DTC P0846 - Transmission Fluid Pressure Sensor/Switch "B" Circuit Range/Performance

The pressure sensor codes are the ones to concentrate on first. typically gear ratio error codes are set from internal transmission failures but since you also have pressure sensor codes it may just need a new sensor. Remove the connector to the solenoid pack and check for broken or damaged pins and also see if water is getting into the connector.

The chances are that the sensor is bad. If that is the only code your getting then you might want to replace the sensor. Make sure the trans is full though, as that would make the pressure low and could set the code. Here is where the sensor is.

REMOVAL
1. Raise vehicle.
2. Place a suitable fluid catch pan under the transmission.

1. Remove the wiring connector from the line pressure sensor (Fig. 83).
2. Remove the bolt holding the line pressure sensor to the transmission case.
3. Remove the line pressure sensor from the transmission case.

INSTALLATION
1. Install the line pressure sensor into the transmission case.
2. Install the bolt to hold the line pressure sensor into the transmission case. Tighten the bolt to 11.9 Nm (105 in. lbs.) .
3. Install the wiring connector onto the line pressure sensor
4. Verify the transmission fluid level. Add fluid as necessary.
5. Lower vehicle.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Code PO846


First off check your fluid level. And look for any leaks like side cover trans cooler lines or trans pan.

What does " po846 code" means in a 2002 dodge


2-4 or 2 control pressure rationality problems this means internal hydraulic pressures do not agree with set values created by the computers software program. most likely cause is a internal leak (pressure loss)

Loss of power, transmission issues


code p0700 refers to transmission control system/MIL --malfunction===causes --wiring ---TCM (1)
code po740 refers to torque converter clutch (TCC) solenoid--circuit malfunction===causes--wiring--TCC solenoid--ECM/TCM (transmission control module) (again)
code p0871 refers to transmission fluid pressure (TFP) sensor C -range/ performance problem==causes---wiring--poor connection--TFP sensor--ECM /TCM (yet again)
code p0734 refers to gear 3 ratio (po374 is gear ratio 4) incorrect ratio===causes --wiring--TR sensor/switch--shift solenoids--transmission mechanical fault (causes are the same for po733&734)
code po846 refers to transmission fluid pressure (TFP) sensor B-range/ performance problem===causes ---wiring--poor connection--TFP sensor--ECM/TCM (again). Give the clutch a miss as you still have 1st gear and if the clutch is not working you will not be going any where. Have a pressure test done on the transmission to check for internal mechanical failures (pump ). The rest are sensors are wiring connections , sensor and TCM. My bet is the TCM unit. Have it checked out. What ever you do treat any suggestion of a new transmission with a grain of salt until you are shown proof positive that you need one.

My dodge caravan 3.3L shows 5 malfunction codes what do they mean po455 po846 po500 po700 po732


P0455 = Evap leak monitor large leak detected.
This code usually means the gas cap may have been loose or needs the rubber gasket.

P0500 = No vehicle speed sensor signal.
Vehicle speed sensor is located on the transmission near one of the axle shafts (it may need replacing).

P0700 = EATX controller DTC present.
This simply means you have transmission related codes.

P0732 = Gear ratio error in 2nd gear.
This code is of some concern, it means the transmission is slipping in 2nd gear. However the trans may be in limp mode due to the speed sensor code (limp mode means the trans starts out in second gear in order to at least get to a mechanic). The first thing I would do is have these codes cleared as there may be absolutely nothing wrong with the transmission (especially if you pull the trans dip stick and the fluid does not have a burnt smell. The vehicle should drive normally after that. If the check engine light comes back, have the codes scanned ASAP (before any other unrelated code sets). Chances are it may be the output speed sensor if this happens (easy fix). Hope this helps
