P1153 – Insufficient HO2S Switching, Bank 2 Sensor 1

Error Code P1153: Problems and Solutions

Meaning of Code P1153

Code P1153 is related to the Heated Oxygen Sensor (HO2S), Bank 2 Sensor 1.

The Powertrain Control Module (PCM) monitors the heated oxygen sensor activity over a period of 100 seconds. During this time, it counts the number of times the sensor switches from a rich to a lean mixture and vice versa.

  • A switch from lean to rich occurs when the sensor voltage goes from less than 300 mV to more than 600 mV.
  • A switch from rich to lean occurs when the sensor voltage goes from more than 600 mV to less than 300 mV.

If the sensor does not respond correctly or the number of switches is insufficient, the PCM triggers code P1153.

Possible Symptoms

  • Check Engine light on (or “Service Engine Soon” warning light).
  • Excessive fuel consumption.
  • Possible misfires.
  • Poor engine performance.

Possible Causes

  • Faulty Heated Oxygen Sensor (HO2S) (Bank 2, Sensor 1).
  • Open or shorted sensor wiring harness.
  • Poor electrical connection in the sensor circuit.

How to Fix Code P1153?

  1. Visually inspect the wiring harness and associated connectors.
  2. Check for damaged components (burned wires, melted insulation, etc.).
  3. Inspect the connectors for broken, bent, pushed out, or corroded pins.
  4. Test the oxygen sensor voltage with a multimeter:
    • Check if the voltage oscillates between 0.1V and 0.9V when the engine is running.
    • If the voltage remains stuck, the sensor may be faulty.
  5. Replace the heated oxygen sensor if necessary.

If the problem persists after these checks, further diagnosis by a professional may be required.

P1153 BUICK – Insufficient HO2S Switching, Bank 2 Sensor 1

P1153 BUICK – Diagnosis and Solutions

🔧 Possible Causes
⚠️ Issues to investigate:

  • 📡 Faulty HO2S Sensor (Bank 2, Sensor 1)
  • 🔌 Damaged Wiring Harness (open or short circuit)
  • 🔋 Faulty Electrical Connection (corrosion, broken pins)

🛠️ Repair Procedure
🔄 Key steps to resolve code P1153:

  1. 🔍 Visual Inspection:
  • Check the HO2S wiring and connectors (look for corrosion, cut wires).
  1. 🧪 HO2S Sensor Test:
  • Measure sensor voltage with a multimeter (expected values: 300 mV to 600 mV).
  1. 🔄 Transition Check:
  • Use a diagnostic tool to check the number of rich/lean switches over 100 seconds.
  1. ⚡ Replacement/Repair:
  • Replace the HO2S sensor or repair the wiring harness if necessary.

🚨 Common Symptoms
❗ Warning signs:

  • 🚦 Check Engine Light On
  • 📉 Abnormal Air-Fuel Mixture (increased consumption, unstable idle)

📖 Meaning of Code P1153
🔌 Technical explanation:

  • The PCM detects insufficient switching of the HO2S (Bank 2, Sensor 1) between rich (>600 mV) and lean (<300 mV) states for 100 seconds.
  • 📉 This fault disrupts air-fuel mixture control, affecting emissions and performance.

⚠️ Important Tips

  • 🔧 Check the Heater Circuit: A faulty HO2S can also be caused by a defective heater element.
  • 📲 Use an OBD2 Scanner to observe real-time sensor data and validate transitions.
  • 🔄 After repair, clear the code and test the vehicle to confirm resolution.
