What is the P013E error code? What is the O2 sensor delayed response – rich to poor (Bank 1 Sensor 2) fault description. How do I fix the P013E fault code What are the symptoms and causes for the P013E code fault?
What is P013A fault code? What does it stand for?
A code P013E is stored in memory if the powertrain control module, (PCM), detects that bank 1’s downstream oxygen (O2) sensor is not responding in time. The description of the code states that “Bank 1” refers to the engine bank that contains the number one cylinder. “Sensor 2,” refers to downstream sensor that follows the catalytic converter.
The proper operation of an engine is dependent on oxygen sensors (O2). These sensors can be found in the exhaust pipe or exhaust manifold. Its primary task is to determine the level of oxygen in the exhaust. The powertrain control module, or PCM, uses this information to adjust the air/fuel ratio. O2 sensors are just like other sensors and can eventually fail, causing problems.
To communicate with the PCM, oxygen sensors use electricity. These signals are dependent on the oxygen content of the exhaust. This data is used by the PCM to determine if the engine is running rich or lean. The voltage signal will decrease if there is more oxygen in the exhaust. This is a sign that the vehicle operates in a lean mixture. If the oxygen level in the exhaust is low the voltage signal will rise. This is a sign that the tool runs in a rich mixture.
To calculate the amount of fuel to be sent to the engine, the PCM uses data from an upstream oxygen sensor. To monitor the effectiveness of the catalytic convertor, it primarily uses signals from the downstream sensor.
The PCM controls the speed at which oxygen sensors react to rich-to–lean or lean–to–rich transitions. If the average response times are slower than factory specifications, fault codeP013E is issued.
The P013E fault code can affect Chevrolet (especially Cobalt), Ford and Volkswagen as well as Volkswagen, GMC/Dodge, Dodge, Chrysler, Volkswagen or Toyota.
Other fault codes could also be activated depending on the severity. These codes include P013F and P014B.
What causes the P013E fault code?
Here are some reasons why P013E should be set.
- – Defective oxygen sensor (Bank 1 Sensor 2)
- – O2 sensor circuit wiring and connector problems
- – Defective catalytic convertor
- – Leakage of the exhaust system
- – Defective PCM
What are the symptoms for P013E Trouble Code?
These symptoms may be present if you own a vehicle that has the P013E code.
- – Illumination and control of the check engine light
- – Low engine performance
- – Increased fuel consumption
- – Triggering related fault codes
How do I fix the P013E fault code?
All engine misfire codes, throttle sensor codes, mass air flow sensor codes, manifold pressure codes and throttle position sensor codes can be diagnosed and repaired. All kinds of codes can be hidden if the engine is not working properly.
- Replacing a defective oxygen sensor (Bank 1 Sens 2)
- Troubleshooting O2 sensor circuit
- – Correct reattachment
- Repair of shorted or open cables
- – Replacing the fuse in the O2 sensor heater circuit
- – Replacing PCM
- – Replacing catalytic convertor
