OEM numbers
Toyota checked position paths: front LH SU003-00663, front RH SU003-00662, rear RH SU003-00664 and rear LH SU003-00665. Subaru checked rear RH 27540CA020 and front LH 27540CA010 paths.Supersession
No side or axle interchange asserted. A wheel-speed DTC can originate in sensor, harness/connector, air gap, debris or hub/reluctor damage.
Fitment
First-generation only. Decode the DTC position, confirm left/right and front/rear, and inspect wiring and the encoder/reluctor before ordering. Excludes second-generation and generic universal sensors.
Aftermarket options
Checked OEM position-specific and exact aftermarket/marketplace paths. Marketplace descriptions require part-number and position confirmation.
Before you buy
Four positions use distinct catalog paths. Confirm the DTC location and test wiring/encoder condition; a stored sensor code does not by itself prove the sensor is bad.
