FUEL SYSTEMFUEL INJECTION CRANKSHAFT POSITION SENSOR TEST
The crankshaft position sensor is sealed, nonserviceable assemblyIf fault code diagnosis indicates problem within this area, test and correct as follows: 1Disconnect main harness connector from ECU2Connect an ohmmeter between the pin terminalsA resistance value of 560 10 at room temperature (20_ C, 68_F) should be obtainedIf resistance is correct, check the mounting, air gap, toothed ring gear (damage, runout, etc, and flywheel key3Disconnect speed sensor connector from wiring harness(the connector with one heavy black lead) Viewing the connector with dual aligning rails on top, test resistance between the terminalsA reading of 560 10 should again be obtainedNOTE: If the resistance is incorrect, remove the screw securing the sensor to the mounting bracket and replace the sensorIf the resistance in step was incorrect, but the resistance of the sensor alone was correct, test the main harness circuit between the sensor connector terminals and the corresponding pin terminals in the main connectorCorrect any observed problem, reconnect the sensor, and perform step again
