The definition of code P013E is “O2 Sensor Delayed Response – Rich to Lean Bank 1 Sensor 2.” This means that your powertrain control module (PCM) or engine control module (ECM) has detected that the downstream oxygen sensor, also called the post-catalytic converter oxygen sensor, has indicated a delayed response time in Bank 1. You can expect to see the P013E code in various OBD-II-equipped vehicles as a generic airflow sensor code.

More About Error Code P013E
Your downstream O2 sensor monitors the amount of oxygen in the exhaust gases, a measurement that rapidly oscillates from high to low voltage due to the ECM adjusting the fuel-air mixture regularly. This data, combined with the upstream sensor at Bank 1 Sensor 1, allows your PCM to determine the efficiency of the catalytic converter and make adjustments or log codes as needed. The PCM is constantly checking the length of time that it takes for the sensor in question to respond to rich-to-lean and lean-to-rich transitions, and this O2 sensor code indicates that the response time for the rich-to-lean transition in Bank 1 is slower than your specific vehicle’s factory specifications.

What Are the Symptoms of a P013E Code?
The core problem of the P013E diagnostic trouble code will mainly impact its common symptoms. Most of the time, you’ll see other DTCs on top of this one, so the symptoms of those engine codes will likely be most of what makes up your symptoms. However, in association with the P013E code, you’re likely to see general poor engine performance and issues with fuel efficiency. You should also expect the check engine light or other driver information warning light to turn on with these codes.
What Are Some Causes of a P013E Code?
The most common cause of the code P013E error is usually a blown fuse or burnt fuse somewhere in the system. However, other causes include issues with a defective sensor, wiring issues, exhaust leaks in the engine, and other problems resulting in the engine’s fuel mixture creating either lean or rich faults. In rare cases, this code may be due to a problem like a faulty catalytic converter or failed PCM, although these are uncommon. Most of the time, you’ll need to check for other error codes to determine the core cause of this code, as it’s not common to see it by itself.
How Serious Is the P013E Code?
The P013E code should be treated as quite serious, primarily because it can indicate other problems associated with the engine. This code doesn’t often show up by itself, which means that you’ll probably be experiencing a different issue that’s accompanied by this code. Since this code doesn’t give you much insight into the core problem within the vehicle, and the problem itself could be very severe, it’s best to treat it as though it is very serious.
Can I Still Drive with a P013E Code?
Most of the time, you’ll physically be able to drive with the P013E code. It’s very uncommon to see the P013E code cause severe drivability problems. However, because you don’t know the underlying cause of the P013E code, it’s still best to avoid driving when it’s active. You just don’t know if it’s a code that might cause damage to your engine or a dangerous driving condition. Plus, the problems with fuel economy can make it more expensive to run, as higher fuel consumption results in having to refuel more frequently.
How Easy Is It to Diagnose a P013E Code?
The diagnostic process for a P013E code will almost inevitably require you to use a diagnostic scanner and take diagnosis time to look at the other codes the vehicle has logged. It’s very rare to see this code all by itself, which means that the diagnostic process may be very simple or very complex, depending on the other codes also appearing. If you’re not well-versed in checking out fault codes and using them to pursue a fix, it’s a good idea to talk to a certified mechanic.
How Difficult Is It to Inspect a P013E Code?
Inspecting the P013E code is often equally complex as diagnosing it. This is because you usually won’t know the problem until you start looking at other response trouble codes within the vehicle. If you’re experiencing the P013E code, inspection will start with a code scanner, but it’ll also require information such as technical service bulletins, wiring guides, and vehicle repair guides. If you don’t have access to that information or are uncomfortable going through all this hassle, a professional mechanic may be your best option.
Need Additional Help with Your P013E Code?
It’s common for people to request help with the P013E code, as this code can often be quite difficult to inspect and diagnose for DIYers. Here’s how you can get that help.
First, you should find an auto repair shop in your area. A local auto repair shop can give you the steps necessary for successful repairs without being too far out of the way.
Additionally, it’s a good idea to check out the OBD-II database at KBB.com. This code will almost always be a secondary component of additional codes, and the OBD-II database will give you more insight into those codes.
