tps probing

anyone know off-hand which two tps wires to backprobe for tps voltage? Also what are proper maf volatges for koeo & koer, if any?

For the TPS, you back probe the black wire (-), and the green wire (+). TPS voltage should be somewhere around .91-.98 volts, running any closer to 1 volt will lead to problems. Not sure about the mass air voltage off hand, I'll check after work if not answered.
