Information Regarding the Engine Crankshaft Position Sensor for the 2012-2016 Mercedes-Benz C43 AMG
This article addresses a common vehicle model and year range discrepancy to ensure you find the correct parts.
- The 2012-2016 Mercedes-Benz C43 AMG does not exist; the performance model for this period was the C 63 AMG.
- The modern C43 AMG was introduced for the 2017 model year.
- Always verify your exact model and year before purchasing parts, preferably using your VIN.
- Parts for a C 63 AMG and a C43 AMG are not interchangeable due to different engines and chassis.
Vehicle Model & Year Inaccuracy
The vehicle specified, a 2012-2016 Mercedes-Benz C43 AMG, was not manufactured for the North American market. This guide clarifies the available AMG models for this period and the correct model years for the C43 AMG to help you find the right information.
Correct Models for the 2012-2016 Period
During the 2012-2015 model years, the primary performance AMG model for the C-Class (W204 chassis) was the Mercedes-Benz C 63 AMG. This model is known for its naturally aspirated 6.2L V8 engine. If you own an AMG C-Class from this era, it is likely a C 63.
Correct Years for the C43 AMG
The modern Mercedes-AMG C43 (W205 chassis), featuring a twin-turbo V6 engine, was introduced later. It began as the C 450 AMG for the 2016 model year and was officially named the C43 AMG starting with the 2017 model year. Therefore, any search for C43 AMG parts should begin with the 2017 model year.
General Symptoms of Crankshaft Sensor Failure in Mercedes-Benz Vehicles
While we cannot provide information for a non-existent model, symptoms of a failing crankshaft position sensor are consistent across most Mercedes-Benz vehicles, including the C 63 AMG and the 2017+ C43 AMG. Look out for these signs:
- Engine Not Starting: The engine cranks but refuses to start because the ECU isn't receiving a signal to create spark.
- Intermittent Stalling: The car may stall unexpectedly while driving, which can be a significant safety hazard.
- Rough Idle and Engine Misfires: The engine may run poorly, vibrate excessively, or misfire.
- Check Engine Light: A failing sensor will almost always trigger a Check Engine Light.
- Poor Acceleration: The car may feel sluggish and unresponsive when you press the gas pedal.
Pro Tip: Before ordering a part, always verify your vehicle's model and production year. This can be found on the sticker inside the driver's door jamb or on your vehicle's registration documents. Providing a Vehicle Identification Number (VIN) to a parts supplier is the most reliable way to ensure you receive the correct component.
Frequently Asked Questions
Why can't I find parts for a 2014 C43 AMG?
The C43 AMG was not produced in 2014. The AMG model for that year was the C 63 AMG. The modern C43 AMG model line began in 2017.
Are the crankshaft sensors for a C 63 AMG and a C43 AMG the same?
No. The 2012-2015 C 63 AMG (W204) and the 2017+ C43 AMG (W205) use different engines (a 6.2L V8 vs. a 3.0L V6 Bi-Turbo) and therefore have different, non-interchangeable engine sensors and part numbers.
I have a 2016 C-Class that says 'AMG'. What model is it?
For the 2016 model year, Mercedes offered the C 450 AMG Sport, which was the precursor to the C43. It has the same 3.0L twin-turbo V6 engine. Some parts may be shared with the 2017+ C43, but you must verify with the specific part number. The other AMG model was the C 63.
Have there been any recalls for the C43 AMG crankshaft sensor?
Searches of NHTSA data did not show any recalls specifically for the crankshaft position sensor on the C43 AMG models (2017 and newer). Other recalls for wiring and electrical systems have been issued for these vehicles.
