Question

What is code P0018​?

The P0018 code is defined as "Crankshaft Position - Camshaft Position Correlation (Bank 2 Sensor A)," meaning that the powertrain control module (PCM) found out that the Bank 2 camshaft is not in the correct position when correlated to the crankshaft. ‘Bank 2’ refers to the engine’s side that does not have cylinder one. However, ‘Sensor A’ represents the intake camshaft sensor.

What are the symptoms of the P0018 code?

These are some signs that you can observe when the PCM logs this code.

• The check engine light illuminates
• A rattling sound from the engine
• Engine performance decreases
• The engine may not start
• Hard start
• The engine stalls, runs rough, erratically, or hesitates

What can cause a P0018 code?

These are some reasons why the code shows up in your car.

• The engine oil level becomes low
• Engine timing is incorrect
• Defective timing chain tensioner or guides
• A failed camshaft variable timing solenoid
• A faulty variable valve timing actuator
• The timing chain becomes damaged
• Defective or shifted crankshaft reluctor wheel
• The engine oil used doesn’t match the manufacturer’s specifications
• The oil control valve is stuck open or closed automatically
• Issues with the variable valve timing (VVT)
• A defective PCM
• Problems with the camshaft or crankshaft sensor

How to fix the P0018 code​

These are some repairs you can do to fix this code.

• Repair or replace the wiring on Bank 2’s camshaft sensor.
• Replace the camshaft oil control valve or the Bank 2 camshaft’s camshaft sensor.
• Repair or replace the connection or wiring to the camshaft OCV.

How much does it cost to fix the P0018 code?

The cost to fix the P0018 code can range between $200 and $400 for replacing sensors, or can go as high as $1,500 to $3,500 if the tensioners, timing chain, or cam phasers require replacement. The actual fix cost can differ based on the car you own, the original cause, and the location of the repair.

Can I drive with a P0018 code?

No, we don’t recommend that you drive with this code. Prolonged driving with this error code can lead to issues like stalling, hard starting, or hesitation. There may even be issues with the tensioners, timing chains, or guides, causing internal engine damage if the valves collide with the pistons. So, when diagnosing the code, quickly take your car to a qualified technician for repair.
