PRNDL INPUT
Transaxle Range Sensor Circuit Malfunction (PRNDL Input).
Check for:
_ Possibly a connector near the shift lever has come loose/dirty contacts, or there is a broken wire from it somewhere going to the TCM
- Corroded or faulty Range Switch.
- Open between Meter Fuse and Range Switch (C136-4).
- Open between Range Switch (C136) and TCM (C229) on one or more circuits.
- Short to Battery between Range Switch (C136) and TCM (C229) on one or more circuits.
- Short between two or more wires between Range Switch (C136) and TCM (C229).
If Meter Fuse is blown, repair any shorts in the Meter Fuse circuit.
P1624 MIL Request Signal from TCM to ECM.This is only a request from TCM to ECM to turn the MIL on. The fault code is stored in the TCM.The Freeze Frame Data is stored in the ECM under the P1624 request code. Be sure to retrieve freeze frame data before clearing code P1624 from ECM.
TCM = Transmission control module
ECM = Engine control module (or more commonly known as ECU)
MIL = Malfunction indicator light (more commonly "check engine light" or CEL)
Good luck and hope this helps

sounds like the trans range sensor or it could be internal trans problem. is the trans shifting ok? if not, it might need an overhaul. the sensor might be something you can tackle but it's on top of the trans right below the air filter housing. it the sensor that the shifter cable is connected to. you'll have to have it in neutral to install it as the sensor has line up marks on it.

I would check the neutral safety switch. It's located on the shift shaft of the transmission and is known to go bad
