P141C Ford Code - Exhaust Gas Recirculation Sensor 'C' Circuit Intermittent/Erratic
Quick Answer
The P141C Ford diagnostic trouble code indicates a problem with the Exhaust Gas Recirculation (EGR) sensor 'C' circuit, specifically that the signal being received is intermittent or erratic. Common causes include Faulty EGR Sensor 'C': The sensor itself may be malfunctioning, sending erratic signals to the ECM, Wiring Issues: Damaged or corroded wiring connections between the EGR sensor 'C' and the ECM can cause intermittent signal problems, ECM Malfunction: A fault in the engine control module can also lead to erroneous readings from the EGR sensor 'C'. 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 P141C Ford Description
The P141C Ford diagnostic trouble code indicates a problem with the Exhaust Gas Recirculation (EGR) sensor 'C' circuit, specifically that the signal being received is intermittent or erratic. The EGR system plays a crucial role in reducing harmful emissions by recirculating a portion of the exhaust gases back into the engine's intake manifold. The EGR sensor 'C' is responsible for monitoring the EGR system's operation and providing feedback to the engine control module (ECM) to ensure proper functionality.
Common Causes of P141C Ford
- Faulty EGR Sensor 'C': The sensor itself may be malfunctioning, sending erratic signals to the ECM.
- Wiring Issues: Damaged or corroded wiring connections between the EGR sensor 'C' and the ECM can cause intermittent signal problems.
- ECM Malfunction: A fault in the engine control module can also lead to erroneous readings from the EGR sensor 'C'.
- Vacuum Leaks: Any leaks in the vacuum lines connected to the EGR system can disrupt the sensor's operation.
- Carbon Buildup: Accumulated carbon deposits in the EGR system can obstruct the sensor's function and cause erratic readings.
Symptoms of P141C Ford
- Check Engine Light: The most common symptom associated with this code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Rough Idle: A faulty EGR sensor 'C' can cause the engine to idle roughly or inconsistently, leading to a shaky or vibrating sensation.
- Decreased Fuel Efficiency: The erratic EGR sensor signal can result in improper fuel-air mixture ratios, causing decreased fuel efficiency and potentially higher fuel consumption.
- Engine Performance Issues: The vehicle may experience a lack of power, hesitation, or sluggish acceleration due to the EGR system not functioning correctly.
How to Fix P141C Ford
- Diagnose the Issue: Use a scan tool to retrieve the trouble code and perform a thorough inspection of the EGR sensor 'C', wiring, and connections to identify the root cause of the problem.
- Replace EGR Sensor 'C': If the sensor is found to be faulty, replace it with a new one following the manufacturer's guidelines.
- Repair Wiring: Repair or replace any damaged wiring connections to ensure a stable signal between the sensor and the ECM.
- Clean EGR System: Remove any carbon buildup in the EGR system, including the EGR valve and passages, to prevent future issues.
- Clear Codes: After completing the repairs, clear the trouble codes from the ECM's memory and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P141C Ford
The cost of repairing a P141C Ford code can vary depending on the specific cause of the issue and the labor rates in your area. On average, you can expect to pay between $200 and $500 for parts and labor to address this problem. Keep in mind that diagnostic time and labor rates at auto repair shops can fluctuate, so it's recommended to obtain quotes from multiple sources to get an accurate estimate for your vehicle. Additionally, factors such as the vehicle make and model, engine type, and location can influence the overall repair costs.
