P20CA OBD Error Code: Problem & Solutions

<<See All OBD Codes

Check engine light flashing? Don’t know what to do about it? Don’t worry, Parts Avatar has a solution for all your problems! Here’s all you need to know about the error code P20CA. In order to convert the leftover exhaust particles to harmless gases, the diesel exhaust fluid (DEF) is utilized. One should increase the temperature of the exhaust system in order to burn off those particles. Also, the temperature of diesel particulate filter (DPF) is brought up to the level using the injection of DEF fluid into the exhaust stream. This further enables the system to convert harmful NOx to nitrogen, carbon dioxide and water.

It should be noted that, to reduce the remaining NOx in the exhaust stream, the reductant catalyst (SRC) is added. This reductant pressure sensor enables the engine computer to regulate pressure in the diesel particulate filter (DPF) system. The code P20CA is stored, when if the sensor transmits back an impractical signal.

What causes the problem with the Reductant Injection Air Pressure Leakage?

• A failure in the catalytic converter
• A possible fault in the DPF regeneration

1. Diesel exhaust fluid pump - A bad diesel exhaust fluid pump can be host to equipment issues including increased consumption of the components installed. We advise you to get yours changed right away with us.
2. Exhaust system parts - See the error code P20CA? Well, it could be due to malfunctioning exhaust system parts. In addition to the error code P20CA, the driver is likely to experience a noisy engine, decrease in power and acceleration. We strongly recommend to get your exhaust system parts changed or repaired form Parts Avatar.
3. Diesel particulate filter - Observing soot building up? Increased idle speed? A slight increase in the fuel consumption? It should be noted that all these problems occur due to a blocked or completely damaged diesel particulate filter. We advise you to mend it or restorer it as soon as possible to get rid of all these problems.
4. Powertrain control module - A distorted powertrain control module? Do you have any idea about the extent to which it can damage your system? A jammed powertrain control module brings along issues like a malfunction in the functioning of the entire engine, also the sparks and ignition timing from the spark plugs are controlled and received by the PCM. So to avoid a whole lot of repairs, we simply advise you to change your PCM now. Log into Part Avatar for best quality PCMs at the best prices.
5. Reductant pressure sensor - A defective reductant pressure sensor is likely to bring along problems like a fall in the fuel efficiency, excessive black smoke coming out from the vehicle’ exhaust and a bad engine engine performance. Log into Parts Avatar for your new reductant pressure sensor available at just the right prices.

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P20CA here:

Common Symptoms

• A failure in the DPF regeneration (may not appear)

Here are some ways with the help of which you will be able to correct the OBD Code P20CA:

• In order to correct the OBD error code P20CA it is essential to repair or replace the malfunctioning DPF regeneration
• Replacements or repairs should be performed of a defective catalytic converter

There is no need to be anxious as Parts Avatar – Car Parts Online is here to help you out! We have high grade DEF, exhaust system, diesel particulate filter, PCM, reductant pressure sensor, def fluid, particle filter, pcm module and a lot more for our precious customers.

A scanner (or code reader) and a digital volt/ohmmeter will be helpful in successfully diagnosing this code-storing condition.Begin your diagnosis with a visual inspection of system wiring, connectors, and components.Repair or replace any open, shorted, damaged, or corroded items as required and retest the system to make sure that repairs were successful. If the system wiring, connectors, and components appear to be in normal working order, connect the scanner to the diagnostic connector and record all stored trouble codes and freeze frame data.This information can be extremely helpful in diagnosing intermittent conditions that may have contributed to this code being stored. After the codes are cleared, operate the vehicle to see if the code returns. If the code fails to immediately return, you may have an intermittent condition.

Common Mistakes When Diagnosing the P20CA Code

Well, in order to perform an accurate diagnosis, it is important to avoid certain mistakes. Only for our customers, we have listed here a few common mistakes that should be avoided while diagnosing the error code P20CA:

• A failure in the powertrain control module (PCM)
• A possible fault in the reductant pressure sensor
• Wiring issues in the system
