Hello and welcome to Just Answer! I would be more than happy to assist you today.Your code is for the engine speed sensor,

The engine speed sensor is located on the back side of the gear housing, between the fuel injection pump and the air compressor.


Fault Code: 115
PID: P190
SPN: 190
FMI: 2
LAMP: Yellow

No engine speed signal detected at pin 17 of the engine harness.


Engine power derate. Possible white smoke.
