i have a 2009 gmc acadia and i get an off and on p0050 code

Question

i only have the one code p0050

Answer 1

HI there,

This code is for the heater circuit on the bank2 heated O2 sensor, sensor 1. Most often the problem is with the sensor itself and not the wiring. This seems most likely in your case where you have it coming and going. Replacing the sensor should resolve the problem.
