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)
