Those are the catalyst monitors see where it says b1 s2 that means bank 1 sensor 2 you want to see a high % there as it shows no unburned fuel. Web joined sep 25, 2011. Web stft is the direct result of the feedback that the oxygen or air/fuel ratio sensors are providing to the pcm. 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. The ecu's basically telling you that the catalytic. Web bank 1 ho2s no. If it's switching at all, it's likely the cat isn't doing it's job. Web stft b1s2 means short term fuel trim bank 1 sensor 2, which is the downstream 02 sensor from the catalytic converter. Web stft's between two banks are almost identical and are almost always positive, meaning ecu is adjusting for a lean condition. Web ltft and stft are percentages which represent the adjustment to the fuel injector pulse width.
Web what does stft b1s2 mean? Web bank 1 ho2s no. The ecu's basically telling you that the catalytic. 3.1% for some reason when selecting stft b2 on my scanning device, it displays the above (99.2%) which. A p0136 b1s2 means that the sensor located behind the catalytic converter is having this. #3 · oct 26, 2015. 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. Web joined sep 25, 2011. 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. 1 is located in the left exhause pipe before catalytic convertor.
