Question about 1993 Jeep Grand Cherokee
Two items I'd look at. first would be the sensor itself. If you see contact (scuff) marks on the business end of the sensor you may need to shim it back away from the flywheel a bit. Second, if it's failing electrically, check the actual reference voltage of the system.(usually around 5 volts) If it's too high you may have a problem with the computer (voltage regulator is inside) or a bad system ground. (there are at least five ground points.... on fenders, block and firewall) You also need to check the wiring itself for any possibility of shorting to ground. I can understand having a defective unit once, even twice, but after the fourth one there is definitely something abnormal going on there! You can find good wiring diagrams in chiltons repair manual.
