FAQs

An Engine Control Unit (ECU) is the electronic brain of your vehicle’s engine. It monitors and controls critical engine functions including fuel injection, ignition timing, air-fuel ratio, idle speed, and emissions. It receives data from various sensors throughout your vehicle and makes real-time adjustments to ensure optimal performance, fuel efficiency, and reduced emissions. Without a functioning ECU, your engine simply won’t run properly – or at all.

Common signs of a failing ECU include:

• Check Engine Light illuminated with no clear cause

• Engine misfiring, stalling, or rough idling

• Poor fuel economy

• Difficulty starting or engine not starting at all

• Sudden loss of power while driving

• Transmission shifting problems

• Erratic dashboard gauge readings

If you’re experiencing any of these issues, we recommend having your vehicle diagnosed by a professional. Our team can also help identify if an ECU replacement is needed.
