Re: 2006 Highlander P0420

Today I got my daughter to come by so I could change out the Post O2 sensor, she was two weeks behind in her laundry.

I also scanned first and the following set when code happened
Fuel Sys1 CL
Fuel Sys2 NA
Calc Load% 49.8
ECT F 187
STFT B1% 3.1
LTFT B1% 0.0
Eng RPM 1748
Vec Mph 39
Spark Adv 33.0
IAT Degree F 82
MAF Lbs/Min 1,0
TPS% 19.6

Honestly I cant tell you what most of it means but if O2 sensor doesn't cure it I will be learning. I will post again what happens. Hard to get college students to talk to except when payments are due.
