What are the common causes of P0277 ?

There are four main reasons P0277 may be displayed:

• A faulty electrical connection
• The cylinder six injector has either failed or is failing
• The ECM could simply be faulty
• Electrical connections could not be working correctly

How do you troubleshoot P0277 ?

The engine system, in conjuction with the engine control module (ECM)/powertrain control module (PCM), activates the P0277 code solenoid valve to control oil pressure to the engine mechanism that is installed in the valve system to switch valve timing between Low and High.If the engine solenoid valve has an open or short circuit, a DTC is stored.
