Asked by CPE11 Aug 16, 2015 at 11:55 AM about the 2002 Toyota Highlander Limited V6 4WD

Question type: Maintenance & Repair

I have a 2002 Highlander w/ 112K miles on it. Don't want to put huge $$$ into it, but
noticed the VSC and Engine Lights come on and stay on. Correspondingly, I have also
recently noticed a resonating sound coming from the under carriage of my Highlander.  
It sounds like an exhaust system leak. So, per recommendation of the Gurus, I had
the codes scanned and it came up "p0136 - (Bank 1) Rear oxygen sensor
malfunction". Could these two issues be related?  Is this an expensive repair?  
Thanks!

This is an issue with Toyota, ESP. after maintenance is done. I replaced spark plugs in my 04 highlander limited v6, two mins after startup, check engine + VSC lights came on. same thing with my moms 00 Avalon. Usually an 02 sensor. Toyota should be addressing this issue, but they don't!
