- Faulty Engine Control Module (ECM)
How do I fix code P0460 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 = 0353 (Fuel level sensor) (P0460)
- Mercedes Benz Code = 0354 (Fuel level sensor) (P0460)
- Mercedes Benz Code = 0355 (Fuel level sensor) (P0460)
- Mercedes Benz Code = 0356 (Fuel level sensor) (P0460)
Cost of diagnosing the P0460 MERCEDES-BENZ code
The cost of diagnosing the P0460 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

Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Fuel level gauge improper operation
P0460 MERCEDES-BENZ Description
The fuel level sensor is mounted in the fuel level sensor unit. The sensor detects a fuel level in the fuel tank and transmits a signal to the Engine Control Module (ECM). The fuel level sensor consists of two parts, one is mechanical float and the other side is variable resistor. The fuel level sensor output voltage changes depending on the movement of the fuel mechanical float. The fuel level is monitored during vehicle operation to ensure conditions are meet for the misfire detection monitors to run. The level sensor output can be tested with an oscilloscope when removed from the fuel tank.
