Investigating P0446 on Your 2022 Jeep Compass
A P0446 code on your 2022 Jeep Compass indicates an EVAP vent control circuit malfunction. The MP-generation Compass uses Stellantis' ESIM (Evaporative System Integrity Monitor) module, which integrates vent control and leak detection into a single unit near the charcoal canister.
The 2022 Compass with its 2.4L Tigershark four-cylinder is a compact crossover built for daily commuting. At three to four years old, your basic warranty may still apply, and the emissions warranty is firmly in effect.
Warning Signs
- Check engine light on with P0446
- Fuel nozzle shutting off during fill-ups
- EVAP system monitor not completing
- Possible companion EVAP codes stored
Ranked Causes
- ESIM Module Malfunction (High Likelihood): The integrated vent/leak-detection module is the primary P0446 suspect on the Compass. Internal switch or motor failure is common as these units age. Parts $85–$165, labor $100–$210.
- ESIM Connector Corrosion (High Likelihood): The underbody connector exposure leads to corrosion from road salt and moisture. Repair costs $70–$155.
- Wiring Damage Between ESIM and PCM (Medium Likelihood): The Compass's compact underbody packaging means wiring runs closer to exhaust and moving parts. Repair costs $90–$270.
- Charcoal Canister Issues (Medium Likelihood): Canister saturation from habitual fuel topping-off affects ESIM operation. Parts $140–$290, labor $110–$225.
- PCM Software Update (Low Likelihood): Stellantis calibration updates may address EVAP monitoring sensitivity. Dealer reflash $0–$150.
Diagnostic Steps
- Scan all codes and review freeze frame data
- Inspect ESIM module and connector under the vehicle
- Test ESIM operation using wiTECH bidirectional controls
- Check wiring from ESIM to PCM for continuity and damage
- Perform EVAP smoke test if leak codes are also present
- Check for applicable TSBs and software updates
Cost Breakdown
- ESIM module replacement: $185–$375
- Connector repair: $70–$155
- Wiring repair: $90–$270
- Charcoal canister replacement: $250–$515
- Diagnostic fee: $90–$150
Can I Keep Driving?
Yes. P0446 doesn't affect your Compass's 2.4L Tigershark engine, 9-speed automatic, or available 4WD system. Fuel economy and driving dynamics remain normal.
Warranty Check
Your 2022 Compass may still be within Jeep's 3-year/36,000-mile basic warranty depending on purchase date and mileage. The federal emissions warranty covers EVAP for 8 years/80,000 miles through 2030. Check with your dealer first.
