Question about 2001 Toyota Sienna

1 Answer

Service code of P420 on Toyota Sienna.

Hello. I have a 2002 Toyota Sienna with 127k miles. My engine light has been cycling off/on for several months. I just flunked my inspection and was told it's due to the engine light and emissions. My mechanic said there was a "service code" of P420 coming up and I should take the car to a Toyota Dealer. The dealer immediately recommended a Cat. Converter at $1,300. A friend's mechanic said this happened to her car and he "removed one of the spark plugs, let the car run "hard" for an hour and all the 'gunk' was cleaned out of the converter and it then passed inspection. What is your advice? Thank you.

Hi my name is Juan and if you can wait one more day I am at work and I don't have my book with all the codes and once I get to it I can give you more recommendations but don't thrush what the dealer say they like to do this because they do thing that most of the costumers don't know nothing about cars and most people make this big mistake in say yes ok and let them do the repairs sometimes they tell costumers that there vehicles have 2 or more problems and this is not true sometimes is just a loose wire and they charge hundreds of dollars but they never tell you oh it was just a loose wire is 30dls so if you really need a cat-- replacement take your car to a muffler shop they can also do this job and for a lot lot less they charge around 300 to 400 hundred dls for this thanks and I'll let you know your code tomorrow

2008 Toyota Sienna check engine light is on, diagnostic check reports code PO451. Checked the fuel cap, it is ok, anything else I can do? How can I reset so lights go off?


Hello and happy holidays
Fault code P0451 is a code for the fuel tank evaporative emission control pressure sensor, this sensor is located on the top of the fuel tank, the gas cap is not the problem here, as far as the check engine light goes it will reset by itself if the problem is fixed in 3 drive cycles (about 60 miles of mixed driving), to clear it you either use a scanner or disconnect the battery for 5 minutes, I do not recommend the battery method as it can cause you to loose vital settings in the control modules in the car.

2005 Toyota Corolla CE P0741 error code.


This fix comes from the service manager of a Toyota dealer, he is a online expert named Toyota Ed.

Toyota is aware of this situation. Production changes have ocurred to correct this condition.

Here is what you do: Take your vehicle to your Toyota dealer. Tell them that you have a P-0741 code, and you want them to apply "Toyota Technical Service bulletin TC008-04" to your vehicle. They will perform several tests, and if you vehicle is lower than 5 years old, and less than 60, 000 miles, they will fix it for free. This TSB is covered by the Powertrain Warranty. Additionally, Thay may replace the ECU with an updated unit, and that particular warranty is in effect for 96 months or 80,000 miles.

This will definatly cure your issue
