P0022
UniversalThe P0022 code indicates that the Powertrain Control Module (PCM) has detected that the actual position of the intake camshaft on engine Bank 2 is more retarded than commanded, or outside its specified operating range, for a predetermined amount of time.
Medium SeverityP0022 indicates that the Intake Camshaft timing on engine Bank 2 is excessively retarded. This means the engine's variable valve timing (VVT) system is not properly advancing or retarding the camshaft as intended, leading to reduced engine performance and potentially poorer fuel economy.
⚠️ Before You Begin (Safety First)
Always ensure the vehicle is on a level surface and the parking brake is engaged before working. Disconnect the negative battery terminal before performing any electrical work. Allow the engine to cool completely before touching engine components to prevent burns. Wear appropriate personal protective equipment, including gloves and eye protection.
Common Symptoms
- Rough idle or stalling
- Reduced engine performance or power
- Decreased fuel economy
- Check Engine Light illuminated
- Difficulty starting (less common)
Common Causes
- Faulty Variable Valve Timing (VVT) solenoid (also known as oil control valve)
- Low or dirty engine oil (critical for VVT operation)
- Faulty camshaft position sensor
- Damaged or worn camshaft phaser/actuator
- Wiring issues or poor electrical connections to the VVT solenoid or camshaft position sensor
- Timing chain or belt issues (stretched or jumped timing)

Diagnostic Steps
- Check engine oil level and condition. Ensure it is clean and at the proper level.
- Visually inspect the wiring and connectors to the VVT solenoid and camshaft position sensor on Bank 2 for damage or corrosion.
- Locate and test the VVT solenoid for Bank 2. This often involves applying battery voltage to see if it clicks or removing and inspecting it for clogs.
- If accessible, clean the VVT solenoid screen and solenoid itself with brake cleaner.
- Clear the code and test drive the vehicle to see if the code returns.
- If the code returns, consider replacing the VVT solenoid for Bank 2.
👨🔧 When to Call a Professional
If after checking and replacing the Variable Valve Timing (VVT) solenoid and verifying wiring, the code persists, it's highly recommended to consult a professional mechanic. The issue may involve internal engine components such as the camshaft phaser or require specialized diagnostic equipment to determine the root cause, which can prevent further engine damage.
Commonly Asked Questions
What does 'Bank 2' mean for P0022?
'Bank 2' refers to the side of the engine that does NOT contain cylinder #1. In a V-type engine, this will be one side of the 'V'.
Can low or dirty oil cause P0022?
Yes, absolutely. The Variable Valve Timing (VVT) system relies heavily on clean engine oil at the correct pressure to function properly. Low or dirty oil is a very common cause of P0022.
Is it safe to drive with P0022?
While you might be able to drive, it's not recommended for extended periods. The engine's performance will be compromised, fuel economy will suffer, and continued driving could lead to further engine damage or wear.
How do I identify the VVT solenoid for Bank 2?
The VVT solenoids are typically located on the valve covers or front of the cylinder heads. Consult your vehicle's repair manual or an online diagram for the exact location of the intake VVT solenoid for Bank 2.
What's the difference between a VVT solenoid and a camshaft phaser?
The VVT solenoid (or oil control valve) is an electrical component that controls oil flow. The camshaft phaser (or actuator) is a mechanical component mounted on the camshaft that uses oil pressure, controlled by the solenoid, to physically adjust the camshaft's timing.
