P0336 MERCEDES-BENZ Possible Causes
- Faulty Crankshaft Position Sensor
- Crankshaft Position Sensor harness is open or shorted
- Crankshaft Position Sensor circuit poor electrical connection
- Signal plate may be damage
- Starter motor may be faulty
- Starting system circuit
- Dead or weak battery
How do I fix code P0336 MERCEDES-BENZ?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Tech Notes
- Mercedes Benz Code = 0117 Number of teeth on sensor rotor too high or too low or wiring (P0336)
- Mercedes Benz Code = 0119 No tooth space on sensor rotor detected or wiring error (P0336)
- Mercedes Benz Code = 0120 Tooth space on the sensor rotor temporarily not detected or wiring error (P0336)
- Sometimes and in some models, low battery voltage or a weak starter can trigger a Crankshaft Position Sensor code. Before replacing any parts, recharge or replaced the battery.
Cost of diagnosing the P0336 MERCEDES-BENZ code
The cost of diagnosing the P0336 MERCEDES-BENZ code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
When is the code detected
The Crankshaft Position Sensor (POS) signal is not detected by the Electronic Control Module (ECM) during the first few seconds of engine cranking
Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power
- Engine Stall
P0336 MERCEDES-BENZ Description
This fault code is stored in the Engine Control Module (ECM) when the output from the crankshaft position sensor is not as expected or missing. The ECM uses information from the camshaft position sensor to validate the signal from the crankshaft position sensor. The phonic wheel for the crankshaft position should also be inspected as incorrect fitment or damage can affect the signal. Incorrect valve timing can also cause this fault. Mechanical defects such as a faulty dual mass flywheel or worn crankshaft thrust bearing washers can cause signal anomalies and result in this fault code being stored.
