Hi! I have a 2019 Lexus is300 fsport. I’ve been the only owner and I work from home so it only has 40k miles. In the time span of a year, my check engine light has came on 4 times with code p013a00.

Last December, they replaced one of the o2 sensors and the light came back a month later so they replaced the same sensor since the one from December was defective.

Fast forward to last week - light comes on again. Lexus ran different tests and everything passed. They cannot find a cause or reason for the light to be on so they turned it off in hopes that it’s just a fluke and opened a case to inquire about any known problems.

It came back on yesterday 😩😩😩 has anyone else experienced the same issue? I’m not sure what I’m supposed to do and I’m pregnant so I’m getting tired of dealing with this especially when the car is in such great condition otherwise.

 

Did they check for leaks? Try add some fuel additive when you fill up next time maybe it burn cleaner for the sensor.

 

thats a good point about adding some fuel additive! I’m not sure what they checked truthfully, they just said they ran multiple inspections/tests and did a test drive. My car is back with them so let’s see what they say this week 😭
