How to solve the fault code p 174 100?

Fault code: P 174 1

Meaning: evaporative emission leak detection pump-low signal

Evaporative emission leak detection pump-low signal

Category: power system

Detailed meaning: the evaporative emission system introduces gasoline vapor from the fuel tank into the storage tank filled with activated carbon, which can absorb gasoline vapor. Then the engine will use fresh air to blow gasoline vapor into the engine combustion chamber. The function of the leakage diagnosis module is to use the leakage detection pump to exert a small pressure on the evaporative emission system and the fuel system, and then detect whether there is leakage in the system to ensure that no harmful steam leaks into the atmosphere.

2. Applicable model of fault code: Mercedes-Benz

Fault code: P 174 1

Throttle Position Sensor, Load Signal-Rationality

Throttle Position Sensor, Load Signal-Rationality

Category: power system

Detailed meaning: Throttle, commonly known as throttle, is a controllable valve used to control the intake of engine. The function of the throttle position sensor is to transmit the throttle opening to the electronic control unit in the form of electrical signal, which is one of the basic parameters to control the fuel injection of the engine.

3. Fault code application mode: Mazda

Fault code: P 174 1

English: Torque Converter Clutch Control-Fault

Meaning: Torque Converter Clutch Control-Fault

Category: power system

Detailed meaning:

4. Applicable model of fault code: mini

Fault code: P 174 1

Meaning: clutch solenoid valve-open circuit

Meaning: The clutch solenoid valve is open.

Category: power system

Detailed meaning: The torque converter acts like a clutch in a manual gearbox, allowing the torque of the engine to be temporarily separated from the gearbox, thus achieving a smooth shift. But the difference is that the torque converter can increase the strength and torque like a downshift.

5. Fault code applicable model: Land Rover

Fault code: P 174 1

English: Torque converter clutch control error.

Meaning: Torque converter clutch control error

Category: power system

Detailed meaning: The torque converter acts like a clutch in a manual gearbox, allowing the torque of the engine to be temporarily separated from the gearbox, thus achieving a smooth shift. But the difference is that the torque converter can increase the strength and torque like a downshift.

6. Applicable models of fault codes: Ford, Mercury and Lincoln.

Fault code: P 174 1

English: Torque converter clutch control error.

Meaning: Torque converter clutch control error

Category: power system

Detailed meaning: The torque converter acts like a clutch in a manual gearbox, allowing the torque of the engine to be temporarily separated from the gearbox, thus achieving a smooth shift. But the difference is that the torque converter can increase the strength and torque like a downshift.
