When is the code detected?The P2A03 Code is set when A/F sensor output voltage change value is below regular value against fuel trim change value.
- Engine Light ON (or Service Engine Soon Warning Light)
P2a03 2009 Toyota Camry DescriptionThe Air-Fuel ratio (A/F) sensor varies its output voltage in proportion to the air-fuel ratio. Based on the output voltage, the ECM determines if 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 check if the A/F sensor is deteriorating or not. A/F sensor response deterioration is determined by the ratio of the A/F sensor output voltage variation and fuel trim variation.
