Reference Value Parameter Identification (PID)/Measured Signal Chart

WARNING: This page does not describe the selected car, but rather 27 other vehicles, including the 2021 Lincoln Navigator, 2021 Lincoln Nautilus, 2021 Lincoln Corsair, 2021 Lincoln Aviator, and 2021 Ford Transit-350 HD. However, it is still accessible from the selected car via links, so may be relevant.

The following listing reflects PIDS and/or measured values which may reveal a possible concern within each system shown. Match the category number with the related PID/measured signal and go to the Typical Diagnostic Reference Value Charts.
