To understand P3180-97, it helps to break down the code into its two diagnostic parts: the base code and the sub-code attribute. nissan p3180-97
If the "Actual" torque deviates from the "Command" by more than 10-15 Nm for more than 2 seconds, the P3180-97 will trigger. If you own a modern Nissan hybrid—specifically the
If you own a modern Nissan hybrid—specifically the Nissan Pathfinder Hybrid, Nissan Infiniti M35h, Q50 Hybrid, or Q70 Hybrid—you might eventually see a warning light pop up on your dashboard. When you plug in an OBD-II scanner, you are greeted with a code that looks different from standard P0xxx or P1xxx codes: . Even without repairs, a lost calibration can cause this code
Nissan’s service manual requires a after any hybrid drivetrain repair. Even without repairs, a lost calibration can cause this code. This requires CONSULT-III or high-end bi-directional scan tool.
The resolver is a high-precision sensor inside the hybrid transmission. It tells the inverter exactly where the motor rotor is positioned. If the resolver signal is noisy or intermittent, the inverter cannot properly control torque delivery, leading to a "-97" plausibility error.
The lithium-ion battery pack naturally degrades over time. When internal cells become unbalanced, the Battery Energy Control Module (BECM) may limit power output. If the ECM requests torque that the degraded battery cannot supply, the difference triggers the P3180-97 code.
