WebMar 26, 2015 · I agree that with the O2 sensor hooked up to the ECM, you should get a swing in voltage as the ECM changes the injector pulse to accommodate lean/rich readings. But at idle, the A/F ration should be fairly constant and that is … WebIn this differential radiometer approach, the measuring sensor is screened by a hemisphere of K R S - 5 (uniformly transparent over the region l-40[i); the short-wave compensating sensor is screened by a concen- Sensing thermopile ( K R S - 5 hemisphere) and temperature indicating thermo- pile + Compensating thermo- pile (0G2 and W G 7 ...
WebJan 16, 2009 · Low HO2S voltage indicates a lean exhaust stream. If the ECM detects an HO2S voltage that stays below a specified value, DTC P0131 sets for HO2S bank 1 sensor 1, or DTC P0151 sets for HO2S bank 2 sensor 1. The heated oxygen sensor (HO2S) must reach operating temperature to provide an accurate voltage signal. WebThe O2 sensor will report to the PCM "Power Train Control Module" a lean condition with a low voltage. The PCM response would be to increase the injector pulse to drive the O2 sensor voltage high "Rich command." This CO increase would be enough for the Rhodium within the catalyst to react to cause a reduction in Nox. How about HC and Co
