Note: Use the Freeze Frame Data to help you duplicate the conditions that
set the DTC. Pay particular attention to the DTC set conditions, such as,
VSS, MAP, ECT, and Load.
Note: A thorough visual inspection of the Evap system hoses, tubes, and
connections may save time in your diagnosis. Look for any physical damage
or signs of wetness at connections. The strong smell of fuel vapors may aid
diagnosis also.
Note: Refer to any Technical Service Bulletins (TSB's) that may apply.
With the DRBIII in System Tests, perform the LDP Monitor Test. This will force the
