DTC P0030 stands for "HO2S Heater Control Circuit (Bank 1, Sensor 1)." P0030 is typically triggered when your vehicle's control module detects problems in the heater circuit in oxygen sensor Bank 1, Sensor 1. You can tell when P0030 is in effect if the check engine light is lit and if your vehicle suffers from decreased fuel mileage. 35002 posts · Joined 2004. #1 · Dec 28, 2018.

The fuse may be labeled gauges, clusters, or something similar. This fuse should have power on both sides with the ignition in the on position. When the PCM detects a possible issue with the heater control circuit on oxygen sensor 2 on Bank 2, it logs code P0056. The code may also be set if the PCM perceives that the oxygen sensor is not heating up properly or if the heater wire is malfunctioning. Depending on the severity, other trouble codes may also be logged, such as P0030 and P0036. .
