P0188

DTC P0188, sometimes indicated as P018800 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing fuel temperature sensor b circuit high input.

The fuel temperature sensor is used to measure the temperature of the fuel. If the sensor reports a high temperature, it may be indicative of a problem with the fuel system.
One possible solution is to check the fuel system for leaks and make sure that all components are properly functioning. If no leaks or problems are found, the sensor may need to be replaced.
