problem #1

Jan 012020

Highlander Limited 3.0L V6

  • Automatic transmission
  • 150,000 miles

At least 6 P0 codes would come up at any given time, with 3 of them repeating twice. Replacing the gas cap with cheap ones regularly usually fixed the problem. The car was about 15 years old when these codes started popping up. Never affected fuel economy.

Eventually the gas cap was no the fix, so I took it to the dealer for an inspection. There was a hose that was leaking related to the exhaust system, and a part underneath the car that broke off from the evap system. Total was around $90 for parts and labor which I thought was a steal.

Codes popped up again after around 5-10k miles, could have been a bad oxygen sensor or more rubber hoses leaking. Won't know now that the car is totaled and shipped off.
