P2195 2010 Toyota Camry Code - Oxygen Air/Fuel Sensor Signal Stuck Lean 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 P2195 2010 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 P2195 2010 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)
How to Fix the DTC P2195 2010 Toyota Camry?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?

Frequently Asked Questions about P2195 2010 Toyota Camry Code
What does OBDII code P2195 mean for a 2010 Toyota Camry?
P2195 indicates that the oxygen or air/fuel ratio sensor (Bank 1 Sensor 1) is reporting a "stuck lean" condition, meaning the air-fuel mixture is too lean for proper combustion.
What are the symptoms of code P2195 in a 2010 Toyota Camry?
Symptoms include poor fuel economy, rough idling, hesitation during acceleration, potential engine misfires, and an illuminated Check Engine Light.
What causes a P2195 code in a 2010 Toyota Camry?
Common causes include a faulty air/fuel ratio sensor, vacuum leaks, exhaust leaks, dirty fuel injectors, or issues with the engine control module (ECM).
Can a dirty air filter cause a P2195 code?
Yes, a clogged or dirty air filter can restrict airflow, which may lead to a lean condition and trigger the P2195 code.
How do you diagnose a P2195 code?
Diagnosis involves checking for vacuum or exhaust leaks, testing the air/fuel ratio sensor, inspecting wiring and connectors, and using a scan tool to monitor sensor data and fuel trim levels.
Can you drive with a P2195 code?
Driving with a P2195 code is not recommended as it can lead to reduced performance, increased emissions, and potential engine damage if left unresolved.
How much does it cost to fix a P2195 code in a Toyota Camry?
Repair costs vary but can range from $150 to $400 depending on whether the issue is a faulty sensor, vacuum leak, or another related problem.
What is Bank 1 Sensor 1 in a 2010 Toyota Camry?
Bank 1 Sensor 1 refers to the upstream oxygen or air/fuel ratio sensor located before the catalytic converter on the side of the engine with cylinder 1.
Can a bad fuel injector cause the P2195 code?
Yes, a clogged or malfunctioning fuel injector can reduce fuel delivery, resulting in a lean condition and triggering the P2195 code.
What tools are needed to fix a P2195 code?
Common tools include a scan tool or code reader, a multimeter for testing the sensor, and basic hand tools to inspect and replace components like sensors or hoses.
