P0054 Chevrolet -

Question

Will using a Bosch O2 sensor instead of Delco replacement cause a P0054 code?

Answer 1

P0054 H02S Heater resitance circuit Bank 1 Sensor 2

This is for the downstream 02 sensor, anytime you replace the 02 sensor on this specific year make and model, you need to clear any code with a scan tool regardless if there is a CK ENG LT on or not, the reason is there, is a 02 sensor resistance relearn reset notice that has to be performed. You do this with a special scan tool, if you do not have it available just clear the CK ENG LT even  if there is no code, what happens is you reset its fuel trim , and its monitor have to run .yes you can use Bosch.
