P1130 Toyota RAV4 Code - Air/Fuel Ratio Sensor Circuit Range/Performance Malfunction Bank 1 Sensor 1

Quick Answer

The Air-Fuel ratio (A/F) sensor varies its output voltage in proportion to the air-fuel ratio. Common causes include Faulty Air fuel Ratio (A/F) Bank 1 Sensor 1, Air fuel Ratio (A/F) Bank 1 Sensor 1 harness is open or shorted, Air fuel Ratio (A/F) Bank 1 Sensor 1 circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1130 Toyota RAV4 Description

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 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.
