2020 check engine light

I started my truck the yesterday and noticed the check engine light was on and steady. I decided to drive it down the street and noticed that at around 1600-1700 rpms the truck would sort of “jerk” as if its having an issue shifting between 1st and 2nd gear. My truck is brand new I’ve had it for about 3 weeks and only put 851 miles on it. I’m surprised a check engine light illuminated so quickly after purchasing it. Btw the truck is at the dealership right now and am waiting for a diagnosis. Anyone else having this issue???

 

Toyota will say its normal.

 

Well first off if it is jerking I'd persoanlly stop driving it. It is not going to just go away.

Second use that toyota warranty and call the dealer.

Third pickup a cheap 50 dollar OBDII reader from Amazon to save yourself a call and trip for something as trivial as a gas cap.

Edit: I read too fast and missed the dealer part my bad. Let us know what is going on I'm interested since the fuel pump recalls

 

What if you have the upgraded " No gascap" gascap?

 

Wait...did toyota move to the no gas cap ?

Also sorry OP welcome to tacomaworld stick around some things on here are helpful

 

Literally the only thing I like about my work truck (2018 F150) is the "no gascap" gascap. It is pretty wonderful.
Edit: Well that, and that it's free to drive. That's pretty ok too.

 

I'm pretty sure someone else in the country has had this issue and thousands have had this happen over the years. I hope we don't start posting new threads every time something happens to our vehicles. Not every vehicle will be 100%, that's why they come with a warranty. Sorry it happened, but I don't think posting a thread asking if anyone has had a check engine light occur in a new vehicle will help.

 

Update: Dealership said they received code P071015, for a transmission fluid temperature sensor “A” circuit short to battery or open. They inspected the harness and found nothing wrong and ended up clearing the code and test driving it for 30 miles and the code hadn’t reappeared. Still makes me feel little uneasy that the truck had check engine light so early on... good thing it cost me $0.00 and the light is gone so I guess thats all that matters.

 

Eh it's logged and tracked. If the issues comes back up then it'll be noted and should result in a more thorough check. With that being said enjoy

 

At least they didn't crash it during the test drive like in the other thread

 

Update #2: After 2 days of driving I’m back at the dealership for the same issue... will let ya’ll know tomorrow what they try do to fix it this time.

 

Easy fix...just pull the fuse for the check engine light

 

Its probably low on fluid like some of the 16s,17s, etc....

 

Totaled, buy back from insurance, make trail vehicle from hell.

 

TCM needs to know fluid temp for proper clutch engagement. Either harness or fluid temp sensor itself. Both will be covered under warranty and I honestly doubt any permanent damage was done unless you were seriously slamming into gear, each and every gear in which case, powertrain will cover any issues down the road.

 

its Not normal

auto or manual trans

its usually a minor oversight............like an aftermaket locking fuel cap

or the original fuel cap loose

or maybe anixious new owner................something U did

bottom line there should have been a code or codes
usually dealer will let U know what they are .........................

good luck

 

My guess issssss ..... Rodents. Let us know what they say op

 

They inspected the harness and said it was good. They also checked the trans fluid which was good as well. The dealership talked to toyota and was instructed to replace the ecu. Unfortunately for me the ecu is on back order without an eta of when it will be back in stock so until then its a waiting game.

 

So wtf are the forums for if not for seeking help amongst a handful of other things ?


Do everyone a favor. Delete your account.

 

Update #3?: Got the truck back after 2 1/2 weeks. The dealership ended up replacing the ECU along with the harness going to the transmission fluid temperature sensor. Been driving the truck for about a week and so far so good! Needless to say it sucks that this truck already had issues at less than 1000 miles but everything was covered under warranty including the rental so I’m happy with that.
