The P1351 error code indicates a malfunction in the ignition control system. This issue is very common in Peugeot and Citroën vehicles, especially in the popular p1351 Peugeot 1.6 HDi engine models. It can lead to reduced engine performance, poor acceleration, and increased emissions. In this guide, we’ll explore the symptoms, causes, and solutions, while emphasizing the importance of using professional diagnostic tools like the iCarsoft CR MAX and CR Eagle, which are advanced vehicle diagnostic tools and full OBD2 diagnostic tools.
1. What Does P1351 Code Mean?
The P1351 code is triggered when the Engine Control Module (ECM) detects a malfunction in the ignition control system. This system is designed to regulate the ignition timing to control the engine's performance. A malfunction can result in reduced engine performance and increased emissions. This is especially frequent in p1351 Peugeot 1.6 HDi engines due to their ignition relay and glow plug circuits.
2. Symptoms of P1351 Code
- Check Engine Light illumination
- Reduced engine performance
- Poor acceleration
- Rough idling
- Increased emissions
3. Common Causes
- Faulty ignition coil
- Damaged wiring or connectors in the ignition control system
- Blown fuse related to the ignition control system
- Failed Engine Control Module (ECM)
- Corroded or loose electrical connections
- Glow plug relay issues (common in Peugeot 1.6 HDi P1351 engines)
4. Diagnostic Methods
Accurate diagnosis requires professional-grade diagnostic equipment like the iCarsoft CR MAX and CR Eagle, which are advanced bluetooth vehicle scan tools and full OBD2 diagnostic tools. These tools provide:
- OBD-II scanning to retrieve the P1351 code
- Real-time data monitoring of ignition and glow plug system
- Circuit testing capabilities for wiring and connectors
- Repair verification to ensure the issue is resolved
5. Steps to Fix
- Perform a complete system scan using a professional tool like the iCarsoft CR MAX or CR Eagle.
- Inspect the ignition coil and its wiring for damage.
- Check the glow plug relay in Peugeot 1.6 HDi P1351 models.
- Test the circuit for continuity and proper voltage.
- Replace the ignition coil or relay if faulty.
- Repair or replace damaged wiring and connectors.
- Clear the code and test the system to ensure the issue is resolved.
6. Importance of Ignition Control System
The ignition control system is critical for:
- Regulating engine ignition timing
- Maintaining engine performance
- Ensuring smooth acceleration
- Reducing emissions
7. Preventive Measures
- Regularly inspect the ignition control system components.
- Check and replace fuses as needed.
- Ensure all electrical connections are secure and corrosion-free.
- Monitor engine performance and address irregularities promptly.
- Follow the manufacturer's recommended maintenance schedule.
