What is P2173 : Engine Error code Causes Explained
The engine control module detects high idle airflow, which might cause throttle system performance concerns, causing the P2173 engine trouble code. A prompt diagnostic prevents engine damage and provides smooth, reliable performance in diverse driving circumstances.
How to Identify a DTCs Number
Understand, this trouble codes (DTCs) are 5 characters: 1 letter, 4 numbers. P-Powertrain indicates the fault code’s location. Generic or manufacturer-specific codes are indicated by the first digit. The second digit denotes the subsystem (7=transmission). The last two numbers describe the issue.
You can identify a DTC’s number like P2173 by connecting an OBD-II scanner to the vehicle’s diagnostic port, retrieving stored trouble codes, and confirming the exact alphanumeric code displayed, which corresponds to the detected fault.
Causes of P2173 Error Code:
- Vacuum leaks:
Leaks in the intake manifold or vacuum hoses can disrupt the air intake, triggering the code. - Faulty throttle body:
A dirty or faulty throttle body can misposition the throttle plate, causing irregular airflow. - Defective throttle position sensor (TPS):
A faulty TPS can misreport throttle position, leading to incorrect airflow readings. - Malfunctioning accelerator pedal position sensor.
Issues with the sensor that reads pedal position can contribute to the problem. - Wiring harness issues:
Damaged or corroded wires in the throttle body circuit can disrupt ECM communication. - ECM malfunction:
In some cases, a faulty ECM itself can misinterpret the data and trigger the code. - Brake vacuum issues:
Brake vacuum system issues can alter intake manifold pressure, triggering this code. - Improper throttle actuator calibration:
An uncalibrated throttle actuator may misposition the throttle plate.
Risk Level of P2173 Error Code:
The high risk level of the P2173 engine error code indicates a severe issue where the engine control module detects an abnormally high airflow into the intake manifold, often linked to throttle actuator or sensor malfunctions.
Ignoring this code can lead to catalytic converter damage and increased repair costs, so immediate attention is necessary.
Common Car Brands Affected by P2173 Code:
The P2173 code can affect various vehicles, it is most commonly associated with:
- Chrysler
- Jeep
- Dodge
