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 |
