1. At the crank position sensor, check for battery voltage to be present on the Red wire with the key on and cranking. The Black wire should be a good ground and the Blue wire should have 5 volts on it from the computer. One may have to disconnect the crank sensor to check for the 5 volt reference. 2. During crank look for a good 5 volt square wave signal on the Blue wire. 3. Check at the ignition coils for good battery voltage key on and cranking. If there is a loss of voltage during crank check the ignition failsafe relay. 4. Check for any stored engine codes. Crankshaft Position (CKP) Sensor Ignition Failsafe Sensor The ignition failsafe sensor supplies battery voltage to the ignition coils. The ignition coils can look like they have good battery voltage key on but during crank the ignition failsafe relay can stop sending voltage to the ignition coils.

Some 2000-2007 Taurus, 2000-2005 Sable, 2000-2003 Windstar, and 2004-2007 Freestar/Monterey vehicles, equipped with a 4F50N, AX4N, or AX4S transaxle, may exhibit an erratic fluid level reading on the transaxle dipstick and possible leaks around the filler tube and grommet. The condition may be due to a restricted transaxle vent. ACTION: Repair the transaxle vent restriction by replacing the transaxle vent with a 90° vent stem, small hose clamp, two (2) tie raps, and 24″ (61 cm) of 5/16″ (8 mm) vacuum hose. The 5/16″ (8 mm) vacuum hose will be routed from the 90° vent on the transaxle back to the cowl area, next to the brake master cylinder and tie rapped in place with the end of the hose facing down. Refer to the following Service Procedures. NOTE: ON WINDSTAR, FREESTAR AND MONTEREY SEAL THE COWL PANEL GRILLE (COWL TOP VENT PANEL) AREA, SEE TSB 06-14- 10. NOTE: LEAKS MAY BE MISDIAGNOSED AS COMING FROM THE PAN GASKET. ALWAYS FOLLOW WORKSHOP MANUAL, SECTION 307- 01 TO LOCATE THE SOURCE OF A LEAK, AND LEAK CHECK WITH BLACK LIGHT AND DYE. SERVICE PROCEDURE 1. 2. 3. 4. 5. 6. 7. 8. 9. Disconnect the mass air flow (MAF) sensor electrical connector. Disconnect the crankcase vent tube(s) from the air cleaner outlet pipe. Loosen the clamp and disconnect the air cleaner outlet pipe from the throttle body. Release the air cleaner housing clamp(s). Separate the air cleaner cover from the air cleaner tray. Windstar, Freestar and Monterey only: Remove cowl panel grille by following the procedure in TSB 06-14-10. Disconnect the shift cable if located over the top of the vent. Remove the vent, pull straight up on the vent with locking pliers, or carefully pry the vent from the transaxle case. Install the replacement 90° vent stem. Windstar, Freestar, Monterey, Taurus, and Sable with column shifter – Must face to the right rear of the vehicle with the flat edge of vent base parallel to the chain cover boss (Figure 1) Taurus and Sable with floor shifter – Must face to the rear of the vehicle with the flat edge of vent base parallel to the chain cover boss (Figure 2) 10. Install one end of a 24″ (61 cm) long piece of 5/16″ (8 mm) vacuum hose to the 90° vent stem and secure with a small hose clamp. 11. Route the vacuum hose back and up to the cowl area and down next to the brake master cylinder. Carefully tie rap the hose in place next to the brake master cylinder (do not tie rap to brake lines), be sure the end of the hose is facing down and not directly above anything hot. Windstar, Freestar, and Monterey (Figure 3, 4, and 5) Taurus and Sable with column shifter (Figure 6) Taurus with floor shifter (Figure 7)

FORD: 2004-2005 Thunderbird, Explorer LINCOLN: 2004-2005 LS, Aviator MERCURY: 2004-2005 Mountaineer This article supersedes TSB 05-15-4 to correct the Service Procedure. ISSUE Some 2004-2005 vehicles built prior to 09/23/2004 and equipped with the 5R55S transmission, may exhibit a delayed or harsh reverse engagement. This condition may be due to improper pressure control. ACTION It may be necessary to replace the solenoid body assembly. Refer to the following Service Procedure. SERVICE PROCEDURE NOTE INSTALLING TRANSMISSION ADDITIVE WILL PREVENT THE SYMPTOM ON SOLENOIDS THAT DO NOT YET EXHIBIT THE CONDITION BUT WILL NOT RESOLVE THE CONDITION IF IT ALREADY EXISTS. LINCOLN LS AND THUNDERBIRD ONLY 1. Lower the transmission cross member and transmission to gain access to the pressure control solenoid-C (PCC) port. DO NOT disconnect the drive shaft. 2. Install pressure gauge per Step 2 of “DIAGNOSTICS”, below. 3. Reinstall cross member and snug the fasteners for diagnostic purposes only. 4. Proceed with the “DIAGNOSTICS” section of this TSB. 5. After the TSB repair is completed, torque the cross member fasteners to 41 lb-ft (55 N•m). DIAGNOSTICS – ALL VEHICLES 1. Remove pressure tap plug at PCC port (Figure 1).
