P200C Code - Diesel Particulate Filter High Temperature
Quick Answer
The P200C diagnostic trouble code (DTC) indicates a problem with the Diesel Particulate Filter (DPF) in a diesel engine. Common causes include Malfunctioning EGR system: A faulty EGR system can cause excess soot to be produced, leading to high temperatures in the DPF, Faulty DOC: A malfunctioning diesel oxidation catalyst can result in incomplete combustion, increasing soot production and DPF temperatures, Clogged DPF: A blocked DPF can restrict exhaust flow, causing temperatures to rise in the filter. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P200C Description
The P200C diagnostic trouble code (DTC) indicates a problem with the Diesel Particulate Filter (DPF) in a diesel engine. The DPF is designed to capture and store soot particles emitted during the combustion process, preventing them from being released into the atmosphere. When the DPF reaches high temperatures, it can result in a variety of issues that can affect the vehicle's performance and emissions.
Common Causes of P200C
- Malfunctioning EGR system: A faulty EGR system can cause excess soot to be produced, leading to high temperatures in the DPF.
- Faulty DOC: A malfunctioning diesel oxidation catalyst can result in incomplete combustion, increasing soot production and DPF temperatures.
- Clogged DPF: A blocked DPF can restrict exhaust flow, causing temperatures to rise in the filter.
- Engine running too rich: An excessively rich air-fuel mixture can lead to increased soot production and high temperatures in the DPF.
Symptoms of P200C
- Reduced fuel efficiency: High DPF temperatures can lead to increased fuel consumption as the engine works harder to maintain proper combustion.
- Loss of power: The engine may experience a decrease in power output due to restricted exhaust flow caused by the high temperature in the DPF.
- Increased emissions: The vehicle may emit higher levels of harmful pollutants due to the DPF not functioning properly.
- Engine misfires: High DPF temperatures can cause the engine to misfire or run rough due to the impact on combustion.
How to Fix P200C
- Diagnose the issue: Use a diagnostic scanner to retrieve the DTC and pinpoint the exact cause of the high DPF temperatures.
- Check the EGR system: Inspect the EGR system for any faults or leaks that could be contributing to the problem.
- Clean or replace the DPF: If the DPF is clogged, it may need to be cleaned or replaced to restore proper function.
- Repair or replace the DOC: If the diesel oxidation catalyst is faulty, it may need to be repaired or replaced to prevent high DPF temperatures.
- Address engine issues: If the engine is running too rich, diagnose and repair any underlying issues that could be causing the problem.
Cost to Fix P200C
The cost of repairing a Diesel Particulate Filter High Temperature issue can vary depending on the extent of the problem and the specific repairs needed. In general, the cost of replacing a clogged DPF can range from $1,000 to $3,000, including parts and labor. Cleaning the DPF may be a more affordable option, costing between $200 and $500. Repairing or replacing other components such as the EGR system or diesel oxidation catalyst can add to the overall cost. It's important to factor in diagnostic time and labor rates, which can vary depending on the location and the auto repair shop. It's recommended to get a personalized estimate from a qualified mechanic to determine the exact cost for your specific vehicle.
