__FORCETOC__

== 16474/P0090/000144 - Valve for Fuel Metering (N290): Open Circuit ==

== Possible Symptoms ==
* MIL (Malfunction Indicator Lamp) ON
* Loss of power (limp mode) possible
* Difficulty starting engine (extended cranking or no start)
* Increased emissions
* DTC stored in ECM

== Possible Causes ==
* Open circuit in wiring to Valve for Fuel Metering -N290-
* Faulty Valve for Fuel Metering -N290-
* Faulty Fuel Pressure Regulator Valve -N276-
* Poor electrical connections (loose, corroded, or damaged pins)
* ECM power stage fault

== Possible Solutions ==
* Check wiring and connectors to Valve for Fuel Metering -N290-
* Check Fuel Pressure Regulator Valve -N276-
* Repair or replace wiring/connectors as necessary
* Replace faulty Valve for Fuel Metering -N290- or Fuel Pressure Regulator Valve -N276-
* If no fault is found in wiring or components, suspect ECM internal fault
* Measure resistance between component connector terminals 1 and 2
** Specified value: 1.5 – 11 Ω (±0.5 Ω @ ~20 °C) ''(verify ALL values with official repair information!)''

== Monitoring Conditions ==
* Signal voltage < 4.70 V
* Power stage = permanently high
* Duration ≥ 0.20 sec.
* Continuous / 2 DCY

== Special Notes ==
* The [[Fuel Metering Valve -N290-]] and [[Fuel Pressure Regulator Valve -N276-]] may be referenced differently depending on engine family.
* Always verify wiring integrity before replacing components.
