Hi,

This light just came on tonight.

In the owner's manual, it says this maybe caused by an empty gas tank or a loose/absent gas cap. But that is not the case. The manual also states that if those reasons are not the case it maybe a transmission or electrical issue and to see a Lexus dealer immediately.

Does anyone have any advice?

Thanks, Chris

yup, definitely replace that first before you go any further

 

Thank you both, I will definitely try that first. The mechanic today said I needed a new mass airflow sensor ($475) plus labor and some $129 3in1 deal that cleans the injectors, air filter and something else.

 

maf huh? sheesh i highly doubt that is ur problem
