What is the P0130 fault code What is the O2 Sensor Circuit Bank 1, Sensor 1 failure description? How do I fix the P0130 fault code What are the symptoms and causes for the P0130 fault code
What is the P0130 Fault code? What does it all mean?
The oxygen sensor, also known as O2 sensor, plays an important role in vehicle exhaust systems. It measures the oxygen level in the exhaust gases from the engine and produces a voltage signal that corresponds to this oxygen content. The voltage signal is between 0.1 and 0.9 volts. The voltage signal ranges from 0.1 to 0.9 volts. A value of 0.9V means that the engine runs in a rich mixture. This voltage signal is used by the control module to determine how much fuel to inject while it is closed loop. When the powertrain control module (PCM/ECM detects an issue with 1 of the oxygen sensors or circuits, a code P0130 will be triggered. The PCM will store a fault code P0130 if it receives a low voltage signal (less than 0.4% volts) from the oxygen sensor for more than 20 seconds (depending on which model).
This fault code’s sensor is located at the first sensor side by the number 1 cylinder.
Some vehicles are more susceptible to P0130 than others. You are most likely to get the P0130 fault code if you own a Ford, especially Ford F-150, Nissan, Audi or BMW.
This fault code will cause the check-engine light to turn on, increase fuel consumption, and cause the PCM’s engine management strategies to be changed.
What is the P0130 Fault Code and Why Does It Happen?
As with many OBD-II fault code codes, P0130 may be triggered by a variety reasons. Below are the most common reasons this code might appear.
- – Defective O2 sensor / air-fuel ratio (AFR) sensor
- – Defective O2 sensor / air-fuel ratio sensor heater circuit
- – Circuit or sensor problem due to defective, burned, or damaged wiring.
- – Connectors that are loose, wet, or corroded
- – Low fuel pressure issues
- – Leakage of air at the intake inlet
- – Exhaust system leaks
- – Leakage in the fuel or air system
- – The engine can operate in either a rich or lean environment
- – Sensor to detect defective mass airflow (MAF)
- – Defective manifold absolute Pressure (MAP), sensor
- – Leakage in the EVAP System
- – Leaky fuel pressure regulator
- – PCM related problems (e.g. Faulty, obsolete software, etc.
What are the symptoms of the P0130 Fault code?
You may experience many symptoms with the P0130 code, or none at all. The most common symptoms include:
- – Illumination at the check engine lights
- – Vehicle idling irregularly
- Engine stalling in certain cases
- – Exhaust smoke – White or black
- – Increased fuel consumption
How do I fix the P0130 fault code?
It can take time to find the cause of the P0130 code. Sensor issues can be intermittent or continuous. Sometimes the solution is very easy, but sometimes it takes a long time.
To detect leaks, spray the engine and vacuum lines with leak detection spray. While the spray is being applied, monitor the engine RPM and oxygen sensor values. If there is an area of sprayed water that is not properly drained, speed and sensor values may change.
- Road testing is necessary to determine if codes will be returned.
- – Data from PCM should not be ignored.
- All the damaged cables and connections should be checked.
- Check for leaks in the vehicle’s intake or exhaust system.
- – Defective parts must be replaced
How serious is the P0130 Fault code?
Fault code 0130 does not usually affect vehicle operation. However, it can increase exhaust emissions and fuel use, which can lead to a fuel imbalance, which can damage the engine, and a costly catalytic convert repair. It is highly recommended that the fault should be identified and fixed as soon as possible.
