P2061 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The Code P2061 is to be set up when the Reductant Injection Air Pump fails to perform correctly.
This air pump begins to inject air into the Reductant (DEF) System.

The PCM has recognized a function break down inside the reductant injector air pump control circuit. The reductant injector is utilized to decrease harmful gases that are being released by way of the diesel particulate filter “diesel engines” or catalytic converter “gasoline fueled engines,” and this even applies to the turbocharged.

The reductant injector air pump control system uses sensors inside the exhaust system to input voltage recordings directly to the PCM. These voltage recordings are usually detected by the PCM as exhaust gas temperature or pressure, which depends on the vehicle producer and model. Differences in system voltage that overreach the vehicle producer’s advanced decisions in making any restrictions will result in storing a code and will probably illuminate a service engine soon lamp. A few models need many drive cycles as a way of illuminating a service engine soon lamp.

What causes this problem with the Reluctant Injection Air Pump Control Circuit High?

• Failed reductant air pressure sensor
• Defective reductant injection air pump
• The reductant injection air pressure sensor system has open or shorted circuits
• Negative SCR controller/PCM or programming fault

1. Powertrain Control Module - Intermittent engine behavior may identify a bad or failing ECM.
   A failed computer may result in the vehicle to unexpectedly slow down or fail to expel.
   The symptoms might come and go, also not appear to have any indications of pattern in their frequency or severity. Issues with engine performance are another probability that is associated to the ECM. If the ECM is faced with any issues, it might resist the timing and fuel settings of the engine, which can badly affect the vehicle’s performance. A failed ECM may result in the vehicle dealing with a reduction in fuel efficiency, power, and acceleration. A negative ECM may lead to a vehicle that won’t start or faces challenges in starting. If the ECM fails completely, this will leave the vehicle without engine management control, so it will not start or run as a result. The engine may still be cranking, but without the vital inputs from the computer, it will fail to start entirely.
2. Catalytic Converter - Rattling noises that are coming from underneath the vehicle are an important symptom of a bad or failing catalytic converter. If a catalytic converter is getting older or is damaged from the inside by excessive rich fuel mixtures, the catalyst-covered honeycomb netting from the inside of the converter can collapse or deteriorate, which results in a rattle. The rattle could be more apparent when starting the vehicle and gets even worse overtime. The catalytic converter is built inside the vehicle’s exhaust system, and as a result, can greatly affect on the engine performance if problems are to expand. A blocked converter will restrict the exhaust flow, where a cracked converter is going to be leaking toxic gas. Any of these faults can badly affect the engine performance and lead to a reduction in power and acceleration, as well as the economy of fuel.
3. Air Pump Injector - The air injection pump system is designed to help reduce the emissions that are emitting out the exhaust and can lead to a failing vehicle emission inspection. When the check engine light is turned on, this will cause the vehicle to fail emission examination. The air injection pump must not result in any drive symptoms, all except for a Check Engine Light.
4. Fuel Pressure Sensor - The fuel pressure sensor might be dealing with a probable issue in hard starting. A failed fuel pressure sensor may send an irregular signal directly to the computer, which may result in the engine to undertake hard starting. The engine may put up with a few cranks for a longer period of time than normal to start running and in more severe cases may not start altogether. The vehicle’s fuel pressure sensor also could be dealing with a possible issue in performance.
   A failed fuel pressure sensor may affect the air fuel ratio and lead to the vehicle undertaking performance issues such as reduced power, acceleration, and fuel efficiency, and may even begin stalling.
5. Exhaust Gas Temperature Sensor - A bad or failing EGR temperature sensor might deal with an important symptom like an engine ping or knock. If the EGR temperature sensor fails to perform, this will result in the EGR system flow. This can result in cylinder temperatures to rise up, which can lead to engine ping or knock. Engine ping or knock will make sounds like a metallic rattling noise that is emitted out of the engine bay, and signals a problem with the combustion process. Any problem that results in an engine ping or knock requires attention by an experienced mechanic, as engine knock can result in critical engine damage if left unchecked.

We at Parts Avatar Canada we care about guiding our customers, and this are why we are here to help diagnose the P2061 code by posting a few essential symptoms. They are described below as the following:

Common Symptoms

• Decrease in fuel efficiency
• Vehicle exhaust emits too much black smoke
• Declined engine performance
• Fuel pressure is too high
• Dropped fuel efficiency
• Exhaust is rich or lean
• If not clearing the DPF, this returns the ECU to the Limp Home Mode until correcting the situation

Our team has listed down a few steps that can help you in correcting the incident of OBD Code P2061. They are described below as the following.

• If there is an opening in either the reference voltage or ground circuits, use the digital volt/ohm meter to detect for progression, whereas you disengage all associated control modules from out of the circuit prior to detecting the circuit resistance or controller damage that might happen, and the resistance within all of the circuits.
• This procedure will assist you to find out whether the function crash is irregular or not. Once all the codes have been cleared, have the vehicle test driven to confirm if the code is coming back.
• Many tools will be contributory in diagnosing this code with success.
• If all system circuitry and sensors are inspected and the transmission is performing very efficiently, surmise a defective PCM, but be mindful that a failing PCM is uncommon and replacing the PCM t will need reprogramming.

Our team at Parts Avatar Canada is available to solve all of your problems associated to vehicle components. Our stock is comprised of a vast extension of great prices in PCM, Catalytic Converter, Air Pump injector, Fuel Pressure Sensor, Exhaust Gas Temperature Sensor and so much more to assist you in repairing your vehicle.

If you are eager to simply diagnose this error code, then determine that you need to follow through with these steps, which are described below as follows:

• You might utilize your reference of vehicle data to position a technical service bulletin (TSB) that suits the year, make and model of the vehicle, including the engine size, code(s) being stored, and symptoms that are displayed. If you succeed in finding some data, it can give way to a helpful source of diagnostic data.
• Utilize the scanner that is engaged to the vehicle diagnostic connector to receive the entire storage of codes and relevant freeze frame data. It would be an excellent idea to write down this data prior to clearing the codes and then have vehicle test-driven up until the PCM is either accessing the preparation mode or the code is being set again.
• If the PCM accesses the preparation mode during this period, the code is irregular and might be a lot more complicated to diagnose. In this scenario, the settings given to the code being stored might need to get worse prior to making a consistent diagnosis.
• If the code is instantly set again, proceed with achieving the next step of your diagnosis, in which you will need to seek out your vehicle data reference for diagnostic flow-charts, connector pin-out charts, connector face views, and vehicle part inspection methods/identifications.

Common Mistakes When Diagnosing the P2061

The P2061 OBD2 sends a report to a sensor error, and replacing the sensor is insusceptible  to solving the undertaken issue. The error is most susceptible to be a result of the systems that the sensor is detecting, but may even be the result of the wiring connected to the sensor at its independence.
