Avalon 2005-12 :: P0051 Code - Hidden Sensor Replacement On Firewall Side
Nov 30, 2014
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!?

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.

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

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 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 need to replace the hub assembly on the rear drivers side of my 2005 Avalon touring. I just need to know if the hub is pressed into the bracket that it is bolted to with 4 bolts or not. I would prefer it be the latter but I just want to know what to do with it. I took it all apart but decided to put it back together once a saw the back end of it seemed to be pressed into the bracket. Maybe it's not, I just need to know how to get the original off and get the new one on.

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.

I have an '06 Toyota Avalon XL and I bought some Silver Star 9006 bulbs at AZ the other night, but when I got back home, pulled into the garage and popped the hood, I was amazed at how much of a PITA it looked to remove the low-beam bulb, especially on the driver's side. I'd hate to take it to the dealer just to get the frickin headlight bulbs changed.

P0051 together with VSC and VSC Off Lights
Over the weekend I had multiple P0051 and VSC and VSC Off Lights CELs
I have reset them using my OBDII scanner. It keeps on coming back.
This means the BANK 2 SENSOR 1 (just before the CAT) is reading low temps and therefore throwing a code. I get this.
Question is why do the VSC lights go "ON" too?
This started when I installed my ScanGage e this weekend. This is a change point.
Before I go purchase a Denso sensor, I would like to perform a series of tests:
1.Remove the ScanGage e. Test drive if any of the CELs (P0051 and VSC) come back.
2.If the same set comes back, clear the VSC lights code using our home made device.
If the VSC lights disappear and the P0051 comes back, I will replace the BANK 2 SENSOR 1 Oxygen sensor. Prior to replacing, I will check for wiring issues on this sensor.

A few days ago I noticed some oil leaking from the left (front) valve cover area and I suspect it's the gasket. Fortunately, I didn't see any leaks from the back cover. It seemed like an easy job to replace the gasket, but as I started to disconnect the wiring, e.g., cam sensor, spark plugs, etc., I can't seem to find a way to remove the black plastic wiring harness 'housing' out of the way.

I have to replace the torque strut mount in my 2008 Avalon XLS V6. I can't find the torque specs for the two bolts in my Haynes manual or at any online sites. Also, should I use either threadlocker or anti-seize on them?

I have an 06 Limited. The headlights have an auto feature so that they turn on in the night time. Well, how to change the sensitivity of the light sensor? Its always dark and cloudy where i live so i almost always want my lights on, but its not dark enough for the sensor. I know i can take it into the dealership to have it adjusted, but im curious to know how it is done. Also on a side note, is there a way to easily mute the audio from the steering wheel? it turns down the volume quite slow when holding the button down.

I have 06 XLS with 56,000 miles and about 3 weeks ago the check engine and VSC lights came on. It was fixed, a ignition coil on the 4 cylinder.
Now driving home today the check engine and VSC lights are on again! I was wondering should try to get the dealer to replace all the remaining ignition coils ?
Plus I read their was some type of manufacturer defect on the original ignition coils from the factory. Why Toyota won't recognize this issue ?
Two ignition coils in a little over a month . My first Toyota and I'm rolling with the punches .

I picked up a 2004 Prius with 150k. It has no check engine light and no codes with a scangauge. I hooked it up to a mini-vci with techstream and found the following: P3009-526, C1310 and B1421. The car will only start if you reset codes, then after a few minutes of running the red triangle comes back.
