Code P2253 Acura Description
The P2253 diagnostic trouble code (DTC) for Acura vehicles indicates a problem with the O2 sensor negative current control circuit on bank 1, sensor 1. This sensor is responsible for monitoring the oxygen levels in the exhaust gases, providing crucial data for the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. When the negative current control circuit is reading higher than normal levels, it suggests an issue with the sensor's ability to function properly, potentially leading to inaccurate readings and inefficient engine performance.
Common Causes of P2253 Acura
- Faulty O2 sensor
- Damaged wiring or connectors
- ECM malfunction
- Exhaust system leaks
- Contaminated sensor elements
Symptoms of P2253 Acura
- Decreased fuel efficiency
- Rough idling or stalling
- Check Engine Light illuminated
- Increased emissions levels
- Reduced engine performance
How to Fix P2253 Acura
- Begin by diagnosing the specific cause of the issue using a scan tool to read the DTC and checking the sensor's wiring and connectors for damage.
- If the O2 sensor is found to be faulty, replace it with a new, OEM-quality sensor compatible with your Acura vehicle.
- Inspect and repair any damaged wiring or connectors to ensure proper connection and functioning of the sensor.
- Clear the DTC and reset the ECM to allow the system to recalibrate and monitor the O2 sensor's readings.
- Perform a test drive to verify that the issue has been resolved and that the vehicle is running smoothly with no further symptoms.
Cost to Fix P2253 Acura

Frequently Asked Questions about P2253 Acura Code
1. What does the OBDII code P2253 mean for an Acura?
P2253 indicates that the O2 Sensor Negative Current Control Circuit for Bank 1 Sensor 1 is registering a voltage or current higher than the expected range.
2. What are the common symptoms of code P2253 on an Acura?
Symptoms may include poor fuel efficiency, rough idling, reduced engine performance, and an illuminated check engine light.
3. What causes the P2253 code to appear on an Acura?
The most common causes are a faulty oxygen sensor (Bank 1 Sensor 1), damaged wiring or connectors, or issues with the engine control module (ECM).
4. Which sensor is affected by the P2253 code on an Acura?
The code refers to the upstream oxygen sensor (Sensor 1) on Bank 1, which is located before the catalytic converter.
5. Can I drive my Acura with the P2253 code?
While the car may still be drivable, it is not recommended as it can lead to poor fuel economy and potential damage to the catalytic converter over time.
6. How can I diagnose the P2253 code on an Acura?
Start by inspecting the wiring and connectors for the Bank 1 Sensor 1 oxygen sensor, then test the sensor itself using a multimeter or scan tool to check for proper operation.
7. How do I fix the P2253 code on my Acura?
Repairs may include replacing the oxygen sensor, repairing or replacing damaged wiring, or, in rare cases, reprogramming or replacing the ECM.
8. How much does it cost to repair the P2253 code on an Acura?
Replacing an oxygen sensor typically costs between $150 and $400, depending on the model and labor rates. Wiring repairs or ECM replacement may increase costs.
9. Can a dirty or clogged air filter cause the P2253 code?
While a dirty air filter can affect engine performance, it is unlikely to directly cause the P2253 code, which is specific to the oxygen sensor circuit.
10. Will clearing the P2253 code with a scan tool fix the issue?
Clearing the code may temporarily turn off the check engine light, but the underlying problem must be addressed to prevent the code from returning.
