All OBD Codes
Is your car’s
Check Engine Light On? Is the engine hesitant or stumbling? Are you
experiencing increased fuel consumption and loss of acceleration? All these are
the indicatives of OBD Code P0062 error flashing.
Trouble code
P0062 indicates that the heater circuit used to warm up an oxygen sensor has
malfunctioned. A voltage ranging from 12.0-13.5 and a ground connection is
required to operate the oxygen sensor.
Learn More About OBD Error Code P0062
The
oxygen sensor uses a heated circuit to warm up the sensor for faster feedback
operation to the PCM. The oxygen sensor may have three or four wires according
to different make and model, two are used for feedback to the Powertrain
Control Module (PCM) / Engine Control Module (ECM) and the other wires for the
heater to power the heated circuit.
The
code is commonly due to the oxygen sensor not receiving the proper power or
ground needed to successfully control the heater element inside of the oxygen
sensor. An oxygen sensor has a small circuit within it which may lose the
ability to produce heat. The oxygen sensor is part of, and is connected to a
circuit that is used to heat the oxygen sensor.
For
the oxygen sensor to work properly it has to reach a temperature around 600
degrees Fahrenheit. If the sensor does not reach such temperatures the air-fuel
ratio readings will be incorrect. When the PCM detects the heater, wire is not
working properly, it will set code P0062.

Easy Diagnosis Of Engine Error OBD Code P0062
Always
use professional OBD scan tools to verify the code and start the diagnosis
process. An experienced technician should be appointed to do the diagnosis.
Following are the steps to diagnose OBD Code P0062 error.
- Inspect
the power supply and ground of the oxygen sensor.
- Use a
professional scan tool to monitor feedback from the oxygen sensor.
- Checks
for increased temperature of the oxygen sensor when it is removed from the
exhaust.
- Unplug
the oxygen sensor and use a digital voltmeter (DVOM) to test the resistance of
the heater circuit using a wiring diagram for reference.
- Some
resistance should be present inside the heater circuit, and an excessive
resistance or an over limit reading indicates an open in the heated portion of
the circuit, indicating replacement of oxygen sensor.
- Check
for power to supply at the oxygen sensor by back-probing the power supply wire
at the connector with the DVOM set to DC volts with the positive lead on the power
supply wire and the negative lead at a good known ground.
- Clear
the codes and test drive the vehicle to ensure that the repair was successful
and the OBD is not flashing back.
- If
all the components are fine, the PCM can be faulty and may require replacement
or reprogramming.
Common Mistakes When Diagnosing The P0062 Code
- Terminals
of the oxygen sensor not cleaned
- Oxygen
sensor power and
ground supply not checked before replacing the sensor
- Misidentifying
faulty oxygen sensors
- Leaking oil or coolant damaging oxygen sensor
- Not
using vehicle make and model specific sensors
