Hello,
I am new to the forums and am having trouble diagnosing these two codes. I first took it to Autozone and had them read it which recommended I replace the MAP sensor which I have, but after deleting the codes and driving again they have returned.
I have purchased an Innova 3040 RS. On the initial snapshot it shows STFT B1 0% LTFT B1 0%. STFT B2 -3.9% LTFT B2 0.8%. On live Data it shows O2S B1S1 0.0-0.800V STFT B1 S1 0-5.5%. O2S B1 S2 0.0-0.800V STFT B1 S2 99.2%. O2S B2 S1 0.0-0.800V STFT B2 S1 0-5% O2S B2S2 0.0-0.800V STFT B2 S2 99.2%. Do these readouts indicate an exhaust leak or faulty O2 sensor? Any help would be appreciated.
