Hey guys,


I have a 99 ES Coach Edition and the past two weeks I have seen my brake light come on the first 2 or 3 mins only in the morning and goes away the rest of the day. This evening however both the Engine light and Trac off lights came on. Is there any threads that have dealt with this issue. I have seen issues with the O2 sensor dealing with the Eng and Trac light but none with the brake light in conjunction with these.
Any suggestions would great be appreciated.


Thanks

 

Well, what codes caused the CEL to come on?

 

The code came out as a P0133 which is a dealer code. I took it to my Lexus dealer and they said it was an O2 sensor but couldn't pin point which one. As I drove the car this morning about 5 mins after I left the dealer the lights went off but they brake light is still problematic in the morning. Could that issue with the brake light pin point any of the sensors? I would have to imagine that although the engine light went off this is a first warning sign of an issue with the sensor?

 

Is the brake light the "emergency brake" or "rear brake out" light?

P0133
(DI–71)
Heated Oxygen Sensor Circuit
Slow Response
(Bank 1 Sensor 1)
 Heated oxygen sensor
 Fuel trim malfunction

 

I couldn't be certain. It's the red brake indicator light in the dash. What does this necessarily mean going forward. It doesn't sound like a critical problem however I'm sure it needs to be resolved soon I would imagine. Thanks for your help and advice

 

check the brake fluid, you may need to top it off.
it happened on my Camry a few times, after I top it off, the light went away
