Where is the crankshaft sensor located?

Hi christopher and welcome to 2carpros Its behind right side of crankshaft pulley, R/R labor/parts cost -see below

Hello I have provided the directions on how to replace.

Remove or Disconnect: Disconnect negative battery cable Remove serpentine belts from crankshaft pulley Properly raise and support vehicle Remove right front tire and wheel assembly Remove right inner fender access cover Using 28 mm socket, remove crankshaft harmonic balancer retaining bolt

Using special tool J38197, remove crankshaft harmonic balancer

Remove crankshaft position sensor shield Disconnect sensor electrical connector

Remove sensor from block face Install or Connect: Install crankshaft position sensor to block face Tighten bolts Torque Value: 20-40 N-m (14-28 lb.ft.) Install crankshaft position sensor shield Connect electrical connector Install balancer on crankshaft Apply thread sealer GM #1052080 or equivalent to threads of crankshaft balancer bolt Torque Value: 150 N-m + 76 °(110 lb.ft. + 76 °) Install inner fender shield Install tire and wheel assembly Torque Value: 140 N-m (104 lb.ft.) Lower vehicle Install serpentine belt Connect negative battery cable This would take you several hours with the correct tools if you had a pretty good mechanical ability. Hope this helps - let us know
