I have a 1999 plymouth Voyager 3.3 Auto4 spd with 190,000 miles. Speedometer stopped working so I scanned the computer and came up with 3 codes. MIL did come on. I understand that PO500 is the vehicle speed sensor. How dificult is it to change and where is it located? What would the other 2 codes mean? It seems to be going into reverse a little harder then normal. Fluid is ok. No leaks. No unusual noises. I expected this to happen sooner or later. Any help? Thx

 

replace the output speed sensor on you 4 speed trans, 3.3 engines only have 4 speed tansmissions. The output sensor is localed next to the transfer gear. Or if you are looking the two sensors, it would be the one on the right.

 

What do you think the other codes are calling? I am getting a little buck when I drove it around the block.

 

Your transmission is going into limp-in or fail safe mode. P0500 = speed signal, P700 = PCM has a transmission code in the EATX controller, and P0731= Gear ratio error in 1st. Replace the output speed sensor and clear the codes.

 

Thanks for the great input.

 

I have a (02) Grand Caravan Sport getting the engine code of p0700. Would replacing the output speed sensor clear the only code?

 

I had the output speed sensor replaced and it cleared all 3 codes. It seems to cause a lot of problems when this sensor goes bad. So yes would be the answer.

 

Replaced the output speed sensor (5 - 10 minute fix), cleared the p0700 code; so far - so good...

 

Hello deezozdodge!! You reported in Jan. of 2008 that you replaced the output speed sensor; and after clearing the codes, all was well. Well it is now Sept. 2008 has the p0700 code still remained off? I ask because I have a 1997 Caravan/3.3L/4 speed AT and it is now displaying a p0700 & p0740 code. I'm hoping that replacing the output speed sensor may solve my problem!
Thanks GTOMIKE

 

I am working on a 2003 dodge neon 2.0 and the code was po731... I changed the sensor three times and it is stuck in limp mode???? What do i do to fix it
