• Q: How to replace the Crankshaft Position Sensor on 2004 Cadillac CTS?

  A: Lift and support the vehicle first to change the crankshaft position (CKP) sensor. Unscrew the bolt holding the ckp sensor to the engine block, and remove the ckp sensor and o-ring seal. This requires lowering the vehicle, if it is necessary, to lift all components and pull out components which will be based on the rpo code with the requirement to gain access to the ckp sensor pigtail which may be the requirement of the Wiper Motor module in the case of lhd or in the case of rhd; the removal of the left air inlet grill panels and the removal of the front air inlet panel assembly. After that, you should disconnect the wiring harness connector from the ckp sensor pigtail; remove the pigtail off the retainer. Cut away the tie strap that holds the pigtail to the oil cooler pipes and connect a piece of scrap wire approximately 91 cm (36 in) to the pigtail for later use as a pull wire. Take the ckp sensor pigtail off while watching where it runs and remove the sensor from it out of the pull wire. For the installation the ckp sensor pigtail to the lower end of the pull wire, and use it to guide the pigtail back in place. Unplug the pull wire from pigtail; connect ckp sensor pigtail to retainer and the wiring harness connector. Lift and support the vehicle a second time, clean the mating surfaces of ckp sensor, as well as the engine block, and install the ckp sensor with a new o-rings seal. Mount the bolt fastening the ckp sensor to the engine block and tighten it to 8 n.m (71 lb in). Check the routing of the harness so that it does not touch the Exhaust Manifold, and then lower the vehicle. Depress the ckp sensor pigtail to the oil cooler pipes with a tie strap and install components dependent on the rpo code, tightening the front air inlet panel assembly bolts to the 6 n.m (53 lb in).
