Long term adaptive memory can change the pulse-
width by as much as 33%, which means it can correct
for all of short term. It is possible to have a problem
that would drive long term to 33% and short term to
another 33% for a total change of 66% away from
base pulse-width calculation.

Fuel Correction Diagnostics
There are two fuel correction diagnostic routines:
• Fuel System Rich
• Fuel System Lean
A DTC is set and the MIL is illuminated if the
PCM detects either of these conditions. This is deter-
mined based on total fuel correction, short term
times long term.
