I was driving my 2005 Nissan Murano on the interstate when I started noticing higher RPMs and started slowing way down. Limped off the next exit with a max speed of about 25 - 30 mph at 4500+ rpms. Turned off the car and waited for a minute. Started it back up and again the car is in low gear. It will move but its like the Transmission never shifts out of low gear. I know its a CVT transmission (variable speed and no real gears) but it not shifting up. Leading up to this about a month before this the AWD and ABS lights came on and I was thinking I have a front wheel hub bearing going out. Since i have check the front tires and I have no play top to bottom tire movement which I think rules out wheel hub bearing. I was getting a rumbling noise up front which also made me think hub bearing... So I replaced the motor last year and replaced the Transfer case about 4 months ago. So ive stuck more money in it than its worth... So i would really like to get it working again and get a few more miles out of it. I really don't think its the transmission as much as something electrical so maybe a sensor. Im wondering if a crankshaft for camshaft sensor could do this or something along those lines. I have the Crankshaft sensor out but it doesn't really look bad... but I don't know the symptoms if it really was bad. Im thinking it just wouldn't start...
Im getting the following codes when i test: I think they were for the transmission and another set for the motor...
One set of test show: P0725 - Engine Speed, P1722 - Vehicle Speed Signal, P1726 - Elec TH Control, P0746 - PC Solenoid A, P1701 - TCM, P1778 - Step Motor, P0868 - Fluid PRESS LOW
Second set show: P1720 - V/SP SEN(A/T OUT), P1715 - in pully speed, P1574 - ASCD VHL ..., P0037 -HO2S2 HTR(Bl), P0456 - Evap very sml leak, P0442 - Evap small leak
Reset the codes and it still does the same thing and they all come back...
Any Help would be greatly appreciated.
Thanks,
Tim
