Intake Valve Control Solenoid Circuit Bank 2
P0081 — Intake Valve Control Solenoid Circuit Bank 2. It is a medium-severity fault: you can usually keep driving for short distances. The most common cause is circuit problems – wire harness and connector damage are the main causes of this vvt failure. poor repair practices and rodent damage are common causes of this type of damage.
"Caution: ignore it long enough and it gets expensive opinions about your wallet."
P0081 is a powertrain diagnostic trouble code. It identifies a fault related to For the internal combustion engine to function, the valve system opens and closes the cylinder at different points in the cycle. On the intake stroke, for example, the intake valves should be open, allowing air and fuel to enter the cylinder. On the compression and power strokes, both intake and exhaust valves are closed. Finally, on the exhaust stroke, the exhaust valves open to allow the exhaust to escape through the exhaust manifold. Granted, this is an oversimplification, because we have to. The powertrain control module monitors this circuit or component continuously and sets P0081 when the signal or value is outside the expected range, implausible or missing. This can affect engine performance, fuel economy or emissions and usually turns on the check-engine light. The base function may still work, but performance can be affected, so the fault should be diagnosed. Diagnosis generally means inspecting the related wiring, connectors and power/ground references, then verifying the component against specification with a scan tool.
