If the problem is with the rear (downstream) sensor, you can replace it by yourself. The downstream O2 sensor will be after the catalytic converter. Simply disconnect the connector and using the socket wrench, take the sensor out. Install a new connector by splicing the wires and then connect the new sensor back to its place along with the new connector. You can find Delphi O2 sensor at best price from oxygensensorworld.com

Which Oxygen Sensor Is It?


There are many inquiries online about which oxygen sensor to change. Oxygen sensor failure codes are very common on a lot of vehicles. With all of today's vehicles having at least two oxygen sensors and many having three or four of them, it can be a little confusing as to which one is causing the problem.

Before we get into which sensor is which, we need to have a little discussion about oxygen sensor fault codes. There are several different types of oxygen sensor fault codes. Here are just some of the most common ones:

P0135 "Oxygen Sensor Heater Circuit Bank1 Sensor 1"
P0141 "Oxygen Sensor Heater Circuit Bank 1 Sensor 2"
P0147 "Oxygen Sensor Circuit Bank 1 Sensor 3"
P0152 "Oxygen Sensor Voltage High Bank 2 Sensor 1"
P0159 "Oxygen Sensor Slow Response Bank 2 Sensor 2"
P0171 "Oxygen Sensor Lean Sensor 1 Bank 1"
P0172 "Oxygen Sensor Lean Sensor 1 Bank 2"
P0174 "Oxygen Sensor Rich Sensor 1 Bank 1"
P0175 "Oxygen Sensor Rich Sensor 1 Bank 2"

There are many more possible oxygen sensor codes, but I only listed these to make my point. Many times the oxygen sensor code is NOT caused by the oxygen sensor itself. "Lean" or "Rich" oxygen sensor codes (i.e. P0171, P0174) are usually caused by something other than the oxygen sensor. Something is wrong, causing the engine to run lean (not enough fuel or too much air) or causing the engine to run rich (too much fuel or not enough air). In these cases, replacing the oxygen sensor will not fix a thing. (That is, unless you are trying to fix your bank account from having too high of a balance!) The new oxygen sensor will just set the same code as the original one. This is because the oxygen sensor is not CAUSING the problem, it is only REPORTING the problem.

High voltage codes (like P0152 above) can be caused by the oxygen sensor wires being shorted to another wire inside the wiring harness. Sometimes these codes are caused by bad grounds where some other component is trying to ground through the oxygen sensor circuit. Again, replacing the oxygen sensor will not fix this! In short, the problem needs to be diagnosed before running out and buying an oxygen sensor.

Just because a fault code has "Oxygen Sensor" or "O2 Sensor" or "O2S" in its description does not necessarily mean that an oxygen sensor needs to be replaced. Many do-it-yourselfers believe that all there is to fixing the car is to hook it to the "magic box", collect the fault codes and replace the parts the computer tells you to replace. There is nothing further from the truth.

Fault codes only point you toward which SYSTEM is failing. The system must be diagnosed to find the CAUSE of the failure. If this is not done properly, it will only result in wasting a bunch of your money. This is what you were trying to avoid by doing it yourself!

So, after reading all of the above, if you think you still want to replace an oxygen sensor, but don't know which one; here is how to figure it out:

Oxygen sensors are always numbered like this:

Bank 1 Sensor 1
Bank 2 Sensor 1
Bank 1 Sensor 2
Bank 2 Sensor 2

Some manufacturers use a kind of shorthand that reads different, but means the same thing:

Sensor 1/1 or O2s 1/1
Sensor 2/1 or O2s 2/1
Sensor 1/2 or O2s 1/2
Sensor 2/2 or O2s 2/2

Bank 1 is always the side of the engine where cylinder #1 is located and, of course, Bank 2 is the opposite side.
On a 4 cylinder engine, there is only one bank and it is always referred to as Bank 1. The exception to the 4 cylinder rule is on certain 4 cylinder engines (specifically, some Toyotas) there are two catalytic converters used. In this case, Bank 1 sensors will still be in the pipe for the catalyst that is connected to cylinder #1 and Bank 2 sensors will be in the other one.

Sensor 1 is always the "upstream" sensor (the one located BEFORE the catalytic converter).
Sensor 2 is always the "downstream" sensor (the one that is located AFTER the catalytic converter).
Sensor 3 refers to the ONLY "downstream" sensor where there are two sensors before the catalyst and only one after the catalyst. On very few vehicles the reference to this reads "Bank 1 Sensor 3".

If you do not know where cylinder #1 is, then you need to get a diagram of the firing order for your engine. Just post a question on FixYa.com and make sure you give the YEAR, MAKE, MODEL, and ENGINE SIZE of your vehicle and one or more of our experts will be happy to tell you how to find cylinder #1.

