Avalon 2005-12 :: 2006 - Error Code P0031 / Heated Oxygen Sensor Is Bad
Oct 26, 2015
I received error code P0031 on my 06 Avalon the other day. It states that the HO2S (Heated Oxygen Sensor) is bad. Bank 1 Sensor 1. I located the sensor but have a few questions...
Just to give an over view for those that don't know where these are, there are 4 sensors the one in the front on the manifold (upper - B2, S1), (lower - B2, S2) and the rear manifold (upper - B1, S1), (lower - B1, S2).
All of the sensors look the same with 4 wires. what the part number is for the sensor? Also since this is the hardest one to get to, I would like to know where the wire routes to. I found the wire up to the connector on every other sensor except the one I need (B1S1). It looks like it runs towards the top of the engine but from the top I don't see it.

I have a check engine light come on in my 07 Avalon and had the car scanned. It was throwing error code P0031. I'm gonna go ahead and replace this O2 sensor, however, I'm having a hard time finding the correct part# for this sensor.

I have a 2001 Exrursion 5.4L V8. The code P1131 comes up and it says "Lack of upstream heated oxygen sensor switch - sensor indicates lean - bank #1". I hear it could be the sensor that is bad or there is a vacuum leak. It runs like a champ, no spitting, no sputtering, no missing, no ruff idle. What do I need to do to fix it or where do I need to start looking?

So of course it has to happen 3 weeks after my warranty expires. My CEL comes on and I have it read and the result is P0440. I find out that my wife has a habit of topping off the gas tank and so I am thinking that she has probably ruined the charcoal canister. It is something easy to replace?
I have an 06 limited edition... Yes, she will not be topping off any gas tank anymore.

Have the P1705 engine code (Direct Clutch Speed Circuit Fault) on 1996 Avalon.
I have removed it and trying to examine connectors and unit for problems.
Seems simpler to replace but cannot see spending the money on a crap shoot. Here is what I know:
Took voltage reading from each of the 2 connectors on the harness each with the key on but car not started. 1 probe to 1 connector and other probe to battery ground. Each connector displayed 0.76V.
Checked resistance across connectors on removed Sensor and it was 600+.
So...are these results determine whether the sensor is bad or the connector harness has an issue? Am I measuring incorrectly? Finally, is there only one of these sensors? I see on later models there are 2. Toyota P/N: 89413-08020

2006 Toyota Avalon 72000 miles
Plugs and coil have been switched between Banks 1,3,5 with 2,4,6 code P0355 shows the same cylinder 5 after the switch. What's the difference between a PCM and ECU and which one do I have.

I have a 2010 Toyota Corolla 1.8L, the base model.
I recently had a check engine light, VSC off light (blinking) and traction control light come on. I took it to Autozone and had a p0037 code ring up for a new Bank 1 Sensor 2 oxygen sensor (downstream). I believe I have found the correct sensor (located under car, approximately near drivers seat) and it looks simple to replace, aside from the fact that the wires go through the car body.
Can confirm that I have located the correct sensor? And if so, what is the best way to get to where the wires connect?
Is it located under the drivers seat? What should I do about the rubber grommet located under the car where the wires appear to pass through?

I have a CEL on my 2007 Avalon so I decided to take it to Autozone to get a scan. Error code P0015 was returned. This code has to do with B Camshaft Position, Timing Over Retarded (Bank 1). I've done a little research and I've read that this could possibly from a dirty screen on the Oil Control Valve, the OCV itself, or the Cam Position Sensor. Before replacing parts, what I would like to do first is to check/clean the screen on the OCV. Secondly, I would like to swap the Cam Position Sensor to a different bank and see if the other bank throws an error. If the other bank throws an error, then I know the sensor is bad and needs to be replaced. With this said, I am having trouble locating the OCV and CPS. Where the valve and sensor is located. A diagram would be useful.

The service truck threw a CEL, and i pulled oxygen sensor performance bank one sensor one code. That would be driver side sensor between the manifold and cat, rite? Don't want to change the wrong one...

The 2005 Avalon has 48K miles and it's been running well without any issues, until today.
Driving in city traffic, max speed is about 30 ml/h, The "Check Engine" light and the "VSC (Vehicle Slip Control) Off" lights came on. I did stop the engine, restarted after couple of minutes and the same lights stayed on. The car ran just fine, no noticeable difference in performance.
With the OBDCOM reader, the Avalon has this code:
P0351 232
P0351 Ignition coil A primary/secondary circuit malfunction
That seems to indicate a malfunction for cylinder A, or #1, ignition coil that has nothing to do with the "VSC" AFAIK. Is this a misread by OBDCOM reader, or the Avalon is confused?
The code had been reset via the OBDCOM reader, the car runs fine, neither of the lights come on now. Should I do something about coil A, or just wait until the code comes back?

