Code P2297 Description
The P2297 diagnostic trouble code indicates that the oxygen sensor on Bank 1, Sensor 1 is reading out of range during deceleration. This sensor is responsible for measuring the oxygen content in the exhaust gases as they leave the combustion chamber. The data collected by the oxygen sensor is crucial for the engine control module (ECM) to adjust the air-fuel ratio for optimal combustion efficiency.
Common Causes of P2297
- Faulty oxygen sensor
- Wiring or connector issues
- Vacuum leaks
- Exhaust system leaks
- Malfunctioning ECM
Symptoms of P2297
- Decreased fuel efficiency
- Rough idling
- Hesitation during acceleration
- Engine misfires
- Increased emissions
How to Fix P2297
- Perform a visual inspection of the oxygen sensor, wiring, and connectors for any visible damage or corrosion.
- Use a scan tool to monitor the oxygen sensor's voltage output and compare it to specifications during deceleration.
- Replace the oxygen sensor if it is found to be out of range or faulty.
- Repair any wiring or connector issues if necessary.
- Clear the diagnostic trouble codes and perform a test drive to verify that the issue has been resolved.
Cost to Fix P2297
The cost of repairing a P2297 diagnostic trouble code can vary depending on the specific cause of the issue and the cost of parts and labor in your area. On average, replacing an oxygen sensor can cost between $100 and $300, while addressing wiring or connector issues may add additional labor costs. It is advisable to consult with a professional mechanic or auto repair shop to get a more accurate estimate based on your vehicle's make and model.

Discuss the causes and fixes for P2297 OBDII Code

just realized that the exhaust was leaking next to the oxygen sensor.
-
Thank you for letting us know. Exhaust leak will definitely alter the O2 sensor readings.
-
I have replaced both oxygen sensors on my 2020 Nissan versa s and code p0171, p0101, and p2297 is popping up. I also replaced the plugs and #4 coil. and engine is still on!

When you have P0171 (lean), P0101 (MAF performance), and P2297 (front O2 out of range on decel) all showing up together, that almost always means the engine is still getting unmetered air or the MAF is giving the ECM bad information. Replacing O2 sensors won’t fix these codes because the O2 sensors are only reporting the problem, not causing it.
On the 2020 Versa, the most common causes for this cluster of codes are:
1. Intake or vacuum leak
A torn intake boot, loose clamp, cracked PCV hose, or small vacuum leak will make the engine run lean and confuse the MAF. This alone can set all three codes.2. Dirty or failing MAF sensor
Even if it looks clean, the film inside can get contaminated. A bad MAF on these cars is very common. Cleaning sometimes helps, but many need replacement.3. Exhaust leak before the front O2 sensor
A tiny leak at the manifold or flex pipe can pull in fresh air and make the O2 sensor read lean, especially on deceleration.4. Low fuel pressure
Weak pump or clogged filter can cause a lean condition under load, which triggers P0171 and P2297. Less common, but worth checking if the other items look good.5. Aftermarket or improperly installed air filter / intake
Anything that changes airflow without being calibrated can cause P0101 and lean codes.Since you’ve already replaced sensors and ignition parts, focus on:
• Checking the intake boot from the airbox to the throttle body for cracks
• Verifying no vacuum leaks around PCV hoses
• Inspecting the exhaust manifold and flex pipe for leaks
• Cleaning or replacing the MAF sensor (use MAF cleaner only)
• Looking at fuel trims with a scan tool — that will point you in the right directionOnce the actual airflow or fueling issue is corrected, all three codes should clear and stay off.
