Solving P0446 on Your 2024 Jeep Compass
A P0446 code on your 2024 Jeep Compass indicates an EVAP vent control circuit malfunction. The redesigned 2024 Compass features a new 2.0L turbocharged four-cylinder engine replacing the previous 2.4L Tigershark, along with a thoroughly updated platform and interior.
Under full factory warranty, this is a no-cost dealer repair. The redesigned EVAP system may have first-year calibration sensitivities that a software update can address.
Symptoms Detected
- Check engine light on with P0446 stored
- Fuel fill difficulties — nozzle clicking off
- EVAP readiness monitor incomplete
- Possible companion codes present
Likely Causes
- ESIM Module Defect (High Likelihood): The redesigned Compass carries an updated ESIM module. First-year production parts may have manufacturing variations. Warranty-covered.
- PCM Software Calibration (High Likelihood): First model year of the redesign means EVAP monitoring parameters may need fine-tuning. A reflash is the simplest fix. Warranty-covered.
- Factory Connector or Wiring Issue (Medium Likelihood): New assembly process means potential variation in connector seating or wire routing. Warranty-covered.
- EVAP System Assembly Variance (Medium Likelihood): New platform with new EVAP line routing — potential for loose or improperly seated connections from the factory. Warranty-covered.
- Gas Cap Seal (Low Likelihood): Factory cap may not seal perfectly. Quick warranty replacement. Warranty-covered.
