OBD II error code P0168 is a generic code that is defined as “Fuel Temperature – Too High”, and is set when the PCM (Powertrain Control Module) detects an abnormally high fuel temperature under pre-set conditions for a period time set by the manufacturer.
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 does fuel temp sensor work?
The sensor transmits this information to the Engine Control Unit (ECU) of the vehicle. When the fuel is warm it burns easily, as it’s less dense, the ECU is then signalled by the temperature sensor to inject fuel in the combustion chamber. But, you can expect the opposite if the fuel is dense and cold.
Where is the fuel temperature sensor located?
Right Engine Fuel Temperature Sensor. The right engine fuel temperature sensor is located in the right engine fuel cooled oil cooler. Plug FTMP is connected to the sensor. Open the right engine lower cowling to access the sensor.
How do you change a fuel temperature sensor?
Zitat von Youtube: Part out of the way we'll have more room let's remove the safety clip on that fuel line three quarters deep socket to remove the sensor. Let's take that volume out let's put a rag.
How much does it cost to replace a fuel temperature sensor?
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 temp sensor affect engine starting?
The sensor will not cause a no start. It could cause a hard start and a rich or lean condition only.
