Part Number to this Dillywhomper?

Hi,

Anyone know the part number or where I can get this sensor? I went to two local parts stores and they had no idea. Its the sensor that is on the timing cover. I have 93 7.3, 4x4, automatic. I have some shifting problems and Im positive its this sensor causing my issues.





sorry if the pic is huge.

it gives ya the rpm readings.

usually tach sensors are tied to the timing of the shifting on an automatic

Hrm. I hadn't thought of that... The only problem I have ever had with the IDI trucks not shifting right is either the Throttle Position Sensor being mis-adjusted, or the plug on the TPS being faulty. I would start there, personally. Is the Tach sensor just nasty looking, or is the wires on it completely gone? It might still be working, provided there are wires on there, and the problem in that case would be the TPS.

You know, after another look at the picture (great detail by the way) the Tach sensor doesn't look that bad to me. I would clean it up with some brake clean, and inspect it really well. All mine look far worse than that, and the transmissions still shift. Like I said before my problems were with the TPS.

This is a very simple engine. It's really not more complicated than a tractor engine. I am really leaning toward this being a TPS problem. I really think the Tach signal is just for the tach or for engine diagnostics (via the diagnostic connector behind your left headlight). I know for sure that if your TPS wires are loose or the TPS is our of adjustment, then your tranny won't shift right at all.
