Code 21 again
 

Okay guys so originally, started with codes 21, 41, and 51......

replaced afm with new one, new oem Toyota tps and connector, and replaced with brand new Denso O2 sensor and gasket. I still get a code 21 while driving. My car only has one o2, its not a California car. Im not worried about smog I just don't want this damn code on anymore. My next step is checking the ecu, anyone have a pinout of the ecu? Also what type of reading am I looking for? (ohms, volts?)

Oh and if it helps, 86.5 NA 5 Speed....thanks guys

You sure u have it connected n no short out or broken wire cuz dat exactly happened to me on my gte

Ya its connected correctly....does anyone know what I should be reading with a multi meter? Or where too test? oh and the code is intermittent.....doesn't happen all the time

o2 sensor..

and the 02 heater sensor

since you said you just replaced your 02 sensor and all your wires are non corroded or dry rotted.. then id lean more towards the 02 heater sensor.

and 2 pages past that is.

ecu stuff

The 7M-GE's o2 sensor does not have a heater, just the 7M-GTE.

Didn't see the n/a. I guess I just assume everyone owns a turbo.

I wish I did have a turbo lol, and thanks I'll look at the resistance today. Like I said replaced a year old Denso sensor with a brand new Denso one. So idk, wire looks good. No breaks or corrosion.

Also forgot to ask. Is there maybe a difference in connectors? Im running Denso #24-1051 as per what I looked up and according to autozones website. I see another option for 24-1057 but from what I've read that's a universal fit
