Error Code P2212: What It Means & What To Do?
OBD Code P2212 - NOx Sensor Heater Sense Circuit Intermittent Bank 1
Are you looking for information with respect to
the P2212 error code? Then you are at the right place. The leftover exhaust
particles are converted into harmless gases with the assistance of diesel
exhaust fluid that is DEF. The temperature of the exhaust system has to be
increased in order to burn off the leftover exhaust particles. As you inject
the DEF fluid into the exhaust system, it will raise the diesel particulate filter
(DPF) up to the required temperature. The injurious NOx is converted into
nitrogen, carbon dioxide, and the water by the system

If there are any NOx present in the exhaust stream, it will be reduced by adding the reductant catalyst. By utilizing the NOx sensors, the engine computer will determine the reductant systems’ performance. The improper functioning of the NOx sensor will set the P2212 error code in the vehicle.
With the help of data that is added from the upstream and downstream oxygen sensors of the vehicle that is joint with the NOx sensor reading, the ECM will be able to compute the amount of nitric oxide and nitrogen dioxide gases present. This is done by the ECM to control the NOx levels which comes out of the tailpipe for sending it out to the environment. Bank 1 signifies the engine bank which has cylinder 1. NOx sensor heater sense circuit intermittent bank 1 refers to the P2212 error code which means that the inconsistency in the overall functioning of the NOx sensor heater sense circuit has been found by the ECM.
What causes this problem with the NOx Sensor Heater Sense Circuit Intermittent Bank 1?
- Defective catalytic converter.
- Fuel mixture might be inappropriate.
- Damaged coolant temperature sensor.
- Defective manifold air pressure sensor.
- The mass air flow sensor might have some issues.
- Broken fuel injection parts.
- Fuel pressure regulator might be damaged.
- There might be conditions of misfiring of the ignition.
- The exhaust manifold, flex hose, downpipe, and other exhaust components might be leaky.
- Malfunctioning oxygen sensor.
Replace/Repair These Parts To Fix OBD Code P2212
- Diesel Exhaust Fluid - More pollution or dust will
get accumulated in the exhaust if the DEF is dirty or murky. Get rid of
the dirty DEF as soon as possible.
- Diesel Particulate Filter - If the DPF is damaged, then
the fuel economy will be very low. Get rid of the faulty DPF to avoid
P2212 error.
- Powertrain Control Module - Any corrosion or break in
the internal wiring harness can cause a short in your PCM. If you’re PCM
is shorted, then you must change the powertrain control module (PCM) as
soon as possible to avoid the P2212 error code.
- Engine Control Module - Overheating of the ECM can
likely damage your ECM. Change it quickly by getting a new ECM from
PartsAvatar.
- Nitrogen
Oxide Sensor - A very poor engine
performance is a sign that the NOx sensor is damaged. Fix the damaged NOx
sensor instantly.
- Catalytic Converter - A damaged catalytic converter will show signs
of failing when the engine misfires. Get rid of it immediately by
replacing it with a new catalytic converter.
- Coolant Temperature Sensor - The fuel economy will be
very poor if the coolant temperature sensor is faulty. Replacing it
instantly can help you to avoid the P2212 error code.
- Air Pressure Sensor - Hesitation of the engine to
start during acceleration is a sign of a damaged air pressure sensor. Get
rid of it as soon as possible.
- Mass Air Flow Sensor - The common symptom that you will notice as a
result of a damaged MAF sensor is the lean idling of the engine. Avoid the
P2212 error by fixing the faulty MAF sensor.
- Fuel Injection Parts - The performance of the engine will be poor and
the vehicle will start surging if the fuel injection parts are damaged.
Replace it with a new one by shopping them from PartsAvatar.
- Fuel Pressure Regulator - Engine stalling is a common
symptom for a defective fuel pressure regulator. Get rid of it as soon as
possible.
- Flex Hose - Do you find any cracks in the hoses? Then it
is a sign that the flex hose is damaged and it needs replacement.
- Oxygen Sensor - The very first symptom that you will notice as
a result of a faulty oxygen sensor is the illumination of the CEL (check
engine light). Fixing this issue can help the vehicle to function
normally.

How To Correct NOx Sensor Heater Sense Circuit Intermittent Bank 1 Issue?
We have listed out so ways which would help you to correct the occurrence of OBD Code P2212. They are mentioned here as follows:
- NOx sensor needs alteration.
- Electrical components needs replacement.
- Upstream or downstream oxygen sensor must be altered.
- The components which caused the malfunctioning of the catalytic converter, as well as the damaged catalytic converter, must be changed.
There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of PCM, exhaust gas, oxygen sensors, indicator lamp, MIL and many more. Now all your problems would vanish within no time.
Easy Diagnosis Of Engine Error OBD Code P2212
If you
want to easily diagnose this fault code, then all you have to do is to follow
the steps which are mentioned below:
Step1: As a
first step, the error code must be cleared and the vehicle must be re-scanned.
Take the
vehicle for a lengthy multi-stop and test drive the vehicle to see if the error
still shows up if there are no diagnostic trouble codes.
If the
ECM has reactivated only one error code, then proceed the diagnostic process
for that specific code.
Step2: Check
for any leakages in the exhaust system. The exhaust system can be leaky if you
find any cracks or black soot around it.
This
issue must be fixed immediately and in most cases fixing a faulty exhaust
gasket is very easy.
A fully
sealed exhaust is highly essential to the sensors as they are included in the
exhaust system.
Step3: Monitor
the exhausts’ temperature before and after the catalytic converter with the
help of an exhaust gun.
You will
need a specific service manual as you must compare the result with that of the
manufacturers’ specification.
Step4: If the
temperature of the catalytic converter is in place with the manufacturers’ specification,
then you must inspect the sensors that are included in the electrical system.
Start
checking the harness and connector of NOx sensor of bank 1.
In most
cases, the harness might get cracked or damaged as they lie very close to the
extreme temperatures of the exhaust.
The
damaged wires have to be replaced by soldering the terminals and heat shrinking
them.
The
oxygen sensor at the bank 1 must also be checked to make sure it is not
defective which can eventually change the NOx readings downstream.
Connectors
which don’t have a proper connection or if they are faulty, it must be repaired
quickly.
Common
Mistakes When Diagnosing the P2212 Code
- NOx
sensor might be faulty.
- PCM might
be defective.
- There
might be some faults with the electrical wires.
