DTC P0187, sometimes indicated as P018700 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 low input.

If the sensor is bad, replace it. If the wiring or connector is bad, repair it.
