The A1705400917 ABS wheel speed sensor is a front-position replacement part listed for Mercedes-Benz applications. That description narrows the search, but it is not enough to confirm a purchase by itself. The NexuParts product data does not verify a model or year range, so a careful buyer should match the complete reference number and the physical sensor configuration before ordering. This guide explains how to compare the A1705400917 front ABS wheel speed sensor using the information and photos available on the live product page.
What the A1705400917 ABS Wheel Speed Sensor Listing Verifies
The listing identifies the part as an ABS wheel speed sensor for the front position. Its primary MPN and NexuParts SKU are both A1705400917. The same listing also provides 1705400917 and 0844151 as reference numbers and identifies Mercedes-Benz as the compatible make. Inventory is active, and the package includes one sensor.
Those are the verified facts to use during identification. The listing does not establish a specific model, production year, trim, side, diagnostic code, or universal installation procedure. If a marketplace result, old invoice, or third-party catalog adds information that conflicts with the original part, resolve the conflict before checkout.
Why an ABS Warning Does Not Confirm This Exact Sensor
A dashboard warning or stored fault can be a reason to inspect the braking and wheel-speed system, but it cannot identify one exact replacement part. Diagnosis answers what requires service; fitment checking answers which part belongs in that position. Combining those two questions too early can lead to ordering a sensor that looks similar but has a different plug, cable route, mounting feature, or sensor tip.
Use appropriate vehicle-specific diagnostic information first. Once the original sensor or a reliable OE reference is available, compare it with the live listing. Do not select A1705400917 only because the vehicle is a Mercedes-Benz or because the part appears in an ABS-related search.
How to Verify an A1705400917 ABS Wheel Speed Sensor
1. Match the complete OE or reference number
Look for A1705400917, 1705400917, or 0844151 on the original sensor, repair documentation, or a reliable vehicle-specific parts source. Record every character. A partial number or a close-looking number should not be treated as a match. A1705400917 is the primary reference used by the NexuParts listing, while the other two numbers are supporting references.
2. Confirm the required position is front
The product data explicitly identifies the sensor position as front. Do not assume that a rear sensor, or a sensor for the opposite location, uses the same configuration. If the vehicle-specific source identifies a different position, stop the comparison and locate the correct reference before purchase.
3. Compare the connector and visible terminals
Study the plug body in the product photos. Compare its outline, keyed areas, locking feature, opening, and visible terminal arrangement with the original connector. A plug that is almost the same may still be incompatible. Photographing the original connector straight on and from the side can make differences easier to see.
4. Compare the cable and routing features
Follow the cable from the connector to the sensor end. Compare its apparent length, bends, protective sections, clips, and the location of any mounting or routing features shown in the photos. The complete route matters because the cable must correspond to the vehicle's intended front-position layout.
5. Check the mounting area and sensor tip
Compare the mounting tab, fastener opening, sensor-body shape, and sensor tip. Review every product image rather than relying on the first photo. If the OE number agrees but a mounting detail or the sensor profile differs, ask for fitment help before ordering.
A Practical Photo-Comparison Method
Remove visual guesswork by comparing the original part and listing photos in the same sequence. Start at the connector, trace the cable, note each clip or protective section, and finish at the mounting tab and sensor tip. Keep both references oriented in the same direction. A checklist is more reliable than deciding from overall resemblance.
- Reference: Match A1705400917, 1705400917, or 0844151 completely.
- Position: Confirm that the required location is front.
- Connector: Compare the housing outline, keying, lock, and visible terminals.
- Cable: Compare length, bends, protective covering, and routing features.
- Mounting: Check the tab, fastener opening, and its orientation.
- Sensor end: Compare the body and tip shape from more than one angle.
- Photos: Review all live product images against clear photos of the original part.
Keep Different ABS Sensor References Separate
ABS wheel speed sensors can share a general product type without being interchangeable. For example, NexuParts also lists an 89546-0K010 ABS wheel speed sensor for Toyota. It belongs to a different make and carries different OE references. It is useful as a category comparison, not as an alternative to A1705400917.
You can browse the Brake & Control Parts collection for additional products, but every sensor should be selected from its own verified part number, position, connector, mounting details, and vehicle-specific evidence.
Information to Prepare for Fitment Help
If the comparison is uncertain, prepare the product link, VIN, vehicle year and model, required position, the complete number from the original sensor, and clear photos of the original connector, cable, mounting tab, and sensor end. This evidence lets the support team compare specific details. A question based only on the vehicle make or an ABS warning leaves too much unresolved.
Do not install the part while a fitment question remains. A clean side-by-side comparison before installation preserves the opportunity to identify a mismatch and avoids forcing a connector or cable route that does not correspond to the original configuration.
Frequently Asked Questions
Will A1705400917 fit every Mercedes-Benz?
No. Mercedes-Benz is the verified make, but the listing does not verify a model or year range. Confirm the full OE reference, front position, connector, cable, mounting features, sensor shape, and product photos.
Which reference numbers are listed?
The listing identifies A1705400917 as the primary MPN and SKU. It also lists 1705400917 and 0844151 as reference numbers.
Does the listing identify a left or right side?
No specific side is verified in the product data. The verified position is front. Use vehicle-specific information and the original part to resolve any side requirement.
Can an ABS fault code prove this is the correct replacement?
No. A fault code can support diagnosis, but it does not prove the required OE number or physical configuration. Diagnose the system and perform the fitment comparison separately.
What comes in the package?
The verified listing states that the package includes one ABS wheel speed sensor. The product images are the visual reference for the supplied configuration.
Make the Final A1705400917 Comparison
A confident purchase is based on matching evidence, not a familiar make name or warning light. Before ordering an A1705400917 ABS wheel speed sensor, verify the complete reference, confirm the front position, and compare the connector, cable, mounting tab, sensor tip, and every live product photo. Review the current A1705400917 sensor listing, and contact NexuParts before checkout if any detail remains uncertain.
