I just did oil change and brakes changed for my RX300&2001 Lexus yesterday at Tire Plus, but today the engine check light comes out, i went to auto zone for checking , the code is P0174, then i went to tire plus for fixing the problem, but guy who work at tire plus said the problem is sensor, they said it would cost me around $1500 to replace it, if let the problem on, car can't pass the emission test, so i have to replace it. I refused it. then they said they already turn the light off.
right now, do i need to pay $1500 to change it ? whether the engine check light comes out again?
