The fuel temperature sensor contains a fuel clog sensor, also of NTC type, assembled on a fuel filter assembly and connected with wires to terminals A15 and A30 of the ECU. When the fuel temperature exceeds 70℃, the ECU will reduce the injection pressure; Engine power is reduced to 60% when fuel temperature exceeds 90 ° C.
The atmospheric pressure sensor is located inside the ECU, which can measure the atmospheric pressure at different altitudes and convert it into electrical signals for the ECU to correct the amount of fuel injection at non-return altitudes.
