P0183 MERCEDES-BENZ code

P0183 is a generic OBD-II code indicating that the fuel temperature sensor A circuit voltage went above calibrated limit specifications during the self test.

What causes P0183 code?

The P0183 fault code can be defined as fuel temperature sensor A circuit high input. It is a generic code which would indicate that the fuel temperature sensor A circuit voltage has gone above calibrated limit specifications during the self test.

Where is the fuel temperature sensor located?

Where is the fuel temperature sensor located? Fuel Temperature Sensor on the right side of the engine. The appropriate engine fuel temperature sensor is housed in the appropriate engine fuel cooled oil cooler. The sensor is connected to the FTMP plug.

What are the symptoms of a faulty fuel temperature sensor?

BAD FUEL TEMPERATURE SENSOR SYMPTOMS

  • YOU SENSE POOR FUEL ECONOMY.
  • YOU READ IRREGULAR TEMPERATURE READINGS.
  • YOU OBSERVE BLACK SMOKE COMING OFF THE EXHAUST.
  • THE ENGINE STARTS TO OVERHEAT.
  • THE CHECK ENGINE LIGHT TURNS ON.

What is the fuel temperature sensor a circuit?

The fuel tank temperature sensor (FTS) is used to determine fuel temperature inside the fuel tank. This information is used by the vehicle’s onboard computer, the engine control module (ECM), to help determine fuel injector control. On most vehicles, the ECM sends the FTS a reference voltage.

How do I fix code P0183?

What repairs can fix the P0183 code?

  1. Replacing the fuel temperature sensor if it tests out of specifications.
  2. Repairing or replacing a defective connector or wiring to the sensor.
  3. Replacing a defective ECM.
  4. Replacing the diesel fuel heater assembly with the temperature sensor.

What does fuel temperature sensor A circuit high mean?

The Diagnostic Trouble Code (DTC) P0183 indicates “Fuel Temperature Sensor “A” Circuit High.” The fuel temperature sensor measures the fuel’s temperature and transmits the appropriate signal to the PCM. Higher signals correlate to colder temperatures and higher fuel densities.

How much does it cost to replace a fuel temperature sensor?

between $231 and $273

Fuel Temperature Sensor Replacement Cost – RepairPal Estimate. The average cost for fuel temperature sensor replacement is between $231 and $273. Labor costs are estimated between $159 and $201 while parts are priced at $72.

Can a temperature sensor cause a car not to start?

The sensor will not cause a no start. It could cause a hard start and a rich or lean condition only.

How do you test a fuel temperature sensor?

You can do a manual check on the Fuel temperature sensor if you want to? Remove it from the engine and you will need a sause pan of water, a thermometer and an ohmeter. Suspend the sensor in the water and slowly heat the water up and note the resistance readings at different temperatures.

Where is coolant temperature sensor?

In most cars, the primary ECT sensor (ECT sensor 1) is installed near the thermostat in the cylinder head or block or on the thermostat housing. A second coolant temperature sensor could be installed in another part of the engine, or in the radiator.
