The Model S uses 12 ultrasonic parking sensors (S1โS12) plus a park assist control module.
The illustrations below show the front (S1โS6) and rear (S7โS12) sensor positions.


The Model S Service Manual section 1727 โ Parking Sensors defines five related components: a retainer, four sensor groups (inner/outer, front/rear), and the park assist module.
Tesla uses several sensor families and part numbers depending on build year and Autopilot hardware (AP0, AP1, AP2+).
Always confirm compatibility by matching the part number on your original sensor or checking the Tesla EPC by VIN.

For AP2+ vehicles, confirm whether the car uses the later 11275xx-xx sensor family before ordering. |
| Description | Rear inner ultrasonic parking sensors mounted across the center of the rear fascia between the two outer corner sensors. |
| Service Manual reference | Sensor โ Parking Distance โ Inner โ Rear (Remove and Replace) โ Section 1727 |
| Typical locations | Rear fascia sensors S8, S9, S10, S11. |
| Tesla correction code | 17271112 |
| Tesla part number family | Same sensor families as the front inner sensors: 1014388-xx-A (AP0 radial) or 1048474-xx-A (AP1 radial), with color-specific suffixes. |
| Description | Rear outer ultrasonic parking sensors mounted at the corners of the rear bumper; these cover the diagonal and side zones when reversing. |
| Service Manual reference | Sensor โ Parking Distance โ Outer โ Rear (Remove and Replace) โ Section 1727 |
| Typical locations | Rear fascia corner positions S7 (LH) and S12 (RH) in the layout diagram. |
| Tesla correction code | 17271122 |
| Tesla part number family |
Match the printed part number and paint code on the original sensor; suffixes (-00-A, -01-A, -03-A, etc.) indicate color and revision. |
| Description | Electronic control module that processes all ultrasonic parking distance sensor signals (front and rear) and communicates with the vehicle CAN bus. |
| Service Manual reference | Module โ Park Assist (Remove and Replace) โ Section 1727 |
| Tesla part number family | Park assist ECU: 1048476-00-x (e.g., 1048476-00-A / -00-C / -00-D / -00-M, depending on revision). Verify the exact suffix by VIN or by reading the label on your original module. |
These rear outer parking distance sensors restore factory parking-assist performance on the Tesla Model S.
They mount at positions S7 (left rear corner) and S12 (right rear corner), using the factory harness and retainer.
Ideal for repairing impact damage, water-intrusion failures, or intermittent โParking Assist Unavailableโ warnings.
| Position | Rear outer corner parking distance sensor (S7 & S12 in the Model S layout). |
| Compatibility | Tesla Model S 2012โ2020 with ultrasonic park assist. Hardware and color must match your original sensor. |
| Typical Tesla OE part numbers |
Choose the option that matches the Tesla part number stamped on your original sensor, or contact us with your VIN. |
| Connector | Factory-style 3-pin ultrasonic sensor connector. |
| Mounting | Clips into rear fascia bracket with the OEM retainer ring; sensor face sits flush with painted bumper surface. |
| Calibration | No software coding required when replacing like-for-like. Verify operation with a parking-assist test after installation. |
This summary is based on the Model S Service Manual procedure for the rear outer parking distance sensor.
Always observe high-voltage safety, support the vehicle correctly, and wear appropriate PPE.
After installation, gently pull on the connector to confirm it is latched, make sure the sensor face sits flush with the bumper,
then test the parking-assist system in a safe area by slowly approaching obstacles while monitoring the visual and audible alerts.
