P2196 2007 Toyota Camry Code - Oxygen Air/Fuel Sensor Signal Stuck Rich Bank 1 Sensor 1
Quick Answer
The Air-Fuel ratio (A/F) sensor provides output voltage approximately equal to the existing air-fuel ratio. Common causes include Faulty Oxygen Air/Fuel Sensor Bank 1 Sensor 1, Oxygen Air/Fuel Sensor Bank 1 Sensor 1 harness is open or shorted, Oxygen Air/Fuel Sensor Bank 1 Sensor 1 circuit poor electrical connection. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P2196 2007 Toyota Camry Description
The A/F sensor output voltage is used to provide feedback for the Engine Control Module (ECM) to control the air-fuel ratio.
With the A/F sensor output, the ECM can determine deviation from the stoichiometric air-fuel ratio and control proper injection time. If the A/F sensor is malfunctioning, the ECM is unable to accurately control air-fuel ratio.
The A/F sensor is equipped with a heater which heats the zirconia element. The heater is also controlled by the ECM. When the intake air volume is low (the temperature of the exhaust gas is low), current flows to the heater which heats the sensor to facilitate detection of accurate oxygen concentration.
The A/F sensor is a planar type. Compared to a conventional type, the sensor and heater portions are narrower. Because the heat of the heater is conducted through the alumina to zirconia (of the sensor portion), sensor activation is accelerated.
What are the Possible Causes of the DTC P2196 2007 Toyota Camry?
- Faulty Oxygen Air/Fuel Sensor Bank 1 Sensor 1
- Oxygen Air/Fuel Sensor Bank 1 Sensor 1 harness is open or shorted
- Oxygen Air/Fuel Sensor Bank 1 Sensor 1 circuit poor electrical connection
- Faulty EFI Relay
- Faulty Injector
- Faulty Engine Control Module (ECM)
