Common Error Codes Covered

This manual provides diagnostic and repair procedures for early Ford two-digit and three-digit fault codes (where computerized fuel systems are equipped), including:

Engine Codes

• • Code 11 / 111: System Pass / No Faults Detected (EEC-IV pulse diagnostic logic baselines)
  • Code 41 / 172: Oxygen Sensor Indicates System Lean / No Switching Detected
  • Code 21 / 116: Engine Coolant Temperature (ECT) Sensor Signal Out of Range
  • Code 23 / 121: Throttle Position Sensor (TPS) Voltage Out of Self-Test Range
  • Code 95 / 542: Fuel Pump Secondary Circuit Failure / Open Circuit Detected

Mechanical System Diagnostics

• • Ignition Module Faults: Pinpoint testing paths for tracking loss of signal at the TFI or EDIS module.
  • Mechanical Fuel Pump Testing: Delivery rate and pressure testing metrics for standard carburetor fuel pumps.
  • Distributor Advance Failure: Measuring steps for checking centrifugal or vacuum load advance systems on early HCS and CVH engines.

ABS and Chassis Faults

• • Code 21: Front Right Wheel Speed Sensor Circuit Failure or Air Gap Fault
  • Code 25: Rear Left Wheel Speed Sensor Circuit Failure or Sensor Ring Damage
