my Ram 1500 DT (2019-Present) is showing P0130 code, what does that mean?

Learn how to diagnose and fix P0130 oxygen sensor circuit malfunction in Ram 1500 DT. Step-by-step guide with diagnostic procedures and repair instructions.

Solution

1. Preparation

• Gather all necessary tools and parts.
• Disconnect the battery to ensure safety while working on electrical components.

2. Remove the Oxygen Sensor

• Locate the Bank 1 oxygen sensor (typically found in the exhaust manifold or upstream of the catalytic converter).
• Use an oxygen sensor socket or a wrench to carefully unscrew the sensor from its position.
• Disconnect the electrical connector from the oxygen sensor.

3. Inspect and Clean

• Inspect the sensor's wiring and connector for any signs of wear, damage, or corrosion. Clean any corrosion with electrical contact cleaner.
• If the wiring is damaged, repair or replace it before installing a new sensor.

4. Install New Oxygen Sensor

• Apply anti-seize compound to the threads of the new oxygen sensor (if recommended) to ensure proper installation.
• Screw in the new oxygen sensor and tighten it to the manufacturer's specified torque (typically around 30 ft-lbs but verify for your specific part).
• Reconnect the electrical connector to the oxygen sensor.

5. Reconnect Battery and Test

• Reconnect the vehicle's battery.
• Clear the trouble codes using the OBD-II scanner and start the engine.
• Allow the engine to reach operating temperature and monitor the oxygen sensor readings using the scanner.
