ISSUE Some 2001-2005 Taurus/Sable, 2001-2006 Escape and 2005-2006 Mariner vehicles built prior to
1-17-2006 equipped with the 3.0L 4V Duratec engine may exhibit a ticking noise from the left bank cylinder head, with the engine at normal operating temperature only.
ACTION To diagnose, with the engine running and warm (normal operation temperature), using a mechanic’s stethoscope determine if the ticking noise is coming from the left hand intake camshaft at cylinder number 6, (Figure 1). If the ticking noise can be verified, refer to the following Service Procedure.

NOTE: Ford DOES NOT provide procedures to retrieve or clear trouble codes without the Super Star II tester. The anti-lock brake/traction assist system has on-board diagnostic capabilities. However, the module as received from manufacturing is equipped with a stored error code (61). This will affect the service procedure. The error codes can be retrieved from the ABS module in the following manner. 1. 2. 3. 4. Connect Super STAR II tester to connector located in engine compartment on the power distribution box. Turn on Super STAR II tester and latch button down in TEST position. Turn ignition switch to RUN position. Read first code output. After approximately 15 seconds, the next code will be output. Leave button latched until all codes are output. NOTE: Make sure that all codes are written down. 5. The diagnostic procedure should be as follows provided that the CHECK ANTI-LOCK BRAKE indicator stays on all the time or flashes intermittently. NOTE: If the BRAKE warning indicator is on or intermittently comes on, refer to the Warning Indicator Symptom Chart. NOTE: If there are more codes stored in the anti-lock brake control module memory, no codes will erase until all codes have been output by the Super STAR II tester, all malfunctions have been serviced and the vehicle is driven about 40 km/h (25 mph). This means that if a 20s code originally existed and was serviced, it can be ignored when running the on-board diagnostic the second time. If the first code received is 18, 19 or in the 20s and no other code is received, service the indicated component. No other codes can be output if a 20s code exists. After servicing the indicated 18, 19, or 20s code, repeat the procedure for retrieving error codes. 6. If a code 61 is received with any other code, ignore the code 61 and service the other indicated components. If, after correcting all other indicated malfunctions, the CHECK ANTI-LOCK BRAKE indicator is still on, service the Fluid Level Switch (FLS) circuit. 7. If a code 61 is received and no other codes are received, service the FLS circuit. 8. If no code, or only a code 10 is received, use the Anti-Lock Quick Check Sheet since some possibilities are not recognized and retained in the anti-lock brake control module memory. See: Trouble Code Descriptions/Quick Check Sheet 9. When dealing with intermittent ABS warning light ON concern, make certain to visually inspect all wiring related to the component associated with the code received.

Some control modules don’t have a serial link. To read the fault code, you will have a to use a different method. Bridge pin A and B in the diagnostic connector Turn the ignition on Count flashes in the check engine lamp Translate them using the list below To erase the fault code disconnect the battery for 30 seconds Blink code interpretation The code read out always starts with “Code 12” repeated three times, the fault codes are flashed. All codes are repeated three times, the first digit is flashed with a space of 0.4 seconds, then there is a 1.2 second delay until the second digit is flashed. The delay between codes is 3.2 seconds. The sequence is ended by once again flashing of “Code 12” three times.

Steering Vibration/Shudder/Moan During Parking Maneuvers on Dry Pavement (Install Power Steering Pressure (Inlet) and/or Return (Outlet) Hose Assembly) 1995-99 Buick Riviera 1997-2001 Buick Park Avenue, Ultra 2000-2001 Buick LeSabre 2000-2001 Pontiac Bonneville steering vibration, shudder or moan noise when steering during parking maneuvers on dry pavement. Correction Install a new power steering pressure (inlet) hose assembly on the following vehicles: • 1995-98 Buick Riviera • 1997-98 Buick Park Avenue and Ultra Install a new power steering pressure (inlet) and return (outlet) hose assembly on the following vehicles: • 1999 Buick Riviera • 1999-2001 Buick Park Avenue and Ultra • 2000-2001 Buick LeSabre • 2000-2001 Pontiac Bonneville 1. Verify that the power steering pump reservoir is full. • If fluid level is low, fill and check for leaks. • If power steering system has air in the system, perform the “Bleeding Air from Power Steering System” procedure as described in the Power Steering System sub-section of the Service Manual. Important: When performing the “Bleeding Air from Power Steering System” procedure, it is important that the front of the vehicle is supported by the lower control arms. If the vehicle is not supported by the lower control arms, the procedure may cause the strut bushing to dislocate and cause new concern. Verify that the accessory drive belt is in good condition and that the pulleys are not bent or damaged. Verify proper belt tension and operation of the belt tensioner. Check for power steering hose ground out conditions. Check for good engine idle and correct engine RPM. Check to see that the rear transaxle mount does not have a plastic assembly aid installed which is used 2. 3. 4. 5. 6.
