2006 Chrysler PT Cruiser P0830 Fault Code: Clutch Interlock Switch Circuit Issue and Rev Limitation

Model: 2006 Chrysler PT Cruiser Fault Code: P0830 Posted: 2018-07-03 00:22

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.

Thanks for the reply — it's a 2006 facelift model.

Still having trouble diagnosing this. I've tested both clutch pedal position switches and confirmed they're working correctly. During a prior repair, two wires were found to have grounded due to poor insulation and tape wrapping — these have been re-routed and properly insulated. However, the issue remains. It's a 2.2L CRD diesel with a chain-driven timing system (not belt). I've seen online discussions suggesting timing belt issues in petrol models, but that doesn't apply here. Could Chrysler dealership diagnostic systems detect P0830 more accurately than local garages using basic scanners?

P0830 Set Condition: The Engine Control Module (ECM) detects an implausible voltage signal in the T141 Clutch Interlock Switch Signal circuit. This strongly indicates a wiring or sensor fault — not a mechanical issue, but likely a short, open circuit, or poor grounding.

You asked: 'There is no light on the dash showing any fault but when I plugged in my brother-in-law's OBD2 gizmo, P0830 appeared.'\n1. The key-on-off trick does NOT reliably trigger all stored codes.\n2. Not all fault codes activate the check engine light (CEL).\n3. Some consumer-grade scanners may not support advanced diagnostic protocols — especially in later models or specific regions like Europe.\nPlease let me know if this helps.\ngod save the queen.
