P0021 2016 Ford F150 Code - 'A' Camshaft Position Timing Over-Advanced Bank 2
Quick Answer
The Variable Camshaft Timing (VCT) solenoid valve is an integral part of the VCT system. Common causes include Low or Dirty Engine Oil, Incorrect camshaft timing, Faulty Variable Camshaft Timing (VCT) Bank 2 Solenoid 1 (VCT21). Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0021 2016 Ford F150 Description
The PCM calculates and determines the desired camshaft position. It continually updates the VCT solenoid duty cycle until the desired position is achieved. A difference between the desired and actual camshaft position represents a position error in the PCM VCT control loop. The PCM disables the VCT and places the camshaft in a default position if a concern is detected. A related Diagnostic Trouble Code (DTC) also sets when the concern is detected.
When the VCT solenoid is energized, engine oil is allowed to flow to the VCT actuator assembly which advances or retards the camshaft timing. One half of the VCT actuator is coupled to the camshaft and the other half is connected to the timing chain. Oil chambers between the 2 halves couple the camshaft to the timing chain. When the flow of oil is shifted from one side of the chamber to the other, the differential change in oil pressure forces the camshaft to rotate in either an advance or retard position depending on the oil flow.
This DTC sets when the VCT position is over-advanced. This DTC sets when the camshaft timing exceeds a maximum calibrated value or remains in an advanced position.
What are the Possible Causes of the DTC P0021 2016 Ford F150?
- Low or Dirty Engine Oil
- Incorrect camshaft timing
- Faulty Variable Camshaft Timing (VCT) Bank 2 Solenoid 1 (VCT21)
- Faulty Camshaft Position (CMP) Bank 2 Sensor 1 (CMP21)
- Variable Camshaft Timing Bank 2 Solenoid 1 circuit is open or shorted
- Variable Camshaft Timing Bank 2 Solenoid 1 circuit poor electrical connection
- Camshaft Position Bank 2 Sensor 1 circuit is open or shorted
- Camshaft Position Bank 2 Sensor 1 circuit poor electrical connection
- Faulty Variable Camshaft Timing Phaser
How to Fix the DTC P0021 2016 Ford F150?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
