P0022
Fix within a few daysThe engine's computer detects that the intake camshaft on Bank 2 is stuck in a retarded (late) position, meaning it's not adjusting its timing as commanded.
Code P0022 means your Bank 2 intake camshaft timing is stuck retarded. Common causes: Low/dirty oil (30%), faulty VVT solenoid (40%), bad cam phaser (15%). Drivability: Limit driving, fix within a few days. Repair cost: $50-$200 DIY, $150-$500 professional.

Common Causes of P0022
Parts most likely causing this code, ranked by probability
The Variable Valve Timing (VVT) system relies on clean engine oil at the correct pressure to operate the camshaft phasers.
30% of P0022 cases are fixed by addressing oil level or quality
This solenoid controls the oil flow to the camshaft phaser, and if it's faulty or clogged, the cam timing cannot be adjusted correctly.
40% of P0022 cases are fixed by replacing this part
The sensor provides feedback to the engine computer about the camshaft's actual position; a faulty sensor can send incorrect data.
10% of P0022 cases are fixed by replacing this part
This mechanical component directly adjusts the camshaft timing; internal failure or sludge buildup can prevent it from moving freely.
15% of P0022 cases are fixed by replacing this part
Damaged wires or corroded connectors to the VVT solenoid or camshaft position sensor can disrupt signals.
5% of P0022 cases are fixed by repairing wiring
Check These First (Before Buying Parts)
- Check your engine oil level and condition. Low or dirty oil is a common cause for VVT system malfunctions. Top off or change oil if needed.
- Visually inspect the electrical connector and wiring going to the Bank 2 intake VVT solenoid and camshaft position sensor for any signs of damage, fraying, or corrosion.
How to Diagnose P0022
- 1Check engine oil level and condition. Top off or change oil if necessary.
- 2Inspect the wiring and electrical connector for the Bank 2 intake VVT solenoid and camshaft position sensor for damage or corrosion.
- 3Test the resistance of the Bank 2 intake VVT solenoid. Compare to factory specifications.
- 4Remove and visually inspect the Bank 2 intake VVT solenoid for clogs or debris. Clean if possible, then retest.
- 5If the solenoid tests good, test the camshaft position sensor for Bank 2 intake.
- 6If all electrical components test good, consider a faulty camshaft phaser or timing chain issue, which requires more in-depth diagnosis.
P0022 on Popular Vehicles
Nissan
2002-2024Common on VQ series engines (3.5L, 3.7L). Often related to VVT solenoid failure or sludge buildup from infrequent oil changes. Bank 2 is the driver's side on most V6/V8 Nissan vehicles.
70% fixed by replacing VVT solenoid or addressing oil issues
Ford F-150
2004-2014On 3-valve Triton engines (4.6L, 5.4L), P0022 can indicate issues with the cam phasers, often exacerbated by low oil pressure or worn timing components. This is a more involved repair.
60% fixed by replacing cam phasers and related timing components
Subaru
2005-2024Common on EJ series engines with AVCS (Active Valve Control System). Often due to a faulty AVCS oil control valve (VVT solenoid) or restricted oil passages. Bank 2 is the passenger side on most Subaru boxer engines.

