P1190 Dodge Code - Throttle Inlet Pressure Sensor High
Quick Answer
The P1190 diagnostic trouble code (DTC) for Dodge vehicles relates to the Throttle Inlet Pressure Sensor High. Common causes include Faulty throttle inlet pressure sensor: A malfunctioning sensor can provide inaccurate readings, leading to the high-pressure indication, Clogged air filter: A dirty or clogged air filter can restrict airflow, causing the throttle inlet pressure to increase, Vacuum leaks: Leaks in the vacuum system can disrupt pressure readings and trigger the P1190 code. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1190 Dodge Description
The P1190 diagnostic trouble code (DTC) for Dodge vehicles relates to the Throttle Inlet Pressure Sensor High. This code indicates that the throttle inlet pressure sensor is detecting a higher than normal pressure within the throttle system. The throttle inlet pressure sensor is responsible for monitoring the pressure of the air entering the engine through the throttle body. This information is crucial for the engine control unit (ECU) to accurately adjust the air-fuel mixture and optimize engine performance.
Common Causes of P1190 Dodge
- Faulty throttle inlet pressure sensor: A malfunctioning sensor can provide inaccurate readings, leading to the high-pressure indication.
- Clogged air filter: A dirty or clogged air filter can restrict airflow, causing the throttle inlet pressure to increase.
- Vacuum leaks: Leaks in the vacuum system can disrupt pressure readings and trigger the P1190 code.
- Intake manifold issues: Cracks or leaks in the intake manifold can affect pressure readings and cause the sensor to detect high pressure.
Symptoms of P1190 Dodge
- Reduced engine power: The vehicle may experience a loss of power or acceleration due to incorrect air-fuel mixture calculations.
- Rough idling: The engine may idle erratically or roughly, indicating a disruption in the air-fuel mixture.
- Decreased fuel efficiency: High throttle inlet pressure can lead to poor fuel efficiency as the engine struggles to maintain optimal performance.
- Check Engine Light: The P1190 code will trigger the Check Engine Light on the dashboard to alert the driver of a potential issue.
How to Fix P1190 Dodge
- Diagnose the issue: Use a diagnostic scanner to read the DTC and pinpoint the exact cause of the high throttle inlet pressure.
- Inspect the throttle inlet pressure sensor: Check the sensor for any signs of damage or malfunction and replace if necessary.
- Check the air filter: Inspect and replace the air filter if it is dirty or clogged to ensure proper airflow.
- Inspect the vacuum system: Check for any leaks in the vacuum lines or connections and repair as needed.
- Inspect the intake manifold: Check for cracks, leaks, or loose connections in the intake manifold and address any issues found.
Cost to Fix P1190 Dodge
The cost of repairing a P1190 code for a Dodge vehicle can vary depending on the specific cause of the issue. Replacing a faulty throttle inlet pressure sensor can cost between $100 to $300, while replacing an air filter typically costs between $20 to $50. Repairing vacuum leaks or intake manifold issues can range from $100 to $500, depending on the extent of the damage and labor involved. Overall, the total repair cost for addressing a P1190 code can range from $200 to $800, including parts and labor. It's important to note that labor rates and part prices can vary based on location, vehicle make and model, and the specific repair shop. It's recommended to obtain quotes from multiple auto repair shops to ensure a competitive price.
