Diagnostic Aids

WARNING: This page is about a different variant/trim than selected.

This DTC may be set with a misfire DTC, however the existence of this DTC is a higher priority and indicates the condition to diagnose is related to fuel and/or injectors, not the ignition/spark system.
A restricted fuel injector may cause this DTC to set.
High resistance in the circuits of the injectors could set this DTC without setting an injector DTC. Test the injector circuits of the affected cylinders for a high resistance if you suspect a condition.
A drop in system voltage during cold start may set this DTC.
