From what the wire digram is saying the blue and black wire is sopose to be ground. They're not that expensive or hard to replace but I have no idea whether it will cure your problem. If you put your vehicle into drive without proper precautions you will probably end up on someone's Darwin Awards List. I'm sorry, Dan, but you may have to take it in for professional diagnosis. A while back I did get a speed sensor code but it was not my rear diff that was bad.
Also, no significant change in battery voltage was detected during a test of the generator output. As I was backing into my driveway they all came back on again, drove forward, lost the speedometer again too. Hoping its not nothing major. I was thinking about getting the bands agjusted. My transmission slips in 3rd gear. Bernard, Want to thank you for posting so much good info.
This is due to the fact that the transmission is starting out in 2nd gear. Anon, that's too little info for me to even make an intelligent guess. I replaced the output speed sensor,fluid and filter but didn't help. I work for honda and tried to scan for codes but our snap on scanner says it cant communicate with the transmission. Problem with the distributor synchronization circuit. If there are a lot of miles on it, and you have not serviced the transmission regularly, it may be going out.
I pulled over to the side of the road, shut the truck off for 5 minutes. Anon, pumping that much oil through the exhaust can definitely take out the cat. I can't pinpoint your problem for you, Dave, but I can give you a couple ideas. So, 3 sets gone in a matter of 3 days. Some speed sensors are internal to the transmission and will require the transmission to be removed from the vehicle before the sensors can be replaced.
The vehicle has stalled several times when I have needed to break suddenly from moderate speeds. My 2003 Dodge ram 1500 4x4 5. However, it came back in the limp mode with the speedometer going crazy, engine light on again. My light when scanned says its the rear wheel speed sensor. This leads me to believe it may be the transmission speed sensor or something else eletronic. The O2 sensor signal should fluctuate under normal conditions.
I'm a little tight oin funds and was hopeing I could correct this myself. I won't explain where any of the ports are because each person attempting this check should have the proper equipment, safety cautions, and manuals: For checking a transmission similar to the one mentioned in the above post to tell if the problem is in the transmission or the wiring is to put a pressure gauge on the governor port and start the motor. Bull, that happens many times with high mileage vehicles that have not had regular transmission oil and filter changes. And everyonce and awhile it slips in 1st and 2nd but not very often. I'm just a little guy typing this stuff up in my spare time to help and give back to the Do-It-Yourself community. I guess it's time to get rid of this thing. Stalling can happen for a variety of reasons completely unrelated to the transmission.
Hi Bernard, I read through a lot of your post and my problem is similar but has the folks at the Dodge dealership stumped. I've got a 99 ram 1500 with 5. I have a 1999 Dodge Ram 1500 3. The computer may be receiving the correct signal from the sender but not interpreting it correctly. No, Liberty, if you're tired of guessing, you should take it into a professional shop and get it fixed.
I'm sorry, but that's all I can give you without data. Otherwise, please take it in to a shop to have them do it because with that code I believe you're on the right track with replacing them. The instrument cluster assembly has been a problem on those. You then pull the case connector and put the transmission in drive. No other wires go to the tranny. I have replaced both the Rear Differential Speed Sensor and the Transmission Output Speed Sensor but no change. I have to assume you've checked fluid levels, tire pressures, and made sure the brakes aren't locking up.
Sorry, but other than what I've just written I can't give you any specifics without much more scanner data and diagnosis. For checking a transmission like you have the way to tell if the problem is in the trans or the wiring is to put a pressure gauge on the governor port and start the motor. Could it be the govenor? And Where is said sensor on my truck? They will cause harsh up-shifts as can a plugged filter. You should see main line pressure and the trans should go into 3rd gear. I went to a different place ran another computer check and this time the right sensor was given to me, and it was just like the ones you show the pics. It's impossible for me to answer your question in an Internet post.
