This code indicates that the oxygen sensor located in the exhaust manifold (bank 1, sensor 1) is not functioning properly. The oxygen sensor is responsible for measuring the amount of oxygen in the exhaust gas and sending a signal to the engine control unit (ECU) to adjust the air/fuel mixture. When the oxygen sensor is not working properly, the ECU cannot adjust the air/fuel mixture correctly, which can lead to poor performance, reduced fuel economy, and increased emissions.
Symptoms
The symptoms of a P0130 code may include:
- Check engine light
- Poor performance
- Reduced fuel economy
- Increased emissions
- Rough idle
Causes
The most common causes of a P0130 code are:
- Faulty oxygen sensor
- Damaged wiring or connectors
- Exhaust leak
Diagnosis
To diagnose a P0130 code, the following steps can be taken:
1. Check the oxygen sensor for proper operation. This can be done using a multimeter to measure the voltage output of the oxygen sensor.
2. Inspect the wiring and connectors for damage.
3. Check for exhaust leaks.
Repairs
To repair a P0130 code, the following steps can be taken:
1. Replace the oxygen sensor.
2. Repair any damaged wiring or connectors.
3. Seal any exhaust leaks.
After repairs are completed, the code should be cleared from the ECU to turn off the check engine light.
