This summary uses the existing diagnostic information shown in full below.
This code means that one of the car's oxygen sensors, which helps control how much fuel the engine uses, is not working right when the car slows down.
The oxygen sensor measures the amount of oxygen in the exhaust gases. If it detects a value that is out of the expected range during deceleration, this code is triggered.
P2298 indicates that the upstream oxygen sensor on bank 2 is reporting a voltage that is outside the normal range during deceleration. This could affect the air-fuel mixture, leading to engine performance issues.
• Check Engine Light is on
• Poor fuel economy
• Rough idling
• Faulty oxygen sensor
• Exhaust leak
• Fuel system issues
Oxygen Sensor: A device that measures the amount of oxygen in the exhaust gases.
Bank 2: The side of the engine opposite to bank 1, usually the side without cylinder 1.
• Use an OBD-II scanner to confirm the code.
• Inspect the oxygen sensor and wiring for damage.
• Check for exhaust leaks.
• Replace the faulty oxygen sensor.
• Repair any exhaust leaks.
• Ensure proper fuel system operation.
• OBD-II scanner
• Wrench set
• Multimeter
$150 - $300
Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly inspect oxygen sensors.
• Maintain the exhaust system.
• Use high-quality fuel.
Sensor Issue
• Have the vehicle inspected by a professional.
• Do not ignore the Check Engine Light.
Oxygen sensors may be covered under the vehicle's emissions warranty.
This code has been common in vehicles with aging oxygen sensors or exhaust system issues.
Moderate – It should be addressed soon to prevent further engine issues.
Driving with a faulty oxygen sensor can lead to increased emissions and may not pass emissions testing.
• Vehicle must be decelerating.
• Engine must be at operating temperature.
The oxygen sensor is located in the exhaust system, upstream of the catalytic converter on bank 2.
Q: Can I drive with a P2298 code?
A: It's possible, but not recommended as it can lead to poor fuel economy and increased emissions.
Q: How do I know if my oxygen sensor is bad?
A: Common signs include a Check Engine Light, poor fuel economy, and rough idling.
Budget · Enhanced code reader
A wired color-screen reader with readiness hotkeys, live data, code definitions, and data logging.
Good for emissions-related codes because it exposes readiness monitors and live powertrain data.

Specialty · O2 sensor socket
Helpful when the code points toward exhaust or oxygen-sensor work and space is tight.
Useful when the diagnosis points toward oxygen-sensor removal or replacement.

Fitment Required · Vehicle-fitment part
Relevant when the code or supporting diagnostics point toward upstream or downstream oxygen-sensor faults.
This code family often involves upstream or downstream oxygen-sensor diagnosis.
Verify exact sensor position and vehicle fitment before buying.

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.
