Hello,

2000 Toyota Sienna LE.

When I check my Actron scanner it shows "o2s12 V" only when I check view data.
is the scanner supposed to show only this sensor or all oxygen sensors in the vehicle?

also can someone tell me what the top socket it for on this vehicle? I can't seem to fit any cig lighter type plug in there. only bottom one works.

Thanks!

Sorry for late response. the socket it not a cig lighter socket. nothing fits in there. it is smaller then cig socket.
none of my chargers fit as well.

I attached pic of sensor that is showing. code is p0171 system too lean bank 1
how many 02 sensors does this car have altogether?
I changed a sensor to aftermarket but it still does not show in scanner.
