Diesel Turbo Charger and Waste Gate Troubleshooting

Diesel turbochargers are devices that compress air and force it into the engine’s combustion chamber, allowing for more fuel to be burned and increasing the engine’s power output. A wastegate is a valve that regulates the amount of exhaust gas that enters the turbocharger, controlling the speed at which the turbocharger spins. Troubleshooting a diesel turbocharger and wastegate involves identifying and resolving issues that may cause the turbocharger to malfunction. Common problems include a lack of boost from the turbocharger, poor fuel economy, and a decrease in engine power. Detroit Diesel has a training video that explains the operation, troubleshooting, and adjustment of diesel engine turbochargers, including wastegate turbocharger troubleshooting. Another source provides an overview of how wastegates work, wastegate calibration, common problems, and more. If you suspect that your wastegate hose is broken or blocked, you may experience a dramatic decrease in fuel economy, among other symptoms. If you’re experiencing any issues with your diesel turbocharger or wastegate, it’s best to consult a professional mechanic for assistance.
