How do I fix code P1130 LEXUS
Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.
Cost of diagnosing the P1130 LEXUS code
Labor: 1.0The cost of diagnosing the P1130 LEXUS code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.
When is the P1130 LEXUS code detected?The 1130 code is set when A/F sensor output voltage change value is not what the Engine Control Module (ECM) is expecting.
P1130 LEXUS Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P1130 LEXUS MeaningThe 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.
