P1137 BUICK Meaning

To control emissions, a catalytic converter converts harmful exhaust emissions into harmless water vapor and carbon dioxide. The Powertrain Control Module (PCM) can monitor this process using a Heated Oxygen Sensor 2 (HO2S 2). The HO2S 2, located in the exhaust stream beyond the catalytic converter, produces an output signal that indicates the catalyst’s storage capacity. This signal indicates the catalyst’s ability to effectively convert exhaust emissions. If the catalyst is functioning properly, the HO2S 2 signal will be much less active than the signal produced by the Front Heated Oxygen Sensor 1 (HO2S 1).

P1137 CHEVROLET Meaning

To control emissions, a catalytic converter converts harmful exhaust gas emissions into harmless water vapor and carbon dioxide. The Powertrain Control Module (PCM) can monitor this process using a Heated Oxygen Sensor 2 (HO2S 2).

P1137 FORD Meaning

The Heated Oxygen Sensor 2 (HO2S2) (downstream), after the three-way catalyst (manifold), monitors the oxygen level in the exhaust gases on each bank. For optimal catalyst operation, the air-fuel mixture (air-fuel ratio) must remain close to the ideal stoichiometric ratio. The HO2S2 output voltage changes abruptly near the stoichiometric ratio. The Powertrain Control Module (PCM) adjusts the fuel injection time so that the air-fuel ratio is nearly stoichiometric. The HO2S2 generates a voltage between 0.1 and 0.9 V in response to oxygen in the exhaust gases. If oxygen in the exhaust gases increases, the air-fuel ratio becomes lean. The PCM interprets Lean when the HO2S2 voltage is below 0.45 V. If oxygen in the exhaust gases decreases, the air-fuel ratio becomes rich. The PCM interprets Rich when the HO2S2 voltage is above 0.45 V.
