Market analysis

How much does a used Chrysler 300 engine computer cost?

Asking prices for a used Chrysler 300 engine computer are unusually spread out: the top listing asks more than ten times what the cheapest does, so which unit you pick matters more than the median. Condition matters: grade-A units (lowest mileage, best condition) carry roughly a 65% premium over grade-C stock, with grade-A medians at $165.

Fitment variant moves the price more than most buyers expect. The most affordable variant we track, Electronic Control Module, 3.6L, lists at a $162 median, while Electronic Control Module, 6.4L commands $217, a 34% gap inside the same part category. Confirm which variant your VIN requires before comparing quotes.

Model year matters too: 2015 units carry the lowest median at $105, while 2023 tops the table at $211. Year-level pages linked in the table above break each one down by grade and variant.

Against comparable vehicles, the Chrysler 300 sits 48% above the Honda Accord ($112), 50% above the Honda Civic ($111), and 32% above the Hyundai Elantra ($126) for the same part. The “similar vehicles” cards below open each comparison guide.

Buying a used engine computer: what to check

  1. Match hardware and service numbers: Ensure hardware revision codes and circuit board part numbers match exactly, as pinouts change mid-model year.
  2. Inspect multi-pin connector headers: Check header pins for bending, green copper oxidation, or burnt circuit board traces inside the wiring sockets.
  3. Verify immobilizer programming requirements: Plan for anti-theft security relearn procedures or ECU re-flashing before the replacement computer will start the engine.
  4. Confirm donor transmission and emissions spec: Ensure the donor vehicle used the same transmission type and regional emissions package to prevent fault codes.
  5. Check aluminum casing seals: Inspect housing screws and perimeter rubber gaskets for white oxidation or breaks that indicate past water intrusion.
