What is code P043E?
OBD-II Code P043E is defined as a Evaporative Emission System Leak Detection Reference Orifice. The Leak Detection Pump contains a reference orifice tube. This tube restricts airflow to create a difference of pressure in the EVAP system.
How do I fix code P2419?
To solve any issue you need to follow certain steps, and to solve OBD error code P2419, you will need to undergo the following replacements:
- EVAP leak detection pump.
- EVAP purge valves.
- EVAP purge solenoids.
- EVAP pressure sensor and pump circuit wiring and connectors.
- Fuel cap and pressure sensor.
- PCM reprogramming.
Where is the evaporative emission system pressure sensor?
The EVAP Pressure Sensor, also known as a Fuel Tank Pressure (FTP) Sensor is a device that measures air pressure or vacuum in the evaporative emission (EVAP) system. This sensor is typically found on top of or inside of the fuel tank.
How do I fix error code P2402?
What repairs can fix the P2402 code?
- Replace the evaporative pump and fuse.
- Replace the evaporative pump relay.
- Repair the evaporative pump connector pins for corrosion, melted, or loose connections.
What does a code p043e mean on an OBD-II?
The PCM has detected a discrepancy in the evaporative emissions system (EVAP) leak detection reference orifice when a code P043E is stored in your OBD-II vehicle. In this case, a low flow condition has been indicated. The EVAP system is designed to capture fuel vapors (from the fuel tank) before they escape into the atmosphere.
What causes a p043e EVAP leak detection code?
Causes for this P043E engine code may include: Defective EVAP pressure sensor A damaged or clogged EVAP leak detection orifice Charcoal element (canister) ruptured Cracked or crushed EVAP or vacuum line/s
How does the p2401 Toyota EVAP system work?
P2401 Toyota Description 5 hours after the ignition switch is turned OFF, the electric vacuum pump creates negative pressure (vacuum) in the EVAP(Evaporative Emission) system. The Engine Control Module (ECM) monitors for leaks and actuator malfunctions based on the EVAPpressure. P2401 TOYOTA More Information
How to check for emission code p043f?
A diagnostic scanner, a digital volt/ohmmeter (DVOM), and a reliable vehicle information source will prove necessary for diagnosing a code P043F. Use your vehicle information source to check for technical service bulletins (TSB) that match symptoms and codes presented in the vehicle being diagnosed.
