P20CC - OBD Trouble Code

<<See All OBD Codes

Error code P20CC flashing? Don’t know what to do? No worries, Parts Avatar has got you covered. This OBD-II code powertrain control module (PCM) failure is also known as a exhaust aftertreatment fuel injector "A" control performance. It should be noted that the diesel exhaust fluid (DEF) is utilized while converting the remaining exhaust particles to harmless gases. An increased temperature is required to burn off these particles. When the DEF fluid is injected into the exhaust stream, it brings the diesel particulate filter (DPF) up to the temperature. Only then the system is able to alter the dangerous NOx to nitrogen, carbon dioxide and water. The code P20CC is stored, whenever the DEF injector fails to function according to the specifications.

One can observe the exhaust fuel addition injector assembly positioned over the outlet of the turbocharger sub-assembly. Also, the low-pressure fuel is transferred to the exhaust fuel addition injector assembly via the feed pump in the supply pump assembly. When the engine control module (ECM) sends a control signal, fuel is added by the exhaust fuel addition injector assembly. Further, this injector is utilized for two distinct controls including the particulate matter (PM) forced regeneration and PM reduction.

What causes this problem with the Exhaust Aftertreatment Fuel Injector A Control Performance?

• A fault in the exhaust aftertreatment fuel injector
• Loose or shorted exhaust aftertreatment fuel injector harness
• A bad electrical connection in the exhaust aftertreatment fuel injector circuit

1. Powertrain control module - It is because of a fault in the powertrain control module, erratic behaviour of the engine likely to follow besides other issues like a sluggish engine crank, failure in the emission system etc. We advise you to get your faulty PCM changed now by simply logging into Parts Avatar.
2. Diesel exhaust fluid pump - Are you facing issues with equipment, including engine de-rating or shut-down? Well, it is due to bad diesel exhaust fluid pump. In order to get rid of all these problems and the error code P20CC mend or restore your diesel exhaust fluid pump.
3. Exhaust aftertreatment fuel injector - A damaged exhaust aftertreatment fuel injector is likely to trigger problems like a diminished fuel efficiency and a falling engine performance. Now get away with all these issues and the error code P20CC with Parts Avatar. We are just a click away!
4. Fuel injector - Fuel injectors are responsible for injecting the right amount of fuel in the engine. So a damaged one should instantly be replaced. Don’t know where to look for? Parts Avatar provides superior quality fuel injectors just at the prices you have been looking for.
5. Diesel particulate filter - Increased idle speeds? Cooling fans running? Don’t know the reason behind it? Don’t know what to do? Well, it is due to a jammed diesel particulate filter. Get your diesel particulate filter changed with Parts Avatar. Tune into Parts Avatar now for your new diesel particulate filter offered at just the right prices.
6. Ohmmeter - Can’t solve the error code P20CC? Well, you require a good quality ohmmeter to diagnose the error code. So to add some spark to your ride you definitely need the perfect quality ohmmeter offered at Parts Avatar. Isn’t that just the perfect deal?
7. DEF injector - Tired of seeing the error code P20CC flashing? Not only this, a faulty one is likely to arise issues like black smoke emitting out of the vehicle and a fall in the engine performance.

We at Parts Avatar Canada care for our customers, and that’s why we will help you to diagnose P20CC code by listing out some major symptoms. They are mentioned below as follows:

Common Symptoms

• Diminishing engine performance
• Increased black smoke from vehicle exhaust
• Fall in the fuel efficiency
• Various other EAS/SCR related codes

Learn the ways with which you can correct this trouble code:

• Repair or replace a malfunctioning exhaust aftertreatment fuel injector
• Mend or restore a weak electrical connection running in the exhaust aftertreatment fuel injector circuit
• Amendments should be made in order to fix the open or shorted harness in the exhaust aftertreatment fuel injector

However, if you face any issue then we have stocked a wide range of best priced PCM, diesel exhaust fluid, exhaust aftertreatment fuel injector, fuel injector, diesel particulate filter, EAS, ohmmeter, DEF injector, automatic transmission module and more to help you out in fixing your car.

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

• First and foremost, an updated diagnostic scanner, a digital volt/ohmmeter (DVOM) along with a source of vehicle specific diagnostic information should be used to diagnose a code P20CC.
• Finding a technical service bulletin (TSB) that aptly matches the vehicle year, make/ model as well as the engine size, code/s stored, and symptoms displayed helps greatly in extracting helpful diagnostic information.
• Perform a visual inspection of the EAS wiring harnesses and connectors. All the corroded or defective wiring and connectors should be mended or restored.
• Connect the scanner into the vehicle diagnostic connector to retrieve all the stored codes and relevan freeze frame data. It is advised to register all the information before clearing the codes. Also, a test drive of the vehicle should be performed till the PCM either enters readiness mode or the code reappears.
• The code is an intermittent one and may require to worsen (before an accurate diagnosis can be performed) if the PCM enters the readiness mode immediately.
• Also, at times when the code resets immediately, the next step of the diagnosis should be to search the vehicle information source in order to to procure diagnostic flow charts, connector pin-out charts, connector face views as well as the component testing procedures and specifications.
• The vehicle information source should also be used to pinpoint the exact location of EAS fuel injector A.
• Next, the DVOM should be used to test (voltage drop) the power supply to the EAS control system. All the fuses should be examined with the circuit loaded in order to avoid misdiagnosis.
• If you find the required power (battery voltage) and ground circuits are, utilize the scanner to actuate the EAS fuel injector (solenoid) and probe the output control circuit voltage.
• When the voltage is deficient, a damaged controller or a programming error in it should be suspected. Also, if the voltage output circuit falls within the manufacturer’ specifications, use the DVOM to probe the EAS fuel injector. A failure in the injector should be suspected, if it fails to fall within the manufacturer’s specifications.

Common Mistakes When Diagnosing the P20CC Code

Here we have listed only for our customers a few common mistakes that should be avoided while diagnosing the error code P20CC:

• A distorted DEF injector
• A defect in the powertrain control module (PCM)
• Wiring problems
