The starter motor of the 2014 Honda Accord is a crucial component for starting the vehicle's engine, playing a vital role in the starting system. Here is a detailed introduction:
Structure and Principle
- Type and Basic Structure14: The 2014 Honda Accord uses a permanent - magnet DC motor as the starter motor. It is mainly composed of an armature, permanent magnets, and brushes. Unlike traditional starters with field windings, it uses permanent magnets as the magnetic poles, which eliminates the power consumption inside the windings, making it more efficient and having a longer service life.
- Working Principle: When the ignition switch of the 2014 Honda Accord is turned to the "START" position, and the automatic transmission is in the neutral position or the clutch inter - lock switch of the manual transmission is closed, the voltage is applied to the electromagnetic coil of the starter motor12. The solenoid in the starter motor then activates, engaging the pinion gear with the flywheel ring gear, and at the same time, connecting the high - current circuit of the battery to the starter motor. The armature of the starter motor rotates under the action of electricity, generating torque, which drives the engine crankshaft to rotate, thus starting the engine12.
Main Parameters8
- Rated Voltage: It is usually 12V, which is consistent with the vehicle's power supply system.
- Power and Torque: The starter motor of the 2014 Honda Accord generally has a power of about 1.4KW, which can provide sufficient torque to meet the starting requirements of the engine. The specific torque value varies according to different engine displacements, but it can ensure that the engine can be started smoothly under normal conditions.
Installation and Maintenance
- Installation Position: The starter motor is usually installed near the engine, close to the flywheel, to facilitate the meshing of the pinion gear with the flywheel ring gear.
- Disassembly and Assembly Steps12: When disassembling, first disconnect the negative battery cable, and then disconnect the positive battery cable. Next, remove the engine harness and the lower radiator hose from the starter motor bracket, disconnect the starter cable from the solenoid pin B, and disconnect the black/white wire from the solenoid pin S. Finally, remove the two fixing bolts of the starter to take out the starter. The installation is carried out in the reverse order of disassembly.
- Common Faults and Maintenance: Common faults include the starter motor not working, weak starting, and abnormal noise during starting10. The possible reasons are battery problems, poor contact of the starter power supply circuit, poor contact of the electromagnetic switch main contacts, or performance problems of the motor itself10. During maintenance, the voltage at the connection of the starter motor can be checked first, and the contact condition of each wiring terminal can be inspected. If necessary, the starter motor can be disassembled to check the condition of brushes, commutators, etc.10.
Replacement Cost6
The replacement cost of the starter motor of the 2014 Honda Accord varies greatly. The price of domestic - brand starter motors is usually around 450 yuan, while the original - brand ones are more expensive, about 1700 yuan. If replaced at a 4S store, with original parts, the price may be between 3000 and 4000 yuan, and the price of aftermarket parts is about 1500 to 2500 yuan. Labor costs also need to be considered, and the overall cost may be around 2000 yuan or more.
