Getting to Know Ford Diagnostic Codes
The OBD-II diagnostic trouble codes (DTCs) ranging from P0100 to P0199 specifically pertain to fuel and air metering issues within the vehicle’s powertrain. These codes provide insight into potential malfunctions or irregularities related to the fuel delivery system and air intake, allowing for targeted diagnosis and repair. If you encounter these codes, you should contact your local Ford dealership, an expert on Ford mechanical issues who carries certified Ford auto parts. However, here is a breakdown of these trouble codes and their implications and potential causes for your own knowledge.
- P0100 – Mass or Volume Air Flow “A” Circuit Malfunction This code indicates a malfunction within the mass airflow sensor circuit, which measures the amount of air entering the engine. Potential causes may include a faulty mass airflow sensor, damaged wiring, or a defective connector.
- P0101 – Mass or Volume Air Flow “A” Circuit Range/Performance Problem This trouble code suggests that the mass airflow sensor is experiencing a range or performance issue. It could stem from a dirty or contaminated sensor, a vacuum leak, or a malfunctioning sensor.
- P0102 – Mass or Volume Air Flow “A” Circuit Low Input This code points to a low input signal from the mass airflow sensor, potentially caused by a sensor malfunction, a clogged air filter, or a faulty intake air temperature sensor.
- P0103 – Mass or Volume Air Flow “A” Circuit High Input Conversely, this code signifies a high input signal from the mass airflow sensor, which could result from issues such as a malfunctioning sensor, a vacuum leak, or a restricted air intake system.
- P0104 – Mass or Volume Air Flow “A” Circuit Intermittent An intermittent circuit malfunction within the mass airflow sensor system triggers this trouble code, indicating potential issues with the sensor wiring, connections, or the sensor itself.
- P0105 – Manifold Absolute Pressure/Barometric Pressure Circuit Malfunction This code relates to a malfunction within the manifold absolute pressure (MAP) sensor or the barometric pressure sensor circuit. Potential causes include a faulty sensor, wiring issues, or a defective connector.
- P0106 – Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance Problem A range or performance issue within the MAP sensor or barometric pressure sensor circuit triggers this code, potentially stemming from sensor malfunctions or irregularities.
- P0107 – Manifold Absolute Pressure/Barometric Pressure Circuit Low Input This code indicates a low input signal from the MAP sensor or barometric pressure sensor, potentially caused by sensor malfunctions, wiring issues, or a restricted intake manifold.
- P0108 – Manifold Absolute Pressure/Barometric Pressure Circuit High Input Conversely, this trouble code signifies a high input signal from the MAP sensor or barometric pressure sensor, potentially resulting from sensor malfunctions, wiring issues, or a restricted intake manifold.
- P0109 – Manifold Absolute Pressure/Barometric Pressure Circuit Intermittent An intermittent circuit malfunction within the MAP sensor or barometric pressure sensor system triggers this code, indicating potential issues with the sensor wiring, connections, or the sensor itself.
- P0110 – Intake Air Temperature Circuit Malfunction Bank 1 This code pertains to a malfunction within the intake air temperature sensor circuit for bank 1, potentially caused by a faulty sensor, wiring issues, or a defective connector.
- P0111 – Intake Air Temperature Circuit Range/Performance Problem Bank 1 A range or performance issue within the intake air temperature sensor circuit for bank 1 triggers this trouble code, potentially stemming from sensor malfunctions or irregularities.
- P0112 – Intake Air Temperature Circuit Low Input Bank 1 This code indicates a low input signal from the intake air temperature sensor circuit for bank 1, potentially caused by sensor malfunctions, wiring issues, or a defective connector.
- P0113 – Intake Air Temperature Circuit High Input Bank 1 Conversely, this trouble code signifies a high input signal from the intake air temperature sensor circuit for bank 1, potentially resulting from sensor malfunctions, wiring issues, or a defective connector.
- P0114 – Intake Air Temperature Circuit Intermittent Bank 1 An intermittent circuit malfunction within the intake air temperature sensor system for bank 1 triggers this code, indicating potential issues with the sensor wiring, connections, or the sensor itself.
These trouble codes represent a comprehensive range of fuel and air metering-related issues that the OBD-II system can detect. It is important to note that addressing these codes may require thorough diagnosis by a qualified automotive technician at your local Ford dealership who carries certified Ford auto parts to pinpoint the precise cause of the malfunction and to carry out the necessary repairs.
