P043E 2017 Honda CR-V Code - Evaporative Emission Leak Check Module Standard Pressure Low
Quick Answer
The Powertrain Control Module (PCM) starts the Evaporative Emission (EVAP) system diagnosis after the vehicle has been turned to the OFF (LOCK) mode and has met all other enable conditions (initial engine coolant temperature and off for at least 5 hours). Common causes include Faulty Vacuum Pump, Faulty Vacuum Pump (Motor), Faulty Control Valve. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

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.
