If your 2024 Jeep Compass is displaying a P0305 code indicating a cylinder 5 misfire, this code requires diagnostic investigation. The 2024 Compass uses a 2.0L turbocharged four-cylinder engine as its sole powertrain. With only four cylinders numbered 1-4, P0305 is technically anomalous.
2024 Compass Powertrain
The refreshed 2024 Compass uses the 2.0L turbocharged I-4 producing 200 horsepower, replacing the previous 2.4L naturally aspirated engine. This is the only engine available. No V6 has ever been offered.
Why P0305 Cannot Be Valid
The 2024 Compass's 2.0L turbo has exactly four cylinders. A P0305 code references a non-existent cylinder 5, indicating a diagnostic error.
Possible Causes
ECM software issues can store invalid codes. Scan tool communication errors may misread data. Low battery voltage affects ECM reliability. As a refreshed model, check for TSBs addressing known software issues.
Diagnostic Recommendations
Use a Stellantis-compatible scan tool to verify codes. Check for TSBs. Test battery condition. If actual misfire symptoms exist, focus on cylinders 1-4. Clear the erroneous code.
