04 tacoma. 6cyl. 60k miles. threw a code today, hooked up my scanner and told me this :
code number - P0442
read : EVAP EMISSION CONTROL SYSTEM LEAK (small)

can anyone help me out? tell me what i can do to fix it?
 
Make sure your gas cap is tight.
 
thats a fairly ambiguous code it means that there is a small vacuum emissions leak.i work for toyota and we usually just reset the light and see if it comes back .if it does come back we will generally run a smoke test on the system .another thing to check is the charcoal cannister.
 
yeah i read up on it on the internet after i posted it. since you work for toyota, you know where i can get a transmission range sensor as well?
 
small leak means the computer can see like a .010" leak some where. And it finds it by measuring the vacuum loss when check the evap system

Alot of times they are accidental codes, but a smoke machine will find it in like 30 seconds.

Get the range sensor at Toyota
