Question From john7 on Oxygen sensor

2006 Toyota Tundra Problem with 80000 miles Hi guys, my toyota tundra with v-8 is not going to pass emmission test in washington because of check engine light. I took it to Auto zone and they said it was oxygen sensor bank 1. Is this something i can tackle? They gave me a quote of 149.00 for a new one. Any advice would be great. Im a pretty good mechanic so if its easy ,ill try.

Response From Discretesignals

What is the trouble code number?

Ill have to have it checked again....thanks for replying.

Response From Tom Greenleaf Top Rated Answer

Keep in mind sport that these "free" code readings are mostly to sell you parts that might not be needed. Especially an O2 as something else could set that off. It could be unplugged or who knows yet? - T

Question From fuelhauler on Oxygen Sensor

1988 Toyota Corolla 1.6 liter 250,000 miles. I changed my exhaust manifold and exhaust pipe from the manifold to the catalytic converter. On the new exhaust manifold, the position of the oxygen sensor is different. Now that the sensor is in a different position, the wire will not reach. What effect will this have on my engine? By the way, the engine is carbureted, not fuel injected. Thanks for any information.

Response From Loren Champlain Sr

The O2 sensor is important. Sounds like the incorrect manifold. Maybe, they sold you one for fuel injection? That was about the time that they were switching from carbs to injection. The O2 sensor is for your feed-back carb and helps to control fuel delivery.

Response From fuelhauler Top Rated Answer

It is an aftermarket manifold to let the engine breathe better. Everything else was the proper fit. I test drove it after the change, and there was a big difference in performance. Can i splice a wire in between the two plugs, to fix this problem? Or do i need to try and find a sensor with a longer wire? Will the car be o.k. to drive about 4 miles to work tomorrow? Will it just use more fuel, and possibly not cause any other problems? Thnks

1998 Toyota Cor. VE Oxygen Sensor

Showing 2 out of 2 Posts
Question From wcatesjr on 1998 Toyota Cor. VE Oxygen Sensor

Bought the car in 2003. Drove it off the lot and several weeks later the engine light came on. Brought it to my local mechanic and he told me it was the ox fuel sensor. Got it replaced and several weeks later the light came back on. I reset the light but after just a few days or weeks it comes back on. I had it hocked to diag. and still says the ox fu sens. So now I just ignored it. 2007 NH state law now requires light to be off. POOP!! Went for my inspection - mach. told me to get it replaced. I told him my issue but he didn't seem to listen. Got it replaced and two weeks later light came back on. In 2008 I reset it before getting inspec. IT PASSED! But it came back on. I've had it replced three times now.

I'd rather use my engine light for what it was intended. Any help?

Response From Loren Champlain Sr Top Rated Answer

wcatesjr; The O2 code tells you that there is a problem in that system. It doesn't tell you that the sensor is bad.
Could be a circuit problem or even a computer problem. Find a shop that has the capabilities of diagnosing. Anyone can 'replace' parts. If you ignore this, catalyst damage is probable. And, don't clear the codes before you take it in...It is also possible that you are getting low-quality sensors. I would recommend using Toyota sensors, but if not, Bosch are good quality, too.

Toyota tacoma 2010 p0138

Question From jstem4 on Toyota tacoma 2010 p0138

Hello guys, I have a 2010 toyota tacoma Sr5 with the 2.7L 4x4. I have 60000 miles on it.

About a year ago i started to get the p0136 code. After a few time resetting the DLC with no success to clear the codes for good( the codes kept on coming back after 60 to 150 miles ).
Not long after that i got both the p0136 and the p0138 codes, and for about 6 months i only have the p0138 codes.

I replaced my rear oxygen sensor with a brand new Ntk oxygen sensor but that did not the trick. I also tried some spark plug non foolers without any success either.

I have the software Scan xl the read the Obd2 data. Here is the freeze frame data from my last DTC p0138 code.




Response From Discretesignals Top Rated Answer

Freeze frame data is great, but you need to monitor the Bank 1 sensor 2 voltage. According to the freeze frame at the time the code set the voltage was around .80 volts, but that is only one frame of data. Not much help. You need to monitor a live data stream and see what the rear sensor voltage is doing.

If the rear sensor is hanging at high voltage, create a big vacuum leak and see if the sensor goes low. Let us know what you find out. Also take note of the AF sensor voltage when you create the big vacuum leak. The A/F voltage should go higher than 3.3 volts.
