I have an 03 XtraCab Tacoma, 2.7L manual. I suspect the front O2 sensor is
gone. The Check Engine light is on, there was 2 incidents where the engine
could barely keep idle, and my gas mileage has taken a beating. I am hoping
to get a local mechanic to check the computer today. He said an OE sensor is
$260. I found a DENSO OE sensor for $188 shipped. Is swapping an O2 sensor a
big job?

I was throwing a signal saying left bank lean on my V6 with O2 sensor
as the probable cause. My symptoms weren't as drastic as yours but
cleaning the MAS (Mass Air Sensor) cured it. The check engine light
hasn't came on since then. A lot cheaper than replacing the O2 sensor.

You can pull codes for free at Autozone.

Replacing the O2 Sensor is much like replacing a spark plug. You might need
to buy a special socket, depending on how much access you have.

I bought the tool for under $10. I assume I'll need it again, so I added to
the collection.

There is no AutoZone where I live (Newfoundland Canada)

I may have tracked down what is known as an Air Fuel Ratio Sensor locally,
but people are stressing don't cheap out. DENSO apparently makes Toyota
sensors so I like to try and get that brand.

do you have a Checker? Any large parts place should have a Mass Air Flow
Sensor. Usually there is a refundable "core charge" for getting a new one.
But try cleaning the one you have first. Especially if you ventured near the
K&N oiled filter scam.

That's even better. I've not seen that method before ...

if you have mini fingers with full 360 degree rotation. The new sensor
comes with the gasket so all one would need is some hi temp sealer, maybe
something to break the bolts loose (some type of penetrating liquid) and
lots of patience.

You really should pull the codes BEFORE you do anything else. Check the
AutoZone Website to see if they have the same thing with a differennt name
in Canada. If not, ask your favorite parts store if they have a Tool Loaner
Program, and if they do, ask if they also loan the scan tool for OBD II.

I had a local mechanic check the codes and help me diagnose.

Local parts stores here can only get NGK brand for $400-600!! They were even
surprised. I have tracked one down, a Denso for much cheaper.

Thanks for the replies everyone.

Recommend you check the engine codes before spending a lot of money. Actron
makes a line of code readers that are inexpensive.

www.actron.com

The $80 US model also resets your lights.

You can purchase O2 sensors at most US auto parts stores for about $120 US
for Toyota OEM type Denso or Bosch. I've had good luck with the Bosch
units. They fit my Tundra well. The code reader told me exactly which one
to change #1 is forward and #2 is aft. The V-8s have 4 total. Don't buy
the cheaper generic ones - you want the factory type connector plugs.

I've also had to replace a couple of ignitors. Again the engine codes
pinpointed the problem unit. These are also about 120 each so trial and
error gets expensive.

Agree you may want to clean your MAS and replace your air and fuel filters.

Good luck. Post back if no joy.

Bubba
