How do I replace transmission range sensor for 2002 dodge neon?

I got a diagnosis of my 2002 dodge neon's problem that caused my check engine light to come on and the code that I received was P0705. The definition reads: Transmission range sensor circuit malfunction. then probable cause-open or short circuit condition-poor electrical connection- misadjusted TR sensor- failed TR sensor. That is what my printout reads. My 2002 dodge neon currently has 86,000 miles. How do I replace the transmission range sensor myself? Where is it located? What does it look like? What are the steps? How do I get the part? What price?

Range sensor is located inside the transmission. I will attach the information. Remove valve body assembly from transaxle. (see below)
Remove Transmission Range Sensor retaining screw (3) and remove sensor (1) from valve body.
Remove TRS (1) from manual shaft.
VALVE BODY
Disconnect battery negative cable.
Remove air cleaner/throttle body assembly.
Disconnect gearshift cable from manual valve lever.
Remove manual valve lever from manual shaft.
Disconnect transmission range sensor (TRS).
Raise vehicle on hoist.
Remove oil pan bolts
Remove oil pan
Remove oil filter .
Remove the valve body-to-transaxle case bolts
NOTE: To ease removal of the valve body, turn the manual valve lever fully clockwise to low or first gear.
Remove park rod rollers from guide bracket and remove valve body from transaxle.

CAUTION: The valve body manual shaft pilot may distort and bind the manual valve if the valve body is mishandled or dropped.
ONce you get the valve body out the range sensor is just held in by one t-25 torx screw. When you put the valve body back up seat it against the trans before tightening the bolts, and then torque them to 105 in lbs.
Part number 1 is Transaxle Range Sensor. Part number 2 is Manual valve controlling pin And part number 3 is retaining screw.
You can get new sensor from www.autozone.com

Your printout is right; DTC P0705 means Transmission Range Sensor Circuit malfunction (PRNDL Input).

About this component location, it is inside the Transmission, on the Valve Body. It is called the TRS, Transmission Range Sensor.

GEARSHIFT CABLE
Normal operation of the Park/Neutral Position Switch provides a quick check to confirm proper linkage adjustment. The engine starter should only operate when the transaxle shift lever is in the PARK (P) or NEUTRAL (N) positions.

If the engine starts in any other gear position, or the vehicle rolls when the shifter is in gated PARK (P), a gearshift cable adjustment is necessary.

ADJUSTMENT
1. Loosen set screw and remove knob from shifter handle
2. Remove the center console assembly
3. Adjust gearshift cable as follows:
a. Place gearshift lever in the PARK (P) position.
b. Loosen shift cable adjustment screw.
c. Move transaxle manual lever to the PARK. Verify transaxle is in PARK by attempting to roll vehicle in either direction.
d. Tighten shift cable adjustment screw to 8 N·m (70 in. lbs.) torque.
4. Verify proper cable adjustment. Engine should start with the shifter lever in PARK (P) and NEUTRAL (N) positions ONLY.
5. Install center console assembly
6. Install gearshift knob and tighten set screw to 2 N·m (15 in. lbs.) torque.

Rough idle on 2002 Dodge Neon


Without trouble codes you are fishing in the dark. If the engine has a cylinder that is dead at idle from a fuel injector or ignition problem, it should have a code for a miss on that cylinder. A mechanical problem like a burned valve could cause the problem without setting a code. Have you checked compression on all 4 cylinders ? ?

My 2002 dodge neon has check engine light with coded p0302. I know to try replacing the plug/wires, are there any other common causes for this error code that I should check out?


Hi! When replacing the plugs and wires on this model be sure there is no oil in spark plug wells. You will notice the oil on the plug wire boot when removing it. If there is any oil on any of the boots the valve cover gasket and spark plug tube seals will need to be replaced or the misfire code you mentioned will return. Hope this information helps!

Engine light on 02 dodge neon


If you bought it from a dealer, take it back & speak to them about scanning for codes & if they are going to repair it. If private, I guess your on the hook for having it scanned for codes & diagnosis.

2002 Dodge Neon


the code definition is internal pcm fault. if the car has less than 80,000 miles on it you may have federal emissions warranty left and the pcm would be covered by this warranty. the pcm or engine computer needs to be replaced. i would suggest taking it into a dealer because the new computer needs to be programmed after installation and only the dealer can do that.
