How do you fix code P0077?
What repairs can fix the P0077 code?
- Repairing open or short in the intake valve control solenoid circuit.
- Replacing or repairing connectors and wiring.
- Replacing the solenoid control valve.
What does an intake valve solenoid do?
Hear this out loudPauseThe 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 a high rate discharge test?
Hear this out loudPauseThe High Rate Discharge Tester are useful for assessing the performance of batteries used in automotive, traction, and other transient duty applications.
What is the diagnostic code for intake valve solenoid?
P0026 is a diagnostic trouble code (DTC) for “Intake Valve Control Solenoid Circuit Range/Performance (Bank 1)”.
Is the intake valve solenoid in bank 1 open?
The ECM activates the intake valve solenoid for bank 1, but the valves do not change to the high lift position. The intake valve solenoid has an open or short circuit. The wiring or connections to the intake valve solenoid is shorted or open.
What to do if your intake valve is stuck?
Follow any pinpoint test done, step by step, to isolate the failure on the system. Do not replace any parts unless directed by the pinpoint or visual test. How serious is the P0026 code? If one of the camshafts is stuck in high lift and the other in a low lift the engine may run rough and may stall when coming to a stop.
What happens when intake valve fails in low position?
The engine can experience a lack of power if the valve lift fails in the low position. The engine may run rough or stall if one of the two intake camshafts are stuck in a high valve lift position. The engine will run very erratically depending on the intake valves failed position. The Check Engine Light will be illuminated indicating a problem.
What is the function of solinoid valve?
“A solenoid valve is an electromechanical actuated valve to control the flow of liquids and gases.” Solenoid valves are used to close, dose, distribute or mix the flow of gas or liquid in a pipe. The specific purpose of a solenoid valve is expressed by its circuit function.
What is an exhaust valve control solenoid?
The exhaust valve control solenoid is part of the variable valve timing system. The variable valve timing is an important part of modern engines. It allows better acceleration and improves fuel economy.
What is an intake manifold actuator?
The variable intake manifold actuator (VIMA) controls the positions of the internal flaps and valves on the intake manifold runners to alter the amount and speed of air induction.
Does manual valve actuator work?
A valve actuator is the mechanism for opening and closing a valve. Manually operated valves require someone in attendance to adjust them using a direct or geared mechanism attached to the valve stem. Power-operated actuators, using gas pressure, hydraulic pressure or electricity, allow a valve to be adjusted remotely, or allow rapid operation of large valves. Power-operated valve actuators may be the final elements of an automatic control loop which automatically regulates some flow, level or ot
