DTC P0036: Rear Heated Oxygen Sensor (HO2S) Heater Circuit Malfunction
DTC P0037: Rear Heated Oxygen Sensor (HO2S) Heater Circuit Low
ECM determines fault exists, sets DTC P0036, P0037 or P0038 and turns the MIL on when during 2 driving
cycles front HO2S heater resistance is less than 4.5 ohms or more than 19.5 ohms.

DTC P0325: KNOCK SENSOR CIRCUIT MALFUNCTION (BANK 1)
ECM determines fault exists, sets DTC P0325 (MIL will not turn on) if during 2 consecutive drive cycles the knock sensor's output voltage drops to less than .65 volt. This indicates an unexpected vibration is being read by knock sensor or ECM under normal engine operation.
Probable Cause
- Open or short to ground between ECM and knock sensor.
- High resistance between ECM and knock sensor.
- Faulty knock sensor.

Опять же для начала: Ensure knock sensor is tightened to 11-18 ft. lbs. (15-25 N.m). An improperly tightened sensor can cause a faulty signal.
Ну и цепь его прозвонить не помешает.
