P0014"B" Camshaft Position - Timing Over-Advanced or System Performance (Bank 1)
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- The engine control module compares the commanded position of the exhaust camshaft on bank 1 with the actual position it calculates from the camshaft and crankshaft sensors. This code is set when the camshaft sits further advanced than commanded for longer than a calibrated time, or, depending on the manufacturer, when the target is missed in either direction ("system performance"). Typical cause is a phaser that does not return to its rest position, for example because the oil control valve sticks open or its screen is clogged. Bank 1 is the cylinder bank that contains cylinder 1.
