Reset the ecu,

Check for a 5 volt reference signal at the wiring to the knock sensor. With key on engine off one of the wires to the sensor should have 5 volts.
SOURCE: 2007 gas cap light comes on then the ckeck engine
maybe they got a malfunctioning sensor it happens go back
SOURCE: Odometer not working
yes the speed sensor controls the speedometer and odometer and they are electrical no more drive cable installed
SOURCE: P0037 code subaru outback I have replaced the cat and both o2 sensors and the same code comes up
I'm sorry you spent that money if this was the original code.
The code means one of the O2 sensors has a faulty heater or the power circuit for the heater is bad. The sensor is not heating up as fast as it should. Since you have replaced the sensor you would need to check the power circuit for the heater.
P0037 SUBARU Description
Oxygen Sensors (O2S) or Heated Oxygen Sensors (HO2S) need to reach a
minimum operating temperature of 750 degrees F to produce an accurate
voltage signal. The faster the heated oxygen sensor reaches that
temperature the faster the sensor will start sending an accurate signal
to the Engine Control Module (ECM).
In order to achieve the require temperature, a heater element is included inside the heated oxygen sensor. The ECM controls the heated oxygen sensor heater element based on signals from the engine coolant temperature and engine load. The ECM controls the heater element circuit by allowing current flow to ground.
The ECM
monitors the voltage signal received through the heater element circuit
and determines the state of the circuit by comparing the voltage
detected with the factory specifications.
