i was riding along in my 03 neon and it did a surge thing (jerked forward) twice and the cel came on and it popped up a p 0700 and the car went into limp mode i had 1st gear, i think 2nd, and reverse. so is this the speed sensor? if so where is it located so i can fix it? Thanks a million.

 

anyone?

 

This is what I show for the code? Not a speed sensor, unless there is another code?

P0700-TRANSMISSION CONTROL SYSTEM/READ TRANSMISSION
DTCS ON THE DRBIIIt

1 This is an informational DTC letting you know that a DTC(s) is stored in the
Transmission Control Module.
Erase this DTC from the PCM after all Transmission DTC(s) have been repaired.
Using the DRBIIIt, read the Transmission Controller DTC and refer to the
Transmission Category and perform the appropriate symptom.

Anyways...

DESCRIPTION
VEHICLE SPEED SENSOR
The Vehicle Speed Sensor (VSS) is a pulse generator
mounted to an adapter near the transmission output
shaft. The sensor is driven through the adapter
by a speedometer pinion gear. The VSS pulse signal
to the speedometer/odometer is monitored by the
PCM speed control circuitry to determine vehicle
speed and to maintain speed control set speed.
REMOVAL
(1) Raise vehicle on hoist.
(2) Disconnect the speed sensor connector (Fig.
149).
CAUTION: Clean area around speed sensor before
removing to prevent dirt from entering the transaxle
during speed sensor removal.
(3) Remove speed sensor retaining bolt (Fig. 149).
(4) Remove speed sensor from transaxle.
CAUTION: Carefully remove vehicle speed sensor
so that sensor drive gear does not fall into transaxle.
Should sensor drive gear fall into the transaxle
during sensor removal, drive gear must be
reattached to sensor.
(5) Remove speed sensor drive gear from speed
sensor.
INSTALLATION
(1) Install pinion gear to speed sensor (Fig. 149).
(2) Using a NEW o-ring, install the speed sensor
to the transaxle (Fig. 149).
(3) Install the bolt and torque to 7 N·m (60 in.
lbs.).
(4) Connect speed sensor connector (Fig. 149).
(5) Lower vehicle and road test to verify proper
speedometer operation.

 

so do you think im in for a tranny rebuild or replacement?

 

That's only 2 steps harder then changing a friggin light bulb. Can you change a light bulb?

 

For a speed sensor, if that's what that is? Neither...

Just seems the P0700 code means there are more codes stored. What did you use to get the P0700 code? Scanner? Gauge cluster?

 

both, i went to zone and did the key thing and iv been researching the heck out of it and it seems to point to trans control modular, but im wondering if the whole thing needs replaced, im not sure. there are more codes but i have to find them, ihave them written down somewhere. Will the gauge cluster tell you all the codes or just a few of them?

 

I'm not sure of that one. I use an OBDII scanner. I'm sure someone else would know.

 

ok im sure iv got all the codes. 0700 trans control system, 0440 evap emission control (gas cap)? 0755 shift solenoid b malfunction, and 0344 CPS.

 

I can't find the P0755 in the manual, but just looking at the name. I'd think that is the problem with the transmission. If the solenoid doesn't work, neither will the transmission.

This says it only applies to 04's, but I suppose checking the date wouldn't hurt: http://dodgeram.info/tsb/2004/21-001-04.htm
My 03 needs to have the TSB done for the PCM as well, just don't have the $100 to pay for the programming to do so.

P0440-GENERAL EVAP SYSTEM FAILURE
When Monitored: Engine Running. Fuel Level greater than 12%. Ambient Temperature
between 4°C and 32°C (39°F and 89°F)
Set Condition: The PCM does not see the NVLD switch close during the medium/large
leak test. The PCM will then increase the vacuum supply to the EVAP system by
increasing flow through the EVAP Purge valve. If the switch does not close with an
increase in vacuum, an error is detected. Two Trip Fault.
