Mercedes-Benz Camshaft Adjuster Magnets Replacement Guide

In this guide, you will find step-by-step instructions on how to replace Mercedes-Benz Camshaft Adjuster Magnets also known as camshaft timing control solenoid.

In this guide, you will find instructions on how to replace your Mercedes-Benz Camshaft Adjuster Magnets, sometimes called sensors or solenoids. 

The steps outlined below show how to replace driver's side sensors which are harder due to limited space. On the other hand, the passenger side sensors are much easier and straightforward to replace. 

Symptoms

A failing camshaft magnet sensor will almost always turn on the check engine light and may produce code P0015 (Camshaft Position B- Timing Over-Retarded (Bank n)).

The M272 and M273 engines have four Camshaft Adjuster Magnets. In addition, the check engine light may come on with codes such as P0011, P0012, P0015, and P0014.

Procedure

  1. Place the vehicle in the park.
  2. Allow the engine to cool down.
  3. Pop the hood open by pulling the hood release under the hood. 
  4. Use the suction pump to drain all power steering fluid.
  5. Remove the power steering reservoir. You will find the steps in power steering reservoir removal at this linkremove-power-steering-reservoir

     

  6. Using an e-8 t-wrench, remove all bolts from the exhaust cam magnetic sensor.remove-all-bolts-from-ex-magnet-sensor
  7. Disconnect electrical connections of the exhaust cam magnetic sensor using a flat head screwdriver to push the tabs on the connectors.remove-electrical-connector-ex-mag-cam

     

  8. Place something to catch the sensor if it drops out of your grip, then pry the exhaust cam magnetic sensor out using a flat head screwdriver.pry-exhaust-mag-sensor
    Ensure that the exhaust cam magnetic sensor sealing 0-ring is removed from the hole and be sure to include a new ring during replacement.
  9. Lubricate the new exhaust cam magnetic sensor before installation, so it will be easy to install it.lubricate-new-sensor

     

  10. Position the new exhaust cam magnetic sensor in place, make sure to install the o-ring together with it.install-new-magnetic-sensor-ex
  11. Using an e-8 socket, reinstall the retaining bolts, carefully balancing the torque on three (3)bolts.reinstall-bolts-ex-mag
  12. Reconnect the electrical connectors on the exhaust cam magnetic sensor.reconnect-ex-cam-electrical
  13. To remove the intake magnetic cam sensor, you have to remove the exhaust cam position sensor first, which has two bolts.remove-ex-cam-pos-sensor

     

  14. Move the exhaust cam position sensor out of the way.move-cam-sensor-away
  15. Using a flat head screwdriver, disconnect the intake cam position sensor connector and move it out of the way.disconnect-cam-sensor-connector
  16. Remove the intake cam position sensor by removing the e-8 bolt.remove-intake-cam-sensor

     

  17. Using an e-8 socket, remove two (2) exposed bolts from the intake cam magnetic sensor.remove-in-bolts
  18. Using a quarter-inch wrench, remove the bolt hidden behind the oil cooler. The other option is to remove the oil cooler, which takes more time. remove-hidden-bolts

     

  19. You may use a flat-head screw and a finger to remove the bolt since the headroom would max out completely, and the wrench would no longer be usable.use-flat-screw-method

     

  20. Pry the intake magnetic cam sensor out using a flat head screwdriver.remove-intake-cam-sensor
  21. Remove the intake cam sensor, don't forget to take out the old o-ring.remove-intake-magnetic-sensor
  22. Lubricate the new intake magnetic cam sensor rubber o-ring.lubricate-intake-mag-sensor

     

  23. Install the new intake magnetic cam sensor.install-new-sensor-intake
  24. You may use a long flat head screwdriver to press the magnetic sensor in place.press-wiht-screw-driver

     

  25. Install retaining bolts to accessible slots.install-retaining=bolts
  26. Tighten the accessible retaining bolts.tighten-bolt

     

  27. Install the last retaining bolt by hand first.install-last-bolt

     

  28. Fasten the last retaining bolt using a quarter-inch wrench. It will be challenging to get the first few threads started due to the limited space. 
  29. Install the exhaust cam position sensor and then tighten its bolts, make sure the o-ring is attached to the sensor. Next, make sure the old O-ring is removed. In some cases, the old o-ring gets stuck, and you end up with two o-rings, which will lead to the sensor sitting flush and oil leaks developing.  install-ex-cam-sensor
  30. Install the intake cam position sensor and install, then fasten its bolt, make sure the o-ring is attached to the sensor.install-intake-cam-sensor
  31. Reconnect all electrical connectors for cam position sensors (intake and exhaust) and magnetic cam sensors (intake and exhaust).install-all-electrical-connections

Frequently Asked Questions

How long can I drive with the check engine light on and code P0015?

  • The first symptom of a failing camshaft sensor manifests as a check engine light coming on. When the check engine light first comes on, the driver has enough time to service the car and replace all faulty parts. If you ignore this flashing light for a considerable time, it could lead to a more expensive engine problem.

What is the purpose of a Mercedes Benz Magnetic Cam Sensor or camshaft adjuster Solenoid?

  • The camshaft adjuster solenoid's (Magnetic Cam Sensor)  primary purpose is to allow more oil to enter the system, ensuring proper lubrication under a more massive load.

How would you know that your magnetic cam sensor is bad?

  • The vehicle does not drive like it used to. If your vehicle idles roughly, stalls frequently, drop in engine power, stumbles, reduced gas mileage, or accelerates slowly. These are all signs your camshaft position sensor could be failing.
  • Check Engine Light comes on, which would produce code P0015.
  • The vehicle might not start.
