ECM Replacement (Engine Control Module) Cost & Pricing
Replace the ECM — the main computer that controls fuel injection, ignition timing, emissions, and engine performance. A failed ECM causes drivability issues, stalling, no-start, or a flood of unrelated fault codes.
Typical ECM Replacement (Engine Control Module) cost
$800–$2,120, with an average estimate of $1,220 before vehicle-specific adjustments.
What to expect
Difficulty: moderate. Typical labor time: 1–3 hours.
Mechanic's tip
ECMs rarely fail on their own — before replacing, rule out corroded connectors, bad grounds, and power supply issues, all of which can mimic ECM failure. A new ECM must be programmed to the vehicle's VIN; this requires a dealer or specialist with programming equipment and adds $100–300 to the cost. Remanufactured ECMs are a reliable, lower-cost option but still require programming.
