Error Code P050D: What It Means & What To Do?
OBD Code P050D - Cold Start Rough Idle
Do
you know when your engine will experience a rough cold start? If your answer is
No, then just give a read. A rough idle will be created if the PCM receives
inaccurate engine temperature signal due to inadequate fuel delivery or wrong
timing. There may be an ECT sensor code stored. You have to repair the ECT
sensor related codes before diagnosing with P050D.

The
idle RPM level is managed by the PCM (Powertrain Control Module). To complete
this task, the intake airflow must be controlled during closed conditions of
the throttle. With the help of an Idle air control (IAC) valve, the PCM will
regulate the engine intake air during idle. If the air is sent into the engine,
it will result in rough engine idle during cold start and P050D will be stored.
Diagnose and repair other codes like lean exhaust or IAC related codes before
proceeding with P050D code. Engine misfire can also be one of the reasons for
idle start condition. If there are misfire codes, they must be diagnosed.
What causes this problem with
Cold Start Rough Idle?
- Leaks
in the vacuum or air intake regions
- Spark
plugs, plug boots and ignition coils are very poor
- Fuel
pressure / Volume is not sufficient
- Shorted
ECT sensor or open circuit and damaged connectors
Replace/Repair These Parts To Fix OBD Code P050D
- Spark Plugs - Does your engine misfire? Then it?s
because of faulty spark plugs. Replace with new ones.
- Plug Boots - Another reason for engine
misfire is an ignition boot failure. Replace the faulty plug boots or fix the
damages.
- Ignition Coils - Ignition coil helps to transform the
voltage as per the engine?s requirement. The component has to be replaced of
there are damages.
- Fuel Pressure
Sensor - A
good fuel pressure will rise to the required pressure level. If not the leaks
or damages have to be repaired.
- Circuits/connectors - Are there any
shorted or open circuit? Is the connectors of your vehicle broke? Resolve the
issue and get them fixed.
Symptoms Of OBD Error Code P050D
Interested
in knowing the symptoms to OBD code P050D? If yes, then you have arrived at the
right place. We at Parts Avatar have listed out few common symptoms associated
with Cold Start Rough Idle.
Common Symptoms
- Cold
Start while driving
- Other
error Codes related to drivability
- The
engine produces Hissing or Sucking Noise
How to correct P050D Cold Start Rough Idle
Have
a look at some ways with which you can correct the P050D code:
- If you want to accurately diagnose the P050D code, then you need the information of diagnostic flowcharts, wiring diagrams, connector face views, connector pinout charts, and component testing processes and conditions. Recover all the stored codes and freeze frame data where you have to connect the scanner to the diagnostic port of the vehicle. Write down this information as it can help with diagnostic process. Clear the codes, allow the engine to cool and test drive again. If the code is not returned and the PCM enters readily then there might be a broken code. Some you have to store the code and allow the engine to worsen before any diagnosis can be made. If the code appears soon, check the factors which impacts the cold start of the engine.
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 Air intake, Spark Plug, Plug Boots, Ignition Coil, Fuel Pressure Circuits or Connectors many more. Now all your problems would vanish within no time.
Easy Diagnosis of Engine Error Obd Code P050D
In
order to diagnose the OBD error code P050D you have to follow a few steps as
follows:
- If
there is too much of air in the intake, when it requires a rich fuel mixture
will create a rough idle. Check for leaky areas in the vacuum.
- There
should be no cracks or damage in the vacuum hose and line.
- Check
for hissing and sucking noise around the throttle body, Intake Manifold Gasket,
Brake Booster and The PCV Valve.
- There
should be no cracks or holes in the Air intake hose.
- Make
sure that the IAC valve and seats are clean and free of debris as it plays an
important role in cold start drivability.
- The carbon plate should be clean and carbon free. If the EGR valve is open there will be vacuum leak so it must be closed.
Common mistakes when
diagnosing the P050D code
- Faulty
Air intake heater
- Faulty
engine coolant temperature sensor
- Circuits
/ connectors is Shorted or open
