Re: No 3rd or 4th gear - MAXIMA 00

This morning, I was trying to find the cause of my low voltage... I cleaned both battery post and the terminals... Still voltage is in the high 11V range and now I have the battery sign lit up in the dash...

I'll try to get an output reading on the alternator tomorrow...

I also did a lot of tests on the TCM. All voltage or ohm reading seams to be within spec, expect one. The signal from the "Vehicule speed sensor" on pin #40.

This is what they say:

-Check voltage between TCM terminal 40 and ground while driving at 2 to 3 km/h (1 to 2 MPH) for 1 m (3 ft) or more.

Voltage varies between less than 1V and more than 4.5V.

I tested mine and it jump all over the place. I get all sorts of readings ranging from 0 to 5V. (2.1V, 3.5V, 3.65V etc...). They say it should either be under 1V, or over 4.5V and mine doesn't do that... Even when the car is stopped, it still show 4.5 or 4.6 volts readings! (??)

Now when they say DTC VEHICLE SPEED SENSOR·MTR, what part are they reffering to? The transmission rev sensor, abs sensor, speed sensor in the speedo cluster ???

Again, thx for the help.
