Engine

D13 Engine

  • Erratic Idle Speed: The engine idle speed may fluctuate or become erratic, causing the truck to shudder or stall. This issue can be caused by a faulty idle speed control valve or a problem with the engine management system. Solution: Replace the idle speed control valve or repair the engine management system. Estimated Cost to Fix: $500 - $1,000+
  • Turbocharger Failure: The turbocharger may fail, resulting in a loss of power and fuel efficiency. The failure can be due to a faulty turbocharger housing or a problem with the turbocharger’s bearings. Solution: Replace the turbocharger. Estimated Cost to Fix: $2,000 - $4,000+
  • Injector Failure: The fuel injectors may fail, causing the engine to run rough or stall. This issue can be caused by a faulty injector or a problem with the fuel supply system. Solution: Replace the faulty injector or repair the fuel supply system. Estimated Cost to Fix: $500 - $1,000+
  • Exhaust Gas Recirculation (EGR) System Failure: The EGR system may fail, causing the engine to lose power and emit excessive exhaust emissions.
