Sensor, Crank Position

You should disconnect the negative battery terminal cable as your first step when replacing the Crankshaft Position Sensor. The replacement process starts by removing the fan and generator V belt followed by the generator assembly step and then disconnecting the cooler compressor assembly. The crankshaft position sensor installation begins by disconnecting its connector followed by unbolting the sensor. It is necessary to apply a thin engine oil layer onto the O-ring of the new crankshaft position sensor before installing it with the bolt while tightening it to 10 N.m (102 kgf.cm or 7 ft.lbf) specifications before reattaching the sensor connector. Dismount the cooler compressor assembly while reassembling both the generator assembly and fan and generator V belt. Reconnection and initialization should be performed on the negative battery terminal after putting back the cable according to system requirements.

The crankshaft position service procedure begins with negative battery terminal disconnection followed by V-bank cover removal together with fan removal. The service process starts with generator assembly removal which allows you to separate the cooler compressor assembly by unbolting the suction hose sub-assembly, disconnecting the cooler compressor assembly connectors and removing four bolts that disconnect it from the V-ribbed belt tensioner assembly. First remove the crankshaft position sensor bolt before disconnecting its connector and then extracting the sensor. To install the crankshaft position sensor first lubricate its O-ring using engine oil before installing it with the bolt and torquing to 10 N.m (102 kgf.cm, 7.4 ft.lbf), followed by connecting the crankshaft position sensor connector. Secure the cooler compressor assembly through 4 bolts while torquing to 24.5 N.m (250 kgf.cm, 18 ft.lbf). Subsequently connect the cooler compressor assembly connector and install the suction hose sub-assembly using the bolt which requires torquing to 7.8 N.m (80 kgf.cm, 69 in.lbf). Start by installing the generator assembly followed by the installation of the fan and completion of negative cable connection to the battery terminal while torquing it to 3.9 N.m (40 kgf.cm, 35 in.lbf) and attaching the V-bank cover.

The Crankshaft Position Sensor installation for the 2AR-FE engine control system starts with applying a small quantity of engine oil to the O-ring before making sure the O-ring remains uncracked and untangled. The first step requires applying Toyota Genuine Adhesive 1344, Three Bond 1344 or equivalent to 2 or 3 bolt threads. Use engine oil on the O-ring before installing the sensor with its bolt while tightening both to 10 Nm (102 kgf-cm, 7 ft-lbf). Finally, connect the sensor connector. A post-installation check should identify any oil leakage. Install the rear engine under cover RH as the last step.

Starting the crankshaft position sensor repair process requires several steps including engine under cover and generator removal followed by cooler compressor disassembly using bolt removal to split the suction hose sub-assembly and disconnect the cooler compressor assembly connector until lastly removing 4 bolts from the cooler compressor to V-ribbed belt tensioner. Disable the crankshaft position sensor by unfastening its connector then unholster the bolt and remove the sensor. After applying a small amount of engine oil to the crankshaft position sensor O-ring apply, reassemble it using the bolt while torquing it up to 10 Nm (102 kgf.cm) (7 ft.lbf) then connect the crankshaft position sensor connector. The installation process requires fitting the cooler compressor assembly with 4 bolts at 25 Nm (255 kgf.cm, 18 ft.lbf) torque value while connecting the cooler compressor assembly connector followed by suction hose sub-assembly installation with a torques bolt to 8.0 Nm (82 kgf.cm, 71 in.lbf). Reinstall the generator followed by reinstallation of the engine under the cover.

A proper installation of the Crankshaft Position Sensor requires engine oil application to the sensor O-ring followed by checking for any O-ring damage or positioning issues. The installation requires Toyota Genuine Adhesive 1344, Three Bond 1344 or equivalent to apply to 2 or 3 bolt threads. Install the sensor by fixing its bolt and tighten it to 10 Nm (102 kgf-cm, 7 ft-lbf) while also connecting the sensor connector. Examine the vehicle for oil losses following the mounting process. The installation procedure ends with the Front Fender Apron Seal RH.
