What is 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).
What is code P0026 mean?
P0026 is the OBD-II generic code indicating the engine control module (ECM) has determined that the variable valve lift solenoid for the intake valves for bank 1 takes too long to engage or does not engage.
What are the symptoms of a bad VVT solenoid?
Common VVT Solenoid Failure Symptoms
- Rough Engine Idle.
- Check Engine Light.
- Misfiring engine under loads.
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 causes a p0028 code on a valve lift?
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 is the fault code on a Subaru Impreza?
In this video we discuss a common Subaru fault code associated with variable valve lift systems on the 2.5L engines. This code is common across 2006-2011 Subaru Foresters, Impreza, Outback and Legacy vehicles equipped with the 2.5L engine. P0026 and P0028 indicate a fault in the VVL circuit.
What happens to the solenoid on a Subaru Outback?
If its low of oil, the solenoid operates but the cam doesn’t change and the pressure switch feedback doesn’t change. Since the ECM only sees voltage data and not mechanical, it sets a code for the solenoid circuit assuming that the oil is at the proper level and viscosity and the signal returned to it by the pressure switch is correct.
