Code P0032 2002 Renault Master

2002 Renault Masterhello
i am having trouble with my renault master 2.2 2002 starting
i have had it on a computer in a garage and it came up with
I was wondering if you could possibly tell me
A little more about this ..
where it is located …
what it is …
and can i buy and fit it myself
thank you very much


The Code P0032 is set when the ECM detects an excessively high voltage through the heated oxygen sensor heater circuit

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.

Code P0032 Possible Causes

– Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1
– Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 harness is open shorted to ground
– Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 circuit poor electrical connection
– Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 circuit fuse
– Faulty Engine Control Module (ECM)
