2006 Chrysler PT Cruiser P0830 Fault Code: Clutch Interlock Switch Circuit Issue and Rev Limitation
I own a 2006 facelift Chrysler PT Cruiser with a 2.2L diesel CRD manual transmission. The vehicle will not rev past 2500 RPM, despite no visible engine management light or dashboard warning. When I connected my brother-in-law's OBD2 scanner, it displayed fault code P0830 — 'Clutch Interlock Switch Circuit' (T141). There is no check engine light on, and the clutch pedal switch appears functional after testing both up and down positions. The previous garage repaired the clutch but did not address this issue. I've since inspected the wiring harness and found that two cables had previously grounded due to improper insulation during repair — these have been re-routed and insulated. However, the problem persists. I'm wondering if P0830 directly causes the rev limitation or if it's a symptom of a deeper electrical issue. The internet suggests timing belt problems in petrol PT Cruisers, but diesel models use chains. I'm concerned that local garages may not have access to advanced diagnostic tools — could Chrysler dealership equipment detect this code more reliably than consumer-grade OBD2 scanners? Any insights or troubleshooting steps for P0830 on a 2006 PT Cruiser CRD would be greatly appreciated.
What year is your PT Cruiser?\nPossible Causes:\n- INTERMITTENT DTC: (T141) Clutch Interlock Switch Signal Circuit Shorted to Voltage\n- (T141) Clutch Interlock Switch Signal Circuit Shorted to Ground\n- (T141) Clutch Interlock Switch Signal Circuit Open or High Resistance\n- (Z906) Ground Circuit Open or High Resistance\n- Clutch Interlock Switch malfunction\n- Engine Control Module (ECM) failure\nFYI: Always use a dedicated OBD2 scanner — not all devices can read every code. The 'key on-off' trick does not guarantee full code retrieval.
