P1130 TOYOTA CAMRY – A/F Sensor Circuit Range / Performance Malfunction

Posted by

P1130 TOYOTA CAMRY Possible Causes

  • Faulty Air/Fuel Ratio (A/F) Sensor, Bank 1 Sensor 1
  • Air/Fuel Ratio (A/F) Sensor, Bank 1 Sensor 1 Circuit Open or Shorted
  • Air/Fuel Ratio (A/F) Sensor, Bank 1 Sensor 1 Circuit Poor Electrical Connection
  • Fuel Pressure
  • Fuel Injector
  • Intake Air Leaks
  • ECM

How to Fix Code P1130 TOYOTA CAMRY?

Start by checking the “Possible Causes” listed above. Visually inspect the corresponding wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector pins.

When is the Code Detected?

Code 1130 is set when the A/F sensor output voltage change value is not what the Engine Control Module (ECM) expects.

Possible Symptoms

  • Check Engine Light On (or Service Engine Soon Warning Light)

P1130 TOYOTA CAMRY Meaning

The Air/Fuel Ratio (A/F) sensor varies its output voltage proportionally 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 it to 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. 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.
