Es300, GS430, LS430, Lx470 & RX300

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2002 Lexus SC 430, 2002 Lexus RX 300, 2002 Lexus LX 470, 2002 Lexus LS 430, and 2002 Lexus IS 300. However, it is still accessible from the selected car via links, so may be relevant.

Crankshaft position sensor is located at front of crankshaft, near crankshaft pulley. See Fig 1 and Fig 2 .
Manufacturer lists inspection procedure with crankshaft position sensor removed before checking resistance. On ES300 and RX300, remove passenger's side fender apron for access to crankshaft position sensor. On GS430, LS430 and LX470, remove lower engine cover for access to crankshaft position sensor.

On all models, disconnect electrical connector at crankshaft position sensor. Remove bolt and crankshaft position sensor. Using ohmmeter, check resistance between electrical terminals on crankshaft position sensor. Replace crankshaft position sensor if resistance is not within specification. See CRANKSHAFT POSITION SENSOR RESISTANCE table.
