The only test procedure I see for inspecting the crank sensor is to check air gap between the sensor and teeth on the tone ring. Copy and pasted as follows: CRANKSHAFT POSITION (CKP) SENSOR INSPECTION Inspection of Air Gap NOTE: Perform the following test only when directed. 1. Measure the air gap between each four projections of the plate behind the crankshaft pulley and the CKP sensor using a feeler gauge. If not as specified, adjust the CKP sensor air gap and inspect as follows: Is any of the four projections of the plate behind the crankshaft pulley twisted or bent. If not adjusted, replace the plate behind the crankshaft pulley (See PLATE REMOVAL/INSTALLATION.) or CKP sensor. (See CRANKSHAFT POSITION (CKP) SENSOR REMOVAL/INSTALLATION.) If CKP sensor PID value is out of specification, perform the “Circuit Open/Short Inspection”. Specification 0.5—1.5 mm {0.020—0.059 in} There is also procedure for checking continuity in the wiring harness between the sensor, the computer, fuses and ground.
