2002 Buick Regal Service Engine Soon light PO442 diagnostic code


That is an emissions code. It means you have a small leak in one of the lines. Most likely it the line that goes from the engine to the evap canister in the drivers side rear inner fender well.

A simple google search reveals this is a small leak in the emissions canister system vacuum lines. This can be as simple as a bad gas cap, or a cracked or broken vacuum hose.

Check engine light on Toyota sienna 2000 stays on


have an auto parts store scan the computer for you.
They most often do this for free (oreilly auto parts and autozone)

Write down the code they give you. Should start with "P" (po442, P1406, etc)

That will be the problem, and they will most likely offer you the part right there.

Toyota is big about EVAP system trouble codes (chech engine lights)

But it could be anything, so this should be an easy fix.

You can even ask them at the parts store where the trouble part is located.

let me know once you find the problem code and I can help more.

Check engine light on. Won't stay off. OCD code is po442 po128 coolant.


Just fixed mine with the same code and gm tech advised me to change thermostat which is not a fun job as it is located in the LOWER hose and comes with a gooseneck assembly and O ring.The temp sensor could also be the problem but was told not likely so got by with just thermostat!

Troubleshooting code PO442 check engine light on. When I put in gas, gas nozzle keeps cutting off like tank is full


The code PO442 is a small leak somewhere in the evaporative emissions control system, the best way to find that is to take to a shop that does smoke tests for emissions.
As far as the nozzle, try changing the position of it the next time you get gas.
