My infiniti QX4 fail at the start, I have to wait for a while and try again and it rus ok!!! When the problem shows up, I move the speed selector from the parking position to 1 position and back several times and sometimes it works and the motor starts running again. I have already changed the neutral sensor in order to avoid the problem (I though it was the problem) nut the fact is that the problem still is the same. Any idea about whats is happening and how to fix it?


Does the starter engage but the engine doesn't start? Have you had the systems computer tested for fault codes? These are basic tests that must be done to start the diagnostics to repair this problem, being that it is intermittent. Have you replaced ... Infiniti QX4

I would suspect you have a short in the wiring to the transmission or the shift solenoid inside the ****** is shorted. Only way to know for sure is to get the wiring diagrams and trace down and inspect all the wiring that the fuse powers. ... 2000 Hyundai Elantra

I have a 2000 dodge stratus and I just changed the input and output speed sensors, but I am still getting the same codes P0700, P0731, and P0733. Before I changed the the speed sensors I was also getting a Po715, but that is gone now. But it seems to stick in second and when I put it into drive it seems to jump into it pretty hard. When I go to accelerate it seems like it jumps into another gear. Already Tried: input and output speed sensors


Stop throwing parts at it and have a professional scanner put on it,by someone familar with your trans type and operation ... 2000 Dodge Stratus

I have a 2000 Chrysler 300m. I had a problem with it about a month ago where the car would rev on its own without me touching the gas peddle, the car would go into limp mode, and it while I was driving it it would rev up without actually increasing my speed. I read that it could be a problem with the input speed sensor. So I changed that. And now a few weeks later it is giving me the same problem. Could something else be wrong with the car, do I need to change the output speed sensor now? Thank

My 05 Pacifica went into "limp in" mode which means it is stuck in 2nd gear. I took it to AutoZone and put it on the code machine. It pulled up P0700, P0715, P0731 and P0733. I changed out hte Speed Sensor Input and Output and still have the same problems but now it only pulls codes P0700 and P0731. Anyone have any ideas? The speedometer and Tachometer all worked before and after the speed sensor change.


Well code 700 is a generic code that means there is a problem with the transmission or the control module. Code 731 is for a problem with first gear which would explain why it stays in second gear.Someone will need to check the circuits involved ... 2004 Chrysler Pacifica

I have a 94 GMC Safari, it won't shift out of 1st gear, the ABS light is stuck on, and the speedo doesn't work. At first the ABS light would come on and off, when the light was on the trans would't shift, when it was off it shifted fine. Now it's stuck on and won't shift. The computer was flashing a vehicle speed sensor code. I changed the vehicle speed sensor and the van still has the problem. There was a trans flush and a front pump seal and rear tail shaft seal, and trans filter changed.

95 Chevy Cavalier with the 2.2 engine in it. The Speedometer does not work and the Odometer doesn't work either But the Auto meter does work. Me and My father thought by changing the vehicle speed sensor that the problem would fix itself. So after changing the sensor the problem still occurs. My next step would be to change the sensors harness. If that does not fix the problem what do you suggest i look into next?
