ISSUE Some 2001-2005 Escape vehicles equipped with a 3.0L engine may exhibit idle speeds outside the specified range. Some 2001-2003 Escape vehicles equipped with a 3.0L engine and CD4E automatic transaxle may exhibit a transmission shudder. ACTION Follow the Service Procedure steps to correct the condition. SERVICE PROCEDURE 1. If the concern is a 2001-2005 Escape with idle speeds outside the specified range: a. Install a new idle air control (IAC) valve with jumper harness included in the kit. The new Denso brand IAC will be installed with the electrical connector facing the opposite direction of the original (Hitachi) valve which is why the jumper harness is required. The original (Hitachi) IAC connector faces the front of the vehicle while the new Denso IAC connector faces toward the rear of the vehicle. b. Referring to the calibration charts (Figures 1 and 2), select the applicable file and reprogram the powertrain control module (PCM) using the TSB Service Procedure and WDS/IDS release B40.5 and higher. Calibration files may also be obtained at www.motorcraft.com.
