Diagnostic code
P0014 Code: B Camshaft Position Timing Over Advanced Bank 1
P0014 means the exhaust camshaft timing on bank 1 is advanced beyond the expected range. Oil quality, VVT solenoid control, actuator movement, wiring, and mechanical timing all affect this code.
Can I drive?
Driving should be limited if the engine idles poorly, stalls, or has timing noise. Check oil level before continuing.

Plain-English Meaning
P0014 means the exhaust camshaft timing on bank 1 is advanced beyond the expected range. Oil quality, VVT solenoid control, actuator movement, wiring, and mechanical timing all affect this code.
Common Causes
Symptoms
- Check engine light
- Rough idle
- Poor low-speed power
- Hard starting
Diagnostic Steps
- 1Verify oil level and correct viscosity
- 2Check for related timing codes
- 3Command or test the exhaust cam solenoid
- 4Inspect solenoid wiring and connector
- 5Confirm mechanical timing if data remains abnormal
Confusable And Related Codes
P0174
Compare →P0174 means bank 2 is running lean and the computer is adding fuel to compensate. It is common on V-style engines when unmetered air enters one side of the intake, fuel delivery is weak, or the mass airflow reading is inaccurate for the act
P0300
Compare →P0300 means the engine is misfiring randomly or across multiple cylinders instead of one clearly identified cylinder. Ignition, fuel, air leaks, compression problems, or timing issues can all interrupt combustion and trigger this code.
P0128
Compare →P0128 means the engine is taking too long to reach the expected operating temperature. A thermostat stuck open is common, but low coolant, sensor readings, wiring, and fan behavior should be checked before parts are replaced.
P0011
Compare →P0011 means the intake camshaft timing on bank 1 is more advanced than the engine computer expected. Variable valve timing systems depend on clean oil, correct oil pressure, working solenoids, and accurate cam/crank signals.
FAQ
What does B camshaft mean on P0014?
B usually refers to the exhaust camshaft on the affected bank.
Can an oil change fix P0014?
It can help if oil condition or level caused the VVT system to stick, but diagnosis is still needed.
Can P0014 cause misfires?
Incorrect cam timing can cause rough running that may be reported as misfire symptoms.
