P0036 LAND-ROVER

P0036 LAND-ROVER - HO2S Heater Control Circuit Bank 1 Sensor 2

Repair Importance Level: 2/3
Repair Difficulty Level: 2/3  What does this mean?

P0036 LAND-ROVER 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 Engine Control Module (ECM)

First diagnose P0036 LAND-ROVER code

    Check 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 terminals.

P0036 LAND-ROVER Tech Notes

The code means that there is a problem with the heater element circuit of the heated oxygen sensor. The control module monitors how long it take the sensor to warm up and start sending an adequate signal. The code is triggered when the sensor is taking too long to warm up. Water getting inside the heated oxygen sensor connector can caused the heated oxygen sensor fuse to blow. Before replacing the sensor, check for the condition of the heated oxygen sensor fuse and connectors. If the sensor and connector are OK, replacing the O2 Sensor 1 usually takes care of the problem

HO2S Heater Control Circuit Bank 1 Sensor 2 is the generic definition for the P0036; however your vehicle's manufacturer may have a different definition and information for the P0036 code.

Cost of diagnosing the P0036 LAND-ROVER code

    Labor: 1.0

    The cost of diagnosing the P0036 LAND-ROVER 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 P0036 LAND-ROVER code detected?

The P0036 is set when the ECM detects an open or shorted to ground condition on the heated oxygen sensor heater circuit

P0036 LAND-ROVER Possible Symptoms

  • Engine Light ON (or Service Engine Soon Warning Light)

P0036 LAND-ROVER Meaning

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.
