What is the P0137 Error Code?

The P0137 code is a generic powertrain code common in vehicles, including the Nissan Rogue. It specifically points to "O2 Sensor Circuit Low Voltage (Bank 1, Sensor 2)." This error code is triggered when the Engine Control Module (ECM) detects that the voltage of the oxygen sensor is below a specific threshold for a certain period.

Key Points About P0137:

  • Sensor Involved: Bank 1, Sensor 2. This is the oxygen sensor located after the catalytic converter.
  • Low Voltage Issue: Indicates that the sensor is not operating at optimal efficiency, possibly due to being faulty or contaminated.

Common Symptoms of P0137 in Nissan Rogue

When the P0137 code is triggered, you might notice several symptoms:

  • Check Engine Light: This is the most common and often the first indication that something is wrong.
  • Poor Fuel Economy: Since the oxygen sensor helps regulate fuel mixture, a fault can lead to inefficient fuel consumption.
  • Rough Idling: You might notice that your Rogue is running rougher than usual, especially at idle.
  • Emission Problems: Increased vehicle emissions, which might cause your vehicle to fail emissions testing.

Diagnosis and Repair:

  1. Scan and Verify: Use an OBD-II scanner to confirm that P0137 is the only code present. If other codes are present, they should be addressed first.

  2. Inspect the Oxygen Sensor: Check the sensor for any visible signs of damage or contamination. Look for cracks, broken wires, or signs of oil or carbon buildup.

  3. Check the Wiring: Inspect the wiring harness leading to the oxygen sensor. Look for signs of wear, tear, or corrosion. Repair any damaged wires.

  4. Voltage Check: Use a multimeter to check the voltage reading of the oxygen sensor. It should fluctuate between 0.1 and 0.9 volts when the engine is running. A constant low voltage might indicate a faulty sensor.

  5. Replace the Sensor: If the above steps indicate a faulty oxygen sensor, replace it. Ensure you choose the correct sensor based on your Nissan Rogue model and engine type.

  6. Clear the Code: After replacing the sensor, use the OBD-II scanner to clear the P0137 code. Then, drive your vehicle for a few miles to see if the code reappears.

  7. Further Inspection: If the problem persists, further diagnostics might be necessary to check for issues with the ECM or other components of the emission system.
