Common Error Codes Covered

This manual provides diagnostic and repair procedures for early Ford EEC-IV two-digit fault codes (applicable to 4.1L EFI models), including:

Engine Codes

• Code 11: System Pass / No Faults Detected (EEC-IV two-digit on-demand and continuous code logic)
• Code 41: Oxygen Sensor Indicates System Lean / No Switching Detected
• Code 23: Throttle Position Sensor (TPS) Voltage Out of Self-Test Range
