I also had all three lights come on. Went to Autozone and their reader said P1155. Air fuel sensor Bank 2 sensor 1. Replaced sensor and cleared codes. Everything good. Wife drove the car that night and it spit and sputtered and 3 lights came back on. I shut it off, waited a few minutes and it drove fine. Checked codes with a buddies CarMD reader and it threw 14 codes all pointing to the mass air flow sensor. Bought a reman. MAF at autozone, installed it and hooked the hose back on the air filter assembly(?) and lights were gone. Drove the car 160 miles round trip Thanksgiving Day and lights came back on. Took car to Toyota dealer next morning and they ran codes on there computer. MAF sensor bad, a/f sensor bad, plugs misfiring. Car was running fine. Ordered new MAF sensor from Toyota. Car is parked till it comes in.
Be careful buying reman. parts from Autozone or Advance auto
