At Grade A (excellent) condition, the Honda Civic is 53% cheaper ($113 vs $241) — the gap widens compared to the overall median difference.
The Honda Civic has 6 known trim variants compared to 3 for the Lexus NX300, which means buyers need to be more careful about matching the exact engine or drivetrain configuration on the Honda Civic.
Buyer's checklist
What to check before buying a used engine computer
- Match the hardware part number and catch code exactly, as internal board architecture varies even within the same vehicle year and engine family.
- Confirm security anti-theft (PATS, PASS-Key, or Immobilizer) pairing requirements, as used ECMs almost always require VIN programming before starting the vehicle.
- Inspect connector headers for bent pins, thermal discoloration, or green corrosion indicating water leakage through the wiring harness plug.
- Verify emission tier compatibility (Federal/EPA vs. California CARB standards) and transmission control integration (PCM vs standalone ECM/TCM).
