Busted Flexplate Question

Did you replace that speed sensor?

No, did not replace that. It was too far in for me, I was too afraid to dig any deeper with all the little things falling out of the transmission. Maybe i should have, what symptoms would that sensor have if it was bad?

AutoZone could read the code for you for free.

Can Autozone read a code from the PCM, or just from the OBDII? I have a OBDII reader but I cant read transmission codes, also this error does not set the CEL so there is no error in the OBDII. I was told that there is another computer in the PCM that stores codes, and that a normal OBDII scanner cannot access these codes. Am I mistaken?

Some scanners can't read vehicle specific codes, only general codes. There could be a code stored even though there is no CEL. What brand scanner do you have? The PCM is the vehicle's computer which stores all of the codes.

This is a thread that I wrote about 2 kinds of internal speed sensors on a 2001 model: http://www.explorerforum.com/forums/showthread.php?t=157488. You should find some of the information interesting even though you have a 96 model. This link is listed in my signature under useful threads.

Is It giving you any symptoms besides the light flashing ? Not a 100% sure but I think if it were the turbine speed sensor you would exhibit some serious symptoms (would not go at all etc?)I was just really wondering if you changed it since you were so close to it and a rebuilder friend of mine said that they change them no matter how old or new it is a an insurance policy?

This is a Quote from Brooklyn Bay that I found About the sensor.

The Turbine Shaft Speed Sensor is mounted on the center support, and measures the speed of the input shaft. The PCM uses the input from this sensor to determine EPC pressure, and TCC control stategy. [Edit: I should add that the computer uses MULTIPLE inputs to determine these things, this is just one, but not the ONLY one!] The input shaft is turning at all times in all gears, and the TSS operates for all gears.

Glacier991 actually said that. His quote was my thread in the link above.
