Tonight, during a short ride, all the sudden the VSC TRAC, VSC OFF and Check Engine came on. Atfter home, I got the P0057 code from a OBDII scanner. The P0057 code indicates O2 sensor on bank 2 lower sensor. However, the interesting thing is I also lost the power seat adjustment on the seat memory. When I switched between L1 and L2 , the mirrors and the steering position changes and the seat did not. However, the adjustment buttons on the seat itself work correctly. I wonder if this problem associates with P0057? Anyone has the same issue?

 

I have a similar issue. O2 code, check engine light n both VSC lights but wit L1 n L2. Nothing changes.

 

O Ya. Mine is a 04 GS300

 

Standard stuff I think -- Check for a blown fuse. Check for a weak battery. Check for a disconnected O2 sensor wire. Check that the catalyst isn't turning cherry red from heat.

Thanks for the comments.
Re-set the seat memory L1 & L2 today. It worked normally. It was weird to lose the seat position, but not the side mirror's and the steering column's yesterday. Ordered the O2 sensor today and waiting to see if it will fix the issue.

 

Which fuses do you check for P0057 on a 07 ES350?

 

Sorry, no idea. Try asking in the ES forum.
