Who needs this code 132 DTCs manual
Workshop owners, diesel mechanics, and fleet technicians need this manual when a red STOP ENGINE light is caused by accelerator pedal position sensor 1 voltage below normal or shorted to a low source. It is useful for checking Fault Code 2185 or 2186, confirming Fault Code 131 response, inspecting ECM and OEM harness connector pins, measuring 4.75 to 5.25 VDC sensor supply, and testing for open circuits or shorts with a multimeter.
The procedure describes a severe engine power derate with limp home power only when the code is active. It also notes possible causes including a failed accelerator pedal or lever position sensor, a signal short to engine ground or return wires, or an open circuit in the accelerator signal, supply, or return wire. The guide references INSITE™ electronic service tool use, QuickServe® Online calibration checks, Procedure 019-032, Procedure 019-071, Procedure 019-360, Procedure 019-361, and Procedure 019-031 for related repair actions.
