97 T+C Speed sensor Throttle Position Sensor or Replace Tranny
I went to the place that I usually use due to this problem: While driving the speed slows like I put it in Neutral and once it gets to about 30 mph it jerks and then drives fine for about 2 or 3 miles and then does it again. Sometimes it slows to complete stop. I experienced what seems like exact same problem in my car and after the TPS was changed everything is fine. The mechanic computer diagnostic checked it and said it was speed sensor and solenoid of Transmission but that I needed new transmission or rebuild. The codes were 54 and 57. Same facility initially misdiagnosed the Throttle Position Sensor and flushed the transmission in the car.

Re: 97 T+C Speed sensor Throttle Position Sensor or...
These are trans codes for spd sensor and gear ratio sensors. has this trans been replaces at any time?
For some reason there are a number of different transmissions that have gone into these vans and have different gear ratios. alot of trans shops put the wrong on in that does fit but improper gear ratios. or just hopfully the sensor did go bad. they usually recommend rebuild due to being half in the trans any ways.
umm i dont know what your asking except if this may need a rebuild? I would say ask whats all included in a rebuild. all trans shops seem to differ in what they call a rebuild but all seem, to have about that same price. these chrysler transmission also seem to have alot of random pressure solenoid and solenoid pack and valve body problems.
if you want shoot back a response in what they all do and ill give you my opinion on if its a fair price for what is begine replaced. get written on paper what is replaced. not verbal.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

P2106 - Throttle Actuator Control System - Forced Limited Power
Engine power and RPM's will be limited and cruise control will be disabled due to a throttle fault. This occurs when one or more throttle positions sensor readings are out of range or do not agree with each other. Sometimes this code is also set if the throttle plate cannot return to the idle position due to carbon buildup in the throttle body (you might try cleaning it). The code can also be caused by a bad mass air flow, output shaft speed, turbine speed sensor, or crank position sensor. If the throttle body is clean, operates smoothly, and no other sensors are failed, then you might have to just replace the throttle body.
Most modern day autos are all electronically controlled, Usually if it detects a fault it can go into limp mode which by default is 3rd gear. The fact your speedo is not working which too is most likely sensor driven then that may be a clue to what is wrong. No speed sensor, no speedo and the transmission control unit is not getting the vehicle speed sense either. So it has no way of knowing what gear to be in or any shift points. I'm thinking it's a sensor issue would be my best guess.
Sounds like a bad out speed sensor.Are you sure you replaced the correct sensor?This trans(AW340)Has an output speed sensor and a vehicle speed sensor.The output speed sensor is located on the side of tail housing just next to where it bolts to transmission case.The vehicle speed sensor will be about midway of the tail housing or on the transfer case tail housing on the 4x4 models.It may be a good idea to have a tranny shop you trust run a diagnostic and see if you are getting output sensor signal to TCM( transmission control module behind glove box)and take a look at TPS (throttle position sensor)signal when it is hot to make sure you replace the correct part.I have seen bad TPS sensors on these jeep not affect engine drivability because the sensor is really two(one for trans and one for engine)thus the two plugs on the TPS sensor for the automatic Cherokee.Good Luck and let me know if I can help.
Use the Phillips screwdriver to loosen the screw in the
intake boot clamp at the throttle body. Slide the intake boot off the
throttle body. Pull the other end of the intake boot off the air filter
Locate the Accord speed sensor at the top of the back side of
the transmission, close to the firewall. It has two 10-mm bolts holding
it in, and an electrical connector at the top. Unplug the electrical
connector by squeezing the clip at the top and sliding it off the speed
Use the ratchet, extension and 10-mm socket to remove the two bolts located on the sides of the speed sensor.
Remove the speed sensor by pulling on it. You may have to twist it back and forth to work it free. If the drive link does not come out with the speed sensor,
remove it from the transmission. The drive link is a very small part
that links the speed sensor with the transmission.
Speed Sensor Installation
Insert the drive link into the new speed sensor. Carefully
place the speed sensor onto the transmission, making sure that the drive
link lines up in the shaft.
Install the two 10-mm bolts and tighten them until they are snug.
Slide the electrical connector back onto the speed sensor until it clicks into place.
Reinstall the intake boot by sliding it over the throttle
body and air filter housing. Tighten the Phillips screw in the clamp at
the throttle body.
Start the Accord and test drive it to verify that the speedometer is working properly.
What sensor are you try to look for?
here is the list of all the sensors for 97 honda civic EX
1.Countershaft Speed sensor
Driven Pulley speed sensor
Engine Coolant Temperature Sensor
Front wheel sensor
Fuel Tank Pressure Sensor
Intake Air Temperature Sensor
Mainshaft speed sensor
Manifold Absolute pressure (Map) sensor
Primary Heated Oxygen sensor
Rear Wheel sensor
Secondary Gear shaft speed sensor
Throttle Position sensor
Vehicle speed sensor.
I hope this can help you, please put something on the ratting. good luck.
There are two speed sensors. One is on the tranny under the throttle bosy and one is under the tranny.
This is the one under the throttle body
This is the one under the tranny near the right wheel.The Countershaft speed sensor is the best bet. i replaced this one on a 1995 honda accord with flashing d4 and after replacement it was gone.the part will be about 125 bucks.
2 airflow sensor out of operating range 3 coolant temp sensor out of operating range 4 oxy sensor indicates full rich 5 throttle potentiometer/airflow sensor... (low throttle pot signal with high airflow sensor signal) 6 throttle pot/airflow sensor...... (high throttle pot signal with low airflow sensor signal) 7 throttle pot...idle fuel adjustment failure(idle speed??) 8 intake air temp sensor...open or shorted circuit to sensor 11 Throttle pot at idle: Throttle pot idle trim out of normal range 12 Airflow meter: MAF signal out of range 14 Coolant thermistor: Resistance out of range or static during engine warm up 16 Air thermistor: Resistance out of range 17 Throttle pot: Out of range 18 Throttle pot/Airflow: Low throttle pot signal at high airflow 19 Throttle pot/Airflow: High throttle pot signal at low airflow 22 Fuel pump drive: ECU output to fuel pump relay 23 Fuel supply: Engine running too rich 24 Ignition Drive: ECU output to ignition Amp 26 Air leak: Engine running too lean 29 ECU self check 33 Injector Drive: ECU output to injectors 34 Injector: Looks for Injector dribble 37 EGR Drive: ECU output to EGR switching valve 39 EGR check sensor: EGR not working (normally pipe blocked) 44 Lambda (O2) sensor: Poor mixture control rich or weak (or misfire) 46 Idle speed Control valve: ECU output to Coil AB 47 Idle speed Control valve: ECU output to Coil CD 48 Idle Speed Control Valve: Stepper motor grossly out of position 66 Air pump: ECU output to air pump relay 68 Road speed sensor: Seen speed < 5km/h at high engine airflow 69 Drive/Neutral switch: Seen cranking in "D" or high airflow in "N" 89 Purge Valve drive: ECU output to purge valve this is all I could find
you don't have a vehicle speed sensor (VSS). You have a wheel speed sensor that tells the PCM vehcile speed in place of the VSS. What are you tring to do?
The electronic engine controls consist of the following:
powertrain control module (PCM) (12A650)
throttle position sensor
idle air control valve
camshaft position sensor
crankshaft position sensor
mass air flow sensor
intake air temperature sensor
heated oxygen sensor—front
heated oxygen sensor—rear
cylinder head temperature (CHT) sensor
power steering pressure (PSP) switch
Wheel speed sensor
The powertrain control module needs the following inputs to calibrate the engine properly:
