P0988 Transmission Fluid Pressure Sensor / Switch E Circuit Range Performance

The Transmission Fluid Pressure Sensor/Switch (TFPS) is usually found attached to the side of the valve body inside the transmission, although sometimes it may be found screwed into the side of the transmission case/body itself.


Anyone know where this sensor is for sure on this Trans?



Typically the causes for this code to set are:
Open in the signal circuit to the TFPS sensor - possible
Short to voltage in the signal circuit to the TFPS sensor - possible
Short to ground in the signal circuit to the TFPS sensor - possible
Failed TFPS Sensor – likely
Internal mechanical transmission issue -possible
Failed PCM - unlikely (programming required after replacement)

If I remember correctly, top rear passanger side of trans housing.

And easy to access.
 
Not my truck BTW.

The trans guy keeps telling me its built into the valve body and has replaced it twice, and is now blaming it on the ECM and the Tuning.

Here's straight from my ATSG 68 guide....
