Factory diagnostic protocol and troubleshooting wire for fault code P0606 specifically for the Chrysler Voyager (2020–2026, 3.6L Pentastar V6 24V VVT (287HP / 9-Speed Automatic)).
1. Symptoms of P0606 on Chrysler Voyager
When the Engine Control Module (ECM/PCM) on your Chrysler Voyager (3.6L Pentastar V6 24V VVT (287HP / 9-Speed Automatic)) logs fault code P0606, drivers commonly observe:
2. Most Likely Causes on Chrysler Voyager
Historical warranty claims and technical repair bulletins for Chrysler Voyager point to the following failure distribution:
3. Step-by-Step DIY Repair Guide for Chrysler Voyager
Check battery resting voltage (12.6V+) and test alternator for AC voltage leakage (<0.05V AC). High AC ripple destroys ECM logic chips. on the Chrysler Voyager equipped with 3.6L Pentastar V6 24V VVT (287HP / 9-Speed Automatic).
Remove, clean with wire brush, and re-torque all battery negative, engine block, and ECM ground eyelets. on the Chrysler Voyager equipped with 3.6L Pentastar V6 24V VVT (287HP / 9-Speed Automatic).
Disconnect battery, unplug ECM harness plugs, and inspect for bent pins, water moisture, or green corrosion. on the Chrysler Voyager equipped with 3.6L Pentastar V6 24V VVT (287HP / 9-Speed Automatic).
Many manufacturers (such as Toyota and GM) have technical service bulletins providing ECM software re-flashes to resolve false P0606 codes. on the Chrysler Voyager equipped with 3.6L Pentastar V6 24V VVT (287HP / 9-Speed Automatic).
If grounds, voltage, and software are verified but fault persists, replace ECM and program vehicle VIN and immobilizer keys. on the Chrysler Voyager equipped with 3.6L Pentastar V6 24V VVT (287HP / 9-Speed Automatic).

4. Chrysler Voyager P0606 FAQs
What causes code P0606 to trigger on a Chrysler Voyager?
On the Chrysler Voyager (3.6L Pentastar V6 24V VVT (287HP / 9-Speed Automatic)), P0606 is most frequently caused by Corroded or weak ECM main ground connections (especially battery-to-chassis grounds) or Low battery voltage or excessive AC ripple from a failing alternator diode.
Where is the OBD-II port located on my Chrysler Voyager?
On the Chrysler Voyager, the 16-pin DLC diagnostic connector is located Driver lower kick panel near hood release lever. Plug in any standard OBD-II scanner with the ignition in the ON position to read freeze-frame parameters.
Can I safely drive my Chrysler Voyager with code P0606?
No. The vehicle's main engine computer (ECM) has detected an internal hardware/processor calculation fault and may stall or lock in Limp Mode. Given that P0606 carries a Critical severity rating, we advise avoiding heavy towing or aggressive throttle inputs until sensor readings are verified.
