P0036 SATURN - HO2S Heater Control Circuit Bank 1 Sensor 2
P0036 SATURN Possible Causes
- Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 fuse
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 harness is open or shorted
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit poor electrical connection
- Faulty Powertrain Control Module (PCM)
How is the P0036 SATURN code repair?Start by checking the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.
What is the cost to diagnose the P0036 SATURN code
Labor: 1.0The cost to diagnose the P0036 SATURN code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.
When is the code detected?The P0036 is set when the PCM detects an open or shorted to ground condition on the heated oxygen sensor heater circuit
- Engine Light ON (or Service Engine Soon Warning Light)
P0036 SATURN MeaningOxygen 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 Powertrain Control Module (PCM).
In order to achieve the require temperature, a heater element is included inside the heated oxygen sensor. The PCM controls the heated oxygen sensor heater element based on signals from the engine coolant temperature and engine load. The PCM controls the heater element circuit by allowing current flow to ground.
The PCM 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.
