'B' Camshaft Position Timing Over-Advanced (Bank 1)
Code P0014 indicates that the ECM commanded the Bank 1 exhaust camshaft to retard, but the camshaft remained in an advanced position. In over 85% of cases, the Variable Valve Timing (VVT) oil control solenoid is clogged with sludgy oil or seized with varnish.
Check engine oil level and color first—VVT systems operate entirely on hydraulic oil pressure. If oil is low or dirty, perform an oil change. Next, remove the exhaust VVT solenoid (held by a single 10mm bolt), clean its screens with brake cleaner, or replace the solenoid ($38).

Live Scanner & Multimeter Benchmark Values
Compare your live OBD-II PID sensor data against OEM factory operating specs for P0014.
| Monitored Parameter / Sensor PID | Healthy OEM Operating Range | Fault Threshold (Triggers P0014) |
|---|---|---|
| VVT Solenoid Resistance (Cold) | 6.5 – 12.0 Ohms | OL (Open Loop) indicates burned solenoid coil |
| Engine Oil Pressure at 2,000 RPM (Hot) | 25 – 45 PSI | <15 PSI starves VVT cam phasers of hydraulic advance |
Symptoms Associated with P0014
Drivers typically observe the following symptoms when the ECM flags P0014:

Step-by-Step Diagnostic & Repair Procedure
Follow this logical order to isolate and repair P0014 before spending money on costly parts.
Step 1: Check Oil Level and Viscosity
Pull dipstick. If oil is low or past interval, change oil with correct OEM viscosity.
Step 2: Remove Exhaust VVT Solenoid
Unbolt 10mm bolt. Twist and pull solenoid from cylinder head.
Step 3: Clean & Bench Test Solenoid
Clean mesh screens. Apply 12V battery power: internal spool valve must snap open crisply.
