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. Web too much voltage can cause components to overheat and potentially suffer damage. Web srf in subaru means steering responsive fog lights. Web you haven't provided how you calculated the frequency resolution, but here is what it should be: Web stft (short term fuel trim) and ltft (long term fuel trim) at times i have seen stft vary from 0 to 25%. Bear in mind that while. Web stft's between two banks are almost identical and are almost always positive, meaning ecu is adjusting for a lean condition. Web bank 1 ho2s no. Web stft b1s2 means short term fuel trim bank 1 sensor 2, which is the downstream 02 sensor from the catalytic converter.
Asked jan 5, 2017 by scott. Presumably the readings for b1 and b2 should. 1 is located in the left exhause pipe before catalytic convertor. If it's switching at all, it's likely the cat isn't doing it's job. Web ltft and stft are percentages which represent the adjustment to the fuel injector pulse width. 3.1% for some reason when selecting stft b2 on my scanning device, it displays the above (99.2%) which. Bear in mind that while. The 1.75 is the difference between the. Measure resistance between bank 1 ho2s no. Web bank 1 ho2s no. Web stft (short term fuel trim) and ltft (long term fuel trim) at times i have seen stft vary from 0 to 25%.
