Can I still drive my car with a heated oxygen sensor?
Oxygen sensors in general are normally located before and/or after the catalytic converter. P0136 is a generic code for types of trouble with oxygen sensors on “Bank One” of an exhaust system (FYI, if you have true dual exhaust Bank One will be driver side). The code that you are receiving is more of an indicator of dirty or bad oxygen sensors. As oxygen sensors are installed directly into the exhaust pipe, normally somewhat near the engine. Point being, they are always what I would consider very “heated”.As with any check engine light it should never be ignored or driven any further than necessary. But to answer your question, if your vehicle will start and stay running, it is drivable. If your light has not been on for the past several months, ie. just came on within the past few days, you should be fine. Oxygen sensors can cause the vehicle to run extremely sluggish/rough and/or stall. As well as no run/start at all.If you do replace your oxygen sensors it would be wise to also replace your EGR valve as well as the PCV valve as these can potentially cause very similar problems (not to mention these are normally more inexpensive & easy to replace items that will help the vehicle run better & more efficiently).Average PCV Valve, less than $5.00. EGR normally $30.00 or so. But be advised that part prices can differ greatly from normal auto parts stores to online pricing. I just put a new EGR on my 2001 Chevy Silverado and local parts store pricing ranged from about $115 to $145. I purchased it online for $35.34 with shipping. You will find oxygen sensor pricing to probably be skewed about the same (I am not the biggest fan of ordering parts online but am forced to because of the dramatic cost differences).Good luck and I hope this helps you!
Can I run a car without an oxygen sensor?
Why would you remove the o2 sensor in the first place? Just leave it in. You can drive the car with a bad o2 sensor and it'll run fine but throw a trouble code and trip the Check Engine light. If you don't have a sensor at all, get one and put it in. They're cheap enough and easy enough to install.
Oxygen sensor keep burning out?
Your mechanics have NO automotive intuition. The REASON for your woes is a dirty THROTLE BODY and IAC valve. The IDLE AIR CONTROL valve fine tunes your air/fuel mixture. It TOTALLY affedts the O2 sensor and the converter. It gets signals from your computer and your O2 sensors to adjust air. LESSON::: your foot is not really the "GAS" pedal, it is the "AIR"pedal. Your foot only opens the throttle body door to allow more or less air into engine. Other sensors meter fuel through injectors. There is NO real connection between your foot and the gas. Using cheap engin eoil makes vapors tha clog up the T body and the IAC valve. Take $20 to the local quicky llube and have them wash out your T body and IAC valve. They can check the electrical harness to this valve. For BEST results, after the IAC is coleaned to SHOWROOM clean, remove stock plugs and install a set of Bosch Fusion or Bosch Iridium plugs. These fir fuel CHEMICALLY as well as just sparking off. More power and less carbon will be made. You gain power, economy and lower emissions all at the same time!!! Your O2 sebnsors and converter will last 3 times longer!!! GOOD LUCK!!
Where is the knock sensor located in a 2001 Chevy impala 3.8 liter 6yl 3800 series and how do you get them off?
The KS (knock sensor) is located under the exhaust manifold on the front side of the engine! Did you retrieve either a P0327 or a P0332 from the PCM (powertrain control module)? CAUTION: Hot engine coolant may cause severe burns. Although the cooling system has been drained, coolant still remains in the engine water jacket. This coolant will drain with the removal of the KS!

Help with 2001 Chevy Impala code P0420?
It is quite possible that the faulty MAF (mass air flow) sensor is what cooked your converter! Also the upper intake should be checked for cracks and sucking coolant (this is a very common problem with the 3.8L and this will kill the converter! ADDED: @ BrettH... Are you some kind of idiot? You are not worth you weight in puke if you think a Catalyst Efficiency code has to do with the EVAP system! A P0420= Catalyst System Efficiency Below Threshold (bank 1) now how in the world you got a gas cap out of that I will never know! My suggestion to you is to go here http://www.autoshop101.com/ So you go learn about cars! And if he didn't put the gas cap on he would have a P0440 or a P0455!!!
My 2002 Chevy Impala is showing a P0141 OBD-II error code ????? Which Oxygen Sensor is this referring too?
Hello! I have a 2002 Chevy Impala with a V6-3.4L engine. Recently my check engine light came on. I have an OBD-II code reader, so I read the code and it showed an error code of P0141. Upon researching this code it looks like one of the oxygen sensors on the car needs to be replaced. The problem is I am not sure exactly what sensor needs to be replaced. I keep finding conflicting information on if my car has 3 or 4 sensors and I keep seeing different labels for the sensors. The code is saying it is the sensor in (BANK 1, SENSOR 2) that needs replacing. If my car has 4 sensors (one on each side of the V, one before the Cat and one after the Cat) I am assuming that it is the sensor before the Cat and can be reached from under the hood. If my car has three sensors(one on each side of the V, and one after the Cat), then I'm assuming that the sensor located after the Cat is the sensor that needs to be replaced and that the car will need to be jacked up and the sensor will need to be changed from underneath the car. Thanks for any help you can provide me with.
2001 Chevy Impala Check engine light?
If you can drive it it's driveable. Malfunction in the emission control system means "exhaust" could be a leak, if there's no problem with the driveability or noise then go with it if it's not under warranty. When I had a leak (I have a GM car) it was the flexpipe at the downpipe flange. Could be there...it's going to be somewhere before that 2nd o2 sensor so that's a good start. I would guess that flex pipe or at the downpipe flange. If it was a header leak then it would register another code as well (I think don't quote me). Midas will take a look and change the gaskets if need be for under 30 bucks...well most will.
What are some symptoms of a bad idle air control sensor?
Idle air control valves open to allow more air to "leak" into the intake, raising the engine rpms, or close when not needed. When your AC compressor kicks in or power steering is activated as you suddenly turn the steering wheel, the sudden drag on the drive belt will bog down the engine. These systems send a signal to the engine computer telling it they are active and it then signals the IAC valve to open, which increases the engine speed. Without this occurring, the engine could struggle, or die. The IAC valve can cause weird idle issues, mess with throttle functionality or cause the car to die. Sometimes they fail, get stuck or just get all carboned up. Sometimes people have success at cleaning them, but generally it is best to replace them when bad. Idle issues and even problems with the IAC valve may not be due to the IAC valve being bad itself. An idle issue does not mean the IAC valve is bad. It is best to pay close attention to how the vehicle is acting, and then communicate that clearly and as completely as possible to your mechanic. Intermittent problems can be very hard to diagnose. Details will help. Knowing more about the vehicle in question and its symptoms (in detail) will also help in understanding more about what it is doing.
What are the symptoms of a bad transmission speed sensor?
On some vehicles, there are sensors that function specifically for certain parts of the vehicle. Sometimes a bad speed sensor will mess up the function of the ABS brakes (causing them to overreact or not kick in at all, which usually creates a light on the dash), other times it can cause erratic speedometer readings and/or (for auto transmissions) cause inconsistent shifts and it shifting completely out of gear into neutral at random. Some vehicles it will do all of these things at once, but you should get a CEL (check engine light) or ABS light to show up on the dash if one of these things are becoming problematic enough to cause issues.
