Questions and answers
My mercedes gla 651 cranks but wont start, I have no faults in the scanner diagnostic, I checked injection system and it is ok with other things too. Now I want to check the camshaft position sensor but I don't know where it is located. Can you help me with it's location. Please
The camshaft position sensor on a Mercedes-Benz GLA with the OM 651 engine is located near the camshaft sprocket. It works by detecting the position of the camshaft using a Hall sensor and a sensor wheel with an orifice plate. The sensor generates signals used by the CDI control unit, and it can serve as a substitute signal if the crankshaft position sensor fails.
