- Glow plugs : They heat the combustion chambers to facilitate starting.
- Preheating relay : It controls the power supply to the spark plugs.
- Electronic Control Unit (ECU) : It oversees the overall operation of the system.
A malfunction in any of these components can generate the P1351 code. For example, a faulty spark plug or a faulty glow plug relay can prevent the engine from starting properly in cold weather.
Possible causes
There are several factors that can cause the P1351 code to appear:
- Electrical harness : A damaged harness can cause interruptions in the circuit.
- Battery : Insufficient power supply may affect preheating.
- Engine Control Module (ECM) : An ECM malfunction may also be the cause.
- Fuel system : Problems in the fuel supply can disrupt preheating.
- Cooling system : Anomalies in this system can also affect starting.
Modern Peugeot vehicles, like other brands such as Ford and Citroen, can encounter this error code. A thorough understanding and methodical inspection of the glow plug circuit components is therefore essential to effectively resolve this issue.
Causes and symptoms of code P1351
Identifying the causes and symptoms of the P1351 code is fundamental for effective intervention on modern Peugeot vehicles. The preheating circuit, which includes the glow plugsthe preheating relay and the electronic control unit (ECU)is often at the heart of the problem.
Potential causes
There are several components that can cause this error code:
- Electrical harness : A damaged harness can interrupt the circuit.
- Battery : Insufficient power supply may disrupt preheating.
- Engine Control Module (ECM) : An ECM malfunction can generate code P1351.
- Fuel system : Fuel supply anomalies may affect preheating.
- Cooling system : Problems in this system can also play a role.
Observable symptoms
Symptoms associated with the P1351 code typically include difficulty starting, especially in cold weather. Warning lights may illuminate on the dashboard, indicating a fault in the glow plug system. The engine may also run rough or lose performance.
Consider these elements for an accurate diagnosis and quick resolution of the problem. Peugeot vehicles, as well as those of brands such as Ford and Citroën, can be affected by this error code, requiring special attention to the components of the preheating circuit.
