Permit me to mooch off of this group's experience. My dad's 2000 Tundra is giving a code for O2 sensor heater fault in Bank #2 Sensor #1. I have read that Bank 1 is the bank containing cylinder #1, but I can not determine which is cylinder no.1 on the 4.7. Is it on the driver's or passenger side?
( If a diagram is on the under hood sticker, please understand that I have been trying to help my dad over the phone, and I do not have access to the truck.)
Any help is appreciated.
Scott
