18836/P2404/009220 - EVAP Leak Detection Pump Sense Circuit: Implausible Signal

Possible Symptoms

  • Malfunction Indicator Light (MIL) ON

Possible Causes

  • Faulty Leak Detection Pump (V144)
  • Evaporative Emission (EVAP) Canister System leaking pressure
  • Faulty (N80) Evap purge solenoid

Possible Solutions

  • Test Leak Detection Pump (V144) and it's wiring, see repair manual
  • Pressure test Evaporative Emission (EVAP) Canister System for leaks, see repair manual
  • Test (N80) Evap purge solenoid for leaking system pressure into the intake manifold

Special Notes

  • If found on the 2.0L BPY engine, see Technical Bulletin 20-07-13.
