DTC codes / Ford diagnostic trouble codes

Ford diagnostic trouble codes

Codes Ford defines for its own vehicles. Other makes use the same numbers for different faults, so check that the code was read from a Ford vehicle.

P1000 Ford: OBD System Readiness Test Not Complete Powertrain P1001 Ford: KOER Test Cannot Be Completed Powertrain P1039 Ford: Vehicle Speed Signal Missing or Improper Powertrain P1051 Ford: Brake Switch Signal Missing or Improper Powertrain P1100 Ford: Mass Air Flow Sensor Intermittent Powertrain P1101 Ford: Mass Air Flow Sensor Out of Self-Test Range Powertrain P1105 Ford: Dual Alternator Upper Fault Powertrain P1106 Ford: Dual Alternator Lower Fault Manifold Absolute Pressure (MAP) Sensor Circuit Intermittent High Voltage Powertrain P1107 Ford: Dual Alternator Lower Circuit Malfunction Powertrain P1108 Ford: Dual Alternator Battery Lamp Circuit Malfunction Powertrain P1109 Ford: IAT B Sensor Intermittent Powertrain P1111 Ford: System Pass Powertrain P1112 Ford: Intake Air Temperature Sensor Intermittent Powertrain P1114 Ford: Intake Air Temperature B (IAT2) Circuit Low Input Powertrain P1115 Ford: Intake Air Temperature B (IAT2) Circuit High Input Powertrain P1116 Ford: Engine Coolant Temperature Sensor is Out of Self-Test Range Powertrain P1117 Ford: Engine Coolant Temperature Sensor Intermittent Powertrain P1118 Ford: Manifold Absolute Temperature Circuit Low Input Powertrain P1119 Ford: Manifold Absolute Temperature Circuit High Input Powertrain P1120 Ford: Throttle Position Sensor Out of Range Powertrain P1121 Ford: Throttle Position Sensor Inconsistent with Mass Air Flow Sensor Powertrain P1122 Ford: Throttle Position TP Sensor Circuit Intermittent Low Voltage Powertrain P1123 Ford: Throttle Position Sensor In Range But Higher Than Expected Powertrain P1124 Ford: Throttle Position Sensor Out of Self-Test Range Powertrain P1125 Ford: Throttle Position Sensor Intermittent Powertrain P1127 Ford: Exhaust Not Warm Enough Downstream O2 Sensor Not Tested Powertrain P1128 Ford: Upstream Heated Oxygen Sensor Signals Reversed Powertrain P1129 Ford: Downstream Heated Oxygen Sensor Signals Reversed Powertrain P1130 Ford: Lack of Upstream Heated Oxygen Sensor Switch Adaptive Fuel Limit Bank 1 Powertrain P1131 Ford: Lack of Upstream Heated Oxygen Sensor Switch Sensor Indicates Lean Bank 1 Powertrain P1132 Ford: Lack of Upstream Heated Oxygen Sensor Switch Sensor Indicates Rich Bank 1 Powertrain P1133 Ford: Bank 1 Fuel Control Shifted Lean Powertrain P1134 Ford: Bank 1 Fuel Control Shifted Rich Powertrain P1135 Ford: Pedal Position Sensor A Circuit Intermittent Powertrain P1137 Ford: Lack of Downstream Heated Oxygen Sensor Switch Sensor Indicates Lean Bank 1 Powertrain P1138 Ford: Lack of Downstream Heated Oxygen Sensor Switch Sensor Indicates Rich Bank 1 Powertrain P1139 Ford: Water In Fuel Indicator Circuit Malfunction Powertrain P1140 Ford: Water In Fuel Condition Powertrain P1141 Ford: Fuel Restriction Indicator Circuit Malfunction Powertrain P1142 Ford: Fuel Restriction Condition Powertrain P1150 Ford: Lack of Upstream Heated Oxygen Sensor Switch Adaptive Fuel Limit Bank 2 Powertrain P1151 Ford: Lack of Upstream Heated Oxygen Sensor Switch Sensor Indicates Lean Bank 2 Powertrain P1152 Ford: Lack of Upstream Heated Oxygen Sensor Switch Sensor Indicates Rich Bank 2 Powertrain P1153 Ford: Bank 2 Fuel Control Shifted Lean Powertrain P1154 Ford: Bank 2 Fuel Control Shifted Rich Powertrain P1155 Ford: Alternative Fuel Controller Powertrain P1157 Ford: Lack of Downstream Heated Oxygen Sensor Switch Sensor Indicates Lean Bank 2 Powertrain P1158 Ford: Lack of Downstream Heated Oxygen Sensor Switch Sensor Indicates Rich Bank 2 Powertrain P1168 Ford: Fuel Rail Sensor In-Range Low Failure Powertrain P1169 Ford: Fuel Rail Sensor In-Range High Failure Powertrain P1170 Ford: ESO Engine Shut Off Solenoid Fault Powertrain P1171 Ford: Rotor Sensor Fault Powertrain P1172 Ford: Rotor Control Fault Powertrain P1173 Ford: Rotor Calibration Fault Powertrain P1174 Ford: Cam Sensor Fault Powertrain P1175 Ford: Cam Control Fault Powertrain P1176 Ford: Cam Calibration Fault Powertrain P1177 Ford: Synchronization Fault Powertrain P1180 Ford: Fuel Delivery System Malfunction Low Powertrain P1181 Ford: Fuel Delivery System Malfunction High Powertrain
