GMC Sierra P0138: Oxygen Sensor High Voltage (Bank 1 -Sensor 2)

  P0138 is a common OBDII code that occurs in many vehicles, including theGMC Sierra. The code is triggered when: The voltage at the sensor remains above threshold for 20 seconds or more Voltage to the sensor is to high (wiring problem, think short) Bad O2 sensor itself There are also some less likely problems … Read more
