What is P0027 fault code? What is the Exhaust Valve Control Slenoid Circuit Range/Performance Bank 1 malfunction description? How do I fix the P0027 fault code What are the causes of the P0027 code fault?

What is the P0027 Fault code? What does it signify?

Vehicles equipped with variable timing (VVT) will have a P0027 code triggered when the powertrain controller module (PCM), determines that the exhaust vales are slow to activate or don’t engage properly. The code description states that “Bank 1” refers to a problem in the bank containing engine’s #1 Cylinder. The exhaust valve control solenoid can be found on the exhaust manifold side the cylinder head.

Note: This code could also be associated to codes P0078 , P0079 Oder P0080 . Before the P0027 faultcode can be applied, it is necessary to eliminate any of these codes.

There are many vehicles that can be affected by fault code P0027, including but not limited to: Toyota, Volkswagen and Dodge models, as well as Toyota, Volkswagen, Ford and Dodge models.

What is the P0027 Fault Code and Why Does It Happen?

Here are some reasons why P0027 should be set.

  • – The exhaust valve control solenoid circuit can be opened or closed.
  • – The exhaust valve solenoid circuit is prone to damage or rusty wires
  • – A poor connection in ground cable to the PCM
  • – Low engine oil
  • – Engine oil with a low viscosity or dirtiness
  • – Oil passage lines blocked
  • – VVT oil control solenoid defective
  • – Defective VVT actuator
  • – Timing belt/timing chain loose or misaligned

What are the symptoms of the P0027 Fault Code?

You may experience the following symptoms if your vehicle has a P0027 Code:

  • – Illumination for the check engine light
  • – Reduced engine performance
  • – Engine hesitation during acceleration
  • – The engine is not working properly
  • Engine misfire
  • – Increased fuel use

How to Fix the P0027 Fault Code

The following repairs may be able to resolve the P0027 fault code:

  • – To find out if the fault is returning, first clear all codes. Then perform a road test.
  • Check your engine oil level. If it is low, you should replace it.
  • – Oil filter and engine oil with a low viscosity must be replaced.
  • If the solenoid for exhaust valve control is defective, it should be replaced.
  • Repair of damaged wires, connectors, or open or brief circuits to the exhaust control solenoid
  • – Replacing a damaged or worn timing chain or belt
  • – Reparing or replacing the PCM connector
