Hai friends,

I am having a lexus rx 330 and facing probelm with Engine light, VSC and Trac off light. I taken my car to workshop and they erase the warnjng symbols through OBD. After 2 days it came again. This time the code showing in the OBD scanning is C1201 and they advised to replaced the fuel trunk cap and delete the warning signs.
Unfortunately after 2 days it came on
Can you please advise whats the possible reason for it?? 😢😢

 

I just had mine in for the same thing. Mechanic said it was the rear wheel speed sensor. I dont know why anything to do with the fuel would effect the and/traction control..
