Toyota 90919-05045 Sensor, Crank Position

You can Select Your Vehicle to check if 90919-05045 fits your vehicle.

The Crankshaft Position (CKP) sensor determines the timing for fuel injection and ignition on each cylinder, located at the bottom of the timing chain cover on 2009 and earlier models, while on 2010 and later models, it is positioned at the upper part of the flywheel end of the engine. A problem in the crankshaft sensor circuit will set a diagnostic trouble code. To begin, disconnect the cable from the negative terminal of the auxiliary 12-volt battery and perform the initialization procedure when reconnecting it. For 2009 and earlier models, loosen the right front wheel lug nuts, then raise the vehicle and support it securely on jackstands, followed by removing the wheel. Next, working under the vehicle, remove the lower engine cover and disconnect the wiring from the sensor, which is located next to the crankshaft pulley on 2004 through 2009 models and directly below the oil pressure switch on 2010 and later models. After that, remove the bolt and detach the sensor. Installation is the reverse of removal, ensuring to tighten the wheel lug nuts to the specified torque.
