Hello, I need help. My 2003 Dodge Grand Caravan SE has an code P0845. This is an Transmission Fluid Pressure Sensor/Switch "B" circuit. My transmission is an A604 41 ET. Does anybody know where this sensor is located on this type of transmission????

 

I think it's inside the solenoid pack.

 

Without a doubt, all the pressure switches and solenoids are contained within the solenoid pack. If the pressure switch is faulty, you need to replace the entire pack. Just recently picked one up for $85 not including freight.

 

P0845 is a 2/4 hydrulic pressure code, The problems could be a solenoid pack, TRS ( transmission range switch), wiring or TCM ( transmission control module). You could replace the solenoid pack and hope it fixs the problem. I think the question you were asking was where is the sensor for circuit B, That would be part of the TRS. Which is connected the the valve body. and the switch would be part of the solenoid pack.

 

We just replaced our solenoid and are still reading the code saying our pressure sensor is bad can not find the location of the sensor if you or anyone knows the location please let me know we are stuck got the sensor but no where to put it!!

 

Did you find where the TFPS is located?
Need to change mine too

 

Did you ever find it? I can’t seem to find it on mine. Mine is 2012
