Nissan Primera P11. After performing a diagnostic check on system two codes coming up as fault codes on the engine: P1232 and P1715. No codes were registered on the Transmission. Can any one help if the battery is disconnected ( ecu reset?) then the car shifts up from 1sst normally and we r stuck i 3rd again

CVT Sensors needs to be checked/changed Both top and bottom...common fault
also not all Scan tools can read this engine/tranny type, some may even tell you that u have no fault......but this guy in La romaine Does Read these type of engines.

P1775 is from the tranny its the Primary Speed Sensor (or its circuit).

P1232 is from the engine ECU probably just 'Tranny fault' or 'ECU safe(limp) mode'

All codes from the tranny are relayed to the ECU, not a lot of ppl have a scan tool that can actually talk directly to the TCM.

Anyway that is the fault u have there for the primary speed sensor.

these sensors were changed but the symptoms remain the same ,, if ecu remains in safe/limp mode how do we reset the ECU ( not by disconnecting battery ) other methord .

Tnx

Well then, the Next step to try is the StepMotor in the tranny.....but these motors are expensive, like $800...so before u buy it, u have to Use the trial and error method to make sure what exactly is the problem.....

what kind of sensors u replaced with, used or new?
if used, it may be also faulty.
