P0153 2017 GMC Sierra Code - HO2S Slow Response Bank 2 Sensor 1
Quick Answer
The Heated Oxygen Sensors (HO2S) are used for fuel control and catalyst monitoring. Common causes include Faulty Heated Oxygen Sensor (HO2S) Bank 2 Sensor 1, Heated Oxygen Sensor Bank 2 Sensor 1 harness is open or shorted, Heated Oxygen Sensor Bank 2 Sensor 1 circuit poor electrical connection. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P0153 2017 GMC Sierra Description
The heating elements inside each HO2S heat the sensor to bring the sensor up to operating conditions faster. This allows the system to enter Closed Loop earlier and the ECM to calculate the air-to-fuel ratio sooner.
The Diagnostic Trouble Code (DTC) will be set when the ECM detects that the HO2S 1 rich-to-lean or lean-to-rich average response time is greater than a calibrated value for greater than 60s.
What are the Possible Causes of the DTC P0153 2017 GMC Sierra?
- Faulty Heated Oxygen Sensor (HO2S) Bank 2 Sensor 1
- Heated Oxygen Sensor Bank 2 Sensor 1 harness is open or shorted
- Heated Oxygen Sensor Bank 2 Sensor 1 circuit poor electrical connection
- Low or high fuel system pressure
- Fuel contamination
- Faulty fuel injectors
- Exhaust gas leaks
- Engine vacuum leaks
How to Fix the DTC P0153 2017 GMC Sierra?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.

Frequently Asked Questions about P0153 2017 GMC Sierra Code
What does the OBDII code P0153 mean on a 2017 GMC Sierra?
P0153 indicates that the oxygen sensor (HO2S) on Bank 2 Sensor 1 is taking too long to respond to changes in the air-fuel mixture, suggesting a slow response issue.
What are the symptoms of a P0153 code on a 2017 GMC Sierra?
Common symptoms include the check engine light turning on, reduced fuel efficiency, rough idling, or hesitation during acceleration.
What causes the P0153 code on a 2017 GMC Sierra?
Potential causes include a faulty oxygen sensor, exhaust leaks, wiring issues, or an engine running too rich or too lean.
How can I fix the P0153 code on my 2017 GMC Sierra?
Repairs may involve replacing the Bank 2 Sensor 1 oxygen sensor, repairing exhaust leaks, checking and repairing wiring, or addressing fuel mixture issues.
Which oxygen sensor is Bank 2 Sensor 1 on a 2017 GMC Sierra?
Bank 2 Sensor 1 is the upstream oxygen sensor on the side of the engine with cylinder 2 (passenger side).
Can a dirty mass airflow (MAF) sensor trigger the P0153 code?
Yes, a dirty or faulty MAF sensor can cause air-fuel mixture problems, which may lead to a slow response from the oxygen sensor.
Is it safe to drive with a P0153 code on a 2017 GMC Sierra?
Driving with this code may not immediately harm the vehicle, but prolonged driving can lead to reduced fuel efficiency, increased emissions, or damage to other components.
What tools are needed to diagnose the P0153 code?
A diagnostic scanner, multimeter, and potentially a smoke machine to check for exhaust leaks are useful tools for diagnosing the issue.
How much does it cost to repair a P0153 code on a 2017 GMC Sierra?
The cost depends on the issue. Replacing the oxygen sensor typically costs $150-$400, while repairs for wiring or exhaust leaks may vary.
Can bad fuel cause a P0153 code?
Yes, poor-quality fuel can affect combustion and air-fuel ratios, potentially causing slow oxygen sensor response times.
