161 SPN Fault Code

Name:

Transmission 1 Input Shaft Speed

Description:

Rotational velocity of the primary shaft transferring power into the first transmission. When a torque converter is present, it is the output of the torque converter.Note: Single input shaft transmissions should use SPN 161 (Transmission Input Shaft Speed). Multiple input shaft transmissions should use SPN 5960 and 5961 (DCT Input Shaft 1 and 2 Speeds). For maximum compatibility, a multiple input shaft speed transmission may also broadcast SPN 161 as a virtual or current inputshaft speed with the following logic: Transmission Input Shaft Speed = DCT Input Shaft 1 Speed when shaft 1 is engaged. Transmission Input Shaft Speed = DCT Input Shaft 2 Speed when shaft 2 is engaged. Transmission Input Shaft Speed = Transitional interpolated value when shifting between shaft 1 and 2.

161 spn fault code name is Transmission 1 Input Shaft Speed. If you don't take the time to look into 161 spn fault when it arises, it can add up quickly. One small issue like 161 can cause a larger component to become damaged without taking the time to investigate. If you suspect your truck is suffering from one of these issues, look into replacing those small components to save money down the road.

Note: The name and description of 161 code represents text descriptions for faults supported by another coding system and does not necessarily comply with SAE J1939. For a specific engine manufacturer's explanation for codes, please consult the engine's technical manual. See also other spn codes.
