1993 Dodge Caravan 3.0L - Speed Sensor?

Alright. I've pulled a P0500 from my van. I went out and bought a new input speed sensor (just guessing - it may be the output, I don't know yet.)
It's the 3.0L engine, I'm not sure if it's a 3-speed or 4. I haven't been able to find the sticker on the transmission. I have a Haynes manual, which has been useless for finding where the sensor goes. I've also spent hours on the internet, to no avail. It seems to me that the 4-speed has it clearly positioned on the transmission, on the side nearest you. It also seems to me that both of the sensors, on the 4-speed, are near each other and the input is the one between the two cooler lines.
I think I have the 3-speed, because mine is completely different. I know what I should be looking for, but I searched for hours, mainly on the right side of the transmission, and haven't found anything. If anyone knows with certainty where the damn thing is, a diagram or picture would be very much appreciated. Also when describing, please be very clear about orientation (IE "front, if you're facing the...") I have a feeling it's behind/below the engine, on the passenger side, facing the firewall, and it's going to be a real pain to get to without A) taking lots of stuff out or B) jacking the thing up, not really a viable option for me.. otherwise I may as well take it to a mechanic.

    'Front' meaning, if you're facing the engine, closer towards you rather than closer to the firewall, correct?

My van was intermittantly downshifting and/or would not upshift. Also the speedometer was intermittantly unstable, reading between zero and my present speed. I removed the output sensor, cleaned off what appeared to be very fine metal "dust", reinstalled it and it now works fine. I did not even need to replace it. I will now change fluid and filter.I have a 3.3L, with the 4 speed. I also have the shop service manual, which is very difficult to find specific information in. A computer searchable manual would be much better. On the 4 speed, the input sensor is between the oil cooler lines. The output sensor is to the right of it (as you face the front of the vehicle), passed the manual input shaft. They are easily accessed and viewable under the battery. This is perhaps too late to help, but it might be of help to others.

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.
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

1999 jeep Cherokee classic. It will not go into 1st gear. It says it is the input speed sensor. Check gauge light comes on now. I replaced the alternator , input speed sensor and battery. Its over c

It says ? what says? the SCAN TOOL>?

non GRAND, (no engine stated, so fail there 1st)

my guess is you have a DTC and forgot to post that. why do that?

the DTC is covered in the FSM manual, and shows what is failing.

why not read the FSM and do what it says to do?

ill no attempt to read the FSM for you,. and that vague error.

why not log in to and stop guessing. at parts.

there is no reason to gue$$

my guess at he DTC,


or was it the P07xx series, all A/T errors.

P1xxx codes are factory code, got them? need all codes, not just 1 of many. and using a real scan tool not some POS autozoned junk (free)

p0500 is ASE jargon (best ) is VSS sensors.

vehicle speed sensor.

the transmission TCM monitors many inputs, and if they are bad

it can NOT shift, one such sensor is SPEED. MPH or VSS

the tail shaft all all 42RE transmission has a tail rpm sensor

when dead the cars speedometer goes dead, and the TCM

is at a lost to shift to 2nd gear, if speed is 0 all day.

a hopeless deal there.

if the battery voltage is not over 15v, its not overcharging, running.

99 is a nice jeep, id fix mine, ive had many.

the tranny has 2 speed sensors.

the front sensor does not do MPH, its just engine tranny input RPM

there are 3 RPM sensor

Engine, RPM called, CKP

tranny input sensor that tells the TCM true clutch slip at all time

and if the TCC works or not.

the tail shaft is the true speed sensor, vehicle speed, it\'s on tail shaft.

my guess, is the tail sensor is bad and you replaced the front sensor

P-0715 is a bad input sensor

P0720 and up are output sensor errors.

the 500 , is the 3rd sensor, the tail shaft sensor that runs the speedo

1st google hit.

next time post real DTCs

so we can jump on the exact part and the simple tests

the beauty of 3 sensors, is the transmission runs better

shifts better

and the OBD2 diagnostics are dead nuts, accurate.

it can see illegal gear slips (bad clutch packs) in any gear

and tell you. one of the best there.are

if you had new car, with 9speed, good luck keeping that card house going.. really.

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

My shiftinf gear lights and rpm went out on my

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.
Let me know if this helped, or if you have additional information or questions. Feel free to contact me at

Assuming you meant tachometer, not speedometer, then it's the throttle position sensor. I just replaced mine on a 2003 Jeep Cherokee, and they are prone to failure on all Chrysler products, especially if over 70k-80k miles.

Wont change gears after second or from limp gear 92 caravan 3.3 maybe speed sensor? if so where that located on tranny?

The input speed sensor is located just above the solenoid pack (with black cover and multiwire connector) on the transaxle and faces toward front of van. The output speed sensor is to the right of the input sensor about 6" or so. When the hood is open and you look straight down you'll see the solenoid pack. While a sensor could certainly cause the transaxle concern, an internal problem, electrical wiring, controller etc. can produce the same result. If the battery has ever had excessive corrosion/acid builud, it can leak down onto the harness located directly under the battery tray and this has been known to be a problem.
