What is a VCT solenoid on f150?

Variable Camshaft Timing (VCT) is an automobile variable valve timing technology developed by Ford. It allows for more optimum engine performance, reduced emissions, and increased fuel efficiency compared to engines with fixed camshafts. (Engines that have VCT on both camshafts are now designated as Ti-VCT.)

Also, how do I know if my VCT solenoid is bad?

Here are a few symptoms of a worn out or broken VVT solenoid.

  1. Check Engine Light comes on. Since today's modern cars are controlled by an Engine Control Unit (ECU), virtually all individual components are monitored by the ECU.
  2. Engine oil is dirty.
  3. Rough engine idle.
  4. Decrease in fuel economy.

Furthermore, can a VCT solenoid be cleaned? The VCT solenoid housing itself has a micro-screen filter. You will need to remove the VCT solenoid and visually inspect for its condition (varnished, sludge, other debris). If it appears dirty, it is best to clean it by soaking it in solvent. If this doesn't work, you'll need to buy another one.

Keeping this in consideration, how does a VCT solenoid work?

The VCT solenoid is essentially an electronically controlled spool valve. The PCM controls this spool valve by pulse width modulation, or abbreviated as PWM (see Electrical Dictionary.) Depending on the position of the spool valve, it allows oil pressure to enter the phaser to advance or retard camshaft timing.

What causes a VVT solenoid to go bad?

The most common cause of failure for both the VVT switch and the VVT solenoid is a lack of basic maintenance. If your oil is dirty, sludge can clog the screen on the solenoid, causing a failure. If the engine oil level is low, you will also experience problems with VVT operation.
