P0026 - Intake Valve Control Solenoid Circuit Range/Performance (Bank 2)

About Trouble Code P0026

When there is trouble engaging the variable valve lift solenoid for the intake valves for bank one, the engine’s computer will generate code P0025. This can occur if it does not engage at all or if it takes too long to engage.

Symptoms of Trouble Code P0026

Initial indication of the problem will be the illumination of the check engine light. A lack of power may be experienced if the valve lift fails while it is in the low position. If one of the two intake camshafts are stuck in a high valve lift position the engine may stall or give the driver a rough ride. Depending on the intake valve’s position the engine may run very erratically.

Causes of Trouble Code P0026

An open or short circuit in the intake valve solenoid can cause trouble code P0025. In addition, if there are shorted or open wiring or connections to the intake valve you may also see this trouble code. The engine’s computer may tell us this is the problem if the intake valve solenoid for bank one does not change to the high lift position when instructed to do so. You may also have a defective or loose connection to the engine’s computer.

How to Fix Trouble Code P0026

Start with clearing the trouble code and driving the vehicle to validate the code is real. You will then want to test the solenoid installed to ensure the valves are working correctly. If they are not you will need to replace the intake lift solenoid. Check for corrosion and damage to the wiring and connections to the intake life solenoid. Finding none of these things to be helpful may mean taking a deeper look into the engine’s computer for malfunction.
