The sensor does control trans.It takes a reading to where the throttle is and tells the trans what gear to be in and when to shift,down shift.So if your getting that reading and the car does not seem to be shifting right suspect that sensor..Hope this helps you and have a great day>>>

If you google 97honda input speed sensor you will find several pictures. (Go to google images and input the above).

IF your input speed sensor goes bad the trans controll unit see's an "incorrect gear ratio".

Check your fluid too. If it is clean, you probably do not have a Major problem I have been rebuilding transmissions since the 80's and only stopped in 06. I have had many that only needed a new sensor like the input or output speed sensor. Try removing the input first and clean off the magnet. It is a pulse width modulator that uses a magnet with lands of metal passing through the magnetic field and the computer counts the pulse made by a collapsing field to determine the speed of the input drum. It compares it to what gear it is in and what the output speed is and if there is a problem it will set the codes you see.

Sometimes find metal from wear in the unit will accumulate on the magnet interfering with the input. Other times the sensor just fails, either way, it is usually not bad unless something is tearing up in the unit to cause a lot of metal to adhere to the mag.

Hope this helps

SOURCE: I have a P0847 code on my 2006 Honda Civic DX.

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.

I got the code P0847 and it says 3rd clutch transmission fluid pressure switch stuck on.. what does that mean and how much will it cost to fix

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.

I have a P0847 code on my 2006 Honda Civic DX. This morning it went into "Limp" mode, I believe. It wouldn't shift past 2nd gear. It shifts past 2nd gear now, but now I have the P0847 OBD II code coming...

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.

Check engine reads P0740 honda civic ex 2001... do i need to replace the transmission control solenoid?

I am sorry to bum you guys out, but this usually means the piston in the torque converter is bad. The converter needs to be replaced along with a transmission flush.
