ISSUE:
The Malfunction Indicator Lamp (MIL) may illuminate with Diagnostic Trouble Codes (DTCs) P0176, P0411, and P0446 being stored in continuous memory on some vehicles. DTC P0176 may be set on vehicles using 100% unleaded gasoline causing the flex fuel sensor to read below the current Powertrain Control Module (PCM) Hz setting of 47.5 Hz. DTC P0411 may occur when the secondary air injection monitor is looking for the front Heated Oxygen Sensor (HO2S) to go lean after the air pump is turned on. DTC P0446 may occur when the PCM sees an out-of-range condition on the Fuel Tank Pressure Transducer (FTPT). A no start/hard start, possible long crank condition and/or stall on engagement on cold start-up at temperatures below 10°C (50°F) may be evident on some vehicles. This condition may be caused by a rich fuel condition PCM calibration.
ACTION:
Replace or reprogram the PCM. Refer to the following Service Procedure for details.
SERVICE PROCEDURE
1. Verify the concern. Perform normal diagnostic routines and service as required.
2. If no other concerns are found, or the concern still exists after service has been performed, check decal to verify vehicle does not have the latest calibration. If it does not, replace or reprogram the PCM using the New Generation Star (NGS) Tester or Service Bay Diagnostic System (SBDS) with the latest calibration CD-ROM. Refer to the following Application Chart for calibrations.
Obtain an Authorized Modification Decal (FPS 8262 - obtainable through DOES II, 251pkg) 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.
