Where is the oxygen sensor on an 89 dodge ram charger?

The location of the oxygen sensor (O2 sensor) on a 1989 Dodge Ramcharger depends on the engine it has. There's no single answer. The Ramcharger came with several different V8 engines in 1989.

To find it, you'll need to:

1. Identify your engine: Check your vehicle's paperwork or the engine bay itself for an engine identification plate. This will tell you the engine size (e.g., 5.2L, 5.9L).

2. Consult a repair manual: Once you know the engine, find a repair manual specific to your 1989 Dodge Ramcharger and that engine. The manual will have diagrams showing the exact location of the oxygen sensor(s). Most likely it will be in the exhaust manifold or the exhaust pipe relatively close to the exhaust manifold.

3. Use an online parts diagram: Websites like AutoZone, Advance Auto Parts, or RockAuto allow you to select your vehicle's year, make, model, and engine. Their parts diagrams often show the sensor's location.

Without knowing the specific engine, it's impossible to give you a precise location. Be aware there might be more than one O2 sensor, especially if it has a fuel injection system.
