Diagnosing a CEL w/ a factory Toyota OBD II CAN reader. The problem turned out to be a common problem with these model of Toyota Tundraz. It was a faulty air/fuel sensor. Emissions related stuff. My 1st upload. Certified Toyota technician with the right equipment for the right job.
Wont do a video on replacing the sensor but just buy this air fuel ratio sensor at Amazon and replace the old one. It is drum roll Denso 234-9001 Oxygen Sensor (Air and Fuel Ratio Sensor). Good luck.
