my Ram 1500 DT (2019-Present) has a check engine light with P0130 code, how do I fix it?

Fix the P0130 code causing check engine light on Ram 1500 DT. Step-by-step guide for diagnosing and replacing the oxygen sensor.

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Disconnect the vehicle's battery to prevent any electrical shorts.
• Ensure the vehicle is on a level surface and secure it with wheel chocks.

2. Remove the Oxygen Sensor

• Locate the upstream oxygen sensor (typically near the exhaust manifold).
• Use an oxygen sensor socket or a wrench to carefully unscrew the oxygen sensor from the exhaust pipe.
• Disconnect the electrical connector of the oxygen sensor by pressing the release tab and pulling it apart.

3. Inspect and Clean the Connector

• Examine the oxygen sensor connector for corrosion, dirt, or damage.
• If necessary, clean the connector with electrical contact cleaner and allow it to dry completely.
• If the connector is damaged, replace it.

4. Install New Oxygen Sensor

• Apply a small amount of anti-seize compound to the threads of the new oxygen sensor (if not pre-applied).
• Screw the new oxygen sensor into the exhaust pipe by hand to avoid cross-threading, then tighten it to the manufacturer's torque specification (usually around 30-35 ft-lbs).
• Reconnect the electrical connector securely.

5. Reconnect Battery and Clear Codes

• Reconnect the vehicle's battery.
• Start the engine and allow it to reach operating temperature.
• Use the OBD-II scanner to clear the P0130 code and any other stored codes.
