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 the website.
2. If the concern is a 2001 - 2003 Escape with transaxle shudder, drain, flush and refill the transmission fluid with MERCON(R) Multi-Purpose Automatic Transmission Fluid. Then, referring to the calibration charts (Figures 1 and 2), select the applicable file and reprogram the PCM using the TSB Service Procedure and WDS/IDS release B40.5 and higher. Calibration files may also be obtained at the website.
3. When reprogramming the PCM use blank path programming. Select the proper file from the chart and manually enter the PCM part number or tear tag number to obtain the updated calibration file.
To Perform Blank Path Programming:
1. Connect WDS/IDS to vehicle.
2. Select "16 pin", select "All others, except those below", press TICK.

7. Screen will show "The diagnostic tester is unable to communicate with this vehicle." You will be prompted to "select a vehicle from the vehicle list", press TICK.
8. A list of vehicles will be displayed, select ALL OTHERS, and press TICK.
9. Screen shows "To enable WDS to reprogram the PCM with the correct calibration", enter one of the following: Vehicle Calibration number (7 digits), Tear Tag number (4 digits), or PCM part number, press TICK.
10. Highlight the box next to the selection chosen, and enter ONLY ONE of the selections listed above. Press TICK.
