That would depend on which errors are correlated. If they are
disturbance terms (a more correct term than error) between indicators
for a latent variable then they imply something more complicated in your
measures that a simple latent variable. On the other hand, correlation
between disturbance terms for endogenous latents are less likely to be
questioned.

Subject: correlated error terms in SEM
In SEM, the errors are considered latent variables. AMOS software used
either ellipse or circle to represent a latent variable. What is the
implication of correlated error terms?
Thank you.
