Error Code P0205: What It Means & What To Do?

<<See All OBD Codes

Are your vehicle engine performance decreasing and you notice an increase in the fuel consumption? Do you notice the Malfunction Indicator Light illuminated on the dashboard? If there are faults in the fuel delivery system of the car, especially the fuel injector, then P0205 fault code is definitely going to trigger up.

An affected fuel injection system can cause engine misfires, rich and lean conditions. This means that the Powertrain Control Module is not able to interpret the right amount of fuel entering the engine thus hampering the fuel to air ratio, affecting the engine performance. When the PCM detects abnormality in the normal functioning of the fuel injector system and circuit with the voltage and resistance not in the acceptable parameters, the PCM flashes the OBD code P0205 error.

What causes the problem of Cylinder 5 Injector Circuit Malfunction?

• The fuel injector circuit might be open or shorted
• Defective oxygen sensor
• Programming error with the PCM
• Faulty MAF or manifold air pressure (MAP) sensor
• Poor or damaged electrical connection to the wiring harness of the injector circuit
• Leakage in the fuel injector

1. Powertrain Control Module - P0205 code can also display due to some defects in the PCM. So, it is very important to replace the powertrain control module components to get the correct readings. Buy new components form us now!
2. Fuel Pressure Sensor - Inspect the FPS for any faults as it can adversely affect the fuel delivery system and cause performance issues. Replace now!
3. Fuel Injector - Check for leakages and damaged in the fuel injector and get it replace immediately.
4. Engine Control Module - OBD Error Code P0205 can also be due to faulty ECMs. This may lead to engine stalling or not starting, and check engine lights being on. It’s better to get the faulty electricals replaced as soon as possible.
5. Diagnostic Tool - Choose from our wide variety of diagnostic tools to detect and correct the OBD code error.
6. Engine Wiring Harness - Replace faulty engine wiring and harness to avoid any performance problems and to solve this OBD code.

It is important to note the symptoms that can hint towards this kind of problem. Normally the below mentioned symptoms are the first to be noticed and suspect any problem. These can indicate towards definite fuel delivery system problem and thus the engine performance. Lean/rich exhaust conditions are the direct sigh of the air to fuel ratio mismatch with noting the reduced/increased volume of fuel entering the chamber. Thus, the owner must understand that the problem prevails with the delivery system only.

Common Symptoms

• Affected engine performance
• Affected fuel efficiency
• Engine stalling and reduced accelerations
• Issue of lean/rich exhaust codes
• Some misfire codes can also be stored
• Engine running on failsafe mode
• Check Engine Light On

The most common problem in this scenario is the fuel injector which needs replacement. However, it is important for other to be examined also and checked for any faults and damages. Major components that might need replacement are as follows:

• Fuel Injector
• Fuel Filter
• Fuel Pump
• MAF/MAP sensor
• Wiring and connectors

At Parts Avatar Canada, find quality replacement parts form best of brands and competitive prices for all vehicle make and model.

• Contact an experienced mechanic who will visually inspecting the fuel system, searching primarily problem with the fuel injector circuit.
• You will require quality diagnostic tools and equipment to detect and resolve this issue. Make use of factory grade OBD scanner to scan for the existence of a particular OBD error code in the vehicle system. Always test drive the vehicle to see if the code in genuine and returning again or not.
• Freeze frame the data and clear code. Test run the vehicle to see if the code returns.
• Repair or replace the part that is causing the fuel injector circuit malfunction, once the source of the problem has been found.
• Check for any wiring and harness issues and correct the damaged, corroded or short wirings.
• If no problem is found, then check for the faulty ECU. Although, this fault is very rare but can be a reason for problematic fuel delivery system, thus hampering the engine performance. The ECU needs to be replaced in such condition and has to be reprogrammed to erase any stored faulty error.

Common Mistakes When Diagnosing The P0205 Code

• Mistakes can easily be made by anyone if they skip steps or do not complete all steps required.
• These steps should always be followed to avoid unnecessary repairs, and save time and money
