P0601 Diagnostic Code in 2001 Dodge Neon SE: Causes and Solutions

Model: dodge neon Fault Code: P0601 Posted: 2010-09-21 19:18

I have a 2001 Dodge Neon SE with a 2.0L engine, currently at 87,340 miles. The check engine light is on, and the trouble code displayed is P0601 — indicating that the Powertrain Control Module (PCM) is failing to complete diagnostics across all systems. The vehicle experiences intermittent engine stumbles during both idle and driving conditions. I'm wondering if replacing the PCM is the only viable solution or if there are other potential fixes. Any insights from owners of similar models would be greatly appreciated. DavidA
