P0847 HONDA - 3rd Clutch Transmission Fluid Pressure Switch Circuit Short or Stuck ON https://www.autocodes.com/p0847_honda.html

don't know if your vehicle even has a trans temp sensor. if it did it would be located internally inside the trans pan in valve body. check your trans fluid level, color, and smell. worn trans fluid will cause trans shift issues. burned trans fluid is an indication your clutches are burning and slipping.

code p0847 refers to transmission fluid pressure (TFP) sensor B--low input===causes--wiring---short to ground---TFP sensor--ECM/TCM

Try replacing the sensor and checking the wiring. After that check the transmission control module (TCM)

Does it have any shifting problems? Hard shift or slipping? If not you may just need the 3rd clutch pressure switch. It will need to come from Honda I don't know pricing but I would think less then $100 and shouldn't take long to replace.

make sure the sensor is still plugged in :) it may just need to be replaced. Dont drive until you do, if you can, take to the dealer, should be a less than 200$ fix total.

Only so many places these trans 41 TE can leak on the vans. Lines on top, speed sensors(input, output)one is below the lines the other is to right of the lines. Dipstick tube, trans solenoid gasket, Oil pan & extension gasket. Wipe off & clean area very well. Lines leaking, check clamps first before replacing. Speed sensor leaking replace o ring, Dipstick tube replace o ring, Trans solenoid replace gasket, Extension plate replace gasket If the pan is leaking you change the trans filter & put a gasket on the pan. The book says RTV on the pan, but FelPro make a gasket for the pan $6.99. Use a Chrysler trans filter!!!! O rings for sensors, tube around $3 each, trans solenoid gasket $3, extension gasket $10, Filter $11 + gasket $7 & 4qts trans fluid if doing the filter or extension gasket.

Make sure the trans fluid level is correct. It is, Engine off, ck to make sure linkage is working trans shift lever on trans,,,,,,,,good luck

The governor pressure sensor is the most likley cause however an inspection of fluid or debris in trans pan would be a good idea to make sure there's nothing excessive in it. Attached is a list of possible causes however the senor would be the most common.

POSSIBLE CAUSES

• Powertrain control module
• 5 volt supply circuit open
• Check transmission fluid level and condition
• GOV press sensor signal circuit shorted to voltage
• GOV press sensor signal circuit shorted to sensor ground
• GOV press sensor signal circuit shorted to ground
• GOV pressure sensor signal circuit open
• Sensor ground circuit open
• GOV press sensor signal circuit shorted to voltage inside transmission
• 5 volt supply circuit open inside transmission
• Intermittent governor pressure solenoid
• Internal transmission problem
• Oil burnt or oil pan has excessive debris
• Other transmission DTC'S
• GOV press sensor signal circuit shorted to sensor ground inside transmission
• Valve body
• GOV press sensor signal circuit shorted to ground inside transmission
• GOV press sensor signal circuit open inside transmission
• GOV press sensor ground circuit open inside transmission
• Governor pressure sensor (high)

Probably not a fluid issue. If the fluid is close to right, a little more or less won't matter. Is the speedometer working? If the speedo quits its because the trans output speed sensor has failed. This will cause the trans to lock into limp home mode. I've had good luck in these cases by buying the sensor (about $25) and put it in to see if it fixes the problem. $25 is a cheap experiment. The output speed sensor is very near the passenger side CV joint. Btw the trans and the firewall. Hard to reach. Easy to change. If the speedo is working the problem isn't the output sensor. Maybe the input speed sensor.
