Turbo

📖 YOUCANIC Automotive Glossary

A turbocharger uses a turbine driven by exhaust flow to spin a compressor that pressurizes intake air, producing 30-50% more power than an equivalent naturally aspirated engine. Modern turbo systems include a wastegate (limiting boost), intercooler (cooling compressed air), and electronic boost control managed by the ECU.

Common problems include boost leaks from cracked hoses (power loss, lean codes), wastegate failure (over/underboosting), and turbo bearing wear from oil coking. DTCs: P0299 (Underboost), P0234 (Overboost). The YOUCANIC UCAN-II displays boost pressure, wastegate duty cycle, and turbo live data. After turbo replacement, a turbo adaptation reset ensures proper ECU control.
