DTC Description: Description

WARNING: This page is about a different car, the 2019 Nissan NV3500 HD, 2019 Nissan NV2500 HD, and 2019 Nissan NV1500. However, it is still accessible from the selected car via links, so may be relevant.

When the selector lever position is P or N, park/neutral position (PNP) signal from the TCM is sent to ECM.

ECM detects the position because the continuity of the line (the ON signal) exists.
