How do I fix error code p1409?
The code 1409 in most case is set due to a bad EGR control solenoid. Replacing the defective EGR control solenoid will likely correct your concern. To remove the EGR valve, you should first remove battery ground cable. Then, disconnect the EGR vacuum regulator valve.
What is a EGR vacuum regulator solenoid?
The EGR vacuum regulator solenoid is an electromagnetic device which is used to regulate the vacuum supply to the EGR valve. The solenoid contains a coil which magnetically controls the position of a disc to regulate the vacuum.

What is a P1451 code?
Error Code P1451 is defined as EVAP Control System Canister Vent Solenoid Circuit Malfunction. This code means there’s a leak detected in the EVAP (evaporative emission) system. This error code is a manufacturer-specific trouble code, as it does not apply to all vehicles makes.
What are the symptoms of a bad vacuum solenoid?
Some symptoms of a faulty solenoid include poor idle, poor acceleration, stalling, low engine vacuum and hesitation or rough riding while driving.
How do you test a Ford EGR vacuum solenoid?
What happens when EGR solenoid goes bad?
If the EGR solenoid fails it can disable the EGR system from recirculating exhaust gases. For certain engines this can cause a large increase in cylinder and exhaust gas temperatures. Excessively high cylinder temperatures can cause engine ping and knock, which can lead to serious engine damage if left unattended.
How do I know if my vacuum solenoid is bad?
Symptoms. Some symptoms of a faulty solenoid include poor idle, poor acceleration, stalling, low engine vacuum and hesitation or rough riding while driving.
What is EVAP canister vent solenoid?
The EVAP vent control valve (solenoid), or vent valve, is a part of the EVAP system. It controls the flow of outside air in and out of the charcoal canister. In some cars, it’s called Canister Close Valve (CCV). One side of the vent valve is connected to the charcoal canister.
What is a canister purge solenoid?
The canister purge valve is a vital part of the Evaporative Emission Control System (EVAP). The EVAP system seals the fuel system of your vehicle to prevent harmful fuel vapors from entering the environment. In newer model vehicles the purge valve is electrically operated solenoid controlled by the engine computer.
What happens when EGR solenoid valve is activated?
When the EGR control solenoid is activated, a passage is opened up that allows exhaust gases into the intake manifold. The EGR solenoid is controlled by the engine computer, and activated at very specific times in order to achieve the best performance, efficiency, and emissions from the engine.
