Description
This main computer monitors real-time data from engine sensors and adjusts ignition timing, fuel delivery, and emissions systems. It keeps your engine running smoothly and efficiently under all driving conditions. Therefore, you must replace failing or shorted control units to fix rough idling, poor fuel economy, and engine starting failures.
Built with original microprocessors and sealed circuit boards, this original ECU handles high engine bay temperatures and vibrations without failing. Also, it plugs directly into your factory wiring harness so installation and programming are exact and secure.
Cheap aftermarket or rebuilt computer units use low-quality chips and poor soldering. Consequently, they cause erratic sensor readings, persistent check engine lights, and unexpected engine stall hazards.
