What does the ecu control on your 1988 ford ranger?

The Engine Control Unit (ECU) in a 1988 Ford Ranger primarily manages the engine's fuel injection and ignition timing to optimize performance and emissions. It receives inputs from various sensors, such as the throttle position sensor and oxygen sensor, to adjust fuel delivery and ignition timing accordingly. Additionally, the ECU monitors engine conditions and can trigger diagnostic trouble codes if it detects issues, aiding in vehicle maintenance and troubleshooting. Overall, it plays a crucial role in ensuring the engine runs efficiently and reliably.
