Is your Ford vehicle displaying a P2199 code? If so, you may be facing a problem related to the Intake Air Temperature (IAT) Sensor 1-2 Voltage Correlation. This code is set when the Powertrain Control Module (PCM) detects that the Intake Air Temperature Sensor 1-2 signals do not agree during the Continuous Control Monitor (CCM) test. Understanding the root cause of the Ford P2199 code is important to make the appropriate repairs and get your Ford back on the road.
Causes and Solutions for Ford P2199 Code
| Cause | Solution |
|---|---|
| IAT Sensor 1 connector is damaged or has high resistance | Replace the IAT Sensor 1 connector |
| IAT Sensor 1 signal circuit has a high resistance condition | Repair the IAT Sensor 1 signal circuit |
| IAT Sensor 1 is damaged or it has failed | Replace the IAT Sensor 1 |
| IAT Sensor 2 connector is damaged or has high resistance | Replace the IAT Sensor 2 connector |
If your Ford is displaying the P2199 code, it is important to diagnose and repair the issue as soon as possible. The P2199 code indicates that the Intake Air Temperature Sensor 1-2 signals are not agreeing during the Continuous Control Monitor test, which means that there is a problem somewhere in the system. This can be caused by an issue with the IAT Sensor 1 connector, a high resistance condition in the IAT Sensor 1 signal circuit, a damaged or failed IAT Sensor 1, or a damaged or high resistance IAT Sensor 2 connector. To properly diagnose and repair the issue, it is important to identify the root cause and take the necessary steps to fix it. This can include replacing connectors, repairing signal circuits, or replacing IAT Sensors.
Replacing IAT Sensor 1 Connector
If the P2199 code is being caused by a damaged or high resistance IAT Sensor 1 connector, the best solution is to replace the connector. This can be done by disconnecting the connector from the IAT Sensor 1 and wiring it to a new connector. It is important to ensure that the new connector is securely fastened and that the connection is free from any corrosion or debris. Once the new connector is installed, the system should be tested to ensure that the issue has been resolved.
Repairing IAT Sensor 1 Signal Circuit
If the P2199 code is being caused by a high resistance condition in the IAT Sensor 1 signal circuit, the best solution is to repair the circuit. This can be done by using a multimeter to identify any breaks, shorts, or other issues in the circuit. If any issues are identified, they should be repaired or replaced as necessary. Once any repairs or replacements have been completed, the system should be tested to ensure that the issue has been resolved.
Replacing IAT Sensor 1
If the P2199 code is being caused by a damaged or failed IAT Sensor 1, the best solution is to replace the sensor. This can be done by disconnecting the old sensor and wiring it to a new sensor. It is important to ensure that the new sensor is securely fastened and that the connection is free from any corrosion or debris. Once the new sensor is installed, the system should be tested to ensure that the issue has been resolved.
Replacing IAT Sensor 2 Connector
If the P2199 code is being caused by a damaged or high resistance IAT Sensor 2 connector, the best solution is to replace the connector. This can be done by disconnecting the connector from the IAT Sensor 2 and wiring it to a new connector. It is important to ensure that the new connector is securely fastened and that the connection is free from any corrosion or debris. Once the new connector is installed, the system should be tested to ensure that the issue has been resolved.
Conclusion: Resolving the Ford P2199 Code
The Ford P2199 code is set when the Powertrain Control Module detects that the Intake Air Temperature Sensor 1-2 signals do not agree during the Continuous Control Monitor test. This code can be caused by an issue with the IAT Sensor 1 connector, a high resistance condition in the IAT Sensor 1 signal circuit, a damaged or failed IAT Sensor 1, or a damaged or high resistance IAT Sensor 2 connector. To properly diagnose and repair the issue, it is important to identify the root cause and take the necessary steps to fix it. This can include replacing connectors, repairing signal circuits, or replacing IAT Sensors. The Ford P2199 code should be properly diagnosed and repaired in order to keep your Ford vehicle running smoothly.
