** SOLUTION **
Title
Diagnostic Trouble Codes (DTC) P0194-00 - Fuel Rail Pressure Sensor, Circuit Erratic,
Intermittent And/Or P016E-00 Closed Loop Fuel Pressure At Control Limit, Pressure
Too High - US17+OBD16 (Common Rail Fuel System) Emissions And Newer; Model
Year 2017 And Newer
Cause
Common Rail Engines may generate DTCs P0194-00 Fuel Rail Pressure Sensor ( RPS )
and/or P016E-00 Closed Loop Fuel Pressure At Control Limit, Pressure Too High due to
corrosion on the sensor and wire harness terminals. Due to the nature of the fault it may
be difficult or not possible to duplicate the symptoms.
Solution
For all active or in-active occurrences of this fault code complete the following
process:
1. Replace the following parts:
• The Fuel Rail Pressure sensor
• The short internal wiring harness that runs between the connector on the lower
section of the two-piece valve cover and the pressure sensor
Rail Pressure Sensor Harness
2. Apply a liberal amount of locally purchased, Permatex Dielectric Grease part no. 81150
or 22058 to the pin and socket terminals. Do not over-fill the connectors which may damage
the wire seals.
3. Secure the rail pressure sensor wire harness to the connector body with a cable tie to
keep the harness away from the valve train components that move during engine operation.
• NOTE: Ensure that there is enough slack in the wire that there is no tension on the
wires and pins at the connector when securing the cable tie.
