What is code P0037 mean?
The P0037 code is set when the ECM detects that the HO2S2 on bank 1 has a malfunctioning heater element. The heater in the oxygen sensor helps get the sensor up to operating temperature faster in order to improve fuel economy and emissions.
What does P0137 mean?
P0137 is the OBD-II generic code indicating the O2 sensor for bank 1 sensor 2 is failing to increase the voltage output above . 21 volts indicating excessive oxygen in the exhaust.
