P0351 on Peugeot
Ignition Coil A Primary/Secondary Circuit Malfunction
P0351 on Peugeot vehicles indicates ignition coil a primary/secondary circuit malfunction. Au7o has documented this code across 1 Peugeot model — most commonly on 206. P0351 indicates the engine computer found a fault in the primary or secondary circuit of ignition coil 'A' (typically the coil for cylinder 1 or the first coil in the firing system). The PCM monitors the coil's control circuit, and when the electrical feedback doesn't match what it expects during firing, it sets this code. Because the coil creates the high-voltage spark, this often causes a misfire, rough idle, hesitation, or loss of power. It is a circuit/component fault for one specific coil rather than a general engine problem. Typical repair costs on Peugeot range from $80 to $250, depending on the specific model and root cause.
Common Causes of P0351
- •Failed or weak ignition coil
- •Damaged or corroded coil connector or pigtail
- •Broken or shorted wiring in the coil control circuit
- •Loss of power feed or ground to the coil
- •Worn or fouled spark plug overloading the coil
- •Failed coil driver inside the PCM/ECM
P0351 on Peugeot by Model
Peugeot 206(1 issue)
- Ignition Coil Pack Failure (Petrol TU Engines)1998-2012
The wasted-spark coil pack on the 206's small petrol engines (1.1 KFV, 1.4 KFW and related TU units) is a frequent failure item: one of the two internal coils breaks down, dropping spark on a paired set of cylinders (1/4 or 2/3). Owners report intermittent misfire, rough running, the engine cutting out and refusing to restart until it cools, and the management light flickering. Forum consensus also warns that cheap aftermarket replacement packs often fail repeatedly or seat poorly, causing the fault to return.

What does P0351 mean on Peugeot?▼
P0351 stands for "Ignition Coil A Primary/Secondary Circuit Malfunction." P0351 indicates the engine computer found a fault in the primary or secondary circuit of ignition coil 'A' (typically the coil for cylinder 1 or the first coil in the firing system).
