I have a 1998 dodge caravan 3.3L fault codes p0500 p0700 p0720 p0715, how do I repair and replace sensors to pass smog test


Follow the links for each fault code.
http://www.obd-codes.com/p0500
P0700 Transmission Control System Malfunction
P0720 Output Speed Sensor Circuit Malfunction
P0715 sets when there is an error in the transmission's input speed sensor signal. On the front of the trans there is an input and output speed sensor that the trans controller looks at for shifting control.

While the code could have set because of a wiring or connection problem, it's almost surely the sensor. Input speed sensor failures are not uncommon.

The input speed sensor is mounted right on the front of the trans directly under where the cooler lines attach. It threads directly in and has a 1" hex for a socket for removal. If the wiring and connection look visibly ok then I would recommend replacing the sensor

Replaced input and output speed sensors for erratic speedometer. Now the speedometer remains at 0. Anyone have a suggestion on what else could be wrong?


input and out put speed sensors tell the TCM and the ECM the difference between engine rpms and transmission input roms so that the correct gear ratio can be selected
A speedo sensor reads the out put shaft (drive line ) shaft and refers to road speed for speed and odometer readings and to calculate the fuel consumption rate
it is possible that you have replaced the wrong sensor
Talk with an accredited transmission specialist shop and have the problem diagnosed

My Automatic grand cherokee limited 4.7litres (1999 Model) runs on only one gear without changing on diagnosing the error code P0731 ( gear 1 incorrect ratio) was reported


If you have a scan tool capable of looking at input and output speed sensor data for the transmission that is the first thing I would look at. If you don't than it wouldn't hurt to try a new input speed sensor. They are available from your local NAPA. The speed sensors are located on the drivers side of the transmission. They are a light yellowish white color. it will have a black connector with two wires. The one towards the front is the input speed sensor the one to the rear is the output speed sensor. you will need a 1"socket to remove it.

If replacing the sensor doesn't fix it you will need to bring it in and have it looked at.

The speed sensors are pretty common failures on Chrysler transmissions.

97 Dodge Caravan Sport Once it warms up it stays in second gear until i put it on nutural- shut vehicle off- and then restart it and it will shift fine. What could it be?


The transmission is going into failsafe mode, meaning the computer is seeing an electrical problem and turning off all solenoids locking it into on gear. Best bet is to get a scan tool and read the codes in the transmission module, common problems are the input and output speed sensors. If you are having problems with the speedometer, you probably need an output speed sensor. I've also had problems with pressure switch codes that have lead to replacing the valve body. If you have a speed sensor code i recommend replacing both the input and output speed sensors, they screw into the front side of the transmission.

CANT FIND WHERE THE SPEED SENSOR IS NO MY 1995 OLDSMOBILE AURORA


hi , their is two different speed sensors on your vehicle one is the input speed sensor which is inside the transmission and the transmission will have to be removed to replace it the other one s the output speed sensor is located directly above the passenger side trans-axle shaft. your input sensor is the sensor which tells the transmission when to shift and the output speed sensor tells the speedometer what it should display and both those parts are fairly cheap they are around 15-25 dollars but just remember if your input speed sensor is bad it is gonna cost you a minimum of 1000 dollars to have a mechanic fix as the transmission needs to be removed hope this is what you needed

Sometimes odometer stops working, then seems if you hit a bump it works again


There should be, based on what size engine and whether it is an automatic or manual transmission:
For an Automatic Transmission:
Vehicle Speed Sensor's (plural) on the Transmission An Input and Output Speed Sensor. The one that controls the Speedometer is the Output one.
Before removing and replacing anything - check the connections. Unplug and re-plug the connections. The bump-activation leads me to believe their is a loose connection.
After removing the Sensor's clean the interior ends (their magnetic and may have metal particles covering them - meaning the signals may be interrupted) and re-install and check the operation of the Speedometer.
If it is still intermittent, then replace the Output Sensor.
Which one is Output and which one is Input?
The Output Speed Sensor's inside end is round.
The Input Speed Sensor inside end is hexagon (6-sides).
Don't buy and replace both. Try the Output first. It is about $17 at autozone Part Number is #SU 1034.
The Input is Part #SU 1018 and is also around $17.
FOR MANUAL TRANSMISSIONS:
Part #SU 394. But again check the connection's of both the electrical and attachment to the body before replacing (the "bump" factor). Again also: clean it and reinstall and check operation before buying it at around $45.