So, my '06 XL just popped up a P0051 code, which is the bank 2, sensor 1 (the upstream A/F sensor that you can easily view upon opening the hood in the front exhaust manifold. Easy enough of a replacement on that one, but what about bank 1, sensor 1 (the upstream A/F ratio sensor on the firewall side of the engine)? I changed my oil today and I can access three of the four oxy/A/F sensors, but the upstream rear looks like a bitch! Out of curiosity, I called a local Toyota dealer and they said it would be 300.00 total to replace the hidden sensor on the firewall side. Does this amount seem realistic? I know that there is a TSB for this sensor that states to replace the exhaust manifold/cat assembly. I def. can't afford no 1700.00 crap right now!!

I have an 08 avalon w/ 281k miles. NEED to replace the transmission speed sensor (P0500 code thrown). Where is it located on the trans and what is the part #? I'm thinking about servicing the trans while I'm there but looks like a lot of "comments" regarding this transmission and the problems with servicing it!?

So, I have my check engine light and the code is p0327 (knock sensor). Clear cose but it returns. Going on for 3 days now. I was suspicious that something else is going on. I also remembered I've been using a little more antifreeze in the reservoir. So, today I needed to watch the coolant. I ran the car for an hr and I found a lot. Red coolant on my belt, the back passenger side of my engine and it was caked on with coolant. I think the water pump is going up.
I was concerned that coolant was also leaking from the intake manifold but it's only the right side, so I'm pretty sure the coolant is being slung around from the belt. I rinsed the engine down and the knock sensor code went away. Temporarily, until more coolant got back there. Do you think I will need to replace the knock sensor along with the water pump or should the sensor work ok after some intense cleaning after the water pump replacement?

I try to do my own maintenance. I have a 2006 Avalon Limited. This has happened twice recently, using cruise it has kicked off and gives me the VSC light and the check engine light and cruise error, when running codes I get the following P0138 & P2195 both have to do with the O2 sensor on bank 1, and P1578 & P1201 which are brake malfunction. I have been searching the Internet for any information on what could be causing my issue with no luck. I have a 3000 mile trip and need to figure this out soon.

My Jetta has been throwing this code on and off for over a year now. It used to only come on when it was really cold with wet roads. Now the code will randomly come on in any weather. I usually just clear it but it's coming on to often now. I don't notice any performance issues or gas mileage problems.
Scan shows : Trouble Code - P0420 Catalyst System Efficiency Below Threshold (Bank 1)
I've been reading and apparently 1.8t engines only have One bank? I'm assuming this the the front 02 sensor throwing this but not sure?
I have an aftermarket exhaust/high flow cat. Apparently this can be caused by a high flow after market catalytic converter and one solution is to use a test pipe or spacer to move the rear O2 sensor further from the exhaust gas flow. But I'm not sure this is the issue since I think it's my front sensor throwing the code? That's not by the Cat is it? I just don't want to have the sensor replaced to have the code still come up.

Replaced 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..

My check engine light came on the other day, and I went to Autozone to have the code read. Of course, that indicated the camshaft position sensor was detecting a fault. I read through all the posts relating to the fault, headed up to my local Hyundai dealer, and picked up the oil flow control valve for about $50 plus tax. While I was there, I figured I might as well have them do an oil change, since it was way past due. No point in putting in a new part with dirty oil..right? They did the oil change, washed the car and I was ready to roll. My plan was to replace the part myself, but magically, the check engine light has not come back on since.

VSC, Check engine light just came on my 2006 GS300. I only have 50k miles on it. I had this happen a few years back and it was the Gas cap o-ring. This time I changed the gas cap and reset the codes but no luck. After starting the car, with a minute the lights come back on. So checked the code and here is what I'm getting:
P0031
Heated Oxygen
Sensor Heater
Control Circuit Low
Bank 1 Sensor 1
Doing a search for the code yields this: [URL] .....
Changing the sensor vs. checking something else that might be the issue?

I have a hyndai Sonata v6. It is 2006 model and has done 86K miles. It recently failed the inspection and I was told it has faulty oxygen sensors. I have replaced the sensors. But now I am advised by the mechanic that I need to drive abut 200 miles before I can take it for the inspection again because it takes some time for the sensors to get adjusted. Is that true ?

2006 Avalon Limited: getting a P0015 code. My mechanic says it has to do with cam sensors(?) "cam pos actuator b bank 1: timing over retarded." Dealer told mechanic that they've never seen one of these sensors go and to check the wiring harness for damage; mechanic found none. 153,000 miles.
