This is obviously the real cause of the failure to be found correctly!

This fault code, first look at the camshaft regulating valve, then look at the balance wheel and chain, most of them are caused by the balance wheel, shake the crankshaft to 305 °, and look at the Hall sensor where the signal disk is accurate! If you don't allow, call it out and change the balance wheel.

Fault code: P0016

Chinese meaning: crankshaft position camshaft position correlation (bank 1, sensor a).

Detailed meaning: The function of the crankshaft is to turn the up and down motion of the piston into a rotary motion. The role of the camshaft is to control the opening and closing of the valves.

The electronic control unit (ECU) continuously monitors the timing position of the variable camshaft and checks the relative position between the camshaft and the crankshaft. If the relative position is misaligned by more than 1 tooth, the fault code will appear. Causes of failure include failure of the camshaft position sensor itself or its circuit, failure of the crankshaft position sensor itself or its circuit, failure of the engine speed sensor, contamination of the oil, jamming of the variable camshaft solenoid valve, etc.

Hello, check whether the variable air intake system and related circuits and solenoid valve oil passages are unobstructed.

Summary. Hello. Friend.

Mercedes-Benz P017222 fault code: the mixture is too thick.

Here's how to fix it:

The opening of the choke should be checked first and the oil needle adjusted. If there is no obvious effect, remove the air filter screen and see if the machine is working better. When the above methods are ineffective, finally disassemble the carburetor to check the oil level and measuring hole of the float chamber.

Here's how:

1. The first way to deal with over-concentrated mixture is to check the pipeline from the oil tank to the carburetor joint, if there is oil leakage, blockage, etc., it should be dredged or replaced;

2. The second is to check the gasoline pump, if the gasoline pump is faulty, the gasoline pump should be replaced;

3. Check the opening of the carburetor inlet needle valve or the float height, if there is any undesirable phenomenon, it should be adjusted;

4. If the main measuring hole or the main oil supply channel in the carburetor is blocked, it should be cleaned and dredged;

5. If the liner is damaged or leaking, it should be replaced.

Hope it helps.
