What causes P0028 code?
What causes P0028 code?
P0028 is related to the OBD-II codes P0026, P0027, and P0029. n other vehicles, this code sets if the PCM detects that there there is a difference between the actual camshaft position and the desired camshaft position.
Where is intake valve control solenoid?
In most vehicles, the intake valve control solenoid is usually found on the intake manifold side of the cylinder head.
What side is Bank 1 on a Subaru?
The Subaru Impreza bank 1 sensor 1 is located on the passenger side of the exhaust before the catalytic converter. This is Your oxygen sensor. Some symptoms that You might be experiencing are higher than normal fuel consumption and excessive smoke coming from Your exhaust.
What is an intake control solenoid?
Your engine’s primary air intake valve connects to the IAC or Idle Air Control Solenoid Valve. That valve is what makes necessary adjustments to airflow to the engine and maintains a smooth idle. The IAC lets in air to keep the engine from choking when the throttle plate is closed by taking your foot off the gas.
What is an intake valve control solenoid?
The Intake Valve Control Solenoid uses oil pressure and an electrical solenoid to control the position of the exhaust valve. Newer vehicles are equipped with variable valve timing (VVT).
Where is the p0028 code on a Subaru Outback?
Fruit Flies Like a Banana! Oil level and leaks around the variable valve lift solenoids or pressure sensor switches have been seen before as causes of the P0028 code, as has been noted above. The code is for bank 2. The related solenoid and switch are at the front of the left side head and easily checked for oil leaks.
What does the p0028 OBD-II generic code mean?
What the P0028 code means P0028 is the OBD-II generic code indicating the engine control module (ECM) has determined that the variable valve lift for the intake valves for bank 2 will not engage. What causes the P0028 code? The ECM activates the intake valve solenoid for bank 2, but the valve lift mechanism did not change.
What does p0028 mean on an intake valve?
P0028 is a diagnostic trouble code (DTC) for “Intake Valve Control Solenoid Circuit Range/Performance (Bank 2)”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What happens when oil pressure is low on a Subaru Outback?
If its not low, then there may be an issue with the control solenoid, pressure switch or oil circulation for cam lift to take place. The VVL solenoid controls oil flow to change the camshaft lift. If its low of oil, the solenoid operates but the cam doesn’t change and the pressure switch feedback doesn’t change.
