Continuously adjust the intake camshaft (P016) of the right bank in the deceleration direction. Mercedes M272 engine.

This fault code causes many problems and needs to be repaired in a repair shop. Mainly from the aspects of intake cam sensor and timing regulator, it is carefully investigated.

M272 engine, you can try to change the camshaft solenoid valve first. M272 engines generally have this problem, which leads to the failure of camshaft adjuster adjustment and engine failure light. If it doesn't work, it's the camshaft adjuster.

Camshaft solenoid valves in intake and exhaust are the same, so they can be switched. If there is any fault in the trial run, see if there is any transfer. In other words, the price of a solenoid valve accessory in a 4S shop is several hundred yuan.

Extended data:

The common transmission modes between camshaft and crankshaft are gear transmission, chain transmission and toothed belt transmission. The transmission between the lower camshaft and the middle camshaft and the crankshaft mostly adopts cylindrical timing gear transmission. Generally speaking, the transmission from crankshaft to camshaft only needs a pair of gears. If the diameter of the transmission gear is too large, add 1 intermediate idler. In order to mesh smoothly and reduce working noise, most timing gears adopt helical gears.

The camshaft bears periodic impact load. The contact stress between cam and tappet is large, the relative sliding speed is also high, and the working surface of cam is seriously worn. In view of this situation, the working surface of camshaft journal and cam should have high dimensional accuracy, small surface roughness and sufficient stiffness, as well as high wear resistance and good lubricity.
