Check the fresh air inlet pipe,Some customers may comment that the Service Engine Soon (SES) light is illuminated. Upon investigation the technician may find that Diagnostic Trouble Code (DTC) P0171 has been set.

Cause

The fresh air inlet pipe may have become disconnected from the grommet in the rear rocker cover.

Correction

Inspect the fresh air inlet pipe connection to the rear rocker cover. If the inlet pipe has become disconnected from the rear rocker cover reconnect the pipe into the grommet and also into the metal retaining bracket. Use a plastic tie strap to secure the pipe to the retaining bracket as shown above.

In addition an updated Powertrain Control Module (PCM) calibration is now available to address this condition. Reprogram the PCM with the updated calibration using the TIS2WEB Service Programming System (SPS). As always make sure your Tech 2(R) is updated with the latest software version.
