This monitor does not judge the end position of the exhaust camshaft on bank 2 but how fast it follows a change of the commanded angle. The code is set when the actual angle lags behind the target for too long during several adjustments. The adjustment speed depends directly on oil flow, so worn or wrong oil and a partly clogged screen are the usual causes. Drivability is often hardly affected; the fault is an early warning before the camshaft misses its target position altogether. Bank 2 exists only on V and boxer engines; it is the cylinder bank without cylinder 1.
Likely causes
Oil too thick or too thin, sludged, or oil level low
Screen at the oil control valve partly clogged
Oil control valve sluggish
Cam phaser leaking internally or worn
Generally weak oil pressure, e.g. worn oil pump or bearings
Symptoms
- Check engine light on
- Slight hesitation when accelerating
- Often no noticeable symptoms