2006 Suzuki Verona has two upper oxygen sensors


odd question both split, mans are one same side of the I6 !
the Daewoo Magnus , in drag.
no country stated, (canada, calif? , usa Fed states)?
no engine stated,?
no PCM DTC error stated, (context of question not stated)


bank one 02 is on cylinder 1 side.
some in line 6 engines have split exhaust manifold.
for california cars.

ill try go get this info,guessing all the above.


the inline engine, bank one sensor 1 is that sensor closest to
cylinder one or the cylinder closeset to the crank shaft pulley.

ok I looked in the USA FSM online
and sure there is a I6 with s split man, with 2 CATS/
got 2 CATS, right>?
that is your confusion, id bet.
so bank 1 is closed to cylinder 1
bank 2 is closed to cylinder 4.
Pulley, 1,2,3, 4,5,6
no mater what Suzuk BODY or driveline this engine fits.
Bank 1 is at the CRANK SHAFT END PULLEY.

How to fix error code P0153 Slow Response Bank 2 Sensor


This involves the oxygen sensor upstream the catalytic converter on Bank 2. This code indicates the engine air fuel ratio is not being adjusted by the oxygen sensor signal or the ECM as expected to do so, or not adjusted as often as expected to do so once the engine is warmed or under normal engine use. You will likely not notice any drive ability problems, although there may be symptoms. A code P0153 may mean that one or more of the following has happened: The oxygen sensor is faulty The wiring to the sensor is broken / frayed There is an exhaust leak Possible Solutions Things that may fix the problem include: Check and fix any exhaust leaks, Check for wiring problems (shorted, frayed wires), Check the frequency and amplitude of the oxygen sensor (advanced), Check for a deteriorating / contaminated oxygen sensor, replace if necessary, Check for inlet air leaks, Check the MAF sensor (sensor of the pipe from air cleaner) for proper operation, Replace the Bank 2 oxygen sensor upstream of the catalytic converter (follow from CC towards engine - you wil see the sensor)

How many o2 sensors are on a 1999 Silverado 5.3


The 1999 5.3 V8 engine had 4 oxygen sensors. There are two catalytic converters on this engine, one on the driver side of the engine, and one on the passenger side of the engine. This is important to know, as the number of oxygen sensors is directly related to the number of catalytic converters on the vehicle. Driver side is referred to as Bank 1, passenger side is referred to as Bank 2. This is very important to know when looking up replacement oxygen sensors. There is one oxygen sensor in front of, or before the catalytic converter, usually referred to as a pre-catalyst O2 sensor. There is also one behind, or after the catalytic converter, usually referred to as a post-catalyst oxygen sensor. So, you have two oxygen sensors on Bank 1, and two oxygen sensors on Bank 2, for a grand total of 4 oxygen sensors.

I think you need Bosch for that vehicle. here is a rundown how it helps


Every automobile manufactured after the 1980s is equipped with an oxygen sensor. This component measures the ratio of air and gasoline in the engine and feeds the data to the vehicle's computer. With an oxygen sensor, your engine runs more efficiently and produces as few emissions as possible. If your car's running with a busted oxygen sensor, you better get a new one before your engine's efficiency takes a nosedive and your gas bills skyrocket. We know that looking for the right replacement oxygen sensor can be very tricky, that's why we've come up with a guide for you to keep in mind when shopping for a new oxygen sensor.
Which oxygen sensor should you buy?
There are a lot of questions about which oxygen sensor to replace. In fact, failures are common among cars especially when the wrong sensor is installed. With today's automobiles equipped with at least two, or even three or four oxygen sensors, it can be very confusing as to which one is not working correctly. There are probably a lot of sensor codes to choose from and here's a tip to help you sense the right oxygen sensor.
Oxygen sensors are always numbered this way:
Bank 1 Sensor 1
Bank 2 Sensor 1
Bank 1 Sensor 2
Bank 2 Sensor 2
Other manufacturers code their oxygen sensors this way, which is why it can sometimes be very confusing. However, they all mean the same:
Sensor 1/1 or O2s 1/1
Sensor 2/1 or O2s 2/1
Sensor 1/2 or O2s 1/2
Sensor 2/2 or O2s 2/2
Now here's a detailed list to know which is which:
  • Bank 1 is located at the side of the engine where cylinder #1 is found as well.
  • Bank 2 is on the opposite side of Bank 1.
  • On a 4-cylinder engine, there is only one bank that's called Bank 1.
  • Sensor 1 is the upstream sensor located before the catalytic converter.
  • Sensor 2 is the downstream sensor located after the catalytic converter.
  • Sensor 3 is the only downstream sensor in situations where there are two sensors before the catalytic converter and only one after it. On other cars, this is read as Bank 1 Sensor 3.
With these detailed tips on how to sense the right oxygen sensor, you'd be sure to buy the right replacement part at your store. Be sure to purchase one from a trusted brand to avoid any complications you might experience with ones that are bought from local junkyards BEST OF LUCK

P0037. heater sen. where is it on the engine?


The code is for the heater in the O2 sensor bank one sensor two. That would be the sensor after the catalytic converter on bank one.
It could be the sensor itself or the power supply for the heater.

I recently bought a 2000 lexus rx 300> check engine light came on and i was locked out of overdrive< knock sensors and wiring harness with oxygen sensor replaced for !000. now check engine...


I had the same problem with my RX. Had both knock sensors replaced and the problem went away. Be sure to take it to a Tech that has a good scan tool so he can pull the codes and narrow down the problem, From what I understand a constant check engine light is usually not a big deal probably a sensor but a blinking light means major trouble. Take it to a shop that specializes in Toyota and Lexus.
