This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer thinks the engine's parts aren't lined up correctly. It's like when the hands of a clock aren't showing the right time.
The engine control module (ECM) detects a misalignment between the crankshaft and camshaft positions on Bank 2.
The P0018 code is triggered when the ECM detects a misalignment between the crankshaft and camshaft positions. This can be due to a timing chain or belt issue, or a problem with the sensors that monitor these positions. Bank 2 refers to the side of the engine opposite Bank 1, which is usually the side without cylinder 1.

Engine Performance
• Do not ignore the Check Engine Light
• Have the vehicle inspected by a professional mechanic
• Avoid driving the vehicle if it shows severe symptoms
Check with the vehicle manufacturer for warranty coverage on timing components.
This code has been reported in vehicles with high mileage or poor maintenance history.
High – Immediate attention is required to prevent engine damage.
Driving with this code active can lead to engine damage and may not comply with emissions regulations.
• Engine at operating temperature
• Vehicle in park or neutral
The camshaft and crankshaft position sensors are typically located on the engine block or timing cover.
Q: Can I drive with a P0018 code?
A: It's not recommended as it can cause further engine damage.
Q: How serious is the P0018 code?
A: It's serious and should be addressed immediately to avoid engine damage.
