Tesla Model S

Parking Assist Sensors

Parking Sensor Layout & Part Numbers — Tesla Model S

The Model S uses 12 ultrasonic parking sensors (S1–S12) plus a park assist control module.
The illustrations below show the front (S1–S6) and rear (S7–S12) sensor positions.

Model S front parking sensor layout S1–S6

Front sensors S1–S6

Model S rear parking sensor layout S7–S12

Rear sensors S7–S12

The Model S Service Manual section 1727 – 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.

Retainer – Sensor – Parking Distance
Description Plastic retainer ring/bracket used to secure the ultrasonic parking distance sensor to the fascia opening.
Service Manual reference Retainer – Sensor – Parking Distance (Remove and Replace) — Section 1727
Tesla correction code 17272682
Tesla part number(s) Retainer part numbers are color and fascia–position specific. Match the retainer to your VIN in the Tesla EPC (typical listings are grouped under the 17–Electrical → 1727 – Parking Sensors category).

Sensor – Parking Distance – Inner – Front (S2, S3, S4, S5)
Description Front inner ultrasonic parking sensors mounted across the center of the front fascia, between the two corner sensors.
Service Manual reference Sensor – Parking Distance – Inner – Front (Remove and Replace) — Section 1727

  • AP0 (2012–2016 without Autopilot): 1014388-xx-A radial sensor.
  • AP1 curved corner sensors (S1/S2/S5/S6): 1048473-xx-A (“PARK ASSIST SENSOR – VERSION 2”).

For AP2+ vehicles, confirm whether the car uses the later 11275xx-xx sensor family before ordering.

Sensor – Parking Distance – Inner – Rear (S8, S9, S10, S11)
Description Rear inner ultrasonic parking sensors mounted across the center of the rear fascia between the two outer corner sensors.
Service Manual reference Sensor – Parking Distance – Inner – Rear (Remove and Replace) — Section 1727

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.

Sensor – Parking Distance – Outer – Rear (S7, S12)
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 – Parking Distance – Outer – Rear (Remove and Replace) — 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
  • AP0: 1014388-xx-A radial sensors used at all rear positions.
  • AP1: rear outer positions S7/S12 typically use the radial 1048474-xx-A sensor 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.

Module – Park Assist
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 – Park Assist (Remove and Replace) — 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.

Installation overview — front sensors (S1–S6)
  1. Set the suspension to Very High and enable Jack Mode. Disconnect 12 V power if you will be removing the front fascia completely.
  2. Remove the front under-tray and the wheel-arch fasteners that secure the fascia to the fender liners.
  3. Remove the upper fascia fasteners along the hood latch area and any lower fasteners to release the front bumper cover.
  4. With a helper, pull the front fascia forward a few inches, support it, and disconnect the fog-lamp / side-marker / sensor harness connectors.
  5. On the back side of the fascia, release the parking sensor retainer tabs and push the sensor out of the bumper opening.
  6. Inspect and replace any cracked retainers, then clip the new sensor into the retainer so the face sits flush and level with the fascia.
  7. Reconnect the harness, reinstall the fascia in reverse order, torque fasteners to spec, and test parking assist.
Installation tutorial — rear outer sensor (S7 / S12)

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.

  1. Open the LH front door, lower the LH front window, set the air suspension to Very High, then enable Jack Mode.
  2. At the corner where the rear bumper meets the quarter panel (left for S7, right for S12), remove the small screw/fastener securing the fascia to the body.
  3. Apply masking tape along the paint seam between the quarter panel and rear bumper to protect the finish while flexing the fascia.
  4. Gently pull the bumper corner outward just enough to reach the parking sensor and wiring harness behind the fascia. Do not over-flex the bumper.
  5. Release the connector lock and unplug the harness from the parking sensor.
  6. From the back of the fascia, unclip the sensor from the bracket: depress the small retaining tabs around the sensor body and push it out of the retainer ring.
  7. Inspect the retainer ring and bracket. Replace any cracked, warped, or distorted hardware before installing the new sensor.
  8. Fit the new sensor into the retainer ring with the orientation marks aligned, then clip the assembly into the bracket until all tabs are fully engaged.
  9. Reconnect the wiring harness until the connector lock clicks, then reseat the bumper corner and reinstall the screw/fastener.
  10. Repeat the procedure on the opposite side if replacing both S7 and S12. Exit Jack Mode and return the suspension to its normal setting.

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.
