07 G35x 140k miles
Two days ago I come out to see that someone broke into my car.
Lights were left on which resulted in a dead battery.
Got a Jump and all was well...
Took the car for a quick spin and all was still well..
About two hours later I return to the car and the A/T check light turns on and the car is in a fail safe mode!!!! SMH
Feels like I’m in 3rd or 4th gear!!!
I don’t have a check engine light just an A/T check light.
had the car scanned
Got the infamous
U1000 can communication circuit
P0725-Engine speed circuit
P1815- Manual mode switch circuit, no up/down circuit
P1705-Throttle position sensor circuit
Four codes only!!!
Took it to a local tranny guy today and he said it was an electrical problem and wasn’t interested even looking at it..
Can someone give me some insight before I go to someone tomorrow.
Any info or advice is much appreciated

 

Pay the diagnostic fee at the dealer

 

Any insight on what you think the problem might be?

 

Hard to diagnose over the internet but you should start by following the troubleshooting steps in the FSM for each code.

A problem in your wiring harness?
A problem with your ECM?
A problem in your IPDM?
A consult tool at the dealer should be able to quickly localize your problem or you can just keep guessing?
If you have any aftermarket parts, sensors, etc, replace them first with OEM Nissan/Infiniti parts. There are many knockoff cheap Chinese parts being sold to unsuspecting consumers looking for bargains.
Good luck
