Fiat Seiscento SX P0352 Error: Cold Start Misfire on Cylinder 2

Model: Fiat Seiscento SX Fault Code: P0352 Posted: 2011-12-03 19:49

I apologize for my English being limited. My Fiat Seiscento SX is showing fault code P0352, which indicates a malfunction in the second spark plug coil. When the engine is cold and I start it, the vehicle seems to run on only two cylinders — this behavior disappears after 2 to 3 seconds. This issue occurs exclusively when the engine is cold; once warmed up, the engine runs normally. I have already tested by swapping the spark coils, but the P0352 code remains associated with cylinder 2. I replaced the coil pack for cylinder 2 with a new one, yet the problem persists. What other diagnostic steps or components should I check to resolve this issue?

Check the wiring and electrical connections to the spark plug coil for cylinder 2. Ensure there are no loose, corroded, or damaged wires or connectors.

The issue was resolved after replacing the ECU; this suggests a possible fault in the engine control module triggering the misfire code despite proper coil replacement.
