As I mentioned, I pulled the MAF sensor and cleaned it with brake fluid, reset the codes and ran well and still running well, except the check engine light came on in 30 days, not immediately. It was only running the car at 75 mph did the light re-occur. I can't believe it would be the oxygen sensor...wouldn't a problem show up immediately with the check engine light? And have you heard of any problem with oil burning in 2000 prizms? Tks. Rex

    I was told to use brake fluid by a mechanic to clean the MAF.

  • rexdoesch227 Nov 14, 2008

    And I was also told by this mechanic that most check engine lights are not due to the oxygen sensor, which seems to be corroborated by others on the net. And that the culprit might be a vacuum leak. Rex

    Sorry...it was brake cleaner...car only has 50,000 mi...do oxygen sensors go bad that soon?

  • rexdoesch227 Nov 14, 2008

    Also, what damage occurs to the engine or catalytic converter by running the car at lean (171 code). It seems that I am getting better mileage since the code came on.....and I can probably pass emissions by resetting the code (pulling the neg. battery cable), since it runs for weeks before check engine light comes on...tks, rex

Most likely replacing the O2 sensor will fix this code, but that is not 100%, it could be other issues like a vacuum leak or a MAF sensor. The O2 is the one in front or on the engine side of the catalytic converter.

    Why the thanks for trying, the info I provided was correct based on what you wrote in this thread/post, I have no idea why you think I would know you cleaned the MAF, and cleaning the MAF is not always the problem, many times the sensor is defective and no amount of cleaning will cure that, O2 sensors cause intermittent check engine lights more than any other sensor, that is based on 20 years of almost nothing but emission repairs, I was a unlimited Smog tech for the state of calif for 30 years, what I have told you so far is correct. The Thanks For Trying is unfair

    Oh, no I have not run across a real oil burning concerns with this car, but they are a Toyota Corolla and perhaps you should research those cars, they are the by far much more numerous.

    Why did you use brake fluid to clean the Manifold air meter??

  • yadayada
    yadayada Nov 14, 2008

    Lets se how would you account for 3 or 4 thousand O2 sensors I have replaced for phantom lean codes? No, the other techs are wrong, vacuum leaks are easy to ID, you spray carb spray around the intake area and if a vacuum leak is present then the O2 will go to a high voltage reading, if nothing happens then the O2 is defective and does not switch up and down as fuel trim is adjusted, are you sure the mech didn't tell you to use brake clean, not brake fluid?

    You read blogs I worked as a class A smog tech for 30 years, I do know what I am talking about, I have decades of field work to prove it.

    No damage to the cat will occur, a very rich condition will burn the cat out from overheating, but they like lean. What about doing the fair thing and changing the rating.

Why the check engine light comes on and off runs great


The check engine light is on to tell you the computer has found a problem that will affect performance, gas mileage, or emissions.
Such as the code 171 you asked about.
Code 171 is for the fuel mixture on bank one being too lean. The O2 sensor is telling the computer the fuel mixture is too lean and the computer can not make it rich enough.

Check engine light codes and troubleshooting


Sounds like you have a vacuum leak for the lean code and the misfires. I don't see a 473 code in my manual, but have a 463. The 463 is for the fuel level sensor open or voltage high.

2001 Toyota Corolla, Burning Oil rapidly


hi, the main cause of major oil consumption is due to cylinder wall deterioration. this is caused be bad piston ring sets that tend to chip of tiny pieces of the cylinder walls over a long period of time. this will start to show in engines with high millage. this will also lead to compression loss as well if it is not fixed soon.

To fix this issue within the cylinder walls, they will have to be machined and a new set of piston rings will have to be fitted around each affected piston. this will stop the oil from leaking into the combustion chamber and it will restore the compression rate as well.

2000 Prizm


Hi....
Is there a few possibilities for a Low mileage per gallon on any car.
But I will mention the more Importants.

The Spark plugs.
Depend on the Mileage on your car, Normally For a Prizm.
The spark plug should be changed every 30,000 Miles.
With Factory Dippon Denso ( ND) or NGK. Both are factory replacement.

Check for any Vaccum leak on the Intake Manifold and The Big Rubber hose from the Throttle Body
To the Air filter.. Or any restriction on the Big rubber hose.

Is very Important to Have changed the Oil every 3,000 miles.
Incredible But Old oil made any car to have low mileage per gallon.

Check the condition of the Transmission Fluid .
Is nessesary to change the first time at 60,000, and after Every 20,000 or 30,000 miles.
To old or burn Transmission fluid made the car run on more RPM to get power.
Compare with new oil ,

Ok. is there a few more things but check this first and let me know.

I hope this help on your question.
Thank you for use fixya.

1993 Geo Prizm lack of horsepower


Clean the mass airflow sensor (or replace it outright) and change your oxygen sensor. Those are very big contributors to fuel mileage. Also, verify that the new plugs are gapped correctly.
