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.

Customer Concern: Tests/Procedures: Potential Causes: Tech Tips: Diagnostic Codes: The check engine light is on with a trouble code P1140. 1. Check the right side (passenger side) Intake Valve Timing Control Position (IVTCP) sensor for 12 volts on the Black/White wire. 2. Check the IVTCP sensor for a good ground on the Black wire. 3. Scope the Yellow/Green signal wire and look for a square wave signal of around 8 volts. Check the pattern of the right side sensor and if unsure of the pattern, compare it to the left bank sensor. IVTCP Sensor Wiring — IVTCP sensor wiring/connection. This code is for the right (passenger) bank IVTCP Sensor or sensor circuit. The right and left bank sensors can be swapped from side to side to see if the code will follow the sensor. The sensor is on top of the timing cover. P1140

Removal (3.8L – VIN K) 1. Release fuel system pressure. See FUEL SYSTEM PRESSURE RELEASE . Clean the fuel rail assembly and connections. Disconnect the fuel feed pipe and return pipe at the fuel rail. See FUEL LINE DISCONNECT FITTINGS . 2. Disconnect the vacuum line from the fuel pressure regulator. Remove the ignition coil wires. Disconnect the 6 injector electrical connectors. Remove the fuel rail hold-down bolts. Remove the fuel rail with equal force on both sides of the fuel rail. 3. To remove injector(s) from the fuel rail, remove the fuel injector retainer clip. Remove the fuel injector from the fuel rail. Remove and discard the fuel injector upper “O” ring. Installation

Refer to System Wiring Diagrams . COMPONENT LOCATOR THEFT DETERRENT SYSTEM COMPONENT VIEWS Callout 1 2 3 THEFT DETERRENT SYSTEM CONNECTOR END VIEWS Passlock Sensor Terminal Identification Component Name Passlock(tm) Sensor Connector Ignition Switch Connectors Ignition Switch DIAGNOSTIC STARTING POINT – THEFT DETERRENT Begin the system diagnosis with Diagnostic System Check – Theft Deterrent . The Diagnostic System Check will provide the following information: The identification of the control module(s) which command the system. The ability of the control module(s) to communicate through the serial data circuit. The identification of any stored diagnostic trouble codes (DTCs) and their status. The use of the Diagnostic System Check will identify the correct procedure for diagnosing the system and where the procedure is located. DIAGNOSTIC SYSTEM CHECK – THEFT DETERRENT Test Description The number(s) below refer to the step number(s) on the diagnostic table. 2: Lack of communication may be due to a partial malfunction of the class 2 serial data circuit or due to a total malfunction of the class 2 serial data circuit. The specified procedure will determine the particular condition. 5: The presence of DTCs which begin with “U” indicate some other module is not communicating. The specified procedure will compile all the available information before tests are performed. 6: The listed DTCs are internal module malfunctions and should be corrected before attempting any other diagnostics. 7: The listed DTCs are battery voltage related malfunctions and should be corrected before attempting any other diagnostics.

Do not connect battery trickle charger. Risk of Injurywhen performing diagnostic tests and repairs on components of the SRS system. Store both airbags and side airbags with opening surface pointing upward. Do not expose to temperatures above 100°C . Preliminary work: Diagnosis – Function Test. See: FT – Function Test Preparation for DTC Readout : 1. 2. 3. 4. 5. Review DTC Memory and Actual Values. Fuses OK. Battery voltage 11 – 14 V SRS MIL (A1e15) illuminates. Connect Hand-Held Tester (HHT) as per connection diagram and readout DTC memory. WARNING: Interrupt any electrical current from reaching the airbag unit. NOTE: As of 07/93, diagnostic trouble codes (DTC’s) can only be read out and erased using the Hand-Held Tester (HHT). Determine MB number of the SRS control module via HHT (See DTC Chart). The SRS control modules beginning with the number 000, the fault code 1 is valid. Those beginning with 001, the fault code 2 is valid. NOTE : When installing additional accessories, observe harness clearances near SRS sensor lines. Test equipment : Hand-Held Tester (HHT) (Available through the MBNA Standard Equipment Program.)
