Hey guys I'm new here and I'm having some with my 03 g35 automatic
 

Hey guys,

I'm new to the g35 scene, I got my 03 g35 automatic sedan couple months ago and I haven't had any issues until last couple days.

When i I press on the gas the reva go up and the car will go no more than 10-15 and 20 mph.
I'd really need some help, if anyone has any suggestions or any fixes please let me know.
Thanks!

Get the car checked for codes as what you are experiencing is called limp mode.

What he said^

Yea im taking it to the mechanics tomorrow hopefully nothing serious,thanks!

code p0720 &p1572
 

Okay so the mechanic didn't have time for me and I ended up going to autozone see if they could get the code reader on and it gave me a code p1572 for vehicle speed sensor error and an p0720 for vehicle speed sensor revolution sensor circuit fault

now all this looks like Chinese to me can I get some suggestions other than to it to a mechanic, I'm still trying to get a hold of him

Have you done any brake or suspension work recently?

I'm having some too lolol...........

no haven't done anything yet

I would just replace the speed sensor so you don't damage the transmission
