When I start the truck it’s fine until check engine light come on and if I give it gas it stalls but if I burly give it gas it’s fine and I change fuel pump, filter, injectors,throttle body, más air flow sensor, tps , and I don’t know what to do I think it’s my speed sensor that come out my dash but I don’t know

Did you ever solve this issue? Sounds like a bad coolant temperature sensor. Sends bad data back to the ecu which will make the rest of the engine over compensate for air, fuel, either to much or not enough.
CommentCode P0441 after it fails Smog Test
Toyota Tacoma 2014 130000 miles
After putting gas into truck this code came on p0441. I replaced gas cap with OEM from dealership and problem still persist. I cleared the codes and I drove the vehicle 200 miles and turned truck on and off 15 times. Check Engine light came back on. I can’t pass smog unless I fix the issue and clear the code.

I bought a smoke machine, the problem seemed to begin at the top of the gas tank. Dropped the gas tank only to find a huge hole on the evap line that connects to one the gas filler tube lines.it is a pain in the butt. Id recomend taking it in 😭 dont know how im putting it back together 🥲.

The only fuse I could locate. I’m sure there is also a relay that controls the circuit.

Comment2007 toyota tacoma 4x4
Toyota Tacoma 2007 Trd prerunner 6 96000 miles
I have my tacoma with 96000 mile in it. Got it maintenance at a local toyota service center. They replaced spark plugs. After a few weeks I noticed that between 40 to 60 miles per hour my truck had a jerking or hesitation move. I physical check the 6 plugs...maybe it wasn't gapped correctly but they were. Also checked ingintion coils to see if they were burned or had any oil around...also looked fine except one of them was marked with an x in yellow. Scanned it as well an everything checks out or no engine light has turned on. What else could it be??

May be the Camshaft sensor or the crankshaft sensor. I had one do the same thing and I replaced both. In the end it was the Camshaft sensor. I still replaced both though. Hopefully it helps you.
