WARNING:
THIS MODIFICATION IS AUTHORIZED ONLY FOR THE LISTED ENGINE. PERFORMING THIS MODIFICATION ON OTHER ENGINE CALIBRATIONS IS UNAUTHORIZED AND COULD CREATE LIABILITY UNDER APPLICABLE FEDERAL OR LOCAL LAWS.
ISSUE:
The Malfunction Indicator Lamp (MIL) may illuminate and Diagnostic Trouble Code (DTC) P1443 may be stored in memory. There may be no driveability concerns present.
ACTION:
Reprogram the Powertrain Control Module (PCM). The revised calibration will recalibrate the EVAP to test for sufficient flow under normal driving conditions. This should reduce the possibility of the MIL lamp illuminating. Refer to the PCM Application Chart above for correct PCM usage.
When servicing vehicles with MIL lamp illumination and DTC P1443 only, verify Purge Flow Solenoid (PFS) voltage at idle is between 0.9 and 1.3 volts. If so, perform Pinpoint Test HW 19 in the 1997 Powertrain Control/Emissions Diagnosis (PC/ED) Service Manual (use the latest level CD-ROM). If PFS voltage is not in the specified range, proceed to Pinpoint Test HW 18. If the EVAP canister purge valve - PF sensor assembly holds vacuum within the specified range, reprogram the PCM using the latest level CD-ROM.
NOTE:
REGIONAL APPROVAL MUST BE OBTAINED WHEN IT IS NECESSARY TO REPLACE THE PCM.
Obtain an Authorized Modification Decal (FPS 8262 - obtainable through DOES II, 25/pkg) and list the date, dealer number, and summary of modifications performed. Select a prominent place adjacent to the Vehicle Emission Control Information Decal suitable for installing the Authorized Modifications Decal. Clean the area, install the decal, and cover it with a clear plastic decal shield.
