U0595 Invalid Data Received From Powertrain Control Monitor Module

Check engine lightUsually off

EmissionsNot relevant

Drive cycleNot required

Limp modePossible

A powertrain control monitor module is an independent supervisor that recomputes torque, engine speed or pedal requests and compares them with what the main controller commands, so that unintended acceleration or deceleration can be caught. U0595 is stored when that supervisor's results arrive but cannot be trusted. Ford's 2014 code list contains the partner U0294, lost communication with the powertrain control monitor module, marked with the wrench lamp only, not the MIL. How such monitoring is reported is visible in Ford's 2024 summary: its electronic throttle monitor sets supervision and torque plausibility faults with the wrench lamp, some also with MIL. No manufacturer documents U0595 itself. Drivers should expect reduced power or a limp mode.

Likely causes

Software mismatch between monitor module and main powertrain controller

Monitor module internally faulty

Supply voltage dips or bus disturbances corrupting messages

Symptoms

Wrench or powertrain warning lamp on
Reduced power or limp mode
