The P1457 code on a Honda Civic is related to the evaporative emission (EVAP) system. The EVAP system is responsible for capturing and storing fuel vapors from the gas tank and then delivering them to the engine for combustion. The P1457 code indicates that there is a problem with the EVAP system’s control circuit.
P1457 code on a Honda Civic
There are several possible causes for the P1457 code on a Honda Civic, including a faulty EVAP canister vent shut valve, a leak in the EVAP system, a clogged charcoal canister, or a problem with the fuel tank pressure sensor.
Additionally, the problem may be caused by a damaged or loose gas cap or a disconnected hose in the EVAP system.
To diagnose the problem, a mechanic will typically start by checking the gas cap and inspecting the EVAP system for any obvious signs of damage or leaks. They may also use a smoke machine to detect any leaks in the system. Once the problem is identified, the mechanic will replace or repair the faulty component to fix the issue.
It’s important to address the P1457 code as soon as possible, as it can cause increased emissions and reduced fuel efficiency. Additionally, if the problem is not fixed, it can cause damage to other components in the EVAP system.

P1457 code on a Honda Civic possible symptoms and solutions
Table: P1457 code on a Honda Civic possible symptoms and solutions for them
| Symptom | Potential Solution |
|---|---|
| Check Engine Light | If the check engine light is illuminated, it’s important to diagnose and fix the problem as soon as possible. A qualified mechanic can use a diagnostic tool to read the error code and identify the underlying issue. |
| Reduced fuel efficiency | The P1457 code can cause increased emissions and reduced fuel efficiency. Fixing the problem can help restore the car’s performance and fuel efficiency. |
| Fuel odor | If there is a fuel odor coming from the car, it may indicate a leak in the EVAP system. The system should be inspected for leaks and any damaged or worn components should be replaced. |
| Hard starting | A problem with the EVAP system can cause the engine to be harder to start. Fixing the problem can help ensure reliable starting and operation of the car. |
| Rough idle | A problem with the EVAP system can also cause rough idle. Fixing the problem can help restore smooth and consistent engine operation. |
It’s worth noting that not all of these symptoms may be present in every case of the P1457 code, and a thorough diagnosis by a qualified mechanic is typically required to identify the specific symptoms and underlying problem.
P1457 code on a Honda Civic Description
The P1457 code on a Honda Civic indicates a problem with the car’s evaporative emission (EVAP) system, which is responsible for capturing and storing fuel vapors from the gas tank and then delivering them to the engine for combustion.
The code specifically indicates a malfunction in the control circuit of the EVAP system. This could be caused by a variety of issues, including a faulty EVAP canister vent shut valve, a leak in the EVAP system, a clogged charcoal canister, a problem with the fuel tank pressure sensor, a damaged or loose gas cap, or a disconnected hose in the EVAP system.
When the P1457 code is triggered, the car’s engine control module (ECM) will store a diagnostic trouble code (DTC) and illuminate the check engine light. In addition, the car may exhibit symptoms such as increased emissions, reduced fuel efficiency, fuel odor, hard starting, or rough idle.
To diagnose and fix the problem, a qualified mechanic will typically inspect the EVAP system for damage or leaks and use a diagnostic tool to read the error code and identify the specific issue. Once the problem is identified, the mechanic will replace or repair the faulty component to fix the issue.
It’s important to address the P1457 code as soon as possible, as it can cause increased emissions, reduced fuel efficiency, and other issues if left unaddressed. Regular maintenance of the EVAP system, including checking the gas cap for tightness and inspecting hoses for damage, can help prevent the P1457 code from occurring.
How much does it cost to diagnose and fix the P1457 code on a Honda Civic?
The cost to diagnose and fix the P1457 code on a Honda Civic can vary depending on several factors, including the cause of the issue, the extent of the repairs needed, and the labor rates in your area.
If the problem is relatively simple, such as a loose gas cap or a disconnected hose, the cost to diagnose and fix the issue may be relatively low, typically ranging from $50 to $200.
However, if the problem is more complex, such as a faulty EVAP canister vent shut valve or a leak in the EVAP system, the cost to diagnose and repair the issue could be higher. In such cases, the cost could range from $200 to $500 or more.
It’s important to note that these are just estimates, and the actual cost could be higher or lower depending on the specific circumstances. To get an accurate estimate of the cost to diagnose and fix the P1457 code on your Honda Civic, it’s best to take it to a qualified mechanic for an inspection and estimate.
How to fix the P1457 code on a Honda Civic?
The steps to fix the P1457 code on a Honda Civic will vary depending on the underlying issue causing the code to be triggered. Here are some general steps that a mechanic may take to fix the problem:
- Inspect the EVAP system: The mechanic will visually inspect the EVAP system for any signs of damage or leaks. They may also use a smoke machine to detect any leaks in the system.
- Check the gas cap: If the gas cap is loose, damaged, or missing, the mechanic will replace it with a new one.
- Inspect the EVAP canister vent shut valve: If the EVAP canister vent shut valve is faulty, the mechanic will replace it with a new one.
