Why does the cam sensor not know the crankshaft position?
This is caused because the Electronic Control Module (ECM / ECU) does not receive any information from the CAM sensor, so it doesn’t know the crankshaft position. P0340 fault code is often detected which points to camshaft position (hall) sensor fault. The problem could be the wiring or camshaft sensor itself or even the ECU.
What are the symptoms of a failed camshaft sensor?
Symptoms of a failed Camshaft Sensor. If the camshaft sensor has failed you will notice some or all of the following: Check Engine Light – (CEL) / Service Engine Warning may turn on, and you will have a fault code related to the CAM sensor. Intermittent starting – This is a very common problem if the Camshaft Sensor starts to fail.
Where can I get a crankshaft position sensor code?
If your car computer has already triggered the engine light, you may retrieve the code (DTC) using a code reader. If you don’t own a code reader, most auto parts stores will retrieve (DTC)s for free. After confirming a Crankshaft – Camshaft Position Sensor related trouble code, it’s worth doing some simple tests.
How do you install a camshaft position sensor?
Unplug the electrical connector from the camshaft position sensor. Remove the bolt using E-8 Female Torx socket. Pull out the old camshaft position sensor. Install the new camshaft sensor. Ensure that the old o-ring is removed and a new one is installed.
What are the codes for the crankshaft position sensor?
First code was Camshaft position sensor – Replaced sensor Problem returned 1 week later Second code was Crankshaft sensor – Replaced sensor Problem returned 2 weeks later Third visit to mechanic computer now has (P0016, P0335b, P0339) 2 of these codes have come back and with sensors replaced feel it…
What are the symptoms of a failed crankshaft sensor?
Other symptoms of a failed crankshaft position sensor are poor acceleration, engine vibrations, poor throttle response, bad fuel economy, hesitation, engine stalls. The engine starts if you let it cool down. If you are stuck on a parking lot and the car will not start, let the car cool down at least 30 minutes and then try again.
How to change the crankshaft position on a Mercedes Benz?
Unplug the electrical connector from the CPS sensor. Squeeze the connector and pull it away from the CPS sensor. This opens in a new window. Remove bolt. Remove the crankshaft position sensor. You will have either an E8 or E10 bolt that holds the CPS sensor in place.
How do you replace a CPS sensor on an engine?
Back of engine, near the firewall. Unplug the electrical connector from the CPS sensor. Squeeze the connector and pull it away from the CPS sensor. Remove bolt. Remove the crankshaft position sensor. You will have either an E8 or E10 bolt that holds the CPS sensor in place. Install new sensor.
How do you replace the camshaft sensor on a Mercedes?
Visit the link below to check current prices. Follow these steps to replace the camshaft position sensor on your Mercedes-Benz E, C, S, CLK, ML Class and other models. Open the hood and locate the camshaft position / hall sensor. Unplug the electrical connector from the camshaft position sensor. Remove the bolt using E-8 Female Torx socket.
Is the Check Engine light still on after replacing the camshaft sensor?
Replaced camshaft position sensor but my check engine light is still on. If you replaced the camshaft position sensor and your check engine light is still on, you may need to check if there are any other fault codes. To this you will need an OBD2 scanner.
How much does it cost to replace the crankshaft position sensor?
Crankshaft Position Sensor Replacement Cost? While the prices vary based on your location the average cost of replacing the crankshaft position sensor at an auto mechanic or the Mercedes-Benz dealership vary between $250 and $400. The crankshaft position sensor cost between $100 and $150 at the dealership, that’s for the parts only.

How does the multimeter work when the engine is cranking?
Your Multimeter has to be in Volts AC mode to see this Signal. When your helper cranks the engine, the Multimeter will display about 1 Volt AC. Finally, this AC Voltage will move between .3 Volts AC to 1 Volt AC; the whole time the engine is cranking, this is normal.
What does the switching signal on a crankshaft mean?
Well, because the term ‘Switching Signal’ is just a descriptive name for the turning on and off of the primary current passing thru’ the Ignition Coil. In conclusion, this turning on and off only happens after the Ignition Module (or Fuel Injection Computer) receives the Crankshaft Position Sensor Signal.
What does fault code p0340 mean on camshaft sensor?
P0340 fault code is often detected which points to camshaft position (hall) sensor fault. The problem could be the wiring or camshaft sensor itself or even the ECU. You will be surprised how inexpensive a CAMshaft position sensor is.
How is the cam and crank signal correlated?
By utilizing the crankshaft signal in conjunction with the camshaft signal we can non-intrusively evaluate the correlation between these critical components, while also confirming the exact style of camshaft pick-up utilized by the manufacturer. The example waveform above has a Hall Effect Crankshaft sensor to Channel B (Red waveform) of PicoScope.
How to check the camshaft and crankshaft position?
Start the scope to see live data. Start the engine and run at idle. With your waveforms on screen stop the scope. Turn off the engine. Use the Waveform Buffer, Zoom and Measurements tools to examine your waveform. A digital CKP sensor signal ( Channel A) switching from just above 0 V to just below 5 V.
How to determine timing error in Cam and crank?
Then you can download the relevant waveform and carry out the identical measurement technique described above in order to determine a potential valve timing error attributed to timing chain or belt wear.
Where can I find the crankshaft position sensor?
No variation in the waveform pattern positions with respect to each other (they should not shift with time), given fixed engine operating conditions. Go to the drop-down menu bar at the lower left corner of the Waveform Library window and select Crankshaft sensor (Hall effect) or Camshaft sensor (Hall effect).
