Understanding Engine Diagnostics Services at Sunland Tire
The On-Board Diagnostics (OBD) system was initially designed to monitor vehicle emissions, but it also detects engine problems. There are two types of OBD systems: OBD I and OBD II, with OBD II becoming the standard in vehicles manufactured after 1996. The OBD system connects to the engine control unit (ECU), which helps the engine run efficiently while minimizing emissions. The OBD can identify potential engine malfunctions and alert the driver by sending error codes to the ECU. The ECU is responsible for several engine functions, including air-fuel mixture, emissions control, and engine timing, using sensors to monitor and adjust these processes. When a malfunction is detected, the ECU triggers the “check engine” light, and the OBD system records a diagnostic trouble code (DTC). A technician can access these codes using diagnostic equipment to accurately identify and address the issue.

Why Choose Sunland Tire for Engine Diagnostics Services?
Engine diagnostics are essential for maintaining your engine’s efficiency. The OBD system can detect issues early, preventing reduced engine performance or significant damage. With the OBD system, your vehicle is capable of monitoring and diagnosing its own performance. You should have diagnostics performed whenever the “check engine” light comes on, as this could indicate an issue that needs attention. Early detection allows minor problems to be addressed before they turn into major ones. Engine diagnostics also help ensure your vehicle meets emissions standards; if the engine is malfunctioning, your vehicle may not pass an emissions test. When the “check engine” light appears, contact us for a thorough engine diagnostic service. Our experienced technicians will quickly identify the issue and restore your engine to proper working order.
