Code P10CC Description

The P10CC diagnostic trouble code (DTC) refers to the Exhaust Aftertreatment Fuel Injector Control Circuit being shorted. This code indicates that there is a malfunction in the control circuit of the fuel injector in the exhaust aftertreatment system. The exhaust aftertreatment system is responsible for reducing harmful emissions from the vehicle's exhaust gases, and the fuel injector plays a crucial role in this process by injecting fuel into the exhaust stream to facilitate the regeneration of the diesel particulate filter (DPF) or selective catalytic reduction (SCR) system.

  4. Connector Issues: Loose or damaged connectors can also trigger this code.

Symptoms of P10CC

  1. Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
  2. Reduced Engine Performance: The vehicle may experience a decrease in engine power and overall performance.
  3. Increased Emissions: The vehicle may emit higher levels of pollutants due to the malfunction in the exhaust aftertreatment system.
  4. Poor Fuel Economy: The vehicle may exhibit decreased fuel efficiency as a result of the issue with the fuel injector control circuit.

How to Fix P10CC

  1. Diagnose the Issue: Use a diagnostic scanner to retrieve the trouble code and pinpoint the exact cause of the problem.
  2. Inspect Wiring Harness: Check the wiring harness for any signs of damage or wear and replace any faulty wiring.
  3. Test Fuel Injector: Test the fuel injector to ensure it is functioning properly and replace it if necessary.
  4. Check Connectors: Inspect the connectors for the fuel injector control circuit and repair or replace any damaged connectors.
  5. Clear Codes: After completing the repairs, clear the DTC and test drive the vehicle to ensure the issue has been resolved.

Cost to Fix P10CC

The typical repair costs for addressing a P10CC code can range from $200 to $500, including parts and labor. However, it is important to note that the specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. Auto repair shops commonly charge between $80 and $150 per hour for labor, but rates may be higher in metropolitan areas or at dealerships, while independent shops may offer lower rates.
