What Does Stft B1S2 Mean. If it's switching at all, it's likely the cat isn't doing it's job. Measure resistance between bank 1 ho2s no.

3.1% for some reason when selecting stft b2 on my scanning device, it displays the above (99.2%) which. Web also, the post cat o2 should be almost rock steady if the cat is functioning correctly. The ecu's basically telling you that the catalytic. Bear in mind that while. Don't take your stft's to be a. Web what does stft b1s2 mean? Web bank 1 ho2s no. Web if the upstream sensor (b1s1) and the downstream sensor (b1s2) are both cycling identically (or nearly so) that means that catalytic convert is toast and you're going. That is because the post cat sensor (sensor 2) is not used to measure fuel trim. Measure resistance between bank 1 ho2s no.
Web to enable the correct air/fuel ratio, (stoichiometry = 14.7:1), the system uses stft to keep the system as close as possible to this figure. The 1.75 is the difference between the. Bear in mind that while. 3.1% for some reason when selecting stft b2 on my scanning device, it displays the above (99.2%) which. Web joined sep 25, 2011. In your particular case with. Presumably the readings for b1 and b2 should. They turn and adapt to the steering wheel direction and help you corner successfully. Frequency_resolution = sampling_rate / nfft; Web stft's between two banks are almost identical and are almost always positive, meaning ecu is adjusting for a lean condition. Most likely the scan tool you.
