P2407 on Volkswagen
Evaporative Emission System Leak Detection Pump Sense Circuit Intermittent/Erratic
P2407 on Volkswagen vehicles indicates evaporative emission system leak detection pump sense circuit intermittent/erratic. Au7o has documented this code across 1 Volkswagen model — most commonly on Golf R. This code indicates the Engine Control Module (ECM) has detected an intermittent or erratic signal on the evaporative emission (EVAP) system leak detection pump sense circuit. The leak detection pump is used to pressurize the EVAP system to check for fuel vapor leaks, and an unstable or inconsistent reading from its sense circuit triggers this fault. It is an emissions/monitoring issue rather than a drivability problem. Typical repair costs on Volkswagen range from $30 to $500, depending on the specific model and root cause.
Common Causes of P2407
- •Corroded, loose, or damaged electrical connector at the EVAP leak detection pump
- •Frayed, chafed, or intermittently shorting wiring in the leak detection pump sense circuit
- •Faulty EVAP leak detection pump (internal sensor or motor fault)
- •Poor ground or intermittent open in the circuit harness
- •Failed or failing ECM/PCM (less common)
P2407 on Volkswagen by Model
Volkswagen Golf R(1 issue)
- EVAP N80 Purge Valve Failure and Large/Small Leak Codes2015-2022
The EVAP system on MQB-platform Golf R (MK7/MK7.5, with some MK8 cases) frequently throws evaporative-emissions leak faults. The most common culprit is the N80 purge valve failing to seal, but the leak-detection pump, carbon (charcoal) canister breakdown, and saturated canister from overfilling the tank also trigger codes. Symptoms are a check engine light with small- or large-leak codes, occasional rough idle or hesitation just after start, and sometimes a fuel smell. Often surfaces around emissions/inspection (relevant for EU periodic technical inspection).

What does P2407 mean on Volkswagen?▼
P2407 stands for "Evaporative Emission System Leak Detection Pump Sense Circuit Intermittent/Erratic." This code indicates the Engine Control Module (ECM) has detected an intermittent or erratic signal on the evaporative emission (EVAP) system leak detection pump sense circuit. The leak detection pump is used to pressurize the EVAP system to check for fuel vapor leaks, and an unstable or inconsistent reading from its sense circuit triggers this fault. It is an emissions/monitoring issue rather than a drivability problem. On Volkswagen specifically, this code is documented across 1 model.
What causes P2407 on Volkswagen vehicles?▼
Common causes on Volkswagen: Corroded, loose, or damaged electrical connector at the EVAP leak detection pump, Frayed, chafed, or intermittently shorting wiring in the leak detection pump sense circuit, Faulty EVAP leak detection pump (internal sensor or motor fault), Poor ground or intermittent open in the circuit harness, Failed or failing ECM/PCM (less common). Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P2407 on a Volkswagen?▼
