Question about 2001 Ford Mustang

1 Answer

How do we do an idle relearn on a 2001 mustang 3.8 V6?

My mechanic said that after install of new IAC he wants to do the relearn procedure to establish base idle. Then hunt down poss. vac leaks. He tried the following, which did nothing. Disconnected NEG from battery for 30 minutes. Reconnected battery and started car letting in idle while the engine gets to temperature, then wait one minute. Turn the AC to Max a little over one minute, then turn off. Then go drive the car for about 10 miles. Thanks for your help!

To reset an ECM (CPU) program it will be necessary to use a scanner tool. The idle program is already in the cpu so all it takes is to reset the corrupted cpu program

How do you start the relearn procedure for the crankshaft position sensor on a 2001 Oldsmobile Aurora with a 3.5 liter v6


If there is a relearn procedure, it has to be done with a scan tool from a shop or dealership. In most cases, the crank sensor has no relearn procedure on GM/OLDs products. Instrall a new sensor and the PCM will recognize it and start the engine

Code p0171 and p0507


A P0507 DTC trouble code may be caused by one or more of the following:
A vacuum leak
Leaking air intake after the throttle body
EGR valve leaking vacuum
A faulty positive crankcase ventilation (PCV) valve
Damaged/failed/dirty throttle body
Failed EVAP system
Failed IAC (idle air controller) or faulty IAC circuit.
Possible Solutions
This DTC is more of an informational code, so if there are any other codes set, diagnose them first. If there are no other codes, inspect the intake air system for air or vacuum leaks and damage. If there are no symptoms other than the DTC itself, just clear the code and see whether it returns. If you have an advanced scan tool that can interact with the car, command the idle higher and lower to see if the engine responds appropriately. Also check the PCV valve to see if it's blocked and needs to be replaced. Check the IAC (idle air controller) if equipped, verify it's operation. If available, try swapping in a new throttle body to see if that fixes the problem. On Nissan Altimas and possibly other vehicles the problem may be fixed by having the dealer perform an idle air relearn procedure, or other relearn procedures.

  • 2001-2005 ESCAPE 3.0L UNSTABLE IDLE - 2001-2003 ESCAPE 3.0L AUTOMATIC TRANSAXLE SHUDDER - MEXICO ONLY
Publication Date: May 25, 2006
FORD: 2001-2005 Escape
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:
    1. 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.
    2. 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.
  2. If the concern is a 2001 - 2003 Escape with transaxle shudder, drain, flush and refill the transmission fluid with MERCON® 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 www.motorcraft.com.
  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.
  3. Screen shows installation of cable, press TICK.
  4. Screen shows to turn ignition ON. DO NOT TURN IGNITION ON. Press TICK.
  5. Screen shows progress bar, then screen tells you "No communication can be established with the PCM" and asks you if you want to retry? Select "NO". With the ignition key still OFF, press TICK.
  6. Screen shows to turn ignition ON. Keep ignition in the "OFF" position, press TICK and you will be asked to cycle the key "ON" and "OFF" a few times. Please keep the key position in the "OFF" position through the key cycles.
  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.
  11. Follow and answer correctly all remaining screens. Once PCM is reprogrammed communication should be reestablished and PATS system can be reset (if necessary) per Workshop Manual, Section 419-01.
