This code means that the car's computer is having trouble with one of the oxygen sensors. These sensors help the car know how much fuel to use. It's like when you can't figure out how much sugar to put in your lemonade because your measuring cup is broken.
The P0162 code indicates a problem with the oxygen sensor circuit on the third sensor of the second bank of the engine. This sensor helps monitor the efficiency of the catalytic converter.
The OBD-II code P0162 is triggered when the Engine Control Module (ECM) detects a malfunction in the oxygen sensor circuit for Bank 2 Sensor 3. This sensor is responsible for measuring the amount of oxygen in the exhaust gases after they pass through the catalytic converter, ensuring the engine is running efficiently and emissions are minimized.
• Check Engine Light illuminated
• Increased fuel consumption
• Poor engine performance
• Faulty oxygen sensor
• Wiring issues or poor connections in the O2 sensor circuit
• Exhaust leaks affecting sensor readings
Oxygen Sensor: A device that measures the amount of oxygen in the exhaust gases.
Catalytic Converter: A component that reduces harmful emissions from the engine.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for Bank 2 Sensor 3.
• Test the oxygen sensor for proper operation.
• Replace the faulty oxygen sensor.
• Repair or replace damaged wiring or connectors.
• Fix any exhaust leaks.
• OBD-II scanner
• Multimeter
• Wrench set

Moderate
• Toyota Camry
• Ford F-150
• Chevrolet Silverado
• Regularly inspect and maintain oxygen sensors.
• Ensure exhaust system is free of leaks.
• Keep up with scheduled vehicle maintenance.
Sensor Issue
• Address the issue promptly to avoid reduced fuel efficiency.
• Consult a professional mechanic if unsure about repairs.
Oxygen sensors may be covered under emissions warranty, typically up to 8 years or 80,000 miles.
Oxygen sensor issues are common in vehicles with high mileage or those that have not been regularly maintained.
Moderate – Should be addressed soon to prevent further issues.
Ignoring this code can lead to increased emissions, which may not comply with local environmental regulations.
• Engine at operating temperature
• Vehicle in closed-loop mode
The oxygen sensor is located in the exhaust system, typically after the catalytic converter on Bank 2.
Q: Can I drive with a P0162 code?
A: While you can drive with this code, it's best to fix it soon to avoid increased fuel consumption and emissions.
Q: How do I know which sensor is Bank 2 Sensor 3?
A: Bank 2 refers to the side of the engine with cylinder 2. Sensor 3 is usually located after the catalytic converter on this bank.

Fitment Required · Vehicle-fitment part
Relevant when catalyst-efficiency or emissions faults persist after proper diagnosis.
Catalyst-efficiency faults sometimes point toward converter problems after proper testing.
Catalytic converters are highly vehicle-specific and should not be purchased by code alone.
View options on AmazonThese parts may be related to this fault category, but a code by itself does not confirm exact fitment or guarantee that replacing a part will solve the problem.
