P1133 SCION Meaning

The air-fuel ratio (A/F) sensor varies its output voltage in proportion to the air-fuel ratio. Based on the output voltage, the engine control module (ECM) determines whether the air-fuel ratio is RICH or LEAN and adjusts the stoichiometric air-fuel ratio. The ECM also checks the fuel injection volume compensation value to verify whether the A/F sensor is deteriorating or not. The deterioration of the A/F sensor response is determined by the ratio between the A/F sensor output voltage change and the fuel compensation change.
