P1467 · VolkswagenEVAP Canister Purge Solenoid Valve Short To B+

P1467 on a Volkswagen means the engine control module (ECM) has detected a short to battery positive voltage on the electrical circuit that controls the EVAP canister purge solenoid valve. The ECM commands the purge valve to open and close, and it monitors the control wire for an unexpected high voltage when the valve should be off, indicating a wiring fault rather than a mechanical purge valve failure.

Symptoms you may notice

  • Illuminated check engine light, often with no other noticeable symptoms
  • Rough idle or stumbling after refueling due to incorrect purge flow
  • A strong fuel odor around the engine bay or from the EVAP canister area
  • Slightly increased fuel consumption because the purge strategy is disabled
  • In some cases, the engine may hesitate or stall when coming to a stop
  • No drivability issues at all if the short is intermittent and only sets the code

Common causes, most likely first

  1. Chafed or damaged purge solenoid control wire shorting to a nearby battery positive wire in the engine harness
  2. Failed purge solenoid valve with an internal short to its power feed
  3. Corroded or water-intruded connector at the purge solenoid allowing voltage to bleed to the control circuit
  4. Faulty ECM driver for the purge solenoid, though this is rare compared to wiring faults
  5. Aftermarket alarm or accessory wiring improperly tapped into the purge circuit
  6. Rodent damage to the harness insulation exposing the control wire to a power source

How to diagnose and fix it

  1. Clear the code and verify it returns; if it is intermittent, inspect the harness for obvious damage first
  2. Disconnect the purge solenoid connector and check for battery voltage on the control wire with the key on and the engine off
  3. Inspect the purge solenoid control wire along its full length for chafing, pinches, or contact with other powered circuits
  4. Measure resistance across the purge solenoid terminals and compare to the manufacturer specification to rule out an internal short
  5. Check the purge solenoid connector pins for corrosion, water intrusion, or pushed-out terminals
  6. If the wire is shorted to power, repair the harness with proper solder and heat-shrink, then re-test
  7. If the ECM driver is suspected, perform a continuity and voltage-drop test on the control circuit before condemning the ECM

Before you replace the purge solenoid

  • A short to B+ on the purge control wire often comes from a rubbed-through section of harness near the intake manifold or battery tray, not from the solenoid itself.
  • The ECM may set P1467 even when the purge valve mechanically works fine, because the code is purely electrical and does not test flow.
  • Aftermarket remote starters or alarm systems tapped into the wrong wire are a frequent hidden cause on older Volkswagen models.
  • A poor ground at the purge solenoid can mimic a short to B+ on some scan tools, so always verify ground integrity before chasing the power side.
  • This code can appear alongside EVAP leak codes if the short causes the purge valve to stick open, so do not assume the leak is the root cause.

Can I keep driving with P1467?

You can usually drive with P1467 set, but avoid refueling with the engine running and do not ignore a strong fuel smell, as a stuck-open purge valve can flood the intake with fuel vapor. Have the circuit inspected soon to prevent potential EVAP system damage or drivability issues.
