What color is the O2 sensor wire on a Dodge Neon?

There's no single answer to what color the O2 sensor wire is on a Dodge Neon. The color coding varies depending on the year, engine, and even sometimes the specific sensor location (bank 1, bank 2, etc.). You'll need to consult a wiring diagram specific to your Neon's year and engine.

To find the correct information:

1. Find your Neon's year and engine code: This information is usually found on a sticker inside the driver's side doorjamb or in your owner's manual.

2. Find a wiring diagram: You can try searching online for "[Your Neon's Year] [Your Neon's Engine Code] wiring diagram" or using a repair manual specific to your vehicle. Repair manuals (like those from Haynes or Chilton) are a great resource for this kind of detail.

Don't rely on generic color codes; they're unreliable and could lead to misdiagnosis or damage. Use a proper wiring diagram for your specific vehicle.
