Why Does P06dd Error Code Chevy Silverado Appear?

You see, your car’s engine is made up of numerous sensors, parts, and wires. When any of these fail, the engine notifies the PCM or the powertrain control module. If PCM detects a system error, it generates a code.

P06dd code is generated when the PCM detects an alert from the engine fuel pressure sensor. It indicates that the pressure has become too low, causing the dual-stage fuel compressor to fail.

The PCM will then try to decrease any wear and tear by disabling the Oil Filter Drive and setting a code. The condition is commonly induced by a short tensioner spring located in the timing chain guide. It is unable to direct the tilted end completely and creates problems with the oil filter or pump.

There  are a few other reasons why the error code might be flashing in your scanner:

  • The first possible reason is the low oil level
  • Error in the ECM
  • Inaccurate or incompatible Oil Filter of the Engine
  • Faulty electric connection

Symptoms And Indications

The common indication is that the oil light on your dashboard will flicker constantly. If you have an engine or OBD2 scanner, this code will appear on your monitor. Other symptoms may be

  • Extreme noise or vibration from your car’s engine
  • Frequent power cuts.
  • Tampered ideal condition
  • Lack of ideal oil pressure
