The P0302 code on your 2020 Ford Edge indicates the PCM detected repeated misfires in cylinder 2. The Edge offers two EcoBoost engine options, each with specific diagnostic considerations.
2020 Edge Engine Options
The 2020 Edge offered the 2.0L EcoBoost 4-cylinder (standard) and 2.7L EcoBoost V6 (ST model). Both are turbocharged with direct injection. Cylinder 2 location differs between the 4-cylinder and V6 configurations.
Age-Related Considerations
At 4+ years old, the 2020 Edge may experience misfire from wear items. Common causes include worn spark plugs, failing ignition coils, carbon buildup on intake valves (especially with city driving), and fuel injector issues.
EcoBoost Specifics
Both Edge engines use direct injection, which can cause carbon buildup on intake valves over time since fuel doesn't wash the valves. If ignition components check out, consider carbon cleaning.
Diagnostic Approach
Start with the coil swap test—it's the most efficient way to identify ignition failures. On the 4-cylinder, cylinder 2 is the second from front. On the V6, consult the service manual for cylinder numbering.
