Engine

Is a 2002 Toyota Tacoma direct injection or does the gas pass over the top of the valves ?

 

Injectors inject fuel into the lower intake manifold where it mixes with air and passes through the intake valves. Lower intake manifold, not lower intake plenum.

 

Does it pass over the valves or is it directly sprayed into the piston like a lot of newer engines sorry I didn’t get your answer

 

Into a mixing chamber and through the valves ie not direct injection.

 

Thank you guys for the help and yes I was wondering if they would self clean have a check engine light on p0440 and p0442 and I can’t find anything wrong with the egr system yet so trying to figure out why I could be thrown these codes

 

What engine?

 

Its the 2.7 4 cylinder

 

probably the charcoal canister or the gas cap. Need to get your system smoke tested.

 

Both are brand new

 

who installed it? What brand of parts were used?

 

I was told oem and not sure on gas cap but had it smoked and gas cap doesn’t leak

 

I would go back to the place and tell them you are still getting the codes.. every time I got a P0440 it was the charcoal canister.

 

Yeah the place told me that they are done working on it and told me to bring it to Toyota and have them fix it

 

Wow, that's pretty shitty of them to say.. I would be pursuing further action to get your money back if I were you.

 

Yeah I won’t ever go there again

 

Yeah, if you had it done by a shop and you're still getting the code, take it back!
the 0440/0442 codes have nothing to do with the valve train anyway...

EDIT, just saw your post about them not wanting to fix it. Sounds like you found a real winner of a shop there, that sucks!

Have they worked on it multiple times already and can't figure it out?

 

You could do your own test by pressurizing it and with a bottle of soapy water spraying it all over the evap system lines.

 

Yeah they’ve worked on it on and off for about a month and sad part is it’s a ford dealership that works on other cars as well

 

Great idea I will try that

 

That's messed up.