I am assuming you have a 4-speed transmission?
There are 2-speed sensor on the front of the transmission. Input and Output Speed Sensors.
They are level with each other, right above the top line of the Solenoid (wiring harness goes into this box-like assembly) The one that is closest to the Solenoid is the Input Sensor. The one (at the same level) towards the left side of the van is the Output sensor.
I believe a 1-in wrench will work, after you unplug the sensors. Torque going-on for both is 20 ft-lbs. Before replacing the sensors - you may remove the sensors and clean the metal particles off the interior tips of the sensors and reinstall and check operations. Start with removal, cleaning, replacing the Output Speed Sensor as the Speedometer Info is directly involved with this. If cleaning does not fix the problem then replace it and check operations, before replacing the Input Speed Sensor. This will save you money from replacing both sensor.

Transmission Input Speed Sensor Replacement 1997 Plymouth Voyager


The first thing I needed to do was to identify my transmission. The 2000 Dodge Grand Caravan Sport (3.3 L) has the A604 transmission, as did any Caravan from 1989 to 2006. Might as well replace both sensor and will take less then 30 min from start to finish.

Vehicle's with A604 transmissions have chronic input and output speed sensor problems and also with the little wire connectors to those input and output speed sensors. The dealer offers a repair kit for these wires instead of buying a whole new wire harness. On most of these vehicles, If you have a code 41-44 you should check for weak battery voltage first. now the shop needs to check the wiring for poor grounds. I have seen that The transmission controller often goes bad causing these same codes, so be careful.

Parts/Tool List:
10mm socket (to remove top of air intake)
1" socket (to remove/tighten sensors)
standard screwdriver (to loosen hose clamps)
Vehicle Speed Sensor - INPUT
Vehicle Speed Sensor - OUTPUT

Removal/Installation:
The first step is to remove the airbox cover. This can be removed with a 10mm socket. Under the airbox cover is the actual airbox; remove the filter by unsnapping the clamps holding the lid in place. Maybe this is a good time to see if your filter needs to be replaced.

Once you've got the airbox cover and filter off, you should be able to see where the sensors are located on the transmission. On the left is the input sensor behind the Transmission Solenoid pack by the transmission dip stick tube , and on the right is the output sensor.

The input sensor is located just under two little hoses; remove the clamps and get those houses of the way. Make sure that you keep track of which hose goes on the left and which one goes on the right. To remove the sensor connector, there's a tab that lifts up, probably under the sensor. It lifts very easily, and the connector slides right off. If it's not coming right off, you haven't properly lifted the tab.

To remove the sensor, you need a 1" socket which should fit right over the terminal. The socket should also be large enough to clear the hose nipples. Note that with both of these sensors, the base is plastic. If you use anything other than a 1" socket, you'll rip the plastic to shreds and never be able to get the sensor off. USE the socket.

In most situation, the output sensor was covered in sludge, which may have been the source of the problem. Both the input and output sensors use some kind of magnetic receiving unit, and those magnets will pick up tiny metal shavings that are suspended in the transmission fluid. I suppose 10 years worth of buildup is enough to cause the sensor to throw bad signals. But maybe something on the inside caused the problem... so replacing it outright was the best decision.

Anyhow, after replacing the two sensors, the transmission problems 98% of the time will completely be resolved. No more weird cruise control issues, no more erratic speedometer, and no more 2-to-1 gear drops when coming to a stop. Problem solved. Good luck and merry xmass
