What does a purge solenoid do?

What does a purge solenoid do?

The canister purge solenoid is the component in the EVAP system that is responsible for “purging” the EVAP system, by acting as the switch that allows the vapor into the engine. When the purge solenoid fails, it will cause problems for the EVAP system, which will affect the vehicle’s emissions output levels.

Where is purge solenoid located?

The Canister purge control valve is most often located in the engine bay on a hose going from the intake to the canister. It can also be located near the fuel tank.

What are the symptoms of a bad purge valve solenoid?

Bad Purge Valve Solenoid Symptoms

  • Illuminated Check Engine Light. If the module detects a problem with the purge valve, it turns on the check engine light and stores a corresponding diagnostic trouble code (DTC) in its memory.
  • Engine Performance Problems.
  • Hard Starting After Refueling.
  • Collapsed Fuel Tank.

What is the OBD 2 fault code p1443?

OBD II fault code P1443 is a manufacturer specific code that carmakers Ford, Lincoln, Mazda, and Mercury define as “Evaporative Emission Control System Control Valve”, and on these applications, the code is set when the PCM (Powertrain Control Module) detects a malfunction of the EVAP (Evaporative Emissions Control System) purge control valve.

Can a p1443 code be the cause of an EVAP code?

NOTE: Be aware that if other EVAP related codes are present along with P1443, these codes are often the result of P1443, rather than the cause. Therefore, if code P1443 is accompanied by other codes check if the other codes follow P1443; if they do, they are the result of this code, and they will likely clear automatically when P1443 is resolved.

What kind of problem is a p1443 purge valve?

Defective purge valve and/or control solenoid. Damaged, burnt, shorted, corroded, and disconnected wiring and/or connectors. Note however that although wiring issues are usually be indicated by codes other the P1443, P1443 may be present as well. Damaged, split, hardened, dislodged, or degraded vacuum lines.
