Error Code P2083: What It Means & What To Do?

<<See All OBD Codes

Are you looking for information with respect to P2083 error code? Then you are at the right place. Keep reading. P2083 code shows the performance of the engine which is very low and it is defined as the exhaust gas temperature sensor circuit intermittent bank 2 sensor 1. If an unlikely signal is found from the EGT sensor, the PCM will identify it and set the P2083 error code in the vehicle.

The PCM carefully looks after the EGT sensor so that it can maintain the correct continuity of the circuits and as well as the high values that are out of range. You will find the EGTS either in front of the diesel oxidation catalyst or the diesel particulate filter. In order to control the conditions of the engine and to reduce the emission effectively, the EGTS will find the exhaust gas temperature and change it into a voltage where it sends it back to the PCM along with the voltage signal. If the PCM finds out that EGTS is out of factory specification, then it will set the P2083 error code.

What causes this problem with the Exhaust Gas Temperature Sensor Circuit Intermittent Bank 2 Sensor 1?

• Malfunctioning of the EGT sensor bank 2 sensor 1.
• The harness might be open or shorted in the EGT sensor bank 2 sensors.
• The electrical connection of the EGT sensor bank 2 sensor 1 might be poor.
• The exhaust might be leaky.
• The buildup of particulate matteron the sensor might be excessive.

1. Powertrain Control Module - If you find the check engine light on the display dashboard, then the PCM is faulty. Replace it as soon as possible to avoid the P2083 error.
2. Engine Control Module - Is the performance of your engine very poor? Then your ECM can be defective. Get it replaced with a new ECM from PartsAvatar.
3. Exhaust Gas Temperature Sensor - A damaged EGT sensor can likely damage other internal components and cause the failure of the system. Alter the defective EGT sensor as soon as possible.
4. Diesel Particulate Filter - If your vehicle experiences too much power loss, then the diesel particulate filter can be faulty. Replace the damaged DPF quickly to avoid power loss.
5. Diesel Oxidation Catalyst - DOC is nothing but a flow-through the filter which contains precious metals so that the oxidation of hydrocarbons, carbon monoxide, and unburned fuel and oil can be initiated. Do you find the DOC to be faulty? Replace it quickly.

Our main motive is to achieve customer satisfaction and that’s why we will help you to diagnose P2083 code by mentioning some major symptoms below:

Common Symptoms

• Either the engine light or the warning light of the service engine will be on.
• The engine performance will be less.

Have a look at some ways with which you can correct the P2083 code:

• The defective EGT sensor bank 2 sensor 1 must be changed.
• The opening or short circuit in the EGT sensor bank 2 sensor 1 has to be fixed.
• The EGT sensor bank 2 sensor 1, which has a weak electrical connection has to be repaired.
• The leaks in the exhaust must be fixed.
• The excessive particulate matter builds up on the sensor has to be cleared.

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, ECU, diesel oxidation catalyst, diesel particulate filter, RPM, transmission range sensor circuit, and many more. Now all your problems would vanish within no time.

Here are some steps which you should follow in order to diagnose this P2083 fault code:

• The EGT sensor is a 2-wire sensor which is positioned in the exhaust downpipe.
• You will find this EGT sensor utilized in diesel engines, gasoline burning engines, and even turbocharged engines.
• The sensor will likely found near the diesel particulate filter section of the exhaust system in diesel engines.
• Turbocharged applications might fix the EGT sensor in the exhaust input pipe, which is close to the turbocharger.
• The EGT sensor belongs to temperature reactive resistor type.
• Usually, a 5-volt power which is of low voltage is supplied to the power wire and ground wire by the sensor.
• The resistance level in the sensor will decrease as the EGT increases which permit the feedback voltage signal to increase to the PCM.
• The circuit resistance will increase as the exhaust temperature decreases while the engine is turned off which in turns allows the feedback voltage signal to decrease to the PCM.
• The PCM will find these voltage variations as EGT and it responds likewise, by fixing the ignition timing or air/fuel ratio so that the exhaust gas temperature can be reduced and the catalytic converter can be shielded.
• You will need several instruments to effectively diagnose this code.
• A DVOM, an oscilloscope and a scanner can help in performing a successful diagnosis.
• It will be highly helpful if an infrared thermometer with a laser pointer is used.
• Visually inspect the wires and the connectors.
• Repair the separated, eroded and damaged wires, connectors and other parts as needed.
• Retest the system after a successful diagnosis. If every component is in proper working condition, then attach a scanner to the diagnostic connector and recover the stored codes and freeze frame data.
• This step can be highly useful to determine if there are any erratic conditions which made the code to get stored.
• Clear the codes and test the vehicle to see if the error returns.
• This can help you to know if the malfunction was erratic.
• Clear the codes again and test drive to see if the error reappears.
• There might be an erratic condition if the code refuses to return instantly.
• It can be quite challenging to diagnose this error code where at times you have to worsen this condition.
• Visual inspection of the EGT sensor and system circuitry has to be done by continuing the diagnosis.
• Carefully look at the areas where the connectors and wires are placed near the exhaust components that are hot.
• Continue the diagnostic procedure, if the circuit of the EGT sensor appears to be in normal working condition.
• If you find any items to be burnt, defective or eroded, fix them accordingly. If you don’t find any of these defects, then separate the EGTS connector and take away the EGT sensor.
• By using a DVOM, the resistance of the EGT sensor has to be checked.
• Double check the specification by the manufacturer before you test. But the resistance of the sensor must be roughly 150 ohms.
• If the resistance is below 50 ohms, then you must replace them.
• Heat the resistor with the help of a heat gun by leaving the leads of the DVOM as it is if the initial resistance is within the specification.
• Carefully examine the level of resistance of the sensor on the display of DVOM as the temperature will be increased slowly to check if there is a smooth decrease.
• Replace the sensor, if the resistance level does not decrease with heat and rises as it cools.
• Turn the key to ON position and check the voltage and ground signal at the electrical connector of the EGT sensor if everything works perfectly.
• Separate the PCM connector if there is no low voltage and carry out and a continuity test by using a DVOM on the wire.
• Presence of continuity shows that the PCM is faulty which is very rare and has to be replaced or reprogrammed.
• Use a DVOM and check for continuity by finding the source if there is no ground.
• Fix the open or shorted wires and connectors as needed.
• This error can also be stored, if the high-performance exhaust systems are installed with no catalytic converter as there might be a lack of exhaust system back pressure.
• By installing an inline resistor between the signal and ground wire can help you to rectify this condition and the EGT sensor must be left disconnected.
• The sensor resistance will be read by the PCM and passed on.
• Prior to removing the emission-related components, the local, state and federal laws must be checked.

Common Mistakes When Diagnosing the P2083 Code

• Defective exhaust gas temperature sensor.
• Damaged PCM.
• The wires face some issues.