Frequently Asked Questions
What does P0022 mean?
P0022 indicates that your engine's computer has detected an issue with the Variable Valve Timing (VVT) system on Bank 2, specifically that the intake camshaft is stuck in a 'retarded' or late position.
Can I drive with P0022?
Yes, for short trips only. You can drive your vehicle to a repair shop, but extended driving can cause reduced engine performance, poor fuel economy, and potentially lead to more serious engine damage if ignored.
Will P0022 clear itself?
No, P0022 will not clear itself. The underlying mechanical or electrical issue causing the camshaft timing problem needs to be diagnosed and repaired. Once fixed, the code can be cleared with a scan tool.
How do I fix P0022 myself?
Start by checking your engine oil level and condition. If the oil is good, you can try replacing the Bank 2 intake VVT solenoid. This is often an accessible part. If that doesn't work, testing the camshaft position sensor is the next step.
How much does it cost to fix P0022?
DIY costs for P0022 typically range from $50-$200 for a VVT solenoid or camshaft position sensor. Professional repair costs usually fall between $150-$500, depending on the part and labor rates. If it's a timing chain or phaser, costs can be $1000+.
P0022 keeps coming back - why?
If P0022 keeps returning, it often means the initial repair didn't address the root cause. This could be due to persistent low oil pressure, a clogged oil passage, a faulty camshaft phaser, or even a stretched timing chain that wasn't initially diagnosed.
Will P0022 fail emissions/smog test?
Yes, P0022 will cause your vehicle to fail an emissions or smog test. The Check Engine Light being on automatically results in a failure, and the VVT system directly impacts engine emissions.
What's the difference between P0022 and P0012?
P0022 indicates an 'over-retarded' camshaft timing condition on Bank 2 (the side of the engine without cylinder 1). P0012 indicates the exact same 'over-retarded' condition, but on Bank 1 (the side of the engine with cylinder 1).
P0022 on Nissan VQ engine (3.5L/3.7L)
On Nissan VQ engines, P0022 is frequently caused by a faulty VVT (Variable Timing Control) solenoid on Bank 2. These engines are sensitive to oil quality and maintenance, which can contribute to solenoid failure or sludge buildup in the VVT system. Less commonly, it can point to a failing cam phaser or timing chain issues.
Questions to Ask Your Mechanic
Did you check the engine oil pressure and condition before diagnosing the VVT system?
Good answer: Yes, we confirmed the oil level is correct and the oil is clean. We also checked the oil pressure at idle and it's within specifications.
What were the readings for the Bank 2 intake camshaft position sensor and VVT solenoid during your diagnostic tests?
Good answer: The cam sensor showed a consistent signal, but the VVT solenoid's commanded position didn't match its actual position, indicating it's either stuck or not receiving proper oil flow.

Intermediate - Replacing a VVT solenoid or camshaft position sensor is often a manageable DIY task for someone with basic mechanical skills and tools. Diagnosing deeper issues like cam phasers or timing chains requires more advanced knowledge and tools, making professional help recommended.
Cost of Waiting
Ignoring P0022 can lead to significant engine damage. Continued incorrect camshaft timing causes poor combustion, which can overheat and destroy your catalytic converter ($800-$2,500 repair). It also increases wear on internal engine components and can lead to complete engine failure over time. A $100 solenoid fix now prevents a $2,000+ bill later.
While You're In There...
The VVT system relies heavily on clean oil. If you're diagnosing or replacing VVT components, a fresh oil change is a smart move to ensure proper system function and prevent future issues.
These small seals are often included with a new solenoid, but if not, replace them to prevent oil leaks when reinstalling the solenoid.
Tools You'll Need
- OBD-II scan tool
- Basic hand tools (sockets, wrenches)
- Multimeter (for electrical testing)
- Engine oil pressure gauge (optional, but helpful)
P0022 is a common engine code related to your variable valve timing system. While it can impact performance, most repairs are straightforward, often involving a VVT solenoid, and your engine will run smoothly afterward.

Your Next Steps
Step 1: Check your engine oil. Ensure it's at the correct level and is clean. If it's low or dirty, top it off or perform an oil change. Clear the code and see if it returns.
Step 2: If the code persists, locate and inspect the Bank 2 intake VVT solenoid and its electrical connector. Test the solenoid's resistance with a multimeter. If it's out of spec or clogged, replace it.
Step 3: If the solenoid is good, test the Bank 2 intake camshaft position sensor. If it's faulty, replace it. If both components are good, you're likely looking at a more complex issue like a faulty cam phaser or timing chain problem, which often requires professional diagnosis.
