P0130 Acura Code - Air/Fuel Ratio Sensor 1 Out of Range
Quick Answer
Air fuel ratio control performs fuel injection control based on the oxygen density detected in the exhaust gas in order to bring the intake mixture in the vicinity of a target air-fuel ratio. Common causes include Faulty Air/Fuel Ratio (A/F) Sensor (Sensor 1), A/F Sensor (Sensor 1) harness is open or shorted, A/F Sensor (Sensor 1) circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0130 Acura Description
This high-precision air-fuel ratio control is realized by detecting a correction value with an Air/Fuel Ratio (A/F) Sensor (Sensor 1) and then applying further correction with a secondary Heated Oxygen Sensor (Secondary HO2S) (Sensor 2).
The Powertrain Control Module (PCM) supplies a current to the A/F Sensor (Sensor 1) and monitors the current value which varies with the oxygen density in the measuring chamber of the sensor.
The current value is proportional to the air-fuel ratio, therefore the PCM can calculate the air-fuel ratio from the value of the current.
If a malfunction causes the A/F Sensor (Sensor 1) signal to the PCM to deviate from the normal control area, the A/F Sensor (Sensor 1) may still become active after the engine starts, but the air/fuel feedback does not start normally, and the emissions deteriorate. When the A/F Sensor (Sensor 1) output is out of the normal area, and this condition continues after the A/F Sensor (Sensor 1) is active, the PCM detects a malfunction and stores a Diagnostic Trouble Code (DTC).
What are the Possible Causes of the DTC P0130 Acura?
- Faulty Air/Fuel Ratio (A/F) Sensor (Sensor 1)
- A/F Sensor (Sensor 1) harness is open or shorted
- A/F Sensor (Sensor 1) circuit poor electrical connection
How to Fix the DTC P0130 Acura?
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 P0130 Acura Code
What does OBDII code P0130 mean for an Acura?
P0130 indicates that the Air/Fuel Ratio Sensor 1 (upstream sensor) is reporting values outside the expected range, affecting engine performance and efficiency.
What are the symptoms of code P0130 on an Acura?
Symptoms may include poor fuel economy, rough idle, reduced engine performance, and the check engine light being illuminated.
What causes the P0130 code on an Acura?
Common causes include a faulty air/fuel ratio sensor, damaged wiring or connectors, exhaust leaks near the upstream sensor, or issues with the engine control module (ECM).
Can I drive my Acura with a P0130 code?
While the car may still be drivable, driving with a P0130 code can lead to decreased fuel efficiency and potential damage to the catalytic converter over time.
How do I diagnose code P0130 on an Acura?
Diagnosis typically involves inspecting the air/fuel ratio sensor, checking for wiring issues, testing for exhaust leaks, and using a scan tool to monitor sensor performance.
How do I fix code P0130 on an Acura?
Fixes may include replacing the air/fuel ratio sensor, repairing or replacing damaged wiring, sealing exhaust leaks, or updating/reprogramming the ECM if necessary.
What tools do I need to repair a P0130 code on an Acura?
Common tools include an OBDII scan tool, multimeter for testing wiring, socket set for sensor removal, and exhaust sealant if leaks are present.
How much does it cost to repair a P0130 code on an Acura?
Repair costs vary but can range from $150 to $400 for parts and labor, depending on whether the sensor needs replacement or wiring repairs are required.
Can a dirty air filter cause a P0130 code on an Acura?
A dirty air filter typically does not cause this code, but it can indirectly affect air/fuel mixture and engine performance, exacerbating existing sensor issues.
Is code P0130 related to the oxygen sensor on an Acura?
Yes, the air/fuel ratio sensor is a type of oxygen sensor that monitors the air-fuel mixture in the exhaust to optimize engine performance.
