Condition
Some customers may comment on intermittent illumination of the MIL/SES. After further investigation, technicians may find DTC P0171. Typically, the concern will occur during stop-and-go, low speed driving, shortly after a hot soak with the air conditioning/cooling fan off, with no engine performance issues will be noted. This is also most likely to occur when the fuel tank is less than half full.
Correction
Technicians should refer to Corporate Bulletin Number 06-06-04-033 for this concern.
