What are the p0141 and p0161 oxygen sensor codes?
P0161: HO2S Heater Performance Bank 2 Sensor 2. Remember, these downstream oxygen (O2) sensors are also known as: post catalytic converter oxygen sensors or Rear oxygen sensors. Before you start testing/troubleshooting Codes P0141 and/or P0161, I highly recommend that you take a look at the following oxygen sensor test primer:
What to look for in a GMC p0161 code?
Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. What does this mean? The cost to diagnose the P0161 GMC code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type.
How long does it take to diagnose p0141 GMC code?
If the sensor and connector are OK, replacing the O2 Sensor 1 usually takes care of the problem. The cost to diagnose the P0141 GMC code is 1.0 hour of labor.
What does DTC code p0141 stand for?
Code P0141 occurs when the powertrain control module tests the downstream heated oxygen sensor’s heater circuit on Bank 1 and detects a short in the circuit or excessive resistance in the heater circuit. This Diagnostic Trouble Code (DTC) does not need to be attended to immediately, but this DTC could result in more costly repairs in the future.

What does p0141 mean in Powertrain Control Module?
Code P0141 occurs when the powertrain control module tests the downstream heated oxygen sensor’s heater circuit on Bank 1 and detects a short in the circuit or excessive resistance in the heater circuit. P0141 Symptoms Check Engine Light is on
How to troubleshoot p0135, p0141, and p0161 DTCs?
Troubleshooting DTCs P0135, P0141, P0155, P0161 is not hard and in this tutorial, we’ll look at some of the basics you need to know and what tests you need (to solve the oxygen sensor problem these diagnostic trouble codes indicate).
