Order of inspection
P0052 HO2S Heater Resistance (Bank 2 Sensor 1) Medium
The P0052 code means the computer measured the heater resistance of the bank 2 upstream oxygen sensor and found it outside the expected range. It only shows up on V-type or flat (boxer) engines. Most of the time it is a heater element degraded by age, although the wiring and connector can also throw the measurement off.
