Code P043E 2017 Honda CR-V Description
The P043E code for a 2017 Honda CR-V refers to the Evaporative Emission Leak Check Module Standard Pressure Low. This code indicates that there is a problem with the evaporative emission system in the vehicle. The evaporative emission system is responsible for capturing and storing fuel vapors to prevent them from escaping into the atmosphere. The system includes components such as the fuel tank, charcoal canister, purge valve, and various hoses.
Common Causes of P043E 2017 Honda CR-V
- Loose or Damaged Gas Cap: A loose or damaged gas cap can cause the system to lose pressure and trigger this code.
- Leaking Evaporative Emission System Components: A leak in any of the components of the evaporative emission system, such as hoses or the charcoal canister, can lead to a pressure drop.
- Faulty Purge Valve: A malfunctioning purge valve can cause the system to not maintain the correct pressure levels.
- Defective Evaporative Emission Leak Check Module: The module itself may be faulty and not accurately detecting pressure levels in the system.
Symptoms of P043E 2017 Honda CR-V
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the dashboard.
- Decreased Fuel Efficiency: A leak in the evaporative emission system can cause fuel vapors to escape, leading to decreased fuel efficiency.
- Strong Fuel Odor: If there is a leak in the system, you may notice a strong fuel odor coming from the vehicle.
- Failed Emissions Test: A malfunctioning evaporative emission system can cause the vehicle to fail an emissions test.
How to Fix P043E 2017 Honda CR-V
- Inspect the Gas Cap: Check the gas cap to ensure it is tightened properly and not damaged. Replace if necessary.
- Check for Leaks: Inspect all components of the evaporative emission system for leaks. Repair or replace any damaged hoses or components.
- Test the Purge Valve: Test the purge valve to ensure it is functioning correctly. Replace if necessary.
- Replace the Evaporative Emission Leak Check Module: If the module is found to be faulty, it will need to be replaced to resolve the issue.
- Clear the Code: After making the necessary repairs, clear the diagnostic trouble code from the vehicle's system using a scan tool.
Cost to Fix P043E 2017 Honda CR-V

Frequently Asked Questions about P043E 2017 Honda CR-V Code
What does the OBDII code P043E mean on a 2017 Honda CR-V?
The P043E code indicates an issue with the Evaporative Emission (EVAP) Leak Check Module, specifically that the standard pressure is lower than expected during self-testing.
What causes the P043E code on a 2017 Honda CR-V?
Common causes include a faulty EVAP Leak Check Module, damaged or disconnected EVAP system hoses, a failing fuel tank pressure sensor, or electrical issues such as damaged wiring.
What are the symptoms of a P043E code?
Symptoms may include an illuminated Check Engine Light, a slight fuel odor near the vehicle, and, in rare cases, reduced fuel efficiency or difficulty passing an emissions test.
Can I drive my 2017 Honda CR-V with a P043E code?
Yes, you can drive temporarily with this code, but it’s recommended to address the issue promptly to avoid potential fuel vapor leaks and ensure compliance with emissions standards.
How do I diagnose a P043E code on my 2017 Honda CR-V?
Start by inspecting the EVAP system hoses and connections for damage or disconnection, check the EVAP Leak Check Module for proper operation, and test the fuel tank pressure sensor using a diagnostic scan tool.
How do I fix the P043E code on a 2017 Honda CR-V?
Repairs may involve replacing a faulty EVAP Leak Check Module, repairing or replacing damaged EVAP hoses, fixing electrical wiring issues, or replacing the fuel tank pressure sensor if it's malfunctioning.
How much does it cost to repair the P043E code?
Repair costs can vary, but replacing an EVAP Leak Check Module typically costs $150–$300, while fixing hoses or wiring issues may cost less. Diagnostic fees may also apply.
Can a loose or faulty gas cap cause the P043E code?
No, a loose or faulty gas cap usually triggers other EVAP-related codes, not P043E. This code is more specific to the EVAP Leak Check Module's pressure monitoring.
Will clearing the code with a scanner fix the problem?
Clearing the code may temporarily turn off the Check Engine Light, but if the underlying issue isn’t resolved, the P043E code will likely return.
Do I need specialized tools to fix the P043E code?
Yes, diagnosing and repairing this code often requires a scan tool capable of EVAP system testing, as well as basic tools to inspect and repair hoses or wiring.
