Prices for Honda solenoids vary widely by type and model. In practice, starter solenoids are usually sold as part of the starter, so replacement costs reflect the starter unit rather than a separate tiny component. Standalone solenoids used in fuel systems or transmissions typically run much smaller per unit, often in the range of a few tens to a couple hundred dollars depending on OEM vs aftermarket parts. Labor costs are additional and depend on your vehicle and local shop rates.
In more detail, this article breaks down the common solenoid types found in Honda vehicles and the typical price ranges you can expect from dealers, aftermarket suppliers, and repair shops. Remember that model year, the exact part, and whether you choose OEM or aftermarket will influence final costs.
Common solenoid types and price ranges
Starter solenoid (usually part of the starter)
The starter solenoid is typically integrated into the starter motor in most Honda models. When you need to replace it, you’re often buying a whole starter unit rather than a separate solenoid component.
- New OEM starter: roughly $300–$700, depending on model and seller.
- Remanufactured starter: roughly $150–$350.
- Aftermarket starter: roughly $100–$500.
- Labor to install a starter: roughly $100–$300, depending on shop rates and accessibility.
Note: Because the solenoid is usually part of the starter, many owners opt for a complete starter replacement rather than a separate solenoid piece.
Fuel injector solenoids
Fuel injector solenoids (the coil portion inside each injector) control the spray timing and are specific to each injector. Replacing injectors or their coils can be necessary if a cylinder misfires or fuel delivery is compromised.
- Per injector coil/solenoid: about $40–$180, depending on OEM vs aftermarket and model.
- Complete fuel injector (including solenoid components): about $120–$350 each.
- Labor to replace a single injector: roughly $60–$200; replacing multiple injectors can raise total costs significantly (often $400–$1,200 or more for a full set on a four-cylinder engine).
Prices can vary with engine size (e.g., 4-cylinder vs 6-cylinder) and the specific Honda model year.
Automatic transmission solenoids
Transmission solenoids regulate hydraulic control in the valve body and are common in many automatic Hondas. When faulty, the transmission may shift harshly or fail to engage gears properly.
- Per solenoid: about $40–$120.
- Labor to replace a solenoid: roughly $60–$150 per solenoid; replacing multiple solenoids or accessing the valve body can raise costs.
Transmission solenoid prices vary by generation and transmission type, and some repairs may require additional components or a drain and refill procedure.
Other solenoids (EGR, purge, vacuum/vent solenoids, etc.)
Honda vehicles also use various small solenoids for emissions control and vacuum systems. These tend to be cheaper per unit but can add up if several solenoids fail or require replacement during a repair.
- Other solenoids: roughly $20–$80 each.
- Labor to replace individual solenoids: about $40–$120 per job, depending on accessibility.
Keep in mind that availability and exact part numbers vary by model, so an accurate quote requires your specific Honda model, year, and trim.
What affects the price
Several factors influence solenoid pricing for a Honda: the type of solenoid, whether you buy OEM or aftermarket parts, how many units are involved, and the labor rate at your chosen shop. Starter-related costs often dominate the total when the entire starter must be replaced, while fuel injector and transmission solenoids can add up quickly if multiple units are required. Always confirm the exact part number and compatibility with your vehicle before purchasing.
Summary
Honda solenoid costs vary widely by function and model. Starter solenoids are typically tied to the starter unit, with replacement often priced as a complete starter (roughly $100–$700 for the unit and $100–$300 for labor). Standalone solenoids, such as those for fuel injectors, transmissions, or emissions/engine systems, generally run from tens to a few hundred dollars per unit, with labor adding to the total. For the most accurate estimate, identify your exact Honda model and year, confirm whether the solenoid is sold separately or as part of another component, and obtain quotes from multiple parts suppliers or repair shops.
