between .1 and .5 when the motorcycle accelerated it also marks the change from open loop in idling to closed loop in acceleration. Is this normal?
@macoyskietv7784 Жыл бұрын
Is your issue resolved bro ?
@052RC12 күн бұрын
It depends. In a car OBD2 laws requires all manufacturers to comply with a specific set of regulations. Wide open throttle on an obd2 vehicle forces an open loop condition. I don't know what the standards are for motorcycles, but if its going into open loop all the time, and not just under WOT, you probably have an issue.

Boss how can i solve P0420 in Toyota Prius C
@carproblemsmax Жыл бұрын
The P0420 code in a Toyota Prius C indicates an issue with the catalytic converter: Check for any exhaust leaks. Exhaust leaks before the catalytic converter can cause false readings, triggering the P0420 code. Inspect the exhaust system for leaks, and repair or replace any damaged components. Replace the oxygen sensor. A faulty oxygen sensor can cause the P0420 code. Replace the sensor with a new one. Check the wiring for the oxygen sensor and catalytic converter. Damaged wires can cause issues with the catalytic converter system, resulting in the P0420 code. If none of the above steps solve the problem, the catalytic converter may be damaged and needs to be replaced. Note that the P0420 code can also be triggered by other factors, such as engine misfires or fuel system issues. If the above steps do not solve the problem, it's recommended to take the vehicle to a certified mechanic for a more thorough diagnosis.

Is it true that o2 sensors have an expiration time frame? My mechanic thinks it needs a replacing since I keep getting P0420/P0430 every 6 months after using catalyst cleaner. What are your thoughts? @@carproblemsmax
