The QUATTRO FRENI QF61F00423 is an ABS wheel speed sensor, rear right, designed primarily for the Nissan Pathfinder R51 (2005–2012) and sold under both Nissan and Renault S.A. part numbers due to the Nissan–Renault Alliance. The primary OEM references are 479005X01A (current Nissan number, superseding 47900EA001) and 47910EA025 (Nissan front-axle reference, superseding 47910-EA005, also listed in the OEM Application table). The OEM numbers 47900EA001 and 4791070J00 are additional Nissan references for this sensor family.
The sensor operates on the Hall-effect principle: it is mounted at the rear right wheel assembly, where a toothed tone ring (reluctor ring) on the rear axle shaft or hub rotates past the sensor tip. Each tooth passing the sensor induces a digital square-wave pulse proportional in frequency to wheel rotational speed. This signal is transmitted to the ABS / VDC (Vehicle Dynamic Control) control module, which processes live speed data from all four wheels simultaneously.
The ABS module uses this rear right speed signal to detect impending wheel lock-up during braking. If the rear right wheel decelerates faster than the other wheels, brake pressure is reduced at that corner via the ABS hydraulic modulator to restore rotation. The same signal feeds the Vehicle Dynamic Control (VDC), Traction Control System (TCS), and Electronic Brakeforce Distribution (EBD) systems. On 4WD Pathfinder models, rear wheel speed data also supports the four-wheel-drive torque management logic.
On the Nissan Pathfinder R51, Nissan uses a single rear sensor part number (479005X01A) for both rear left and rear right positions — the same physical sensor fits both sides. The product title specifies “Rear Right,” which identifies this unit’s designated installation position. When ordering, confirm the failed position using a diagnostic scanner before purchasing.
Typical signs of a failed rear right ABS wheel speed sensor on the Nissan Pathfinder R51:
Relevant OBD-II / Nissan DTC Codes:
Diagnosis note: Nissan C-codes (chassis codes) are stored in the ABS / VDC control module, not the engine ECU. A generic OBD-II reader that only accesses the engine ECU will not retrieve these codes. A Nissan Consult III Plus scanner, or a compatible professional unit such as Autel or Launch with full Nissan chassis coverage, is required. Before replacing the sensor, inspect the sensor harness and connector for corrosion or chafing, and visually examine the rear axle tone ring for missing, broken, or corroded teeth — a damaged tone ring requires rear axle / hub replacement, not sensor replacement.
Customs description for commercial invoice / declaration: Automotive wheel speed sensor. Final customs classification is determined by the importing country’s customs authority.

Fitment confirmed via parts.nissanusa.com (official Nissan dealer parts catalogue): 479005X01A listed as “ABS Wheel Speed Sensor (Rear)” for Nissan Pathfinder R51 2005–2012; supersedes 47900EA001. Renault S.A. shared the R51 Pathfinder platform and part numbers across Alliance markets. The Nissan Frontier D40 (Navara) shared this sensor family for front axle applications via 47910EA025.
| Part | Reason for Joint Replacement |
|---|---|
| Rear Left ABS Wheel Speed Sensor OEM 479005X01A / 47900EA001 (same part number as rear right) |
On the Pathfinder R51, both rear sensors are the same physical part. On high-mileage vehicles, both rear sensors have been exposed to the same road conditions, moisture, and axle heat cycles. If one rear sensor has failed due to age-related degradation or connector corrosion, the opposite side is often at a similar point in its service life. Replacing both rear sensors as a pair during the same service visit eliminates a second diagnostic call-back and ensures consistent signal quality across the rear axle. |
| Rear Wheel Hub / Bearing Assembly | On the Pathfinder R51, the ABS tone ring is integrated into or pressed onto the rear wheel hub assembly. If the tone ring is corroded, cracked, or missing teeth — a common cause of ABS fault codes that produces results identical to a bad sensor — the hub must be replaced, not just the sensor. During any rear ABS sensor replacement job, visually confirming the condition of the tone ring is essential. If the hub is being replaced, replacing the sensor at the same time is best practice, since the sensor bore will be accessed and the old sensor should not be reused. |
| Rear Brake Pads and Rotors | The rear wheel must be removed for ABS sensor access. Inspecting the brake pads and rotors adds no additional disassembly and no extra labour. On a Pathfinder R51 with high mileage or unknown service history, combining rear brake service with sensor replacement in a single wheel-off job reduces total labour time and avoids a return visit shortly afterward for rear brake work. |
| Front Right ABS Wheel Speed Sensor OEM 47910EA025 / 47910-EA005 |
On the Pathfinder R51, both the front and rear sensors are Hall-effect units exposed to similar road environments. If a rear sensor has failed due to physical damage from road debris or moisture ingress, inspecting the front sensors at the same time is advisable. The front right sensor (47910EA025) is the direct Nissan OEM counterpart in the same sensor family and is available as a companion replacement part. |
| ABS Sensor Wiring Harness | The sensor harness on the Pathfinder R51 runs along the rear axle housing and trailing arm, and is exposed to flex cycling, road spray, and heat from the exhaust. Chafing or cracking of the harness insulation is a known cause of intermittent ABS codes that reappear after sensor replacement. If the harness shows visible damage, brittleness, or discolouration, replacing it together with the sensor ensures a complete and lasting repair. |
