Causes

Low or contaminated engine oil (low pressure or dirty oil obstructing oil control passages)
Stuck, clogged, or faulty oil control valve (VVT solenoid/OCV)
Faulty camshaft phaser (actuator) or seized internals
Wiring problem or poor connector connection to VVT solenoid or camshaft position sensor
Faulty camshaft position sensor (bank 2) or incorrect sensor signal
Mechanical timing fault (stretched/broken timing chain, worn tensioner, jumped timing)

Symptoms

Check Engine Light (MIL) illuminated
Rough idle, hesitation or reduced performance
Poor fuel economy
Engine may run louder (valve noise) or have abnormal timing noise
Possible hard starting or limp-home mode if PCM limits performance

What to check

Read freeze frame and live data with a capable scan tool (commanded vs actual cam angle for bank 2, VVT duty, oil temp, engine RPM)
Check engine oil level and condition (visually and on dipstick); check for recent oil change and correct oil spec
Inspect connectors and wiring for VVT solenoid(s) and bank 2 camshaft position sensor for damage, corrosion or poor connections
Check for related codes (cam/crank correlation, sensors, oil pressure codes)
Check for available manufacturer TSBs or PCM software updates

Signal parameters

Camshaft position sensor (bank 2): typical square/sine waveform 0–5V; frequency increases with engine speed. Signal should be clean, without dropout or excessive noise.
VVT/Oil control valve resistance (typical range): roughly 6–35 ohms (vehicle-specific — consult spec).
VVT control: PCM uses PWM/duty cycle control (0–100%) or pulsed voltage; observe commanded duty and current draw when active.
Expected commanded vs actual cam angle: usually within a few degrees of commanded under steady conditions; large deviations or values exceeding manufacturer limits trigger P0022.

Diagnostic algorithm

Retrieve all stored codes and freeze‑frame data. Note related cam/crank codes, oil pressure codes, and which bank is bank 2 on the engine.
Visually inspect wiring and connectors for bank 2 camshaft position sensor and VVT/oil control valve. Repair any damaged connectors or wiring.
Check engine oil level and condition. If low or dirty, top up or change oil to correct spec and clear codes; retest after running the engine to proper temperature.
Using a scan tool, monitor live data: commanded cam angle, actual cam angle (bank 2), VVT duty cycle, cam sensor signal, oil temp, and RPM. Command VVT (if tool supports) and observe response.
Test the VVT solenoid: measure resistance, check for proper supply voltage and ground at connector, and confirm the PCM can command duty cycle. If the solenoid does not respond or has out‑of‑spec resistance, replace or bench test per manufacturer procedure.
Check camshaft position sensor operation: inspect waveform with oscilloscope or scan tool; replace if erratic or out of spec.
If electrical and oil flow to the phaser are correct but no cam movement occurs, inspect or remove valve cover(s) to verify phaser condition, timing chain/gear condition, and tensioner operation. Look for jumped timing, excessive wear or debris in oil passages.
If mechanical wear/damage is found (phaser, chain, guides, tensioner), perform mechanical repairs and replace damaged components as required.
After repairs, clear codes and perform road test; verify commanded vs actual camshaft angle returns to specification and code does not reappear. Check for available PCM software updates before finalizing repair.

Likely causes

Clogged or faulty oil control valve (VVT solenoid)
Low oil level or degraded oil causing poor oil control
Faulty camshaft phaser (stuck or jumped)
Wiring/connector fault to VVT solenoid or camshaft position sensor

Fault status

⚠️ Status

Intake camshaft position timing — over‑ranged (excessive) bank 2. Camshaft angle out of allowable range versus commanded position; check VVT system, oil condition, phaser and wiring.

🟡 Repair difficulty: Medium
