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)
- Voltage supply problems to 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
- Check voltage supply to Leak Detection Pump (V144) including J757 - Engine Component Power Supply Relay when applicable
- 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.
