I got a code P1150 only 2000 Sienna LE, which I guess means Bank 2 Sensor 1. I am looking at Denso replacement part. It has upstream left (234-9007) and upstream right (234-9009). Is bank 2 sensor 1, upstream left, or right?

2002 Toyota Highlander P1135 A/F Sensor Bank 1 Sensor 1

The air-fuel ratio sensor is located in either the exhaust manifold or the front exhaust pipe. It measures the amount of air in your exhaust and uses that information to determine your current air-fuel ratio.

2005 Dodge Durango 4.7 giving a P0175 code. Could it be a leaky exhaust manifold?

Did you clean the Throttle body? That is often the cause of a rough idle.

The Fuel Air o2 sensor on the manifold is often hard to reach, but the downstream o2 sensor after the catalytic converter is easier to get to.

Code P0172 indicates Bank 1 of the engine has a rich fuel mixture. P0175 indicates Bank 2 of the engine has a rich fuel mixture. Engine Bank 1 is the same side of the engine as Engine Cylinder 1. Engine Bank 2 is the opposite side of the engine. A firing order and cylinder location diagram may be needed to see which side of the engine is Bank 1 or Bank 2.
P0172 is triggered by the engine bank 1?"upstream" oxygen sensor and P0175 is triggered by the engine bank 2 "upstream" oxygen sensor. The oxygen sensor alerts your system when the condition is too rich meaning there's too much fuel int the exhaust stream or too little oxygen in the exhaust stream. The symptoms and causes will help you determine the exact issue and how to fix it.
Your bank 1 or bank 2 sensors will be referred to as "sensor 1" or "sensor 2". Sensor 1 refers to "upstream" sensors, or the ones near the engine and before the catalytic converter. Sensor 2 is "downstream" or after the converter.

Where is the O2sensor bank 1 at with a code of P0420. AND do I need to replace both sensors upstream and down. Or just the one that is showing up on the obd scanner.

Bank one is front side of cat. It should also tell u if it's cat 1 or cat 2. Depending on make an modle an yr. Catalyst 1 bank 2 is left cat back sensor. Catalyst 2 bank 2 is right cat back sensor. U do not have to replace upstream also. My o2 sensor Catalyst 2 bank 2 went bad. Had engine code for burning rich bank 2. Replaced tha down stream sensor an fixed problem runs better an better gas. This was in 97 gmc suburban. Idk what vehicle ur askin about. An I'm not to familiar with much about cars jus trucks an suvs.

Code P0031 says replace B1 S1

On a front to back engine b1 is the drivers bank. On a transverse engine b1 is the front bank ( b1 has cylinder 1, b2 has cylinder 2 in a v type configuration) s1 is always between the engine and the catalytic converter. Usually in the exhaust manifold or the down pipe.

2003 honda civic o2 how to replace And how do i fin out which once is it

Hi Jesus, Im AL the owner of Big As Auto Repair.

If you have a 4 cylinder engine then you will only have two 02 sensors 1/1 is upstream and 1/2 is downstream. Upstream is the one closet to the engine and downstream is the one farther away from the engine.

If you have a six OR eight cylinder engine you will have four 02 Sensors. 1/1 means Bank One Sensor One. 1/1 and Bank one means right bank and right bank means the side with the number 1 spark plug. SO, 1/1 means, "Right Bank" Upstream 02 sensor. 1/2 means, "Right Bank" Downstream 02 sensor.

2/1 means, "Left Bank" Upstream 02 sensor and 2/2 means, "Left Bank" Downstream 02 sensor. Hope this helps and please visit my auto-repair-website at: http://www.bigasautorepair.com/

Can an O2 oxygen sensor effect another sensor and give a false reading?

Check which side of your engine has cylinder #1. That side is bank 1. Bank 2 is the side opposite of bank 1. So bank 2 is not always passenger side. And since you seem to have extra O2 sensors, I would replace the other upstream and see what happens. Also the mass air sensor can give a trouble code issue to the upstream 02 sensors. Good luck. I've struggled thru this myself.

2007 Toyota sienna V6 P2197 code from Autozone diagnostic.

Solved. I have 2008 Sienna with Check Engine and VSC lights on. Scanned codes were P0051 and P2197. Oxygen Sensor Bank 2 Sensor 1 needs to be replaced. You can see this sensor on the right side of the engine when you open up the hood. You need to get an Oxygen Sensor socket (I used Tekton 7/8in 22mm which costs $9) and a wrench extension to reach it. Spraying liquid wrench a few times on the base of the old sensor also helped to loose it. The replacement sensor I used was Denso 234-9049 which costs $85 from eBay. Lights went off after the sensor was replaced. It took me 30 minutes to replace.

Where is the oxygen sensor, bank 1 sensor 1, located on a 2000 Toyota Solara? What is the best one to purchase for replacement?

B1S1 means first (upstream) , closest sensor to cyl. head , usualy at exhaust manifold.Bank 1 is cyl. head with cyl.#1 if you have V6 engine.
Best choice for brand - Denso.

Check engine light

Sometimes can be prematurely dirty air filter, sets off the air flow sensor, which sets off the o2 sensor. So might try new air filter first and erase codes and then see, before you spend more bucks than you need; then if codes return, do the flow mix sensor.

Ravi, I also have the same issue and confused between upstream left and right location.

I have problem with bank 2 sensor 1 and want to purchase a part. There are two part numbers 234-9007 for upstream left and 234-9009 for right.

So not sure the one on radiator (bank 2 sensor 1) side is upstream left or upstream right.

If you already know can you please reply?

I hate people like above can't give a straight answer, useless information. It has to be standing on the Passenger side facing engine - left side is BANK 1 SENSOR 1 (upstream LEFT SIDE)- I JUST REPLACED - DENSO 234-9007 Fuel To Air Ratio Sensor , so now I have to replace the other side P1150 - DENSO 234-9009 Fuel To Air Ratio Sensor BANK 1 SENSOR 1 (upstream RIGHT SIDE).

SOURCE: PO137, PO 138 codes

well on my car these are reffering to the sensors in the exhaust, the upstream sensor(before the cat) and the downstream sensor(after the cat) the downstream sensor can act up if it is lazy or sluggish, or due to a bad catalytic converter or a clogged one. however there are sensors on the exhaust manifold which are determined by driver side or passenger,my opinion is to get a scanner for about $100 to $150 and you can figure out many of these codes yourself.
